Derek Graham

I’m Derek Graham, President of RepOne. Although I hold a degree in British Literature, my background is “up through the ranks.” My roots go back to my father’s workshop. I have “worked the tools” since 1982, when I began as a laborer, and next a carpenter in 1985. I continued as an architectural mill-work fabricator and installer until 1993, when I moved into management as a superintendent, later, as a project manager and chief estimator, and then Director of Operations. I now work in project controls: budget and schedule. My specialty is in luxury and high-end projects.

Please feel free to connect with me on LinkedIn.

I work regularly with partners from the design and building industries, who assist on projects with advanced engineering, design, or other technical disciplines, including: mechanical engineers, architects, specialty contractors, and other independent consultants.

Presently, I am a Primavera 6 scheduler and schedule oversight consultant for public and private sector projects, up to $4B. I work for owners, architects, construction managers, general contractors, and legal industry professionals. Much of my oversight work has to do with analyzing the integrity of project schedule baselines and updates. This I did for several Metropolitan Transit Agency projects, among others:

MTA East Side Access

MTA Second Avenue Subway

MTA Fulton Street Transit Center

WTC Transit Hub

TBTA Brooklyn Battery Tunnel

I act as a construction expert witness and claim preparations specialist in construction disputes for both owners and builders. I have acted as an expert witness for construction litigation cases in several states, since 2006, as well as Federal Cases.
