Design life, inspection access and why bridge work is let on its own
Bridges are procured separately from the roads they carry because they are a different engineering and a different risk. Design is governed by load models and a design life measured in decades, with durability requirements -- concrete cover, waterproofing, drainage detailing, corrosion protection systems and bearing and joint selection -- that determine maintenance cost long after the contractor has left. Buyers increasingly evaluate whole-life cost on this basis rather than construction price alone.
Construction is dominated by temporary works and by what the structure crosses. Falsework and formwork design, launching or lifting operations, and the possessions required over a railway, a waterway or a live road carry most of the risk and most of the programme. Those possessions are granted by third parties in narrow windows, often at night, and a missed window is not simply rescheduled, so the contract concentrates liability around them and bidders are assessed on the credibility of their lifting and possession plans.
Assessment, strengthening and replacement of existing structures is a large part of this market and needs different skills from new build. It begins with principal inspection and load assessment against current standards, frequently on structures whose original records are missing, and it requires access -- under-bridge units, scaffolding over water, rope access -- that is a specified and priced part of the work. Weight restrictions, monitoring and interim propping while a permanent solution is procured are common interim deliverables in their own right.
This section describes how this category is bought generally, across the public buyers that publish it. The figures elsewhere on this page are measured for this market alone.

How long do bidders get to respond to bridges tenders in Kenya?
Across the 420 Kenya bridges notices that publish both a publication date and a closing date, the median response window is 11 days. A quarter of them allowed 7 days or fewer and a quarter stayed open for more than 14. 315 of them (75%) closed within a fortnight of being published, so on this market a bidder who reviews notices once a week can lose most of the response window before reading one.
How often are bridges tenders published in Kenya?
