A TENDER (or BID) IS AN OFFER TO SUPPLY GOODS, WORKS OR SERVICES AT A STATED PRICE, MADE IN RESPONSE TO AN INVITATION. THE OBJECTIVES OF A PROCUREMENT PROCESS, which the rules exist to secure: · VALUE FOR MONEY — not the lowest price, but the best combination of price and quality for the purpose · TRANSPARENCY — the process visible and documented · FAIRNESS AND EQUAL TREATMENT of all bidders · COMPETITION — enough bidders to discipline the price · ACCOUNTABILITY — every decision traceable to a stated criterion · ECONOMY AND EFFICIENCY THESE ARE IN TENSION. Maximum transparency is slow; maximum speed invites arbitrariness. THE RULES ARE A COMPROMISE, and understanding them as a compromise explains why they are as elaborate as they are. ── METHODS OF PROCUREMENT ────────────────────────────────── OPEN / COMPETITIVE BIDDING — advertised publicly, any qualified bidder may participate. NATIONAL COMPETITIVE BIDDING (NCB) or INTERNATIONAL COMPETITIVE BIDDING (ICB) above a threshold value. THE DEFAULT METHOD, and the most transparent. Slowest, and requires the fullest documentation. SEALED QUOTATION — for smaller values; a limited invitation with simpler documents. DIRECT PROCUREMENT (single-source) — one supplier approached directly. PERMITTED ONLY IN DEFINED CIRCUMSTANCES: genuine emergency, proprietary goods with one source, continuity of an existing supply, or trivially small value. THE MOST ABUSED PROVISION IN PUBLIC PROCUREMENT ANYWHERE, which is why the permitted grounds are narrow and must be recorded. LIMITED / RESTRICTED TENDERING — invitation to a shortlist, used where only a few firms are capable. TWO-STAGE BIDDING — technical proposals first, refined through discussion, then priced bids. Used where the technical solution is not fully defined at the outset. PREQUALIFICATION — for large or complex works, bidders' capability is assessed BEFORE they bid, so that only qualified firms tender. It saves evaluating bids from firms that could never perform, and it saves those firms the cost of bidding. FRAMEWORK AGREEMENTS — a standing arrangement for repeated requirements. CONSULTANT SELECTION uses different methods because price is the wrong primary criterion for intellectual work: QCBS — QUALITY AND COST BASED SELECTION, weighting technical quality (commonly 70–80%) against price. THE STANDARD METHOD. QBS — quality-based only, for highly specialised work LEAST COST, FIXED BUDGET, or single-source in defined cases THE PRINCIPLE: FOR DESIGN WORK, THE COST OF A POOR DESIGN VASTLY EXCEEDS ANY SAVING ON THE DESIGN FEE, so selecting a consultant on lowest price is a false economy — and the procurement rules recognise this explicitly. ── THE TENDER DOCUMENTS ──────────────────────────────────── A complete set comprises: 1. INVITATION FOR BIDS / NOTICE — the advertisement 2. INSTRUCTIONS TO BIDDERS (ITB) — how to prepare and submit 3. BID DATA SHEET — the project-specific particulars 4. CONDITIONS OF CONTRACT — GENERAL (standard, often FIDIC or the PPMO standard) and PARTICULAR (project-specific amendments) 5. SPECIFICATIONS — technical requirements 6. DRAWINGS 7. BILL OF QUANTITIES (BOQ) — itemised quantities for the bidder to rate 8. FORMS — bid form, bid security, contract agreement, performance security 9. ELIGIBILITY AND QUALIFICATION CRITERIA 10. EVALUATION CRITERIA — WHICH MUST BE STATED IN ADVANCE AND APPLIED EXACTLY AS STATED. Introducing or reweighting a criterion after bids are opened invalidates the process, and this is the most common ground of a successful complaint. THE BILL OF QUANTITIES deserves a note: the CLIENT provides the quantities and the BIDDER provides the rates, so all bids are directly comparable line by line. IT ALSO MEANS THE QUANTITY RISK STAYS WITH THE CLIENT — if the actual quantity differs, payment follows the measured amount. A LUMP SUM contract moves that risk to the contractor, who prices it accordingly.

── THE TENDERING PROCESS, STEP BY STEP ───────────────────── 1. NEED IDENTIFIED, budget confirmed, procurement plan prepared 2. TENDER DOCUMENTS PREPARED, including the ENGINEER'S ESTIMATE, kept confidential 3. INVITATION PUBLISHED — in a national daily and on the e-GP portal, with a minimum period allowed for bid preparation (30 days for NCB, longer for ICB) 4. DOCUMENTS ISSUED / DOWNLOADED 5. PRE-BID MEETING and SITE VISIT — questions answered, and CRITICALLY, ANY CLARIFICATION MUST BE ISSUED TO ALL BIDDERS AS A WRITTEN ADDENDUM. Answering one bidder privately destroys equality of treatment. 6. BIDS PREPARED AND SUBMITTED, sealed, before the deadline. LATE BIDS ARE REJECTED UNOPENED — an absolute rule, because any discretion here is an opening for abuse. Each bid is accompanied by a BID SECURITY (bid bond), typically 2–3% of the bid value, forfeited if the bidder withdraws or refuses to sign after award. 7. BID OPENING — in PUBLIC, at the stated time, with bidders present; prices read aloud and recorded. 8. EVALUATION by a committee — the substance of the process, below. 9. AWARD to the successful bidder, with a STANDSTILL PERIOD during which unsuccessful bidders may complain. 10. PERFORMANCE SECURITY furnished (commonly 5% of the contract price) and the CONTRACT SIGNED. Bid securities are then released. 11. NOTICE TO PROCEED. ── EVALUATION: THE THREE STAGES ──────────────────────────── 1. PRELIMINARY EXAMINATION — is the bid complete, signed, accompanied by a valid bid security, and substantially responsive? A MATERIAL DEVIATION MAKES A BID NON-RESPONSIVE AND IT IS REJECTED WITHOUT FURTHER EXAMINATION, however attractive its price. Minor, non-material irregularities may be waived or clarified — but clarification MUST NOT ALTER THE PRICE OR SUBSTANCE. 2. TECHNICAL EVALUATION — does the bidder meet the qualification criteria: experience, financial capacity, key personnel, equipment, and does the offer meet the specification? 3. FINANCIAL EVALUATION — arithmetic checked, corrections applied under stated rules (unit rate normally governs over an extended total), bids compared, and the LOWEST EVALUATED SUBSTANTIALLY RESPONSIVE BID identified. NOTE THE PHRASE CAREFULLY: "LOWEST EVALUATED SUBSTANTIALLY RESPONSIVE BID", NOT "LOWEST BID". A bid must first be responsive and the bidder qualified; only then does price decide. THIS DISTINCTION IS THE MOST COMMONLY EXAMINED POINT IN THE TOPIC. ABNORMALLY LOW BIDS: a bid far below the estimate and the other bidders is a warning, not a bargain. The employer may require justification of the rates, and may reject the bid or demand additional performance security. THE UNDERLYING PROBLEM IS THE WINNER'S CURSE: in an auction of an uncertain-cost item, the winner is systematically the bidder who most underestimated the cost. A contractor who wins at an unsustainable price will pursue claims, cut quality, or fail — and the client's apparent saving is spent several times over in disputes. ── WHAT GOES WRONG ───────────────────────────────────────── COLLUSION / BID RIGGING — bidders agree in advance who will win and submit cover prices. Signatures include very close bid prices, the same firms rotating wins, and identical errors in different bids. SPECIFICATION TAILORING — writing the specification so that only one supplier can comply. INFORMATION LEAKAGE — the confidential estimate or a rival's price disclosed. UNREALISTIC QUALIFICATION CRITERIA set to exclude competitors. SPLITTING a contract into pieces below the threshold to avoid open bidding — an explicit offence under the Act. DELAYED PAYMENT by the employer, which prices itself into every future bid. FRONT LOADING — a bidder rates early items high and later items low, so as to be paid more at the start. The total looks competitive and the cash flow favours the contractor. DETECTED BY COMPARING ITEM RATES AGAINST THE ENGINEER'S ESTIMATE, not just the totals. THE STRUCTURAL DEFENCES, and why they exist: · public opening, so prices cannot be altered afterwards · pre-declared evaluation criteria · e-GP electronic submission, removing the physical bid counter as a point of leverage · a complaint and review mechanism with a standstill period · debriefing of unsuccessful bidders · blacklisting of firms found to have colluded or defaulted NONE OF THESE MAKE ABUSE IMPOSSIBLE. They make it require more people, which makes it more likely to be discovered — and that is the realistic standard against which procurement rules should be judged.
