Thornton Academy — Miles Field House

Saco, Maine · with Benchmark Construction

The challenge

Condition a 49,000 sq ft athletic and wellness facility with wildly variable occupancy, from empty mornings to full-capacity events.

What Mash installed

Rooftop units, large-scale ductwork distribution, and zoned climate controls for courts, an indoor track and support spaces.

What made it difficult

High-bay air distribution over an active athletic floor, plus tight sequencing with the general contractor and other trades on a school schedule.

The outcome

Even comfort across the field house with controls the school's facilities team can operate and maintain day to day.

Project Overview

The Miles Field House at Thornton Academy is a nearly 49,000-square-foot multi-use athletic and wellness facility featuring three full courts, an indoor track, sprint lanes and a modern training center. Working alongside Benchmark Construction, Mash Mechanical delivered the mechanical systems that keep the building comfortable, efficient and quiet through Maine's full range of seasons.

High-bay athletic spaces are demanding: large volumes, heavy occupancy swings and strict acoustic expectations. Our team coordinated ductwork through the truss system, set rooftop equipment, and balanced and commissioned the building so air distribution stays even from court level to the elevated track.

Scope of Work

  • • Rooftop unit installation and rigging coordination
  • • Spiral and rectangular ductwork through exposed truss framing
  • • Ventilation for courts, track, training center and locker areas
  • • Hydronic piping and specialty equipment connections
  • • Controls integration, test-and-balance, and commissioning
