Founder of Henderson Commercial Services and Neartime Reporting. Commercial manager, quantity surveyor, planner and software developer — working on major infrastructure projects across the UK.
Colin Henderson is a quantity surveyor and commercial manager with experience spanning major infrastructure projects across the UK. His background covers commercial management, change and claims, programme analysis, earthworks and productivity measurement — and increasingly, software development and AI-assisted tools.
The breadth of that experience is deliberate. Commercial issues rarely exist in isolation — they are connected to planning decisions, operational choices, estimating assumptions and contractual obligations. Understanding those connections is where the most valuable work tends to happen.
Henderson Commercial Services and Neartime Reporting both emerged from the same observation, repeated across project after project: the information needed to make better decisions usually exists somewhere — but it is rarely connected, rarely current, and rarely in a form that the people who need it can easily access.
Both businesses are a direct response to that observation — not as a technology venture, but as a practical attempt to improve the way projects understand themselves.
