Nigel Tangwanda

Commercial Construction Estimator with 9+ years of experience supporting contractors with quantity takeoffs, material takeoffs, and bid preparation for commercial construction projects.

My background working inside a general contractor estimating department provides a strong understanding of how real construction bids are assembled. This includes reviewing architectural and structural drawings, preparing detailed quantity takeoffs, coordinating subcontractor scopes, and organizing estimates that support competitive tender submissions.

I assist contractors who need reliable estimating support during busy bidding periods or when multiple projects are due at once.

Services include:
• Concrete quantity takeoffs foundations, slabs, footings, walls
• Material takeoffs from construction drawings
• Quantity summaries prepared in Excel
• Bid preparation support

Experience estimating commercial, institutional, residential, and agricultural construction projects across North America.
