Construction of Dam, Reservoir, Pipe Laying and Other Minor Works for Rural Water Project

1 PROJECT BACKGROUND & PURPOSE


The Water Authority of Fiji is currently in the process of extending its water reticulation system tomeet the demands of the people of Fiji and at the same time, provide Clean Water for aBetter Life

This year, all projects under the rural scheme will be outsourced for the first time. All projectswere selected based on the locality and accessibility to the dam and reservoir site. High waterdemand & damages in the existing pipeline has resulted in frequent disruption of supply tovillagers daily. Therefore the villagers have requested WAF to investigate alternative ormethods to eliminate the issue of water supply to the villagers.

These projects will include the supply of materials and the construction of new village dam atthe proposed new water source, installation of Ferro Cement tanks and the installation of pipesto meet its daily water requirements. Hence, prior to the construction of the new watersystems, the villagers will be utilising the existing system for daily consumption. There would alsobe excavation works and material carting done by villagers to respective sites of workrequired, however, The Contractors will be given the obligation to pay off villagers forexcavation works based on the lengths of pipe laid per day and materials carting will be partof the village contribution under the Rural Policy, Similarly, the villagers will be responsible forproviding accommodation to the contractors within the period of contract. All payments tothe villagers will be in accordance to the amount agreed by the Employer.

The Water Authority of Fiji (WAF) seeks proposals from competent and suitably qualifiedcontractors to conduct this project, pursuant to the requirements stipulated under Scope ofWorks, as per the designs by WAF. All materials will be supplied by Water Authority of Fiji to thecontractors and therefore the contractors are to only bid for the construction works and notthe supply of materials.

I.] INTRODUCTIONThe circular Ferrocement water tanks being made in Fiji by the Water Authority of Fiji are taken fromdesigns and construction procedures set out in a manual by S.B.Watt, Ferrocement Water Tanks and TheirConstruction, London, 1978The basic features of these tanks are: The tanks are built on site on top of a minimum 150mm circular concrete foundation using curvedcorrugated roofing iron formwork Galvanized Chainlink fencing is used as the major reinforcement with binding wire and No.8Galvanized Wire as the ring reinforcement The walls of the tanks are on the average 75mm thick made from clean sifted sand and cementmortar applied to the inside and outside of the galvanized iron reinforcement All tanks have roofs made of the same reinforced mortar averaging 75mm in thickness. A centre post (100 – 150mm) is used in all tanks All tanks are provided with a manhole, washout, overflow, air vent, and inlet and outlet pipeworksAll materials, with the exception of local sands, timbers, and gravel where available, are supplied by WaterAuthority of Fiji through the Self – Help Rural Water Supply Subsidy Program. Skilled workmen along withlocal village labour construct the tanks on siteThe following manual sets out the step by step process for construction of these tanks. Photos used in thismanual show the construction of both the 2,500 gallon (11,365 litres) and 6,600 gallon (30,004 litres)tanks. Table 1 shows the range of tank sizes possibly using four standard formworks but with varyingheights

II.] ASSEMBLING TANK FORMWORKThe tank formwork is fabricated form the following materials (quantities upon tank size):1. Zincalume corrugated roofing iron, 24gauge, 3’ (0.91m) width2. Steel Angle Line (37mm x 37mm x 3mm thick)3. Ø9mm x 75mm long Galvanized Bolt & Nut4. Seam Bolts (37mm x 3mm)5. Rough Timber (100mm x 50mm)The Roofing Iron is cold rolled to the set tank diameter by either the Ministry of Works Central Division’sBoiler Shop, if possible, or an outside company with a corrugated iron rolling machine. It must beremembered that a 50mm wooden timber wedge must fit between each rolled iron

The Steel Angle Line are to be bolted on to the inside face at the ends of each rolled corrugated iron sheet.The angle irons will help to hold together sets of roofing sheets which must be stacked on top of each otherto get the proper tank height. The stacking of curved roofing sheets should be done so that one corrugationon each sheet is overlapped and so the outside face of the sheets is smooth

LIKE THIS: INSIDE NOT LIKE THIS: INSIDE

Preferably, three (3mm) diameter holes should be drilled into each roofing sheet and supporting angleiron. Seam bolts are then used to hold the roofing sheets to the irons. The irons should be Rust Guardpainted prior to use.

6 | P a g e

The Timbers must be placed between each set of roofing sheets and corresponding angle irons. Thetimbers should be positioned before drilling so that the holes made by the corrugations on the outside ofthe forms are covered by the wood. This prevents mortar from entering these spaces and makingdisassembly difficult. Holes (9mm) must be drilled into the angle irons on the perpendicular face of theiron from the roofing sheets to hold the timber secure between the sheets. At least one hole should bedrilled per roofing sheet in the angle iron. When the timbers are positioned properly a wood drill can beused to make 9mm holes to match the pre-drilled holes on the angle irons

LabellingThe roofing sheets, angle irons and timbers should be labelled with paint to facilitate reassembly. Labellingshould look something like this:

7 | P a g e

ALTERNATIVE FORMWORKLess costly formwork can be made for Ferrocement tanks using sheet metal which is held together andsupported in a circular shape using bush poles and nails

More basic than this method is reinforcement and formwork made from bamboo. This method is describedin How to Build a Water Tank written and designed by Dr. Pauulu Kamarakafego

Square modular Ferrocement tanks can also be made using moulds and steel fibres mixed in with themortar. The panels made from these moulds can then be transported to the tank site and assembled. Themethod and design is described in a manual put out by the World Health Organization, Manual onCo ns truc ti on of Co ok Is land’s Modular Water Ta nks , Suva, October 1983

CONSTRUCTION MATERIALSThe quality of the construction materials is very important to the quality of the final product – the tankSand: Where possible local sands should be used. This sand must be washed and sifted. Beach sand canbe used as long as all salt is washed out with fresh water and sifted. River sands composed of silicaof moderately coarse grains are best. Black soapstone sands from rivers should be avoided sincethese sand grains tend to be very softGravel: All gravel used in the concrete foundation should be clean and free from organic debris. The gravelsize should be no larger than 18mmWater: All water used in mixing the concrete and plaster should be clean and free from salt and suspendedsiltReinforcing Mesh and Binding Wire: Wire and mesh used should be galvanized. The white powder whichoften forms on the, should be brushed off before use to create betterbonding with the mortar

9 | P a g e

III) CONSTRUCTION PROCEDURES FOR FERROCEMENT TANKFOUNDATION1. Choose a tank site which meets the following criteria. The tank site is: Away from large trees At least 3.6m (12ft) away from pit or water seal latrines Cleared of old rubbish pits, rotting tree stumps, and protruding rocks. The remaining holesshould be filled with sand and gravel Of firm base and away from steep erodible slopes and rain runoff paths2. A circular area, at least 300mm (1ft) greater than the tank diameter, must be cleared, excavateddown at least 150mm (6 inches) through the topsoil, and levelled. For larger tanks, over 10,000gallons, a 300mm x 300mm wall ring foundation should be excavated around the perimeter of thetank excavation. Likewise, a 300mm² base is needed for all columns to go inside the tank ofvolumes over 10,000 gallons.

3. Over the base of the levelled dirt floor a minimum of 50mm (2inches) layer of sand and/or gravelshould be laid.4. Pipe works for the tank outlet and washout must be laid in the dirt base. (Refer to tank drawings)5. Reinforcement for the floor and columns is then placed making sure that the reinforcement will becast into the middle of the poured concrete. Reinforcement should be either 12 x 7 ft steel meshwire fabric or ½” Deformed Mild Steel @ 200mm centres for the floor. Reinforcement for thecolumns should be 3 - ⅜” Deformed Mild Steel.6. A concrete mixture of 1:2:4 (cement: sand: gravel) by volume, is then mixed and poured into theearthen mould.7. Keep foundation moist until hardened. Formwork may be erected on the foundation when concretehas hardened.

10 | P a g e

ERECTING FORMWORK AND REINFORCEMENT1. To begin formwork assembly, first bolt wooden timbers to their two (2) corresponding angle irons.Then bolt the first (1st)ring of corresponding curved roofing sheets to the angle iron/timber/angleiron units. Complete by bolting successive rings of roofing iron on top of the first ring.

Picture showing tank formwork @ Nakawakawa, Bua (April 2012)2. Oil the outside face of the formwork with a light film of oil making sure that all corrugation groovesare coated.3. Wire netting is then wrapped around the formwork in a single thickness and tucked under theforms about 6 inches (150mm). In the 20,000 gallon tank, the chain link fencing is not tucked underthe forms but tied into the ½” steel starter bars which have been tied to the floor reinforcement andconcreted into the foundation. The netting or chain link fencing should be pulled tight. The ends ofthe netting or chain link should be overlapped with soft iron binding wire. A one foot (300mm)length of netting or chain link should extend above the intended height of the tank. When morethan one (1) wrap of netting or chain link is used to cover the formwork all edges should beoverlapped and vertical seams alternated around the tank.4. Binding wire or No.8 galvanized wire in the larger tanks is then wrapped around the formwork ontop of the netting and in each corrugation. There should be:

2 wraps of wire in each corrugation for the first ⅓ of the tank height 1 wrap of wire in each corrugation to the top 2 wraps of wire in the top corrugation

11 | P a g e

The ends of the wire should be overlapped at least ½ metre, pulled tight and tied securely. The wireshould not be tied like shown below by twisting a knot at the junction. This causes weakness in thewire.An easy way to tighten the wires is by making the junction of the wires occur at one of theformwork timbers. A nail can be driven into the timber and used as a pivot point for overlappingand pulling the wire tight. These wire junctions should be alternated for each corrugation wrap.When using No.8 wire, bolt cutters are needed to cut the wire. In the 20,000 gallon tank a specialwire pulling tool can be used to tighten the wire around the chain link fencing.

5. To make the reinforcement ready for plastering: All protruding wires, knots and overlapping must be made as flat as possible to theformwork. All nails used to tie in the circular wire wraps must be pulled out. The junction between the concrete foundation and the base of the formwork just be sweptand cleared of any dirt particles to guarantee a proper bondage between the wall plasterand concrete base.PLASTERINGBefore beginning the plastering it is recommended to erect a sun shelter above the tank either witha tarpaulin or with bush timber and roofing iron.

12 | P a g e

FIRST LAYER1. A plaster mix of 1:3 (cement: sand) is used for first outside layer. Just enough water to make a fairlydry mix is needed.It is very important to control the amount of water added to this first mix. A dryer mixcreates a stronger wall.Concrete mixers are not encouraged because they tend to manage only wet mixes.2. Into this water a water proofing cement additive should be mixed (either Pudlo or Sika product).The amount added should be according to the instructions on the container.3. The plaster mix for the first layer should be dry enough so that the plaster can be wedged into themesh wire without sloughing off. It should be wet enough so that the mix can be spread onto thereinforcing wires. The first layer should be thick enough to just cover the mesh and circular wireswith impression still slump off.4. Following completion of the first layer and when the plaster is a bit hardened, scratch marks shouldbe made on the layer so that the second plaster coat will stick properly.5. The tank walls should then be covered with plastic to keep the plaster moist and promote propercuring of the mortar walls until the second layer.6. If the complete first coat cannot be finished in one day the plaster should be brushed with a wirebrush and coated with cement slurry to give a strong bond before application of fresh plaster.7. Plaster which drops off the tank during application can be reused in that same layer as long as nostones or dirt has been mixed into it.

13 | P a g e

CURINGAfter the mortar has been applied to the tank walls it should be covered with plastic or wet sacking. Effortsshould be made to keep the walls moist even if this means watering down the walls every morning andevening. Quick loss of water from the mortar leads to shrinkage cracks and tank failure. The tank wallsshould be cured in this way throughout the duration of the tank’s constructionSECOND LAYER1. As soon as the first mortar layer has hardened sufficiently, slurry of cement and water can bebrushed onto the mortar. This acts as a plaster adhesive.2. The second plaster coat can then be applied. The mix should be moister than the first and beapplied to approximately 1cm thickness just to cover the first layer.3. When the plaster is a bit hardened a wooden floater can be used to smooth the outside layer and toadd a cosmetic finishing touch to the tank.4. The mortar should then be covered with plastic to keep the walls moist.

Plastering works for Nasau Ferro Tank, Navakasiga, Bua (April 2012)GETTING IN AND OUT OF TANKOnce the plaster has been applied there should be nothing leaning on the walls. To get in and out ofthe tank it is best to construct a bush timber, two (2) sided ladder.DISASSEMBLING TANK FORMWORKThe formwork can be taken down after 48 hours but it is safer and easier to plan to leave theformwork on over a weekend. To disassembly the formwork unscrew the timber to angle iron boltsand pry off the timber. The roofing irons can then be stripped off after unscrewing the seam boltsholding the roofing sheets to the angle irons.

INSIDE PLASTER LAYERSThe inside of the tank is plastered with mortar to fill up the corrugations. This coat is made roughand brushed with a slury mixture of water and cemestic so that the second coat will adhere.When the first coat has hardened sufficiently the second plaster coat is applied just to smooth outthe first coat and cover reinforcement wires properly.

FLOORWire mesh is tied into the underlapping wire from the walls and spread out to cover the entirefloor area of the tank. Over this is applied a 40 – 50mm layer of the mortar. It is very important tomake a coving between the walls and floor of a thickness, 75 – 100mm. The mortar is applied insuch a manner as to create a general slope towards the tank washout. The coving helps to seal thefloor/wall joint as well as strengthen this lower part of the wall where a concentration of waterpressure stresses occurs.To both the inside and outside walls of the tank, cement slurry (cement and water) should be appliedwhich helps to seal the tank.

6,600 Gallon Ferrocement Tank @ Nasau, Navakasiga, Bua New Tank @ Qoma Village, TailevuROOF When the tank floor is sufficiently hardened, formwork for the tank roof can be erected. Theformwork timbers must sit at least 25cm below the top mortar edge of the tank. Over the formworkis stretched wire mesh which is tied into the overlapping mesh from the walls. Two layers of mesh(if of the same gauge as the wall mesh) should be used on the roof. Alternatively, a heavier gaugemesh can be used on the roof. A 50 – 75mm mortar layer is then trowled on top of the mesh. Effortshould be made to make sure that the mesh reinforcement lays in the middle of the mortar. Thecenter post (PVC pipe with 3/8” MSR bars) with its vertical reinforcement rods tied into the roofmesh can be filled with mortar at the same time.It is best to leave the roof formwork up for at least 3 days. The newly plastered roof should becovered with plastic to cure the mortar until the formwork is taken down.ROOF FORMWORKThere are several different ways to construct a mortar roof using varying formwork designs.

FLAT SLAB ROOFUse timber planking supported by bush timber braces.

Erection of timber support for sloped roof slab at Rakiraki, Yale, KadavuSLOPING SLAB ROOFUse a notched timber frame supported by bush timber. Sheet metal is taken then cut to fitthe frame and laid on top of the timber frame inside the tank walls.

CONICAL ROOFUse pre-cut radial timber form which radiates wedge shaped timbers from the center post.These timbers are supported by bush timber and 100 x 50mm timber.

FINISHING TOUCHES1. After the roof formwork has been removed the underside of the roof should be checked for exposedmesh reinforcement. Exposed wires should be covered with mortar to prevent corrosion.2. A slurry made from hydrated lime and water can be applied to the outside of the tank. This willtend to paint the outside of the tank white and enhance sunlight reflection. A coat of white weatherproof paint can also be applied.3. The inlet and overflow holes are then chipped into the upper tank walls and the remainder of pipeworks attached.FILLING THE TANKThe tank must be filled slowly with water to allow the mortar to expand and reabsorb moistureslowly. Rapid filling can create cracking and failure. A shallow depth of water should be left in thetank for a week or so before filling. Suggested time schedules for filling the tank are as follows: Fill ¼ of the tank with water and let stand 1 week. Fill tank to half full, let stand 1 week. Fill tank ¾ full, let stand 1 week. Fill completely and use
