About

Modulus is a specialist consultancy in Cost, Project, Contract, and Construction Management. Drawing on over 8 years of international experience, we pair financial discipline with hands-on site leadership to provide transparent cost certainty, robust contract governance, and measurable results. We take personal responsibility, offering a single point of accountability from boardroom to build, and we treat quality as a duty, not a checkbox.

Our integrated approach plans, supervises, and verifies quality at every stage; enforces clear change management and firm contract compliance; and actively owns risk. The outcome: every decision is justified, every cost is defensible, and every project stands up to scrutiny, delivering measurable value.
