Mendocino Transit Authority Bus Maintenance Facility

The Project

The Mendocino Transit Authority (MTA) services a population of 90,000 across a 2,800-mile swath of northern California. Its vehicle fleet logs more than 881,000 miles annually. With numbers like that, it’s imperative to have a state-of-the-art shop to keep buses running in top shape. In August 2012, the Mendocino County agency dedicated its new bus maintenance facility in the county seat of Ukiah. The 17,196-square-foot structure features maintenance bays along with fueling and vehicle wash areas, plus storage space.

It was built with KingZip standing seam insulated metal roof panel and Optimo insulated wall panels. These panels consist of a simple yet smart design made from an insulated foam core material sandwiched between two metal skins.

These panels do not require painting or maintenance and are one of the many sustainable features of this project. The metal panels sit on a base of patterned concrete block walls that provide protection from vehicles.

Driving Forward

Division 13 President and Owner Marc Davis said Kingspan products were ideal for the maintenance building because of the panels’ durability, high insulation values, ease of installation, and eye-catching finishes.   Davis added that Optimo wall panels contributed greatly to the “architectural appeal” of the MTA project. “It’s a good-looking structure,” he said.


Style in Motion

A trio of sloped roofs gives the facility a sense of motion while north-facing above-eye-level windows allow outside light to pour into the interior space but without excess. The building earned a 2012 AIA Redwood Empire Chapter honor award in the “Built Project” category.
