In brief
- A revision that arrives without a register, a cloud or a signature becomes a second drawing on site, and crews build from whichever sheet they hold.
- Anyone can test revision experience before award by asking for one real revision history and walking a recent site to compare the drawing set against the work.
- Make one person the drawing controller, log every issue with its number and date, and mark superseded sheets on receipt rather than at the end of the job.

A gap in drawing revisions experience shows up when a Burao site builds from a superseded sheet. The revision exists, but nobody logged which number it replaced, which crew holds it or which work it affects. The structure then follows old dimensions, openings or levels. Fixing it later means demolition, not paperwork. The gap sits in the system around the drawing, not in the drawing itself.
How does the gap start on a Burao project?
It starts when a revision is issued without a document number, date, revision letter and a clear statement of what changed. A revised sheet can look almost identical to its predecessor, so the change may be a single dimension, a moved opening or a thicker slab. If the designer sends the file by message and no one records it, two versions of the same detail sit on site with equal authority. A sheet can then be reissued with no revision history attached at all. Ask the designer how changes are numbered and who confirms receipt. Ask the municipality what records exist for the plot and confirm the answer directly. Then check whether the site's drawing set matches what the designer last issued.
What does the gap do to the work?
Work gets built to obsolete details, and the error is buried before anyone notices. A footing cast to an old grid line, a wall built to a previous opening width or a slab set to an old level can be expensive to reverse once concrete has cured. Follow-on trades then set out from the built condition rather than the drawing, so one stale dimension repeats along the building. Rework can also mean cutting cured concrete or exposing work already finished, which raises the chance of a weak repair. None of this is a Burao condition. It is what happens anywhere when revision control is thin.
How do you test revision experience before award?
Ask each bidder to show one real revision history from a past job: the issue register, the revision numbers and the dates they were received. Then walk a recent site and compare the drawing set held there against the register. A team with real experience can point to a change, explain what it affected and show how the site was told. A team without it will struggle to produce the register or will offer only the final as-built set. Check who signs for drawings on site, how superseded copies are marked and how the designer is asked to confirm a change. General practice is to keep one controlled set on site, mark superseded sheets on receipt and log every issue with its number and date. Confirm those arrangements against the project's specification or engineer.
What to do next
Before the next concrete pour, take the site's drawing set and the issue register to the supervisor. Pick three details already built and ask which revision number each one follows. Where the answer is unclear, pause that work front and ask the designer for written confirmation of the current revision before it continues. General practice is for one named person to hold the master set; confirm this arrangement with the engineer.
Frequently asked questions
Who should control drawings on a Burao site?
One named person should hold the master set and the issue register, usually the site supervisor or a clerk of works. That person records each issue with its number and date, stamps superseded sheets and confirms receipt. Confirm the arrangement with the project engineer or specification.
Can a revision be issued without a new number?
It can be sent that way, but it should not be. Ask the designer to number, date and describe every change so the site can tell which sheet replaced which. Without that, two versions carry equal authority.
What records should a client ask for at handover?
Ask for the issue register, the final revision of each drawing and the confirmation that site copies match them. Also ask who signed for each issue, and confirm these records against the specification.
