The assets around a road, and why they are often a separate contract
Road infrastructure as a procurement heading usually means the assets that make a carriageway work rather than the carriageway itself: drainage, retaining structures, barriers and restraint systems, signs and gantries, lighting columns, road markings, traffic signals and the ducting and detection that serve them. These are let separately from surfacing contracts because they are different trades with different certifications, and because their renewal cycles do not coincide with the pavement's.
Products in this category are type-approved rather than described. Vehicle restraint systems are specified by tested containment level and working width; signs by retroreflective class and by the standard governing their design; markings by retroreflectivity and skid resistance measured after laying; lighting by photometric performance against a lighting class. Bidders supply certificates against the specific product and installation configuration, and installers frequently need their own sector accreditation for work such as signal installation or lighting electrical work.
Working on a live road is the cost driver that separates competent bids from cheap ones. Lane closures are permitted in defined windows, often at night, under an approved traffic management plan with its own design, equipment and trained operatives; occupancy of the road is frequently charged or penalised by duration, so the programme is priced in hours rather than days. Bidders are normally required to hold sector qualifications for working on the network, and the buyer's permit regime -- who books the closure, how far ahead, and what happens if it overruns -- is usually a better guide to the real cost than the bill of quantities.
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 road & infrastructure tenders in Tanzania?
Across the 170 Tanzania road & infrastructure notices that publish both a publication date and a closing date, the median response window is 7 days. A quarter of them allowed 5 days or fewer and a quarter stayed open for more than 8. 160 of them (94%) 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.
