Services
Mechanical Services
Our mechanical contracting services encompass complete HVAC system design and installation for commercial and industrial buildings. With LEED-certified engineers and advanced BIM technology, we deliver energy-efficient solutions that reduce operational costs while maintaining optimal indoor environments. Our prefabrication capabilities ensure precise system components that minimize field adjustments and accelerate project timelines.
Design-Build Projects
Our design-build methodology combines architectural vision with mechanical expertise to streamline project delivery. By maintaining control from concept through construction, we ensure design integrity while optimizing cost efficiency. This approach reduces project timelines by up to 30% through concurrent design and construction phases, with guaranteed code compliance and constructability assessments.
Fuel Oil Systems
We design and install comprehensive fuel oil systems for backup power generation and industrial applications. Our capabilities include above-ground and underground storage solutions, double-contained piping systems, and regulatory-compliant permitting. With specialized CAD support and certified installation teams, we ensure safe, leak-proof systems that meet strict environmental standards for both new construction and system retrofits.
Prefabrication Services
Our in-house prefabrication facilities produce precision mechanical components in controlled environments, reducing field labor by 40%. Using 3D laser scanning and BIM coordination, we create assembly-line quality components that minimize waste and improve safety. This approach accelerates project schedules while maintaining dimensional accuracy to within 1/16th of an inch.
BIM Engineering
Our BIM department employs 70+ certified operators using Revit and Navisworks to create detailed 3D project models. This technology enables clash detection, constructability analysis, and laser-accurate layouts that reduce rework by 25%. We provide owners with as-built digital twins for facility maintenance, ensuring long-term operational efficiency through our Bluebeam Studio integration.
