An honest note on estimates
Construction costs depend on project specifications, location, materials, market prices and site conditions. Any estimate is only as reliable as the information behind it, and prices can change between estimate and purchase. We will not quote you a fixed cost or promise a percentage saving before your project has been properly assessed.
What we do provide is method: checked quantities, stated assumptions and regular tracking. That is what keeps budgets realistic and gives you time to respond when things change. If you want to understand the drivers first, read what really drives construction costs in Kenya.
Cost & BOQ questions
Can't find your question? Ask it directly — there is no obligation.
Ask on WhatsAppHow accurate is a preliminary estimate?
A preliminary estimate is a planning figure based on limited information. Accuracy improves as the design is developed and quantities are measured. We always state the assumptions and the information each estimate is based on.
Can you guarantee my project will cost a certain amount?
No honest professional can guarantee a final cost before construction. Prices, site conditions and decisions made along the way all affect it. What we provide is a realistic budget, clear assumptions and active monitoring so you can respond early when costs move.
Can you review a BOQ or quote I already have?
Yes. We review stated quantities and rates within the agreed scope, identify apparent omissions, inconsistencies or duplicated items, and support comparisons between contractor quotations.
Do you work with quantity surveyors?
Yes. BOQs are prepared or reviewed within the agreed scope and our professional competence. Where a project needs a registered quantity surveyor, we coordinate with one.
Can you check a payment request before I pay?
Yes. Our Cost and Payment Verification package reviews the payment request and supporting records against available site evidence and provides a written report to support your decision.
