Integrated Quantity & Construction Surveying
We provide the financial clarity, technical insight, and risk mitigation your projects deserve. From Quantity Surveying in London to Land Valuation in Lagos, we protect your investment before the first brick is laid.
Land & Engineering Surveying
Topographic Surveys: Mapping the elevation and features of the land before design starts.
Setting Out: Taking the architect’s digital blueprints and physically marking the ground (using pegs or GPS) so the builders know exactly where to dig foundations.
As-Built Surveys: Checking the work after it’s finished to ensure the building is exactly where it was supposed to be.
Quantity Surveying
Feasibility & Estimating: We calculate how much the project will cost before a single brick is laid.
Bill of Quantities (BOQ): We curate detailed document that lists every single material, nail, and hour of labor required, so contractors can provide accurate bids.
Cost Control & Variations: We monitor spending during construction. If the price of cement goes up or the design changes, the QS manages the “variation” to keep the project on budget.
Contract Administration: We handle the legal agreements between the client and the builder to ensure everyone is treated fairly.
