How do you compare bid scopes for a Garowe build?

How do you compare bid scopes for a Garowe build?

Start by rewriting every bid into one scope sheet, line by line, before you look at prices. Unverified capability is a common risk when comparing bid scopes: read what each tenderer actually offers, not what the covering letter claims. When two bids describe the same building but not the same work, the lower price buys a narrower package, and the difference surfaces later as extras, stalled trades or rejected work.

Why do noncomparable tender prices hide risk?

Noncomparable tender prices hide risk because each price answers a different question. One bidder may price excavation to a depth with no backfill, another may include cart away, and a third may leave both to a variation. Read the bills in the same order and mark what each line includes: material grade, quantity, wastage, testing, plant, labour, supervision and curing.

Ask each bidder to state assumptions in writing: ground conditions expected, water source for mixing and curing, working hours, access, and how they will handle rock or groundwater if it appears. Ask the municipal engineer's office what permits and inspections the plot needs, and put those items on the sheet as required lines. Water carting and storage can change the work regardless of the concrete volume, so confirm the source and storage against the project's specification. A bid that omits curing water or formwork reuse may be priced elsewhere or carry risk the client ends up accepting, so mark the gap and ask.

How do you test a bidder's claimed experience?

Test claims by asking for evidence you can read and walk. A claim of past similar work is a starting point, not proof. Ask for concrete cube or compaction test records with dates, delivery notes for steel and cement, and two recent sites the bidder completed or supervised. Visit one without warning where possible and look at the actual detailing: cover to reinforcement, joint layout, fall to drains, and how waste was managed.

For each key person named in the bid, ask what they did on that job and who supervised them. Request the calibration certificate of any testing equipment the bidder says it owns, and ask which laboratory it uses. If a laboratory holds the records, ask the laboratory directly whether it tested for that bidder, rather than relying on a copy. Keep the questions in the tender clarification stage, and record the answers in the evaluation file with dates.

Where does the competency gap open in Garowe evaluations?

Paperwork alone can score a bid that the site would fail. A bidder can list plant, staff and experience that the firm does not control, and a low price then looks competitive rather than incomplete. Compare technical submissions against the same checklist: named supervisor with site hours, owned or hired plant with availability, method statement with sequence, quality control with test frequency, and safety arrangements for working at height or in excavations.

Ask the client's engineer to confirm general practice limits, such as concrete cover, curing duration, and trench support, against the project specification rather than accepting a bidder's rule of thumb. Where a bidder cannot answer a technical question at clarification, note it and check whether the same gap appears in the method statement. Two or three unanswered questions across a scope can mean the firm has not done that work before, whatever the reference list says.

What to do next

Build one scope comparison sheet with a column per bidder and a row for every required item. Add a second sheet listing the evidence you demanded and what arrived. Send written clarification questions to any bidder whose scope is unclear, and ask the municipal engineer's office for the permit and inspection list for the plot. Rank prices only after the scope columns match.
