Associate Principal

MEP Engineering

James is a trained mechanical engineer who has spent a considerable amount of time within the consulting and client side of the industry. Working for the first 7 years of his career on the consulting side before spending 4 years on the client side, James brings a unique skillset and perspective to the REX team. From initial site selection, landlord lease negotiations, and concept design to construction administration, facilities coordination, and post-occupancy commissioning – James has the capabilities to see a project through from start to finish. Spending an extensive amount of time on-site has lent James the ability to make informed, robust decisions with significant impact on not only mechanical, but electrical, plumbing, bms, and fire protection disciplines. Directly working with architect and contractor colleagues has allowed James to hone his communication and project management skills in order to manage expectations and deliver a project that satisfies all parties.

James’s project experience includes higher education, single and multi-family residential, commercial, retail, performing spaces, K-12 education, and industrial. James is passionate about sustainability and tries to implement as many energy-efficient technologies as a project may allow. With a focus on schedule, budget, and simplicity, James strives to develop and deliver a project that is constructible within the budget and time constraints.
