WHAT DETERMINES A PROTOTYPE OR UNTRIED FEATURE The cylinder on the left is the standard cylinder that has been manufactured for many years and has stood the test of time. All that has been done to manufacture the cylinder on the right is to increase size, otherwise, everything else is the same, thus it is a prototype with untried features. Accordingly, the stresses and strains will be multiples of the original. In other words a failure waiting to happen.

GENERAL CONSIDERATIONS PUBLIC LIABILITY - 2 ONE MUST THEN CONSIDER THE NECESSITY TO INCLUDE ANY OR ALL OF THE FOLLOWING EXTENSIONS OF COVER: ARREST, ASSAULT, DISCHARGE AND DEFAMATION EMERGENCY MEDICAL EXPENSES PREVENTION OF ACCESS LEGAL DEFENCE COSTS TRESSPASS OR NUISANCE; REMOVAL OF SUPPORT (LATERAL OR VERTICAL) COULD BE AN EXTENSION, HOWEVER THE TERMS OF THIS COVER DIFFERS CONSIDERABLY FROM THE BASIC COVER, THUS IT IS DESIREABLE TO ISSUE A SEPARATE SECTION OR POLICY. THIS COVER WILL BE DISCUSSED SEPERATELY.

PREMIUM COMPUTATION CONTRACT WORKS GENERAL - 1 UNDERWRITING IS A SCIENCE AND NOT MERELY A RULE OF THUMB; THE UNDERWRITER WHO RELIES ON GUESSWORK MAY BE LUCKY FOR A PERIOD BUT WILL SOON COME SHORT; ONE CANNOT ASSUME THAT A SINGLE RATE WOULD APPLY TO ALL AND ANY PROJECT, NO MATTER HOW SLIGHT, THERE ARE ALWAYS DIFFERENCES WHICH COULD MAKE A VAST DIFFERENCE TO THE RATE CHARGED; ACCORDINGLY EACH RISK MUST BE UNDERWRITTEN ON ITS OWN MERITS AND PECULIARITIES WITH EACH ASPECT BEING GIVEN INDIVIDUAL CONSIDERATION; WE THEN CALCULATE INDIVIDUAL RATES FOR THE CIVIL, STRUCTURAL,ELECTRICAL & MECHANICAL AND LIABILITY RISKS; NO, I AM NOT GOING TO GIVE YOU BASIS RATES, BUT I WILL SUGGEST METHODS OF CALCULATION. THE BASIS RATES ARE FOR EACH UNDERWRITING HOUSE TO DETERMINE THEMSELVES.

PREMIUM COMPUTATION CONTRACT WORKS GENERAL - 2 IT MUST BE APPRECIATED THAT PERILS OF THE ENVIRONMENT HAVE A DIFFERENT IMPACT ON EACH OF THE CONSTRUCTION DISCIPLINES; FOR EXAMPLE, EXCESSIVE RAINFALL MAY NOT BE AS CRITICAL TO A PARTLY CONSTRUCTED STRUCTURE AS IT WOULD TO FOUNDATION EXCAVATIONS, ON THE OTHER HAND WIND MAY NOT CAUSE MUCH DAMAGE TO AN EXCAVATION AS IT WOULD TO A STRUCTURE NOT ENTIRELY BRACED OR STEEL BEING LIFTED INTO POSITION A FURTHER PROBLEM WOULD BE WHEN A STRUCTURE IS NOT FULLY CLAD THUS CAUSING A WIND TUNNELL WITHOUT ANY EXIT; FIRE IS A HAZARD MORE SERIOUS WHERE THE BUILDING IS NEARING COMPLETION OR WHERE MACHINERY HAS BEEN INSTALLED OFTEN PACKING MATERIALS ARE NOT REMOVED FROM SITE. FIRE IS NOT THAT SERIOUS WHEN RELATED TO EXCAVATIONS OR FOUNDATIONS ONE COULD EXPECT MINIMAL DAMAGE;

PREMIUM COMPUTATION CONTRACT WORKS CIVIL WORKS 1 It is usual for there to be a specific rate % for each project type e.g.. ROADS, RAILWAY SYSTEMS, DAMS, SHAFT SINKING, AIRPORT RUNWAYS/APRONS, TUNNELLING AND THE LIKE; THE APPLICABLE RATE X (SAY 2.5%) MUST THEN BE APPORTIONED TO RISK CATEGORIES, FOR EXAMPLE, (THESE % ARE JUST AN ILLUSTRATION AND ARE NOT REALISTIC) STORM/WIND 45% FIRE/LIGHTNING/EXPLOSION 5% COLLAPSE/LANDSLIDE 40% THEFT/MALICIOUS DAMAGE 10%; NEXT ONE MUST DECIDE ON THE EXTENT OF THE RISK APPLICABLE TO EACH CATEGORY, THUS STORM AND WIND ARE 45% OF 2.5%= 1.125% BUT THE WORK IS BEING UNDERTAKEN DURING THE DRY SEASON THEREFORE THIS RISK IS REGARDED AS MINIMAL SAY 25% OF THE NORM, OUR RATE FOR THIS PORTION IS THUS 25% 1.125% = 0.281%; THE SAME CALCULATION IS CARRIED OUT FOR EACH OF THE OTHER CATEGORIES OF THE RATE X;

PREMIUM COMPUTATION CONTRACT WORKS CIVIL WORKS 2 THE NEXT PART OF THE CALCULATION IS TO TAKE INTO ACCOUNT THE PERIOD ON RISK, THIS MAY NOT ONLY BE THE CONSTRUCTION PERIOD, BUT THE RISK MAY CONTINUE UNTIL TAKE-OVER OF THE COMPLETED PROJECT AS IN THE CASE OF A TURNKEY PROJECT; IT MUST BE REMEMBERED THAT IF TAKE-OVER IS TO BE DELAYED UNTIL FINAL COMPLETION, THEN THE CIVIL RISK WILL BE EXPOSED FOR A PERIOD THAT MUST BE DETERMINED (DURING CONSTRUCTION AND THEREAFTER UNTIL TAKEOVER); FINALLY THERE MUST BE A CHARGE FOR THE MAINTENANCE PERIOD DEPENDING ON THE NATURE OF MAINTENANCE COVER REQUIRED IN TERMS OF THE CONTRACT; THE CUMULATIVE RATE IS THEN APPLIED TO THE CIVIL PORTION OF THE CONTRACT VALUE TO PRODUCE A PREMIUM.

PREMIUM COMPUTATION CONTRACT WORKS STRUCTURAL WORKS 1 There is a specific rate % for each project type e.g.. RESIDENTIAL BUILDINGS, OFFICE BLOCKS, HOTELS, HOSPITALS, SHOPPING MALLS, BRIDGES, FACTORY PREMISES, WATER TOWERS CHIMNEYS AND THE LIKE; THE APPLICABLE RATE X (SAY 1%) MUST THEN BE APPORTIONED TO RISK CATEGORIES, FOR EXAMPLE, (THESE % ARE JUST AN ILLUSTRATION AND ARE NOT REALISTIC) STORM/WIND 20% FIRE/LIGHTNING/EXPLOSION 30% COLLAPSE/LANDSLIDE 35% THEFT/MALICIOUS DAMAGE 15%; NEXT ONE MUST ONE MUST DECIDE ON THE EXTENT OF THE RISK APPLICABLE TO EACH CATEGORY, THUS FIRE ETC. ARE 30% OF X(X BEING SAY 1%) (30%X)= 0.3% BUT THE WORK IS BEING UNDERTAKEN OUT OF THE LIGHTNING SEASON AND ALL PACKING MATERIALS ARE REMOVED FROM THE BUILDING THEREFORE THIS RISK IS REGARDED AS MINIMAL SAY 20% OF THE NORM, OUR RATE FOR THIS PORTION IS THUS 20% OF 0.3% =0.06%; THE SAME CALCULATION IS CARRIED OUT FOR EACH OF THE OTHER CATEGORIES OF THE RATE X;

PREMIUM COMPUTATION CONTRACT WORKS STRUCTURAL WORKS 2 THE NEXT PART OF THE CALCULATION IS TO TAKE INTO ACCOUNT THE PERIOD ON RISK, THIS MAY NOT ONLY BE THE CONSTRUCTION PERIOD, BUT THE RISK MAY CONTINUE UNTIL TAKE-OVER OF THE COMPLETED PROJECT AS IN THE CASE OF A TURNKEY PROJECT; IT MUST BE REMEMBERED THAT IF TAKE-OVER IS TO BE DELAYED UNTIL FINAL COMPLETION, THEN THE STRUCTURAL RISK WILL BE AT RISK FOR AN EXTENDED PERIOD WHICH MUST BE DETERMINED ESPECIALLY IF MACHINERY IS TO BE INSTALLED BEFORE TAKE-OVER OF THE COMPLETED STRUCTURE THUS AN ADDITIONAL CHARGE FOR THE EXTENDED PERIOD AFTER CONSTRUCTION IS WARRANTED; FINALLY THERE MUST BE A CHARGE FOR THE MAINTENANCE PERIOD DEPENDING ON THE NATURE OF MAINTENANCE COVER REQUIRED IN TERMS OF THE CONTRACT; THE CUMULATIVE RATE IS THEN APPLIED TO THE STRUCTURAL PORTION OF THE CONTRACT VALUE TO PRODUCE A PREMIUM.

PREMIUM COMPUTATION CONTRACT WORKS ELECTRICAL & MECHANICAL WORKS - 1 UNLIKE CIVIL AND STRUCTURAL RATING, THE ELECTRICAL AND MECHANICAL RATE IS BUILT UP OVER A NUMBER OF FACTORS, THESE ARE: HANDLING AND STATIC TESTING TESTING AND RUNNING FIRE AND SPECIAL PERILS DURING CONSTRUCTION FIRE AND SPECIAL PERILS DURING TESTING ENVIRONMENT BENEFICIAL USE IF REQUIRED IN TERMS OF CONTRACT MAINTENANCE ONCE AGAIN BASED ON THE REQUIRED COVER; EACH OF THESE RATE COMPONENTS HAS ITS OWN SPECIFIC RATE WHICH EXCEPT FOR THE HANDLING AND STATIC TESTING RATE ARE ADJUSTED TO TAKE IN TO ACCOUNT THE PARTICULAR PERIOD OF COVER AND RISK FACTOR. EACH OF THESE RATE COMPONENTS ARE EXPLAINED AS FOLLOWS:

PREMIUM COMPUTATION CONTRACT WORKS ELECTRICAL & MECHANICAL WORKS - 2 HANDLING AND STATIC TESTING: THIS RATE COMPONENT ALLOWS FOR PRE ERECTION STORAGE ON SITE, MOVEMENT FROM STORAGE TO POINT OF ERECTION, HOISTING ONTO FOUNDATIONS, ASSEMBLY THEN NON ENERGISED TESTING TESTING AND RUNNING: IT IS AT THIS STAGE THAT POWER IS FIRST APPLIED TO THE MACHINE AND FEEDSTOCK INTRODUCED. EFFECTIVELY THIS COVER EQUATES TO MACHINERY BREAKDOWN COVER. THE PERIOD IS USUALLY RESTRICTED TO 30 DAYS ON WHICH THE MACHINERY IS OPERATED FOR TESTING PURPOSES. IT IS ASSUMED THAT ALL MANUFACTURERS SAFETY REQUIREMENTS AND COMMISSIONING PROCEDURES WILL BE ADHERED TO AND THAT SAFETY DEVICES WILL NOT BE OVERRIDDEN OR NULLIFIED. IT IS USUAL THAT WHERE THERE ARE ANY UNTRIED FEATURES OR PROTOTYPES THAT TESTING COVER WILL BE EXCLUDED; TESTING COVER IS USUALLY ONLY GIVEN ON NEW MACHINERY;

PREMIUM COMPUTATION CONTRACT WORKS ELECTRICAL & MECHANICAL WORKS - 3 FIRE AND SPECIAL PERILS: THESE RISKS ARE NO DIFFERENT TO THOSE GIVEN UNDER A FIRE OR ASSETS POLICY, ACCORDINGLY, THE RATE SHOULD BE SIMILAR TO THE STANDARD FIRE POLICY. THIS COMPONENT IS DIVIDED INTO TWO CATEGORIES, NAMELY DURING CONSTRUCTION AND THEN DURING TESTING AND RUNNING. A LESSER RATE SHOULD BE APPLIED TO THE CONSTRUCTION PERIOD POSSIBLY 50% OF FIRE & PERILS RATE, WHEREAS THE FULL RATE SHOULD BE APPLIED TO THE TESTING PERIOD. IN BOTH INSTANCES THE RATE SHOULD BE ADJUSTED FOR THE PERIOD OF COVER; ENVIRONMENT: THIS COMPONENT TAKES INTO CONSIDERATION THE RISKS OF THEFT, MALICIOUS DAMAGE GEOTECHNIC AND HYDROLOGY RISKS AND A VARIETY OF OTHER MINOR PERILS.

UNDERWRITING CRITERIA PUBLIC LIABILITY - 1 THIS SECTION OF THE POLICY PROVIDES FOR LIABILITY TO THIRD PARTIES IN RESPECT OF LOSS OF OR DAMAGE TO PROPERTY OR PERSONAL INJURIES OR DEATH OF PERSONS NOT BEING EMPLOYEES OR THE FAMILY OF THE INSURED PARTY; WE ARE NOT TALKING ABOUT A SEPARATE POLICY, BUT AS A SECTION TO A CONSTRUCTION POLICY, THUS ANY LIABILITY INCURRED SHOULD ORIGINATE AT THE CONTRACT SITE IN CONNECTION WITH SITE ACTIVITIES DURING THE PERIOD OF INSURANCE; TO PROVIDE FOR ANY WIDER COVER A GENERAL LIABILITY POLICY SHOULD BE TAKEN OUT IN THE ACCIDENT DEPARTMENT; THERE ARE TWO BASES OF COMPUTING PUBLIC LIABILITY PREMIUMS EITHER ON: LIMIT OF LIABILITY, OR CONTRACT VALUE; NEITHER BASIS CAN BE CONSIDERED SUPERIOR TO THE OTHER, EFFECTIVELY THE PREMIUM SHOULD BE THE SAME;

UNDERWRITING CRITERIA PUBLIC LIABILITY - 2 RECOGNISING THAT THERE ARE TWO ACCEPTABLE BASES, WHAT FACTORS SHOULD BE TAKEN INTO CONSIDERATION IN COMPUTING THE PREMIUM; ALL THOSE LISTED HEREUNDER WILL EITHER BE PROMINENT IN THE PREMIUM CALCULATION OR OF LITTLE OR NO EFFECT, EACH MUST BE CONSIDERED ON MERITS: IS THE SITE A GREEN FIELDS OR BROWN FIELDS SITE, IS THERE A POSSIBILITY OF DAMAGE TO EXISTING PROPERTY EITHER ON-SITE OR ON SITES ADJACENT TO THE CONTRACT SITE, IS THE RISK LOCATION IN/OUT OF TOWN ARE THERE ANY PUBLIC SERVICES IN THE VICINITY, ARE ANY EXPLOSIVES TO BE USED, DEPTH OF EXCAVATION/ GEOTECHNIC RISKS, EXPERTISE AND TRACK RECORD OF CONTRACTOR AND DESIGN ENGINEER, WORKING METHODS AND DESIGN, PLAN OR SPECIFICATION, RISK MANAGEMENT; THE POTENTIAL RISK OF SPREAD OF FIRE TO ADJACENT PROPERTIES EITHER ON SITE OR IN THE PROXIMITY THERETO

UNDERWRITING CRITERIA THIRD PARTY LIABILITY - 3 EXTENSIONS OF COVER ARE THE SELECTED EXTENSIONS OF COVER TO BE WITHIN THE OVERALL LIMIT OF INDEMNITY OR ARE THEY TO HAVE SEPARATE LIMITS OF INDEMNITY?

PREMIUM COMPUTATION PUBLIC (THIRD PARTY) LIABILITY - 3 ARREST, ASSAULT, DISCHARGE AND DEFAMATION, EMERGENCY MEDICAL EXPENSES, PREVENTION OF ACCESS, LEGAL DEFENCE COSTS, TRESSPASS OR NUISANCE. THE COMPUTATION OF THE REMOVAL OF SUPPORT RISK IS UNDERTAKEN ON MUCH THE SAME BASIS, BUT THE BASIC RATE IS MUCH HIGHER THAN FOR STANDARD LIABILITIES; WE HAVE NOT MENTIONED THE RISKS APPLICABLE TO IMPLOSION OF BUILDINGS BEFORE NOW, HOWEVER, THESE ARE MUCH MORE ONEROUS THAN ORDINARY LIABILITIES OR REMOVAL OF SUPPORT LIABILITIES, BUT WE DO NOT BELIEVE THESE RISKS TO BE APPROPRIATE TO THIS DISCUSSION.

CONTRACTORS LIABILITIES A CONTRACTOR CAN INCUR LIABILITIES FROM MANY SOURCES THUS HE NEEDS A PACKAGE OF LIABILITY COVERS OVER AND ABOVE THAT GIVEN UNDER A CONTRACT WORKS OR CONSTRUCTION POLICY. IT CAN EVEN BE SAID THAT A COMPREHENSIVE LIABILITY PACKAGE SHOULD INCLUDE HIS POTENTIAL CONSTRUCTION RISKS LIABILITIES. ACCORDINGLY, THE CONSTRUCTION POLICY SHOULD EXCLUDE THE CONTRACTORS LIABILITIES, HOWEVER, WHERE OTHER PARTIES ARE INVOLVED ON THE CONSTRUCTION SITE THEY MAY NEED TO BE COVERED FOR CONSTRUCTION LIABILITIES. THE QUESTION THEN ARISES, SHOULD THE CONSTRUCTION POLICY WAIVE SUBROGATION RIGHTS AGAINST THE CONTRACTOR?

CONTRACTORS LIABILITY POLICY -1 LET US EXAMINE THE RECOMMENDED COMPONENTS TO A COMPREHENSIVE CONTRACTORS LIABILITY POLICY: IT IS UNUSUAL FOR THIS TYPE OF POLICY TO BE UNDERWRITTEN IN THE CONSTRUCTION OR ENGINEERING DEPARTMENT IT IS MORE AN ACCIDENT DEPARTMENT RISK, FIRSTLY, WE MUST UNDERSTAND THAT THESE COVERS CAN EITHER BE BASED ON CLAIMS MADE OR CLAIMS INCURRED THE FORMER BASIS RECOGNISES THAT ANY CLAIM LODGED AGAINST THE INSURED DURIUNG A PARTICULAR PERIOD OF INSURANCE, IRRESPECTIVE OF WHEN THE TRIGGERING EVENT OCCURRED, SHALL BE REGARDED AS VALID AS LONG AS IT FALLS WITHIN THE AMBIT OF THE POLICY, ON THE OTHER HAND ON A CLAIMS INCURRED BASIS ANY CLAIM LODGED AGAINST THE INSURED MUST THEN REVERT TO THE POLICY IN FORCE AT THE TIME THAT THE TRIGGERING EVENT OCCURRED;

CONTRACTORS LIABILITY POLICY -2 THE FOLLOWING ARE THE MORE COMMON SECTIONS TO A COMPREHENSIVE Contractors Liability Policy: PUBLIC LIABILITY -GENERAL AND CONTRACTING LIABILITIES PRODUCTS LIABILITY PRODUCTS MANUFACTURED OR SUPPLIED EMPLOYERS LIABILITY INJURY OR SICKNESS ARISING OUT OF EMPLOYMENT, PROFESSIONAL INDEMNITY BREACH OF PROFESSIONAL ACTIVITY OR DUTY, MOTOR EXCESS OF LOSS LIABILITY DUE TO LOSS OR ACCIDENT DURING THE PERIOD OF THE POLICY, PRODUCTS GUARANTEE LIABILITY FOR PRODUCTS SUPPLIED, SOLD,INSTALLED ETC., PRODUCT RECALL WHERE SUCH PRODUCT MAY CAUSE INJURY OR DAMAGE, CARRIERS LIABILITY DAMAGE ARISING OUT OF THE CARRIAGE OF GOODS INCLUDING CONSEQUENTIAL LOSS,

CONTRACTORS LIABILITY POLICY -3 LIABILITY SECTIONS CONTINUED: PLANT HIRE LIABILITY LEGAL LIABILITY FOR LOSS OR DAMAGE IN TERMS OF A HIRE AGREEMENT INCLUDING CONSEQUENTIAL LOSS, PURE ECONOMIC LOSS CLAIMS MADE DURING THE PERIOD OF INSURANCE OTHER THAN FOR PROFESSIONAL SERVICES FOR COMPENSATION IN TORT, DELICT OR STATUTE; THE EXTENSIONS OF COVER ARE SIMILAR TO THOSE UNDER THE MORE SPECIFIC CONSTRUCTION POLICY LIABILITY SECTION; WHERE A MORE SPECIFIC POLICY INCLUDING LIABILITIES HAS BEEN TAKEN OUT THE CONTRACTORS LIABILITY POLICY WILL ONLY PROVIDE LIABILITY FOR DIFFERENCES IN COVER OR LIMIT OF INDEMNITY, IT WILL NOT BE BROUGHT IN TO CONTRIBUTION WITH THE MORE SPECIFIC POLICY;

CONSTRUCTION PLANT INSURANCE - 1 WHAT COMPRISES PLANT UNDER A CONSTRUCTION POLICY? MOBILE PLANT AND EQUIPMENT: MOBILE CRANES, CRAWLER CRANES, DUMP TRUCKS, BULLDOZERS, ROAD SCRAPERS, BACKACTORS, EXCAVATORS, ROAD TANKERS (WATER, FUEL OR BITUMEN), ROAD ROLLERS; NON MOBILE PLANT AND EQUIPMENT: CONCRETE BATCH PLANT, CONCRETE MIXERS AIR COMPRESSORS, ELECTRICITY GENERATING PLANT, MINI SUB- STATIONS, CONVEYOR SYSTEMS, TOWER CRANES, WELDING GENERATORS AND TRANSFORMERS; MINING PLANT AND EQUIPMENT: DRAGLINES, EXCAVATORS, JUMBO DRILL RIGS, MINING SCOOPS, DUMP TRUCKS AND MINE WINDERS LONG WALL COAL CUTTERS, MINING SCOOPS AND TUNNELL BORING MACHINES;

CONSTRUCTION PLANT INSURANCE - 2 CLASSES OF OWNERSHIP: CONTRACTORS WHO OWN PLANT FOR CONTRACTING WORK; PLANT OWNED FOR OWN USE SUCH AS MINING OPERATIONS, INDUSTRIAL WORKS AND SERVICE INDUSTRIES; PLANT HIRE COMPANIES FOR HIRE TO CUSTOMERS; VIRTUALLY EVERY PROJECT REQUIRES PLANT OF ONE TYPE OR ANOTHER, LET US CONSIDER THE VARIOUS CATEGORIES OF PLANT: CONSTRUCTION CONTRACTORS: BUILDING CONTRACTORS CONCRETE BATCH PLANT, CRANES MOBILE, CRAWLER AND TOWER, CONCRETE MIXERS, CONCRETE ESCALATORS, PUMPS CONCRETE AND WATER, EXCAVATORS, BACKACTORS AND THE LIKE ROAD CONSTRUCTION CONTRACTORS THESE CONTRACTORS USE A LARGE VARIETY OF PLANT SUCH AS, SCRAPERS, EXCAVATORS, ROLLERS, BULLDOZERS, BACKACTORS, MOBILE CRANES,AIR COMPRESSOR SETS, PAVING MACHINES ETC.;

CONSTRUCTION PLANT INSURANCE - 3 MINING OPERATIONS (MAINLY OPENCAST): EXCAVATORS, DRAGLINES, JUMBO DRILLS, EARTH MOVING TRUCKS, MINING SCOOPS, CONVEYOR SYSTEMS, CRUSHERS, CRANES, COMPRESSORS, DIESEL GENERATING PLANT ETC. IN SOME INSTANCES THE PLANT MAY INCLUDE MINE WINDERS OR TUNNELL BORING MACHINES; PLANT HIRE COMPANIES: THEIR PURPOSE IS AS A SERVICE TO CONSTRUCTION, MINING AND INDUSTRY, TO PROVIDE PLANT AND MACHINERY AS REQUIRED FOR A VARIETY OF JOBS. SOMETIMES THESE HIRE COMPANIES ARE A DIVISION WITHIN A CONSTRUCTION, MINING OR INDUSTRIAL COMPANY, THE PURPOSE OF WHICH IS TO SEPARATE THE COSTLY AND ONEROUS OWNERSHIP OF PLANT AND MACHINERY FROM THEIR CORE BUSINESS, WHETHER THIS BE CONSTRUCTION, MINING OR OTHER INDUSTRIAL ACTIVITY;

CONSTRUCTION PLANT INSURANCE 4 THE NEED FOR INSURANCE THIS TYPE OF PLANT & EQUIPMENT IS GENERALLY HIGH RISK, SUSCEPTIBLE TO IMPACT, FIRE, THEFT AND ELEMENTAL PERILS. WE ARE NOT SUGGESTING THAT THE USERS DO SO NEGLIGENTLY, CARELESSLY OR WITHOUT REGARD FOR POSSIBLE DANGER OR DAMAGE. PLANT IS USUALLY OPERATED BY A DEDICATED OPERATOR OR OPERATORS, THUS THE ONUS FOR ANY UNDUE OPERATION OF THE PLANT RESULTING IN DAMAGE COULD BE PEGGED AT THE DOOR OF AN INDIVIDUAL. IT MUST BE APPRECIATED THAT THIS TYPE OF PLANT HAS LARGE QUANTITIES OF FUEL OIL AND HYDRAULIC OIL BOTH OF WHICH ARE HIGHLY INFLAMABLE; DEPENDING ON THE TERRAIN IN WHICH IT WORKS TOPPLING OVER OR OVERTURNING IS A VERY REAL RISK; IN VIEW OF THE ELEMENT OF RISK WHICH IS HIGH & VARIED IT WOULD BE UNWISE NOT TO INSURE THE PLANT.

CONSTRUCTION PLANT INSURANCE 5 THE INSURANCE POLICY COVER THE COVER IS SIMILAR FOR ALL CLASSES OF OWNERSHIP AS THIS EQUIPMENT IS ESSENTIALLY FOR OUTDOOR USE, IT QUALIFIES FOR WHAT CAN BE TERMED ALL RISKS COVER. THIS DOES NOT MEAN THAT THERE ARE NO TERMS AND CONDITIONS APPLICABLE TO THE INSURANCE, INDEED THERE ARE LIMITING FACTORS TO THE COVER. THE COVER EMBRACES: ELECTRICAL AND MECHANICAL BREAKDOWN (OPTIONAL COVER) FIRE LIGHTNING EXPLOSION ELEMENTAL PERILS FLOOD THEFT MALICIOUS DAMAGE IMPACT COLLISION OVERTURNING UNINTENTIONAL OVERLOADING

CONSTRUCTION PLANT INSURANCE 6 THE INSURANCE POLICY EXCEPTIONS ALTHOUGH WE REFER TO THE COVER AS BEING ALL RISKS, NEVERTHELESS THERE ARE SOME EXCEPTIONS THESE ARE AS FOLLOWS: WEAR AND TEAR AND GRADUAL DETERIORATION; PENALTIES FOR DELAY AND GUARANTEES OF PERFORMANCE; LOSS OF USE; TYRES AND TUBES; EXPENDABLE PARTS AND TOOLS; THEFT NOT IDENTIFIABLE WITH A SPECIFIC INCIDENT; TANDEM OR MULTIPLE LIFTS; EXISTING DEFECTS, WILFUL ACTS OR NEGLIGENT ACTS; EXPERIMENTS OR INTENTIONAL OVERLOADING; WHILST BEING OPERATED BY A PERSON: UNDER THE INFLUENCE OF INTOXICATING LIQUOR OR DRUGS, AUTHORISED BY THE OWNER OR HIS RESPONSIBLE PERSON WHO IS NOT QUALIFIED TO OPERATE THE PLANT ELECTRICAL OR MECHANICAL BREAKDOWN (IF OPTION NOT REQUIRED);

CONSTRUCTION PLANT INSURANCE 7 HIRED-IN PLANT POLICY AMENDMENT THE POLICY WORDING IS GENERALLY SIMILAR WHETHER COVERING OWNED PLANT OR HIRED-IN PLANT, TO ACHIEVE THE ADJUSTMENT TO THE STANDARD POLICY THE FOLLOWING MEMORANDA ARE INCLUDED: A) THE INSUREDS LEGAL LIABILITY UNDER ANY HIRING AGREEMENT TO PAY COMPENSATION FOR PHYSICAL LOSS OF OR DAMAGE TO ANY INSURED HIRED-IN MACHINERY WHILST UNDER HIS CUSTODY OR CONTROL AT THE INSUREDS PREMISES DESCRIBED IN THE SCHEDULE HERETO; B) THE INSUREDS LEGAL LIABILITY UNDER ANY HIRING AGREEMENT TO PAY CONTINUING HIRE CHARGES IN CONSEQUENCE OF PHYSICAL LOSS OF OR DAMAGE TO THE INSURED HIRED-IN MACHINERY DESCRIBED IN THE SCHEDULE HERETO FOLLOWING INDEMNIFIABLE LOSS OR DAMAGE PROVIDED FOR IN A) ABOVE; AS PREVIOUSLY STATED THE POLICY REQUIRES THAT ANY HIRING AGREEMENT SHALL BE NO MORE ONEROUS THAN THE CPHA CONDITIONS.

CONSTRUCTION PLANT INSURANCE 6 HIRED IN/OUT PLANT & MACHINERY THIS PLANT AND EQUIPMENT IS HIRED IN/OUT UNDER SPECIFIC HIRING CONDITIONS. INSURERS PREFER THE CONDITIONS AS PUBLISHED BY THE PLANT HIRE ASSOCIATION KNOWN AS THE CPHA CONDITIONS. THE CPHA CONDITIONS ARE CONSIDERED TO BE THE MOST FAIR FROM BOTH THE OWNERS AND THE HIRERS POINTS OF VIEW. IN FACT, A POLICY COVERING HIRED PLANT OFTEN INCLUDES A MEMORANDUN WHICH STATES: THIS INSURANCE IS BASED ON HIRING AGREEMENTS NO MORE ONEROUS THAN THOSE PUBLISHED BY THE CONTRACTORS PLANT HIRE ASSOCIATION, SHOULD PLANT HAVE BEEN HIRED UNDER OTHER HIRING AGREEMENTS THEN ANY LOSS OR DAMAGE COVERED UNDER THIS POLICY WILL BE ADJUSTED AS IF THE CPHA CONDITIONS HAD BEEN IN FORCE

EMPLOYERS LIABILITY - 1 EMPLOYERS LIABILITY: TO WHOM DO THE EMPLOYERS HAVE A POTENTIAL RESPONSIBILITY TO PAY COMPENSATION FOR INJURIES OR DISEASE DUE TO THEIR OCCUPATION,UNDER WHAT LAW: PRIOR TO 1994 ALL EMPLOYEES EARNING LESS THAN A SPECIFIED AMOUNT, SPECIFIED IN TERMS OF THE WORKMANS COMPENSATION ACT (WCA), WERE CLASSED AS WORKMEN. THEY OR THEIR DEPENDANTS COULD CLAIM COMPENSATION UNDER THE ACT, BUT HAD NO LEGAL RIGHT TO SUE THEIR EMPLOYERS; THOSE WORKMEN EARNING IN EXCESS OF THE PRESCRIBED AMOUNT WERE IN TERMS OF THE ACT CLASSED AS NON- WORKMEN NON WORKMEN WERE PRECLUDED FROM CLAIMING COMPENSATION FOR OCCUPATIONAL INJURIES OR DISEASE, UNDER THE WORKMANS COMPENSATION ACT, BUT WERE ABLE TO CLAIM COMPENSATION FROM THEIR EMPLOYERS FOR SUCH INJURIES OR DISEASE, ACCORDINGLY, MOST EMPLOYERS TOOK OUT EMPLOYERS LIABILITY INSURANCE

EMPLOYERS LIABILITY - 2 IN 1994 THE COMPENSATION FOR OCCUPATIONAL INJURIES AND DISEASES ACT (130 OF 1993) WAS PROMULGATED, COMMONLY KNOWN AS THE COID ACT; IN TERMS OF THE ACT ALL EMPLOYEES (THE BENEFITS ARE PEGGED TO BE A DEFINED INCOME LEVEL) AND PRECLUDES EMPLOYEES FROM CLAIMING COMPENSATION FROM THEIR EMPLOYERS FOR INJURIES OR DISEASE ARISING OUT OF THEIR OCCUPATION, ONLY IN EXCEPTIONAL CASES WHERE EMPLOYMENT IS NOT CLASSIFIED AS EMPLOYEES ARE THEY FREE TO SUE THEIR EMPLOYER FOR COMPENSATION UNDER COMMON LAW FOR SUCH INJURIES OR DISEASES; THE COID ACT DEFINITION OF EMPLOYEE INCLUDES APPRENTICES AND LEARNERS, BUT NOT THOSE CONTRACTED TO CARRY OUT WORK FOR THE EMPLOYER OR THEIR SUB-CONTRACTORS; CONSEQUENTLY EMPLOYERS LIABILITY CLAIMS ARE RARE

EMPLOYERS LIABILITY - 3 UNDER A MODERN EMPLOYERS LIABILITY POLICY, DEATH AND BODILY INJURY INCLUDES DISEASE OR ILLNESS. THIS COVER IS UNLIKE PUBLIC LIABILITY POLICIES IN THAT PROPERTY DAMAGE IS NOT INCLUDED; IT IS IMPORTANT TO UNDERSTAND THAT UNDER THE USUAL EMPLOYERS LIABILITY, INJURY OR ILLNESS MUST OCCUR DURING THE PERIOD OF INSURANCE. THE CLAIM MAY BE MADE AND THE INSURERS LIABILITY ARISE MANY YEARS AFTER THE CAUSE OF THE ACTION, EVEN AFTER THE ORIGINAL INSURER IS OFF RISK. THIS EQUATES TO A CLAIMS INCURRED WORDING. THE INSURER WHO WAS ON RISK AT THE TIME THE CAUSE OCCURRED IS THE INSURER RESPONSIBLE FOR THE CLAIM.

EMPLOYERS LIABILITY - 4 IT IS RECOMMENDED THAT THIS CHAPTER (8) OF THE IISA CONSTRUCTION INSURANCE STUDY BOOK BE CAREFULLY READ THE COID ACT PROVIDES FOR COMPENSATION FOR DISABLEMENT CAUSED BY OCCUPATIONAL INJURIES OR DISEASES SUSTAINED OR CONTRACTED BY EMPLOYEES IN THE COURSE OF THEIR EMPLOYMENT, OR DEATH FROM SUCH INJURIES OR DISEASE. DISABLEMENT INCLUDES CONVENTIONAL BODILY INJURY UNDER A CONVENTIONAL EMPLOYERS LIABILITY POLICY; DISABLEMENT AS DEFINED BY COID MEANS TEMPORARY PARTIAL DISABLEMENT TEMPORARY TOTAL DISABLEMENT, PERMANENT DISABLEMENT OR SERIOUS DISFIGUREMENT; COID AFFORDS A MORE COMPREHENSIVE COVER THAN A NORMAL EMPLOYERS LIABILITY POLICY. UNDER AN EMPLOYERS LIABILITY POLICY, THE EMPLOYER HAS TO BE NEGLIGENT BEFORE A VALID CLAIM CAN ARISE. COID DOES NOT REQUIRE NEGLIGENCE ON THE PART OF THE EMPLOYER. IT IS SUFFICIENT FOR THE DISABLEMENT TO BE AS A RESULT OF AN ACCIDENT NOT NECESSARILY DUE TO NEGLIGENCE. THUS COID HAS A WIDER APPLICATION.

PROJECT 3 TO BE PRESENTED AT NEXT SESSION An Employee, let us call him Joe, while working on a machine in the production shop and, not wearing a safety belt slips and falls to the ground some 4 metres below and breaks his leg, it is a compound fracture. He is incapacitated for six weeks while the bone heals, he cannot attend work, but returns to work at the beginning of the seventh week, although, the sore on his leg has not completely healed. Some three weeks later, when the sore still has not healed he visits his Doctor again and the Doctor identifies that gangrene has set in and is at an advanced stage, unfortunately, the only remedy is to amputate his leg. How will he be compensated under the Coid Act, would he have been treated any different under a Employers Liability Policy? What would the Coid Act Commissioner say about the lack of Safety belt?

PROFESSIONAL INDEMNITY INSURANCE 1 THIS IS A CLASS OF LIABILITY INSURANCE; THE LAW RELATING TO DEFECTS IN BUILDINGS AND STRUCTURES AS WELL AS THAT RELATING TO ECONOMIC LOSS HAS BECOME ONEROUS TO CONTRACTORS, ENGINEERS, ARCHITECHTS, SURVEYORS AND OTHER PROFESSIONALS; AS A CONSEQUENCE PROFESSIONAL INDEMNITY INSURANCE HAS BECOME OF GREAT SIGNIFICANCE TO PROFESSIONAL BODIES; THE COVER IS ON A CLAIMS MADE BASIS IN OTHER WORDS IF A CLAIM IS FIRST MADE AGAINST AN INSURED SOME TIME AFTER THE OCCURRENCE OF THE EVENT THAT GAVE RISE TO THE CLAIM, THEN THE INSURER WHO IS CURRENTLY ON RISK SHALL BECOME LIABLE TO INDEMNIFY THE INSURED FOR THE CLAIM

PROFESSIONAL INDEMNITY INSURANCE 2 THE PRIMARY FUNCTION OF THE POLICY IS TO PROVIDE FOR FINANCIAL OR ECONOMIC LOSS IN OTHER WORDS LOSSES NOT ACCOMPANIED BY PHYSICAL DAMAGE OR BODILY INJURY; IT IS IMPORTANT TO FULLY DESCRIBE ALL THE ACTIVITIES OF THE INSURED IN THE RECITAL CLAUSE AS THE INDEMNITY APPLIES TO THE STATED BUSINESS AND NO OTHER FOR EXAMPLE DESIGN AND CONSTRUCT CONTRACTORS, ARCHITECHTS, DESIGN ENGINEERS ETC.; IT IS A LEGAL LIABILITY POLICY, THUS THE INSURERS OBLIGATION TO INDEMNIFY ONLY BECOMES PAYABLE ONCE THE INSURED HAS BEEN FOUND TO BE LEGALLY LIABLE; PROFESSIONAL INDEMNITY IS NOT A CONTRACT BASED ON MORAL OR COMMERCIAL CONSIDERATIONS

PROFESSIONAL INDEMNITY INSURANCE 3 COVER IS BASED ON BREACH OF PROFESSIONAL DUTY; THE CLAIM HAS TO BE MADE (AS PREVIOUSLY DISCUSSED) DURING THE PERIOD OF INSURANCE; COVER ENVISAGES CLAIMS ARISING OUT OF NEGLIGENT ACTS, ERRORS OR OMISSIONS THESE WORDS HAVE NEVER BEEN DEFINED, SOME LEGAL CASES TAKE THE VIEW THAT THEY REFER TO NEGLIGENCE ONLY, THERE ARE, OF COURSE, OTHER INTERPRETATIONS; IN THE CASE WIMPY CONSTRUCTION UK LTD. VS POOLE(1984) IT WAS HELD THAT THE TERM OMISSION ERROR OR NEGLIGENT ACT COVERED AN OMISSION OR ERROR WITHOUT NEGLIGENCE, EVEN THOUGH AN ANCILLARY CLAUSE IN THE POLICY REFERRED TO NEGLIGENT ACT, ERROR OR OMISSION

PROFESSIONAL INDEMNITY INSURANCE 4 THE DESIGN AND CONSTRUCT POLICY WORDING EXCLUDES ANY LIABILITY ARISING DUE TO THE INSURED (CONTRACTOR) HAVING GIVEN AN EXPRESS WARRANTY OR GUARANTEE THAT INCREASES THE INSUREDS LIABILITY. THIS EXCLUSION DOES NOT APPLY TO LIABILITY WHICH WOULD HAVE ATTACHED IN THE ABSENCE OF SUCH EXPRESS WARRANTY OR GUARANTEE; THE P.I. POLICY REFERS NOT ONLY TO THE INSURED NAMED IN THE SCHEDULE, BUT ALSO TO PREDECESSORS IN BUSINESS OR ANY EMPLOYEE OF THE INSURED; WHEN BUSINESSES AMALGAMATE OR SPLIT UP, THE APPLICATION OF THE PREDECESSORS TO BUSINESS CLAUSE CAN GIVE RISE TO DIFFICULTIES; WHERE THERE HAS BEEN A RECENT AMALGAMATION OR SPLIT IT IS IMPORTANT TO ASCERTAIN EXACTLY WHAT THE LIABILITIES OF THE NEW AND OLD BUSINESSES ARE.

PROFESSIONAL INDEMNITY INSURANCE 5 NEGLIGENCE BY EMPLOYEES OF THE INSURED OR EMPLOYEES OF PREDECESSORS IN BUSINESS IS ALSO COVERED. MISTAKES BY EMPLOYEES ARE THE MOST FREQUENT CAUSE OF CLAIMS UNDER A P.I. POLICY; THE P.I. POLICY ALSO PROTECTS THE INSURED AGAINST ANY LIABILITY HE MAY INCUR ARISING OUT OF THE USE OR EMPLOYMENT OF AGENTS; THIS SUBJECT IS MAINLY A PUBLIC LIABILITY COVER AND WILL BE COVERED MORE EXTENSIVELY BY THE PUBLIC LIABILITY COURSE, WE THEREFORE, DO NOT INTEND TO GO FURTHER INTO THIS SUBJECT.

BUILDING DEFECTS INSURANCE 1 OTHERWISE KNOWN OVERSEAS AS DECENNIAL LIABILITY; IT HAS ITS ORIGINS IN NAPOLEONIC LAW; IT ONCE AGAIN GAINED POPULARITY AFTER THE FIRST WORLD WAR WHEN CONSIDERABLE CONSTRUCTION WAS TAKING PLACE IN EUROPE; THE POLICY COVERS INHERENT DEFECTS IN BUILDING STRUCTURES WHICH ONLY BECOME MANIFEST AFTER THE COMPLETION OF CONSTRUCTION, WHERE THIS THREATENS THE STABILITY OF THE STRUCTURE DUE TO DESIGN PLAN SPECIFICATION MATERIALS OR WORKMANSHIP LANDSLIP SUBSIDENCE OR HEAVE IS ALSO COVERED; THE COVER IS BASED ON THE DESIGN PLAN AND SPECIFICATION BEING FULLY DIVULGED TO INSURERS FOR APPROVAL BY THEIR CONSULTANTS AND THAT GEOTECHNIC AND HYDROLOGY TESTS ARE CARRIED OUT ON THE SITE AND THE RESULTS ARE GIVEN TO INSURERS FOR APPROVAL COVER MUST BE APPLIED FOR BEFORE COMMENCEMENT

BUILDING DEFECTS INSURANCE 2 THE PRIMARY COVER EXCLUDES WATERPROOFING OF THE BUILDING ENVELOPE, HOWEVER, THIS DOES NOT EXCLUDE DAMAGE TO THE STRUCTURE AS A CONSEQUENCE OF FAULTY WEATHER PROOFING; INSURERS CONSULTANTS MUST BE GIVEN ACCESS TO SITE THROUGHOUT THE CONSTRUCTION PERIOD; AFTER PRACTICAL COMPLETION A FURTHER INSPECTION OF THE ASPECTS THAT REQUIRED RECTIFICATION OR ATTENTION, ONCE SATISFACTORY COMPLETION HAS OCCURRED, BUILDING DEFECTS COVER CAN BE CONFIRMED; COVER GENERALLY EXCLUDES FIRE AND ALLIED PERILS, DAMAGE DUE TO ALTERATIONS, MODIFICATIONS OR EXTENSIONS INADEQUATE MAINTENANCE OR WHERE THE DESIGN LOAD HAS BEEN EXCEEDED; THIS COVER DOES NOT TAKE PRECEDENCE TO THE MAINTENANCE COVER AFFORDED BY THE CONSTRUCTION POLICY.

CONSEQUENTIAL LOSS DUE TO CONSTRUCTION ACCIDENTS THERE ARE A VARIETY OF CONSEQUENTIAL LOSS COVERS THAT MAY BE TRIGGERED BY CONSTRUCTION RISKS, BOTH THE EMPLOYER AND THE CONTRACTOR CAN BE EXPOSED TO LOSSES AS A RESULT OF CONSTRUCTION ACCIDENTS; THE COVERS ENVISAGED ARE: INCREASED COST OF WORKING CONTRACTORS, ADVANCE LOSS OF RENT EMPLOYERS AND DEVELOPERS, ADVANCE LOSS OF INTEREST EMPLOYERS AND DEVELOPERS, ADVANCE PROFITS/DELAYED START UP.- EMPLOYERS WE WILL EXAMINE EACH OF THESE INDIVIDUALLY

INCREASED COST OF WORKING ACCIDENTS ON SITE CAN CAUSE DELAYS IN COMPLETION OR EVEN IN A WORST CASE SCENARIO THE TOTAL LOSS OF CONSTRUCTED WORKS, SAY BY FIRE OR FLOOD ETC. ACCORDINGLY THE CONTRACTOR MAY BE AT A LOSS DUE TO HAVING TO CONTINUE TO REMUNERATE WORKERS AND PAY CONTINUING HIRE CHARGES FOR PLANT AND MACHINERY DAMAGED IN THE EVENT. THE CONTRACTOR WILL AS A RESULT BE OUT OF POCKET AS HE WILL NOT BE ABLE TO RECOUP THE INCREASED COSTS. COVER FOR SUCH LOSSES IS AVAILABLE IN THE MARKET BUT SUBJECT TO A TIME EXCLUSION AND INDEMNITY PERIOD, THE PREMIUM CHARGE IS NOT CHEAP.

ADVANCE LOSS OF RENT OR INTEREST THIS COVER IS MAINLY DIRECTED AT EMPLOYERS, BEING PROPERTY OWNERS OR DEVELOPERS, WHO MAY SUFFER RENT LOSSES DUE TO DELAYED OR NON COMPLETION OF THE WORKS. PART OF THE FEASABILITY STUDY BEFORE ENTERING INTO ANY CONTRACT FOR CONSTRUCTION, OR EVEN PURCHASING THE LAND, THE EMPLOYER EVALUATES THE OVERALL COST TO HIM AND AT WHAT POINT HE WILL START TO RECEIVE EARNINGS FROM HIS INVESTMENT. IT MUST BE REMEMBERED THAT HE IS EITHER USING HIS OWNN FINANCE OR HE IS TAKING OUT LOANS TO COVER THE COST OF DEVELOPMENT IN EITHER CASE HE IS EITHER LOSING INTEREST ON VESTED CAPITAL OR HE IS PAYING INTEREST ON THE LOAN. THE CONSTRUCTION PERIOD IS THUS VITAL TO HIS POTENTIAL COST

ADVANCE PROFITS OR DELAYED START-UP - 1 THIS COVER IS ALLIGNED MAINLY TO PRODUCTION PROCESSES. INVESTORS WHO PUT MONEY INTO A VENTURE DO SO FOR THE PURPOSE OF INCREASING THEIR WEALTH THROUGH SUCH INVESTMENT, ACCORDINGLY, THEY EXPECT THE EARNINGS OF THE VENTURE TO COMMENCE ON SCHEDULE; THE VENTURE MAY BE AN INDUSTRIAL MANUFACTURING PROCESS, MINING OR A CHEMICAL OR PETRO-CHENICAL FACILITY; IRRESPECTIVE OF THE NATURE OF THE VENTURE, WHEN THE OPERATIONS RUN LATE, THIS BRINGS ABOUT AN UNEXPECTED LOSS TO THE INVESTOR. HAPPILY, HE CAN INSURE AGAINST THIS EVENTUALITY UNDER AN ADVANCE PROFITS POLICY; THE ADVANCE PROFITS POLICY IS ONLY TRIGGERED BY AN INDEMNIFIABLE EVENT UNDER THE CONSTRUCTION POLICY.

ADVANCE PROFITS OR DELAYED START-UP - 2 THE SUM INSURED UNDER THIS POLICY IS A FIXED AMOUNT BASED ON THE EXPECTED EARNINGS OF THE BUSINESS DURING THE PERIOD OF INDEMNITY SAY 12 MONTHS, THE COVER IS SUBJECT TO AVERAGE. THERE IS, HOWEVER, A DEDUCTIBLE APPLICABLE TO THE INDEMNITY, THIS IS A TIME EXCLUSION WHICH IS USUALLY QUITE LENGTHY FOR COMPLEX PRODUCTION PROCESSES AND MINING, THIS COULD EXTEND TO THREE MONTHS, MOST STANDARD TRIED AND TESTED PROCESSES WOULD HAVE A 1 TO 3 WEEK EXCLUSION PERIOD, BUT NEVER LESS THAN 3 DAYS. SOME PROCESSES SUCH AS PETRO-CHEMICAL RISKS HAVE AN EXCLUSION OF COVER DURING THE FIRST 7 DAYS OF TESTING, IN OTHER WORDS ANY ACCIDENT OR FAILURE DURING THE FIRST 7 OPERATING DAYS, WHILE COVERED UNDER THE WORKS POLICY WOULD NOT QUALIFY FOR INDEMNITY UNDER THE ADVANCE PROFITS POLICY.

ADVANCE PROFITS OR DELAYED START-UP - 3 CLEARLY, THE COVER MUST BE BASED ON A REALISTIC COMPLETION DATE (DATE ON WHICH COMMERCIAL PRODUCTION IS EXPECTED TO COMMENCE). THE CLIENT HAS AN OBLIGATION TO KEEP THE INSURER INFORMED ON OCCURRENCES AND EVENTS THAT MAY HAPPEN OR OCCUR THAT WOULD DELAY OR RETRACT THE COMPLETION DATE, THUS AFFECTING THE COVER UNDER THE POLICY. THE INSURER IS GIVEN ACCESS TO THE CONSTRUCTION SITE AT ANY REASONABLE TIME TO ENSURE THE WORK IS BEING UNDERTAKEN UNDER GOOD ENGINEERING PRACTICES AND TO QUANTIFY THE COMPLETION DATES OF INDIVIDUAL COMPONENTS AND THE INTEGRITY OF THE PROJECT AS A WHOLE. THE INSURER ALSO HAS THE RIGHT TO TAKE OVER AND CONTROL ANY REPAIR OR REPLACEMENT PROCEDURE TO ENSURE THAT THE WORK IS UNDERTAKEN EXPEDITIOUSLY AND TO PROPER STANDARDS OF ENGINEERING EXCELLENCE.

BONDS - 1 CONTRACTORS ARE INVARIABLY REQUIRED TO PROVIDE CERTAIN TYPES OF BOND OR GUARANTEE. THE PROVIDERS OF THESE BONDS OR GUARANTEES ARE EITHER A BANK OR INSURANCE COMPANY. THE MOST USUAL BONDS ARE: PERFORMANCE BONDS: THIS IS ONE OF THE MOST IMPORTANT BONDS GIVEN BY A CONTRACTOR, IT IS FURNISHED BY THE CONTRACTOR BEFORE THE START OF THE CONTRACT. ITS SOLE PURPOSE IS TO PROTECT THE EMPLOYER AGAINST BREECH OF CONTRACT BY THE CONTRACTOR; BID OR TENDER BOND: THIS BOND IS SUBMITTED BY THE CONTRACTOR WITH HIS BID OR TENDER, THUS SHOWING THE EMPLOYER THAT HIS BID IS REASONABLE AND IF ACCEPTED THE CONTRACTOR WILL SIGN A CONTRACT TO PERFORM THE WORK INCLUDING ANY BOND REQUIREMENTS. THE BOND IS FORFEITED IN FAVOUR OF THE EMPLOYER IF THE CONTRACTOR FAILS TO PERFORM THE WORKS SPECIFIED IN THE TENDER

CAUSES OF LOSS OR DAMAGE It can take months from the date of acquiring a green fields site until construction work commences. In many cases, existing buildings on the site have to be demolished before construction work can begin. The construction period for major civil engineering projects, such as freeways and dams, is often between three and five years, whereas the construction and commissioning of a power station can take up to 8/10 years. The following paragraphs outline briefly the nature of each process, each of which has its own potential hazards

CAUSES OF LOSS OR DAMAGE DEMOLITION This can take many forms, depending on the nature of the building, its location, and proximity to busy thoroughfares. In some cases, some part of the structure may be left standing, to be incorporated into the new works. This may need special consideration by the contract works underwriter, in view of the usual exclusion of existing structures. Surrey House, M & F Centre Facades (National Monuments) If the location is remote, the job may be done quickly by the use of explosives. The operatives must be experienced in the use of explosives, and all safety regulations must be complied with. In most cases, the use of explosives, or even mechanical means, is not practical or safe because of the presence of the general public. If the site is in a derelict area, a crane jib and ball can be used to pull down walls, or an earth moving machine with hawser attached can be employed.

CAUSES OF LOSS OR DAMAGE DEMOLITION CONTINUED In recent years, it has become fairly common practice to demolish high rise buildings using the implosion method. Highly specialised skills are required, and underwriters will tend to focus on the track record of the demolition contractors, and any deviation from the techniques successfully used by them in the past. As this type of operation normally takes place in heavily built-up areas, the contractor needs to obtain the full co- operation of the authorities and traffic police to warn and safeguard the occupants of surrounding buildings and the general public. In addition, steps are generally necessary to provide physical protections for the buildings closest to the contract site. (Matla Chimney Stack)

CAUSES OF LOSS OR DAMAGE DEMOLITION CONTINUED Underwriters need to protect their interests by employing a suitably qualified structural engineer to evaluate the methods and techniques to be used by the demolition contractor. Such engineers, in conjunction with the demolition contractors engineer, should undertake a survey of buildings in the explosion zone of the demolition to establish existing cracks and other defects, photographs should be taken as evidence. Protective covers should be placed over air conditioning intakes of adjacent buildings (within the dust zone). (Customs House, Johannesburg)

CAUSES OF LOSS OR DAMAGE GROUND WORKS Ground work differs from all other construction work in that very little is constructed. The insurer must remember that the prime purpose of the work is the excavation of material to form spaces and, if they are refilled by accident, considerable expenditure may be necessary to re-excavate the space. The work involved may be sub-divided into: earth moving such as cut and fill operations or fill only operations; mass excavation can form part of a construction contract, or be let as a separate contract, or as a main sub-contract where the sub-contractor may or may not be required to arrange his own insurance. trenching or water diversionary works including canalising of waterways; tunnelling and shaft sinking which may embrace underground development works); piling. Let us look at each process separately.

CAUSES OF LOSS OR DAMAGE EARTHMOVING Earth moving normally forms part of a major project such as road building or may be the preliminary to the construction of a large industrial complex or power plant. Earth moving will also form a large part of the work involved in the construction of an earth embankment dam. In most African countries, the major risk in this type of work is the removal of construction material by heavy rainfall or flooding, particularly in the case of large road projects, where the logistics and cost of replacing the material can be time consuming and costly and involve considerable labour and plant usage. NATAL NORTH COAST HOUSING TERRACES WASHED AWAY The cost of salvaging and repairing large and expensive items of plant that have been flooded can also result in substantial claims, usually under a plant insurance policy. Koeberg scrapers

CAUSES OF LOSS OR DAMAGE MASS EXCAVATION Mass excavation is normally associated with foundation works or the construction of basements utilising methods (including dewatering) already described. In all cases, except shallow excavations where the soil conditions allow the use of a reasonably unsupported batter (slope), some support to the sides of the excavation will be necessary. Concrete diaphragm wall constructions in a bentonite slurry, or walls of close concrete piling constructed before excavation begins should be self supporting. In the case of sheet steel pile cofferdams, within which excavation is to take place, there is always the risk of some instability. This may be caused by not driving the piling to a sufficient depth so that the toe is uncovered during excavation, by the flow of ground water scouring beneath the toe, or by ground or ground water pressure where no walling beams and cross strutting have been employed in a single skin cofferdam.

REMOVAL OF SUPPORT IF LATERAL (SIDEWAYS) SUPPORT IS REMOVED, THE BUILDING WILL SLIDE INTO EXCAVATION, HOWEVER, IF VERTICAL SUPPORT IS REMOVED THEN THE BUILDING WILL COLLAPSE INTO THE EXCAVATION. REMOVAL OF LATERAL SUPPORT GROUND AND BUILDING WILL COLLAPSE OR SLIDE EXCAVATION REMOVAL OF VERTICAL SUPPORT GROUND WILL COLLAPSE INTO EXCAVATION WITH BUILDING THUS WE SHOULD TALK ABOUT REMOVAL OF SUPPORT AND NOT REMOVAL OF LATERAL SUPPORT

CAUSES OF LOSS OR DAMAGE MASS EXCAVATION Whatever the method of supporting the sides of the excavation, however, there is always the risk of inundation due to heavy rain or floodwater, or the complete breakdown of the dewatering pumps. Deep excavations may require complex internal strutting and other support work resulting in a considerable restriction of the operational area. As a consequence, there is a distinct possibility of damage to these temporary works arising from the use of constructional plant or during further excavation. Such damage could be costly to repair by reason of additional expense in the avoidance of further damage in the course of restoration or by the debris-removal operations being extensive. A careful assessment should be made of the total value of the constructional plant which may be in use within the excavation at any one time. LUDERITZ HARBOUR WAVE SWELLS +5M DESIGNED FOR SWELLS OF -3M SHEET PILES LOOSENED AND COLLAPSED

CAUSES OF LOSS OR DAMAGE TRENCHING As with mass excavation, the main hazards with trenching are collapse of the sides or inundation of the trench. Frequently, trench collapses are caused by the complete absence of shoring and strutting to the trench sides because of the firm cohesive nature of the soil in which the trench is excavated. However, these soils are liable in abnormal weather conditions to become unstable and collapse. Trenches may also become filled with water, snow, sand, dust, mud and other detritus requiring careful re-excavation or dewatering. In view of the seriousness of the hazard in such work, the insurers may wish to impose a warranty as to the maximum length of trench exposed at anyone time. LAW REQUIRES TRENCH +1M TOBE BRACED

CAUSES OF LOSS OR DAMAGE SHAFT SINKING Trial bore holes along the route will only give a partial indication of the hazards to be met. More accurate hydrology and geological information will be gleaned by radial drilling (probing ahead of the working face), thus identifying the exact nature of ground conditions and expected water conditions before driving the next stage of the excavation. Although there are always inherent risks in the use of explosives and working below ground level, the results of any serious difficulties are likely to be more expensive to the contractor in terms of delay and remedial works than to the insurer in terms of a claim. The insurer will, however, need to consider such delay if his policy should contain a consequential loss section (advance profits or delayed start-up) The presence of ground water or water bearing strata may be dealt with either by the method of freezing the surrounding areas using refrigeration pipes, or by curtain grouting in advance of tunnelling operations Curtain grouting, if effectively carried out, has the advantage of being a permanent protection, whereas any breakdown in the refrigeration process could result in the flooding of the tunnel. It is normal for the tunnel lining to be constructed as the tunnelling proceeds and there is always the possibility of damage to this lining if inadvertently too large an explosive charge is used.

CAUSES OF LOSS OR DAMAGE SHAFT SINKING Shaft-sinking is generally associated with mining operations, which, because of the vast depths to which they now mine mainly gold (up to and in excess of 3 kilometres, there are now plans to sink shafts to 4 kilometres) requiring highly specialised skills. The development of a mine can include vertical and incline shafts as well as horizontal and incline tunnels. These shafts are generally sunk from the surface, however because of the great depths to which mining operations are now carried out it is usually more advisable to develop sub-vertical or sub-incline shafts at a point considerably below ground level to minimise the drop from surface to the shaft bottom, thus eliminating stretching the rope and causing bounce.

CAUSES OF LOSS OR DAMAGE SHAFT SINKING Shafts are not only excavated by drilling, blasting and grubbing but can also be excavated by raise-boring, which also has its dangers. Experience has shown that the most effective size of a raise-bore is 6 metres (diameter) or less. This type of operation requires very specific geologic investigation as well as hydrology identification as the work will be undertaken in virgin ground with little or no knowledge of the ground conditions.

CAUSES OF LOSS OR DAMAGE SHAFT SINKING CONTINUED There are certain terms and exceptions usual to this type of risk due to the nature of the unknowns of the geology and hydrology of the area. For example, the Western area of Gauteng is mainly a dolomite area, which acts as a sponge full of water due to all the voids, cracks and fissures. It is quite amazing when boring in to this rock as to the amount of water that can flow. Accordingly, the underwriter must be aware of the risks to limit or exclude if he is to write risks in this area. In a like manner there are many other areas in South Africa that have peculiar rock strata that need to be addressed, the risks become more extensive when underwriters expand their horizons into Africa, where the geological and hydrology conditions are unknown. SOUTH DEEP SHAFT FILLED TO ABOUT 250/300M IN LESS THAN AN HOUR. GROUTING & FITTING AND REMOVING PLUG

CAUSES OF LOSS OR DAMAGE SHAFT SINKING CONTINUED The usual conditions to be included in insurance policies covering shaft sinking are: (a)a requirement for radial drilling (probing) ahead of the working face; (b)excluding the pumping of water or damage due to the quantity of water in-flow exceeding that which was established during investigations by test-boring in the area of the excavation; (c)the cost associated with fitting and removing a concrete plug to stem the flow or ingress of water into the excavation works; (South Deep Shaft) (d)to exclude the cost of restoring the designed diameter (neat line) of the shaft due to overbreak (a condition caused by excessive use of explosives or inappropriate drilling of blast holes); (e)restoring collapse exceeding 1 or more metres (at the discretion of the underwriter) from the tangent of the neat lines of the excavation.

CAUSES OF LOSS OR DAMAGE SHAFT SINKING CONTINUED It is usual during shaft sinking for unstable rock areas to be reinforced by rock bolts or cable rock ties, sometimes steel mesh is fixed to the bolts or ties, which is then gunited to establish a firm surface, nevertheless, collapses still occur. The cost of reinstating the collapsed material can be fairly expensive and underwriters may wish to limit their financial exposure. Accordingly, it is not unusual for an exclusion to be included in the policy limiting the cost of reinstating the collapsed material to the amount of fill required to reinstate the length of the rock bolt or rock tie.

CAUSES OF LOSS OR DAMAGE SHAFT SINKING CONTINUED Shaft sinking is a highly specialised activity and the underwriter who thinks he has the competency to know it all is fooling no one but himself. It is imperative, if one wishes to participate in shaft sinking Insurance, that the underwriter employs an experienced mining consultant to evaluate geotechnical and hydrology investigation reports and then the excavation programme and methodology of work proposals. ORIGINAL POSITION OF SOUTH DEEP SHAFT COLLAPSE AND RESITING

CAUSES OF LOSS OR DAMAGE SHAFT SINKING CONTINUED A tunneling project basically involves the creation of a self-supporting or artificially supported space or void within a section of a ground mass, which prior to excavation was in a stabilised state of local equilibrium. The stresses and pressures disturbed by the excavation will be transferred to the tunnel surfaces. If these stresses or pressures are not effectively relieved or checked, it is inevitable that there will be problems for the contractor and consequently losses for the insurer. Exposure to air, and possibly water, may initiate chemical and other weathering processes not previously present, which lining, grouting and other work must take into account.

RISK ASSESSMENT SHAFT SINKING HAZARDS - 1 Although Shaft Sinking has been practiced for more than 100 years, despite considerable development of scientifically based methods of site investigation and design, it remains substantially an art. The success of any shaft sinking project will depend largely upon the accuracy with which the site investigations can predict ground conditions, the adequacy of the consulting engineer's planning and design to meet the actual conditions, and the preparedness and ability of the contractor to deal with the hazards encountered.

RISK ASSESSMENT SHAFT SINKING HAZARDS - 2 The prediction of ground conditions is based on careful geological mapping from the surface, and subsurface exploration by boreholes and, in the case of incline shafts by excavating adits at selected points along the shaft route carried out during the planning of the project. Where hazardous ground is predicted, it is now common practice for more detailed exploration to be carried out during construction by probing ahead of the tunnel face with long boreholes. The geological features of the site are among the most important factors in assessing the risk.

RISK ASSESSMENT SHAFT SINKING HAZARDS - 3 A shaft sinking project basically involves the creation of a self-supporting or artificially supported space or void within a section of a ground mass, which prior to excavation was in a stabilised state of local equilibrium. The stresses and pressures disturbed by the excavation will be transferred to the shaft surfaces. If these stresses or pressures are not effectively relieved or checked, it is inevitable that there will be problems for the contractor and consequently losses for the insurer. Exposure to air, and possibly water, may initiate chemical and other weathering processes not previously present, which lining, grouting and other work must take into account. The permeability of the ground mass, the water table and variations brought about by temporary surface conditions should be investigated.

RISK ASSESSMENT SHAFT SINKING HAZARDS - 4 However, the contractor can rarely be entirely confident as to the conditions expected as local weathered zones, faults, fissures, dykes, discontinuities, aquifers, voids, made up ground and even past mine workings can seriously upset predictions and, with conditions very different from those of the surrounding rock mass, present unexpected hazards of inundations. Especially when compressed air is used, the risks of fire and explosion can be very serious in all shafts

RISK ASSESSMENT SHAFT SINKING HAZARDS - 5 The hazards to be expected in shaft sinking are: rockfalls and rockbursts; collapse of tunnel sides; inrush of water; inrush of soil or broken rock; fire and explosion; heave or subsidence of ground surface. In shaft sinking, falls are usually due to broken or crushed rock, often associated with faults. In certain rocks containing expansive clay minerals, enormous pressures, particularly at great depth, can be expected on the shaft sides causing collapse. Below the water table, heavy flows of water and loose materials are usually associated with faulted or broken rock or with cavernous rock such as limestone. Explosive gases are often found in coal-bearing shales. Toxic gases can occur in volcanic rocks.

RISK ASSESSMENT SHAFT SINKING HAZARDS - 6 The difficulties of dealing with flooding are greatly increased if the water is encountered at the considerable depths to which many shafts are sunk. Insurers must make appropriate enquiries about provisions for pumping and grouting. The considerable vertical distances involved in this type of shaft sinking can greatly increase the risk of damage to constructional plant, as well as to the works. Any equipment that may be accidentally dropped could easily sustain and inflict considerable damage. Much heavy equipment is used in shaft sinking, for example, the kibbles used for removing rock to the surface may be carrying 15 tonnes or so. With some mines, once the initial sink and shaft collar have been completed and the headgear structure has been built, a sophisticated system for winding can be installed and this usually incorporates many elaborate safety precautions.

PILED FOUNDATIONS PILE CAP WEAK GROUND PILES CONCRETE OR STEEL BEARING STRATUM

PILED FOUNDATIONS Where the maximum bearing strength of the ground is less than the applied load, subsidence will occur. Some means must therefore be adopted to increase the bearing capacity of the ground and the normal method is to use bearing piles. Bearing piles, as distinct from sheet piles, are nothing more than columns under the ground reaching down to a firm stratum or if this is too deep, relying for their support on the friction grip of the ground (otherwise known as friction piles). The methods of piling and types of bearing pile used are numerous, embracing a number of proprietary systems. However, basically they may be divided into two main types: Driven steel or concrete Bored - concrete

PILED FOUNDATIONS DRIVEN PILES Driven piles or displacement piles as they are sometimes known, are defined as those which displace the ground through which they are being driven. Driven steel piles take the form of steel beams (H piles) or tubes or box sections driven into the ground, the tubes and box sections are usually filled with concrete. H section Steel pile Typical box section steel pile

PILED FOUNDATIONS DRIVEN PILES CONTINUED Alternatively the piles may be made of pre-cast concrete, often pre-stressed, suitably strengthened to withstand the blows from the driving hammer. Piles formed by driving pre-cast hollow concrete sections or steel tubes, (either extracted later or left in situ) in which concrete is then used to make up the shaft, these are known as driven cast-in-situ piles. Pile driving equipment consists of a piling frame, which has the function of guiding the pile at its correct alignment from first pitching in position to its final penetration, a driving hammer and a multi-drum winch for handling the hammer, lifting a pile and also to operate the travelling, slewing and raking gear on the rig. There are many designs of custom-made driving rigs available.

PILED FOUNDATIONS DRIVEN PILES CONTINUED Often piles are driven by means of purpose adapted site cranes on which are mounted leaders, which are the essential parts of a piling frame consisting of stiff steel beams usually of channel, box or tubular section. BORED PILES These are formed by boring a hole in the ground and, if necessary, inserting a steel lining (which is often retracted later) to prevent the sides from collapsing. After boring the hole, steel reinforcement is inserted and the hole filled with concrete

PILED FOUNDATIONS BORED PILES continued Power driven auger rotary drills are suitable for installing bored piles in clay soils and a wide range of machines are available. For drilling through sands, gravels and loose rock formations, the pile boreholes may require continuous support by means of a casing which is driven to the required depth into the ground and the material within the casing is removed by grabbing or auger drilling tools. Small diameter piles of up to 600mm diameter requiring continuous support by lining tubes (casing) may be bored using simple tripod rigs. The leading tube has a sharpened cutting edge and is driven down under the impact of a heavy drill stem. In clays, the soil which jams inside the tube is prised out by spade when the cutter is raised to the surface; in ground lacking in cohesion the cutter is provided with a flap valve to retain excavated material which is emptied at ground level merely by releasing the flap.

PILED FOUNDATIONS PILE CAPS The purpose of a pile cap is to spread the load imposed upon it onto a group of piles so that, as far as possible, the load is shared equally between the piles. A pile cap also accommodates deviations (within specified tolerances) from the intended position of piles and by rigidly connecting all the piles in one group by a massive block of concrete, the ill-effects of one or more less than fully effective piles are overcome by redistributing the loads. A piling contractors work is usually confined to the installation of the piles themselves. Cutting them down to level and constructing pile caps is normally undertaken by the main contractor.

PILED FOUNDATIONS PILE CAPS CONTINUED Pile caps are constructed in many shapes and sizes, some large and spread over a number of piles e.g. in heavy foundations for reaction vessels in process plants or boiler and generating equipment in power stations, and others quite small supporting single light duty columns or small items of machinery. The minimum number of small diameter piles permitted on an isolated pile cap is three; caps for single piles must be interconnected by ground beams in two directions and for twin piles by ground beams at right angles to the common axis of the pair.
