COST ESTIMATE GUIDELINES AND REFERENCES

How to Avoid Bidding Errors

A. Read thoroughly plans, specifications, and general conditions of

contract, addendums, and invitation to bid. Study carefully the following terms

and conditions.

1. Bid bond – 5% to 10% Cash or manager’s check

2. Time of completion – number of working days or calendar days

3. Performance bond – all risk insurance 10% to 20% of contract.

a. Work Guarantee Bond – 20% to 30% of contract

4. Construction Bond for Residential – Subdivision Requirements

5. City Tax or Contractor’s Tax

6. Contractor’s insurance – Verify approved insurance company

7. Liquidated damages for 1% of 10% of bid

8. Price Escalation/ Time Extension

9. Revisions, changes, extra works

10. Last minute addendums, bid bulletins, time and date of the bid

submission

11. Owner-supplied materials

12. Terms of Payments – Check Dpayments

13. Permits

Construction Permits (Architectural, Structural, Plumbing, Mechanical &

Electrical

Occupancy Permits

Demolition & sidewalk Permits

City tax new codes

14. Building Code Requirements/Boundaries

1

B. Look for confusing requirements or any discrepancies in plans

and specifications. Refer to architect and owner in writing ( black & white)

C. Look for notations on plans – general scope of work, changes,

alterations, impossible requirements, Building code requirements

D. Evaluate & study carefully specifications

1. Make list of trades, brand, type that can fulfill the contract

2. Subdivide each trade list if needed

3. Ask quotations from subcontractors

4. Electrical, plumbing and mechanical if required.

Make sure you know the subcontractor suppose to quote on you. Set forms

to avoid gaps and mistakes

E. Set procedures for preparing bids

1. Plan the bid like a project with checklist, target date and project checklist

2. Check if bid required itemized cost breakdown/ unit cost of materials.

F. Check and double check take-off estimate. It might have been

overlooked. Spot check subcontractor proposals if complete. Take note of scope

of works. Verify items not included, unit cost of materials.

G. Site inspections – Verify thoroughly the following conditions.

1. Existing facilities to be demolished – wood, concrete steel.

2. Hauling In/ Out of matls– Disposal of debris. Location. Tools and

Equipment to be Used

3. Sources of Materials – Verify materials unit cost of nearby suppliers.

Major materials from existing supplier and minor materials from new supplier.

Verify terms of payment. Prepare materials checklist. Always check Current

Cost of materials, prepare checklist.

2

4. Geographical conditions of site. Slopes, verify on plans, if backfilling is

required. Check if adobe, soil of backfill. Note depth of excavation requires.

Hauling in/out of backfilling, Dumping of debris from site.

5. Ideal location of bunkhouse, temporary warehouse or storage.

Temporary utilities. Dumping of materials to site must not have conflict with

the layout of proposed building.

6. Sources of manpower, technical expertise, tools and equipment

7. Temporary facilities- power, water, telephone

8. Future tapping of the following:

- Power

- Water

- Telephones

- Sewer and Drainage

Verify if in conformity with the plans. Check utility company

requirements. Project Study. Roads, sidewalks to be demolished.

Permits and payments.Deposits c/o Owner

H. Use the “RULE OF THUMB” method. Check the most contentious

items of bid. Recheck addition of subcontractors.

I. Analyze the bid even if it is not successful. Update cost of

materials. Check file records and other historical data. Get result of bidding and

prepare feedback for future references.

J. Major error in bid. Determine whether or not to continue work on the

project. Determine if you are willing to live with the error. Know the bid of other

contractor.

K. Take note of indirect cost, VAT and other government taxes and

requirements.

Subdivision requirements, construction bonds, insurance, city tax, performance bond.3

L. You may wish to withdraw the bid.

Reminders before Estimating

A. Read first plans, specifications and general conditions of contract to familiarize

yourself with the general scope of works.

B. Spot check nebulous requirements if available in local market. Verify if imported,

suppliers, type of materials

C. Rough estimate to try. It must be 30-50% of what might be the ultimate cost.

D. Preliminary estimate. Unit cost obtained from past project. Recheck verify current

unit cost.

E. Always use the rule of thumb in the final estimate

F. RE-check your estimate. Let someone do it. Spot check multiplications and

additions of subtotal

G. Ask for quotations of suppliers or subcontractors of specialty works

H. Use different techniques in estimate

1. By volume method

2. BY area method – sq. m.

3. By direct count

Be systematic. Breakdown estimate or use the area method.

Schedule organized breakdown.

I. Begin estimate with fresh mind. Difficult items first, easy items like addition of total

cost can be done when you are tired

J. Always use your imagination, observation, take note of items lacking or errors in

plans and specifications. Do not leave items. Immediately look for unforeseen

requirements before continuing to other portion.
