General Engineering Knowledge and Engineering Practice: Contracts, Procurement and Compliance
General Engineering Knowledge and Engineering Practice tests the rules that decide whether a public works project is delivered lawfully: procurement procedure, contract administration, measurement and payment, quality assurance, occupational safety and environmental clearance.
Procurement and contract
- Public procurement follows the national Procurement Guidelines; works above the prescribed threshold go to National Competitive or International Competitive Bidding.
- Works bid documents commonly follow CIDA/ICTAD standard bidding documents, with FIDIC-type conditions on donor-funded contracts.
- Bid security (commonly 1–2% of bid value) is released to unsuccessful bidders; performance security (commonly 10% of contract price) runs through construction.
- Retention is typically 10% of each interim payment, capped at 5% of the contract sum.
- Variations are valued at BOQ rates where the work is similar, otherwise at a new rate built up from labour, plant and material.
Environment and safety
- The National Environmental Act requires an Initial Environmental Examination or EIA for prescribed projects, with approval from the Central Environmental Authority.
- The Factories Ordinance and its regulations govern machinery guarding, scaffolding and safety officers.
Worked example
Contract sum Rs. 100 million, retention 10% capped at 5%. After a Rs. 30 million interim payment, retention held is Rs. 3 million; from the ninth payment onward it stops at Rs. 5 million. If the contractor abandons the works, the employer calls the performance security, while retention is applied to defects - it is not a penalty.
Traps
- Treating bid security and performance security as the same instrument.
- Granting extension of time for delay on a non-critical activity.
- Certifying provisional-sum work as though it were a variation.
- Confusing the defects liability period with the retention period.
