The Single-Source Solution for Plan and Spec

Mechanical Service & Systems (MSS) provides plan and spec execution for projects of all sizes. From plumbing and sheet metal to controls and fabrication, our teams deliver every scope under one roof. Our full-service approach creates safer job sites, reduces downtime, and lowers costs by increasing productivity.

The MSS Advantage in Plan and Spec Projects

Unlike many contractors, MSS completes fabrication and assembly in a controlled shop environment. By prefabricating up to 100% of system components, we improve safety, reduce labor time on site, and accelerate installation.

Ensure Your Next Project Is Safe, On-Time, and On-Budget

From HVAC and plumbing to boilers and controls, MSS brings every trade together under one roof for efficient plan and spec delivery. Get started today with Utah’s full-service mechanical contractor.

Total Capabilities Under One Roof

Our in-house resources set us apart from other contractors. MSS brings every element of a plan and spec vs. design build project together, helping clients save money and minimize disruptions.

Sheet Metal, Plumbing, and Fabrication

We design, fabricate, and install sheet metal, piping, and system components in our shop to ensure quality and safety. Prefabrication minimizes time on site, allowing businesses to maintain operations while upgrades are completed.

Controls and Boiler Integration

Beyond HVAC and plumbing, MSS integrates controls and boiler systems into plan and spec projects. This ensures every mechanical system works seamlessly together from the moment installation is complete.

How Our Experts Help Streamline Construction Projects

With MSS, our clients gain more than just skilled trades. They gain a partner that prioritizes safety, efficiency, and cost control. By fabricating system components in-house, we eliminate many of the risks and inefficiencies that come with on-site construction.

Prefabrication allows our teams to:

  • Reduce Labor Risks: Working in a controlled environment means better oversight, fewer safety hazards, and more predictable results.
  • Shorten Installation Timelines: Major assemblies are completed before they arrive on site, minimizing downtime and keeping projects on schedule.
  • Improve Accuracy and Quality: In-house fabrication ensures that every piece is built to exact specifications, reducing rework and costly errors.
  • Lower Installation Costs: Less time on site means fewer disruptions, faster completion, and long-term savings for clients.

FAQs About Our Plan and Spec Solutions

In a plan and spec vs. a design-build project, the design is completed by outside engineers and then executed by the contractor. With design-build, MSS participates earlier in the process to design and install systems from the start.

We provide plan and spec support for offices, tenant improvements, manufacturing, food processing, aerospace, and mission-critical facilities across Utah.

Plans show the physical layout of a project, while specs outline the materials, methods, and standards required. MSS can oversee both to ensure your project is built safely, efficiently, and to code.
