BOQ Questions
A Bill of Quantities (BOQ) is a document that lists every material, work item, and quantity needed to construct a building, along with its unit rate and total cost. Contractors use it to price a project, and clients use it to understand exactly what they are paying for.
A cost estimate gives a single approximate total, often based on area or building type. A BOQ breaks that total into individual line items — excavation, concrete, rebar, blockwork, finishes — each with its own quantity and rate. A BOQ is more detailed and is usually required for tendering and contractor bidding.
At minimum: building use, built-up area, number of floors, foundation type, and finishing specifications (wall, roof, floor, paint). A detailed structural BOQ additionally needs approved drawings with column, beam, and slab dimensions.
A BOQ is used to request quotations from contractors, compare bids fairly on the same basis, track project costs during construction, and support loan or budget applications with a professional, itemized cost breakdown.
A Quick BOQ estimates cost from building type, area, and general specifications — useful for early budgeting in minutes. A Professional BOQ is calculated from actual approved structural drawings, giving precise quantities suitable for tendering and contractor agreements.
Yes. AddisBOQ's Advanced tier calculates structural quantities directly from your column, beam, and slab dimensions once your design is approved, producing a precise, itemized structural BOQ.
The Classic (Quick) BOQ gives a reliable preliminary estimate for early planning. The Advanced (Structural) BOQ, calculated from your actual drawings using Ethiopian building code detailing rules, is significantly more precise. Both should be verified by a licensed engineer before procurement.
A Quick BOQ is meant for early budgeting, not final procurement. A Professional/Advanced BOQ from approved drawings is much closer to a manual quantity takeoff, but final figures should still be reviewed by a licensed structural engineer.
Construction Cost Estimation
Cost varies widely by city, finishing quality, and building size — typically ranging from a modest local-finish home to a premium finish villa at several times that rate per square metre. Use AddisBOQ's calculator for an estimate specific to your city and specifications.
Estimators combine built-up area, structural system, foundation type, wall and roof materials, and finishing quality with current local material and labor rates, which vary by city and change with the market.
Material transport distance, local labor rates, supply availability, and demand all differ between cities like Addis Ababa, Hawassa, Adama, and Bahir Dar, causing the same building to cost differently depending on location.
Built-up area, number of floors, foundation type, structural system, wall and roof material, floor finish, paint quality, electrical and sanitary standard, and city all directly affect total construction cost.
Not on its own. Cost per square metre is a useful starting point, but it ignores foundation type, number of floors, and finishing quality — three factors that can change the total cost significantly for buildings of the same area.
Because floor area alone doesn't capture foundation depth, structural system, number of floors, finishing quality, or MEP standard — all of which vary independently of area and directly affect cost.
Yes. Taller buildings need larger foundations, thicker lower columns, and more structural reinforcement, so cost per square metre typically rises as floor count increases.
Yes, significantly. Isolated footings are typically the most economical, isolated footings with strap beams add moderate cost, and mat/raft foundations — needed for poor soil or heavy loads — cost considerably more.
Yes. Floor finish, paint quality, door and window profiles, and sanitary fittings can shift total cost substantially — the gap between economy and premium finishing is often a large share of the overall budget.
About AddisBOQ
AddisBOQ is a web and mobile platform built by a structural engineer to calculate construction costs and generate professional Bills of Quantities for Ethiopian building projects.
Estimating construction costs for early planning, generating a professional Excel BOQ for tendering, and — for structural projects — calculating precise material and rebar quantities from approved drawings.
You enter your project details — city, building use, floors, foundation type, and finishing specifications — and AddisBOQ calculates a full itemized Bill of Quantities with current Ethiopian market rates, ready for Excel export.
Homeowners planning a build, engineers and contractors preparing tender documents, consultants estimating projects for clients, and anyone who needs a fast, standard-format Ethiopian BOQ.
AddisBOQ currently supports Addis Ababa, Hawassa, Adama, Bahir Dar, Dire Dawa, Harar, Jigjiga, Arba Minch, and Wolaita Sodo, with more cities being added.
Yes. AddisBOQ supports buildings up to 10 floors above ground, including basement levels, for villas, apartments, commercial, and office buildings.
