Many projects go out to tender without a clear Bill of Quantities. That forces the estimator and procurement team to guess at the scope — and a small omission or an over-count is often what decides whether a job makes or loses money. Bishop Engineering offers a dedicated BOQ & bidding service: we read the drawings, specifications and site conditions and produce a complete, line-by-line quantity take-off across the full project scope — engineering, materials and construction works — then build the priced bid on top of it.
Because the same engineers who design and build the work also estimate it, the BOQ reflects how the job is really constructed — realistic quantities, the right materials and codes, and the labour and indirect costs that are actually spent.
What we deliver
A complete Bill of Quantities — itemized by discipline, with units and quantities.
Quantity take-off from drawings — P&ID, isometrics, GA, civil/structural and electrical/instrument.
A priced bid / cost estimate — material, labour, equipment, subcontract and indirect costs.
A scope clarification log — assumptions, exclusions and items needing owner confirmation.
Tender support — pricing schedules, rate breakdowns and a basis of estimate.
Design to your budget
Tell us your target budget and we shape the BOQ and scope to fit it.
Value engineering — cut cost without cutting performance or compliance.
Options at different price points — material, spec and method alternatives.
Transparent trade-offs — clear changes at each budget level, nothing hidden.
Phasing — split the scope to match cash flow and priorities.
How it prevents over-scope and omissions
Nothing missed — a standard discipline checklist ensures no item is left out of the price.
Nothing over-scoped — quantities are tied to the drawings, not to guesses, so you don't price work that isn't there.
One clear scope — a documented assumptions and exclusions list protects you in negotiation and variation claims.
Easy procurement — a clean, structured BOQ that buyers can send straight to suppliers for quotations.
Win more, lose less — competitive bids that still protect margin.
Protect your margin — no forgotten items, no over-pricing.
Faster tendering — a ready BOQ shortens the bid cycle.
Stronger negotiation — documented scope backs you up in claims.
Fewer disputes and change orders during execution.
Procurement-ready — a clean list buyers can use immediately.
Built by people who build — realistic methods and productivity.
Confidence to bid — a complete, defensible number even from partial drawings.
How we work
Receive your drawings, specifications and scope — even if they are incomplete.
Take off quantities discipline by discipline against a standard checklist.
Flag gaps and ambiguities, and agree the assumptions and exclusions with you.
Build the priced BOQ — rates for material, labour, equipment and indirects.
Review for completeness and scope boundary — no gaps and no double-counting.
Deliver the BOQ and bid package, ready to submit or to hand to procurement.
Basis — Bill of Quantities structured to common tender practice; rates from current market data and Bishop Engineering project history; quantities taken off to project drawings and specifications.
