Project Description:
Midlands Mechanical provided all mechanical and plumbing systems for the new Lincoln Electric System (LES) Operations Center in Lincoln, Nebraska. This facility required a fully integrated HVAC, hydronic, and plumbing infrastructure to support office areas, fleet maintenance bays, heated parking structures, and specialized operational spaces.
Our work included installation of building water distribution systems, sanitary and storm drainage, domestic hot water systems, compressed air distribution, and a complete HVAC system tied into the District Energy Corporation (DEC) central plant. The project featured extensive coordination with DEC-supplied chilled water and heating hot water utilities, along with installation of sophisticated control components and a campus-wide Building Management System (BMS).
Scope of Work & Responsibilities:
Midlands Mechanical’s contracted scope included the full mechanical and plumbing package, covering specification divisions 22 and 23. Key responsibilities included:
Plumbing Systems (Division 22)
- Facility water distribution piping
- Domestic water piping, pumps, and specialties
- Sanitary waste and vent systems, including interceptors
- Storm drainage piping and specialties
- Installation of commercial water closets, lavatories, sinks, urinals, showers, wash fountains, emergency fixtures, and water coolers
- Domestic water heaters, heat exchangers, and water softening equipment
- Plumbing insulation and complete system identification
- Trench drains, catch basins, and sand interceptor pits, including coordination during slab pours
- Compressed air piping routed throughout the facilities
HVAC Systems (Division 23)
- Installation of heat transfer skid containing pumps, VFDs, expansion tanks, air/dirt separators, chemical and glycol feeders, gauges, and instrumentation to integrate with DEC heating hot water and chilled water systems
- Air handling units (AHUs) with VAV boxes serving the office areas
- Heat-only single-zone AHUs with energy recovery for heated parking and truck loading areas
- CO/NOx monitoring systems for enclosed parking environments
- In-floor radiant heating for vehicle repair bays
- Hydronic and electric unit heaters throughout the facility
- Belimo energy valves and pressure-independent control valves for coil energy management
- Full Building Management System (BMS) integration for HVAC and plumbing controls
General Construction Responsibilities
- Provide dust and exhaust control
- Daily cleanup and composite site cleanup participation
- Maintain streets and roadways free of debris during construction
- Temporary fall protection per project safety requirements
- Field verification of existing conditions
- Hoisting, lifts, scaffolding, layout, cutting/coring/sleeving, patching, and material handling
- Traffic control and delivery coordination
- (All scope elements derived from contract Exhibits A and narrative sections: e.g., plumbing details, HVAC narrative including radiant heat, AHUs, hydronics, and BMS, and general provisions.)
Client Note:
This project required seamless coordination with the District Energy Corporation (DEC) central utility plant and the LES operational environment. Our team successfully integrated complex hydronic and HVAC systems, maintaining strict performance, safety, and sequencing standards throughout construction. The result is a highly efficient mechanical infrastructure supporting LES’s mission-critical operations and long-term facility resilience.
