Full Service

Williams + Harvey’s is a vertically integrated mechanical engineering and construction company, which allows us to operate differently than a traditional engineering firm.

We offer services for the full life cycle of a building, from design and engineering to HVAC, hydronics and plumbing installation. Our services also include custom sheet metal fabrication, oxygen systems, and maintenance and service.

We Design What Is Built

Our engineering services are unique because of our focus on the constructability of the design. By sharing information across departments, we utilize the feedback we get from the field to close the gap between design and construction. Our goal is to make the installation go as smoothly as possible, so we not only design with fabrication in mind, but we also provide more detailed drawings that help to reduce the work of the contractor. When you see our drawings, you see the difference.

We utilize Laser Scanning to bridge the gap from design to construction. Having accurate as-builts throughout the construction process allows us to coordinate all our ductwork and piping from the office. The additional information provided by the scan creates the environment to model our design at a higher level of detail. We are able to then pre-fabricate the bulk of our installation which reduces cost, saves labor time, and reduces project schedule.

Laser Scanning Services

As-Built Verification

Laser scanning as-built conditions is easy with the Leica RTC360. In approximately 1.5 minutes the laser scanner scans and photographs the space. The precision of the laser scanner ensures accuracy on reconstruction of as-built conditions and documentation of existing conditions.

Point Cloud to Revit

The laser scanned data is capable of being linked into Revit for as-built reconstruction, and all imagery is maintained for future referencing needs. The imagery and content is accurate within an 1/8 of an inch. The documentation and point cloud capabilities of the Leica RTC360 eliminate the need for traditional hand measuring.

Engineered Prefabricated Mechanical Room Pods

Prefabrication is the heart of our beliefs on mechanical and plumbing contracting.

Working closely with our Engineering division and their design software capabilities, we ensure that our installations fit precisely and are fabricated with the highest level of quality and care. When schedules are fast, prefabrication allows our team to produce large quantities of product and assemblies offsite in our warehouses, most of the time prior to the building being ready for mechanical and plumbing installation.

All fabrication operations are supervised by our full time division managers. With separate warehouses available for black pipe, copper, PVC and stainless steel, our fabrication shops can handle any project thrown at them, at any time.

Carbon Neutral Homes

We believe in the importance of green design.

Building efficiency is one of the primary ways we can reduce our carbon footprint. Our engineering team is experienced in designing high-efficiency systems ranging from air conditioning and heating to greywater recycling and rainwater collection.
