Construction for the Adams County Public works Campus began in 2020 and completed in July 2023. The Campus consists of 3 separate buildings for Adams County including The Fleet Maintenance Building, The Public Works Building and the Auto Wash Bay Building. The Fleet Maintenance Building is where the County maintains and repairs their vehicles and large trucks, the Wash Bay is where they wash the vehicles and the Public Works building is for Administrative staff and minor vehicle maintenance. The Fleet Maintenance and Public Works Buildings both have boilers, air handling units and hydronic VAV boxes for the primary heat source. The Fleet Maintenance Building also has over 5 miles of in-floor radiant heat in the maintenance bays which is supplied from a heat exchanger and independent radiant heating system. All 3 buildings have a large compressed air system consisting of individual drops (stations) located throughout the buildings.

Midlands Mechanical was selected by Boulder County to deliver a complete chilled water system upgrade for the Saint Vrain HUB facility in Longmont, Colorado. The project required furnishing and installing a new air-cooled chiller and integrating chilled water service into an existing occupied building that previously had no chilled water infrastructure. The installation supported two existing air handling units in the south building and included provisions for a future air handler in the north wing. 

The south building contained modern RTUs equipped with chilled water coils that were not connected, while the north wing contained a 30-year-old DX rooftop unit scheduled for future replacement. The new chilled water system allows Boulder County to transition toward a more efficient, centralized cooling strategy consistent with updated HVAC design standards.

Scope of Work & Responsibilities:

Mechanical Installation

Midlands Mechanical’s complete mechanical scope included:

• Furnishing and installing an air-cooled scroll chiller.
• Installing chilled water piping to two existing air handlers in the south building.
• Providing piping stubs for a planned future air handler.
• Installing all pumps, valves, insulation, glycol feeder, and accessories for a fully operational chilled water system.
• Performing all demolition, cutting, coring, excavation, backfilling, and patching required for piping routes.
• Providing all mechanical permits for the project.
• Completing system balancing and commissioning per specifications.

Site Coordination & Logistics

• Work was performed in an occupied facility, requiring strict adherence to Boulder County’s operational schedule.
• Noisy or disruptive activities—especially piping work across the 3rd-floor ceiling—were required to occur outside public hours (before 8:00 AM or after 6:00 PM).
• Work in the atrium and entry areas required special barricade protection, monitoring, and traffic control.
• Coordination was continuous with Boulder County Building Services, which acted as General Contractor and performed their own electrical, drywall, ceiling, and fire sprinkler work under separate contracts.
• BCBS also provided the chiller slab and screen walls.

Client Note:

This project required installing new chilled water infrastructure into an active public building without disrupting county operations. Our team coordinated closely with Boulder County to sequence work safely around public hours, maintain building accessibility, and ensure that critical facility services remained uninterrupted.

Midlands Mechanical delivered a fully functional chilled water system, enabling Boulder County to modernize its HVAC platform, improve long-term cooling efficiency, and prepare the facility for future equipment upgrades.

Midlands Mechanical installed a nitrogen generation system at the Fiserv Data Center in Omaha, Nebraska. The system was designed to support the operation of large-scale dampers critical to facility ventilation and assisting processor cooling when required.

The job involved installing a membrane-style nitrogen generator, refrigerated dryer, compressed air system, and full copper piping to distribute nitrogen and air to control equipment. The system allows for improved response and reliability in the damper actuation network.

Scope of Work & Responsibilities:

Our work at Fiserv included:

• Nitrogen generator installation
• Refrigerated air dryer and pre-filter installation
• Compressed air piping
• High-purity nitrogen piping
• Valving, regulators, and inline filtration

Client Note:

This installation required close coordination with critical building systems. Our crew delivered a clean and functional install, tied directly into high-value infrastructure that keeps the data center operating efficiently and safely.
 

The International Quilt Studies Center was founded in 1997 after the University of Nebraska- Lincoln received a donation of over nine-hundred and fifty quilts. Before moving to its new state-of-the-art three-story, 37,000 square foot facility containing public viewing galleries, classroom and meeting spaces, a museum shop, conservation and research laboratory, virtual quilt gallery and a climate controlled storage area, the Center was located in a limited converted space of the Home Economics Building on East Campus. With the construction of the first “sustainable” green facility constructed on the UNL campus, the collection of quilts has grown to over two thousand three-hundred, with quilts from 24 different countries. The International Quilt Studies Center has also spawned a graduate program in textile history. This program is the only one of its kind in the world and encourages the study and appreciation of quilts as both aesthetic objects and as cultural artifacts whose beauty has significant importance to social and economic history.

To complete the construction of the 37,000 square foot facility an aggressive schedule was developed. During the project over 17,020 feet of sanitary, storm, domestic, and hydronic piping and associated equipment was installed by our workforce. Midland’s crews worked simultaneously onsite and in our fabrication shop to prefabricate every possible piping and hanger assembly in order to meet the construction deadline. Some system components installed are:

• (4) – Armstrong Series 4030 Base Mounted Pumps
• (2) – GTP Glycol Feed Systems
• (1) – AO Smith Cyclone BTH 250 Water Heater
• (3) – LES VW-100H-G Fire-tube Boilers
• (1) – McQuay GeneSys Air Cooled AGS 120CM/B Screw Compressor Chiller
• (3) – Armstrong HumidiClean Series HC-4100 Humidifiers
• (4) – McQuay Model TSH Fan Coil Units
• (4) – McQuay Model IM 217 Unit Heaters
• 614 Linear Feet of Vulcan Radiator Fin-Tube
