In brief
- A quotation that names a concrete grade and a cement tonnage but no mix design or test frequency leaves the cost of compliance unpriced.
- Ask each supplier for the rate build-up, the wastage allowance and the test record list, then compare those, not the bottom line.
- Where a quotation has gaps, ask the municipal engineer's office which records it expects and price the missing items before award.

Supplier quotations in Hargeisa show skills gaps when they price materials by name and volume but not the work that makes the material comply. A quote that says "concrete, 30 m3" without a mix design, a wastage figure or a test frequency hides the cost of doing it properly. The gap sits in the knowledge of what a price must cover.
What do supplier quotations in Hargeisa usually leave out?
They leave out the items the supplier cannot describe, because describing them needs site knowledge. A quotation for ready-mix may name a grade but not the cement content, the admixture, the slump at discharge or who pays for cube testing. A quotation for rebar may give a tonnage but not the lap lengths, the cover spacers or the cutting and bending schedule. A quotation for blockwork may give a unit count but not the curing method or the rejection rule for cracked units. Each omission is a cost the client carries later. Ask the supplier to state, in writing, the specification the price assumes, the wastage allowance and the test records that will be handed over. If the answer is vague, the gap is real. For the local position on which records a building file should hold, ask the municipal engineer's office.
Why unsupported cost assumptions survive into the award
They survive because evaluation compares totals, and a total looks complete. A bidder with weak technical knowledge writes a quotation that reads like a price list. The evaluator, often working to a deadline, checks unit rates and addition, finds no error, and ranks the bid. Nothing in that process asks whether the price covers a slump test, a compaction layer or a curing period. The low total then becomes the benchmark, and the bidders who priced the missing work look expensive. The mechanism repeats: the gap in the quotation becomes a gap in the budget, then a gap on site. A supervisor who has seen the work can spot it. Walk a recent job by the same supplier and ask what was tested and what was rejected. The answer tells you what the next quotation is likely to omit.
How do you test a quotation before you compare it?
Set a short list of required lines and mark each quotation against it. The list can include: the specification and grade assumed; the wastage allowance and how it is calculated; who provides and pays for samples and tests; the delivery, unloading and storage arrangement; the programme or lead time; and the exclusions. Then ask one question of each bidder: show the build-up of the rate for the largest item. A supplier who cannot break a rate into material, labour, plant and wastage is working from a guess. Compare the completed lists, not the totals. Where a line is missing, add an allowance before you rank, and note it in the evaluation. Confirm any technical limit, such as cover, cure duration or test frequency, against the project specification or the engineer, since these are general practice and not local rules.
What to do next
Take the last three quotations you received and mark each against one list: specification, wastage, testing, delivery, exclusions. Send the gaps back to the bidders as written questions with a deadline. When the answers return, re-rank the bids on the full scope. If you are unsure which records a completed building should hold, ask the municipal engineer's office before you award.
Frequently asked questions
Should I reject a quotation that has no rate build-up?
Do not reject it on that ground alone. Ask for the build-up of the largest item in writing. If the bidder cannot explain how the rate was formed, treat the price as an estimate, add an allowance for the missing scope, and compare again.
Which records should a supplier hand over at completion?
The list depends on the specification. Typical items are delivery notes, batch or mix records, test results and as-built notes. Confirm the required list with the engineer or the municipal engineer's office before you write it into the order.
