D’Ambra Construction Site Office
D’Ambra Construction Needed a Site Office—Fast
D’Ambra Construction, a California-based construction and remodeling company, needed a functional office that could be deployed quickly to an active job site. The space had to be secure, comfortable, professional, and ready for daily crew use without the delays or recurring rental costs of a traditional modular trailer.
The goal was to create a turnkey construction office that D’Ambra could own, relocate, and reuse as projects changed. With less than three weeks available before mobilization, the schedule was tight—but Conexwest knew exactly how to approach the build.
Starting with a 40ft High Cube Container
The project began with one new 40ft high cube one-trip shipping container.
The high cube format provided additional interior height, leaving enough room for insulation, steel framing, lighting, climate control, and finished interior surfaces without making the office feel cramped.
From that original steel shell, Conexwest developed a complete office package built around the practical needs of an active construction site.
A Three-Week Build Window
The schedule was the project’s biggest challenge. D’Ambra’s mobilization date left less than three weeks for design, fabrication, interior finishing, painting, delivery, and placement.
There was little room for delays, especially those caused by coordinating multiple outside vendors. The office also needed to arrive ready for site power, year-round climate control, secure access, and regular crew use.
This required more than a basic container conversion. Before delivery, the unit needed:
- Secure personnel access
- Natural light and ventilation
- Heating and air conditioning
- Durable interior finishes
- A complete electrical package
- A fast connection to job-site power
The Conexwest Solution
Conexwest completed the project through its in-house design and fabrication team, reducing the scheduling gaps that often come with using multiple subcontractors.
The container was modified with a locking personnel door, dual-pane sliding windows, insulated and finished walls, durable flooring, a complete electrical system, and a wall-mounted air conditioner with heat.
A 60-amp disconnect was installed so the office could connect directly to shore power at the job site. This reduced the amount of electrical work required after delivery and helped the office become operational faster.
All fabrication was completed at Conexwest’s Lathrop facility. Once finished, the office was transported by flatbed and craned into position.

The Result
The completed container became a fully functional construction office delivered within D’Ambra’s three-week mobilization window.
Unlike a rented modular trailer, the office became a long-term company asset that could be owned, relocated, and reused across future job sites.
The project showed how a modified shipping container can provide a faster and more flexible alternative to a temporary site trailer without sacrificing security, comfort, functionality, or appearance.
What Made This Project Different
The compressed schedule defined the build.
By managing structural modifications, electrical work, insulation, interior finishing, painting, and delivery through one coordinated process, Conexwest avoided unnecessary scheduling gaps and completed the office without relying on multiple outside fabrication vendors.
The result was a customized site office delivered quickly, kept within budget, and designed to continue serving D’Ambra beyond a single construction project.
