Project tendering in Kenya: bidding and procurement for developers

Open tender, negotiated tender, and direct appointment each need complete documents. Incomparable bids are a documentation problem, not a contractor problem.

Tendering is how price meets documentation

Project tendering converts coordinated drawings, specifications, and bills of quantities into comparable contractor prices. Weak tender documents produce incomparable bids — the lowest number is rarely the same building as the next bidder.

For developers, tendering is also a governance moment: transparency, evaluation criteria, and award records protect against disputes and lender scrutiny.

Consultancy tendering vs construction tendering

Architects and quantity surveyors compete for appointments through proposals and interviews — scope clarity and realistic fees matter. Contractors compete on construction tenders backed by a complete BOQ and spec. Mixing the two processes (e.g. contractor-led design) changes risk allocation; document that choice explicitly.

Public-sector influenced projects must respect procurement law constraints; private developers still benefit from structured open or selective tender routes.

Building a tender package that prices

Minimum package: drawings (architectural, structural, MEP), specification, BOQ, programme assumptions, site logistics, preliminaries, and contract form. Addenda should be issued in writing with dates — not WhatsApp sketches.

Pre-tender meetings clarify ground conditions and access; answers are circulated to all bidders to keep comparison fair.

Evaluation and award

Score on price, programme, methodology, team, and relevant experience — weightings decided before bids open. Negotiation with the preferred bidder should not rewrite scope silently; variations belong in a controlled post-tender clarification log.

Award letters and signed contracts follow board or client approval; losing bidders should be closed out formally to reduce challenge risk.

Links to BOQ and contract admin

Read the bill of quantities guide and contract administration article next. REDM keeps tender issue dates, addenda, and award records on the project file for audit trail.

Tender security, bonds, and mobilisation

Tender documents should state bid validity period, tender security if used, performance bond expectations, and insurance requirements. Contractors price risk they see — silent bond requirements appear later as claims.

Clarify whether provisional sums cover statutory fees, contingencies, or client-supplied items. Separate preliminaries for site establishment, hoarding, and environmental controls on coastal sites with tight access.

After award, issue a letter of intent only if contract terms are ready; otherwise mobilisation payments lack a framework. Record award board minutes and evaluation scores — private developers face lender and partner diligence too.

What to do in the next two weeks

Freeze a tender issue set: drawings, spec, BOQ, programme, preliminaries, contract form, and clarifications log. Number revisions; reject site changes without addenda.

Run evaluation with written weightings before opening prices. Keep minutes. Negotiate clarifications in writing with all tenderers if fairness matters.

After award, transition records to contract administration — tender comparisons support final account disputes later.

Compare bids on a normalised sum — check exclusions, provisional sums, and currency of rates. The lowest headline often omits preliminaries you will pay later.

If only one bid is viable, document why selective tender was used and retain evaluation sheets for governance.

Invite the successful contractor to a pre-start meeting covering programme, site logistics, environmental controls, and communication protocol.

Deeper notes for board and lender packs

Two-stage tendering (design then build) shifts risk — document which design liabilities remain with the developer. Single-stage lump sum needs complete documents.

Domestic sub-contract packages (kitchens, lifts, pools) should be either in main contract scope or listed exclusions — gaps become site arguments.

Currency and tax assumptions must be stated in the tender letter. Import-heavy coastal projects move with forex — allow transparent adjustment rules if needed.

Digital tender submission is increasing — confirm file formats and naming so QSs can check completeness before the deadline.

Keep tender opening minutes with attendees listed. Even on private jobs, governance reduces challenge risk from losing bidders.

Align tender programme with realistic approval dates — contractors price delay costs if they expect slow possession.

On Kenyan coastal projects, document every decision that affects cost, approvals, or programme in the REDM project file so consultants, lenders, and your own board see the same timeline. Informal agreements scattered across email are where disputes start.

Before the next fee milestone, confirm who signs, who certifies, and who records — then hold one coordination meeting with minutes. Developers who skip that step usually pay twice: once for rework and once for dispute advice.

Pair this guide with the design-stage and statutory approvals articles so by-law, environmental, and tender assumptions stay consistent from predesign through handover.

Frequently asked questions

Is lowest tender always best?

No. Compare completeness, programme, exclusions, and contractor capacity. Incomplete BOQs make low bids imaginary.

Can we tender on scheme design only?

Possible for select contracts, but risk of variation claims rises. Preferred route is coordinated working drawings and BOQ.

What makes bids incomparable?

Different spec assumptions, missing preliminaries, unequal provisional sums, and unissued clarifications.

When is negotiated tender acceptable?

For repeat contractors or small works — still document scope and price basis. Large private projects often use selective tender.

Who prepares the BOQ?

The quantity surveyor from coordinated design information, not the contractor before award.
