- Supporting Virginia’s Largest Infrastructure Project: Wilmot’s Role in the Hampton Roads Bridge Tunnel Expansion
Table of Contents
Introduction
The Hampton Roads Bridge-Tunnel Expansion is the largest highway construction project in Virginia’s history, with a budget exceeding $3.9 billion. Spanning nearly ten miles of the I-64 corridor, this transformative infrastructure project aims to relieve congestion, improve travel time reliability, and enhance regional connectivity. Central to this effort was the need for a functional, centrally located workspace to support HRCP’s team. Wilmot Modular Structures, Inc. delivered an innovative solution by designing and installing a two-story, 32-plex modular facility that met the project’s unique challenges and high standards.

Architectural Excellence
Architectural Excellence
HRCP entrusted Wilmot Modular with the challenge of providing 29,120 square feet of office, conference, and administrative space. The resulting design combined functionality, durability, and aesthetic appeal to support the team’s daily operations.
Key architectural highlights:
- Perimeter offices: Designed for privacy and productivity, accommodating a range of team roles.
- Central core workstations: Open bullpen-style areas encourage collaboration and team synergy.
- Kitchenettes and huddle rooms: Strategically placed for convenience and flexibility during the workday.
- Custom windows: Large windows strategically positioned to offer critical vantage points for senior leadership.
- Integrated access: Four site-built stair towers, including one directly connecting the facility to an adjacent cafeteria building for seamless access between structures.
These elements ensure a professional, functional environment tailored to meet HRCP’s operational requirements while maximizing available site space.
Chapter 2:
Technical Innovation
This project represents a landmark achievement for Wilmot Modular as its largest multi-story modular structure to date. The design and construction process showcased Wilmot’s technical expertise and ability to manage complex challenges.
- Oversized Modules: Each module measured 14 feet wide by 65 feet long, far larger than standard modular units, requiring precise coordination for delivery and staging. Temporary tunnel closures and nighttime deliveries ensured safety and minimized traffic disruption during installation.
- Site Constraints: The limited area for cranes, material laydown, and employee parking demanded meticulous planning and on-the-ground coordination to optimize space and time.
- Foundation Design: A custom at-grade pier system provided stable support while minimizing the need for site grading.
- Seamless Integration: Concrete sidewalks intricately connect the facility’s multiple egress points with adjacent buildings, ensuring accessibility and operational cohesion.
This project underscored the advantages of modular construction, particularly in handling space limitations, tight deadlines, and high-demand environments.
Chapter 3:
Cost Savings
Wilmot’s value-engineering approach provided significant cost savings by optimizing design and material usage. Key cost-saving measures included:
- Using wider modules, which reduced the total number of units required by six, saving on delivery, setup, and materials.
- Reducing the number of electrical panels and HVAC units, which further streamlined the construction process and minimized operating costs.
- Efficiently managing resources to shorten the installation timeline, reducing labor costs.
This thoughtful design and construction choices resulted in a highly functional building delivered within budget and ahead of schedule.
Chapter 4:
Green Building Practices
Wilmot’s modular approach aligned with sustainable building practices to minimize environmental impact:
- Off-site fabrication: Reduced on-site construction waste and limited disruptions to the project area.
- Energy efficiency: Design features optimized energy use, ensuring long-term environmental and operational benefits.
- Minimal site disruption: The quick installation process minimized environmental and community disturbances, showcasing modular construction as a sustainable alternative to traditional methods.
