Project Overview

As part of a long-term partnership with DTE, NTH has played a central role in revitalizing the Warren Service Center (WSC)—a critical 52-acre operations hub with a legacy dating back over a century. Our multi-year program included phased construction for a campus-wide asset management and improvement plan, focused on enhancing long-term performance and minimizing operational disruption.

Project Scope

The work NTH has performed at WSC has included the following major services:

  • Roofing Assessment, Design and Quality Assurance: The roofing design addressed complex building configurations such as Building G’s mix of
    saw-tooth and flat roof systems and supported critical equipment operations with full-time quality observation and lifecycle planning.
  • Stormwater Assessment, Flooding Mitigation, and Upgrades: NTH also conducted a stormwater evaluation to mitigate recurrent flooding, delivering a comprehensive model and improvement plan that enabled DTE to make informed capital planning decisions. The entire north half of the campus was upgraded, including rerouting of roof drainage, upsizing stormwater pipes, and installation of a stormwater detention pond to increase system capacity and mitigate long-term flooding concerns.
  • Fire Suppression System Main Upgrades: NTH led the design and construction oversight of a complete overhaul of the site’s fire protection infrastructure, replacing aging systems with a new 1,500 gpm prefabricated fire pump house, underground water main, and upgraded connections to five buildings. This effort included permitting, stakeholder coordination, and decommissioning legacy components like the on-site fire reservoir.
  • Space Planning and Warehouse Upgrades: When warehousing, storage, and space needs changed, DTE had NTH assist with evaluating the space and developing a comprehensive plan to improve access, storage, and logistics at their warehouse, Building W. NTH developed comprehensive space planning upgrades to facilitate improved and upgraded warehousing capacity for the site including storage rack design, access improvements, and utility upgrades.
  • Building Demolition Assistance and Site Access Improvements: Our team also managed the complex demolition of Building H and associated site improvements, including hazardous material abatement and new perimeter security features. Upgraded access included new perimeter security wall design, new guard house and access entrance design, and security fence access. Improvements to site lighting, communications, and stormwater /water infrastructure were also included in the project. Through these efforts, NTH helped DTE advance site reliability, safety, and readiness for future redevelopment.
