MacDonald-Miller’s emphasis is in design-build construction. Our account executives, or sales force, work directly with owners and their design consultants to develop system concepts for buildings’ program requirements. Once the design is complete, and the Mechanical/Plumbing drawings are completed by Engineering, there are still a few more steps before each trade goes out and installs.
Detailing is the process of transforming the Mechanical/Plumbing design from our Engineering team into a detailed 3D model that is constructable and coordinated with other trades. This model is used to generate detailed drawings, material lists and fabrication files to allow the shop and field to fabricate and install the pipe and ductwork.
One of the main elements of this process is clash detection, which involves taking the many models of everything on the project including steel, walls, duct, pipe, electrical, fire protection, lights and even kitchen equipment and identifying impacts to confirm that everything has a place to go. This process allows issues to be identified in the office months in advance, rather than out onsite while trying to get everything installed.
Our sheet metal detailers crushed it on a recent project that consisted of building four 5-story office buildings. In total, these buildings have more than 1,434 terminal units and 34 hoods filling up the kitchen spaces. They are largely supported by a Dedicated Outside Air System (DOAS) utilizing sensible cooling units to provide energy efficient cooling/heating to the offices.
For this project, MacMiller Detailing performed the sheet metal and MEP coordination scopes. With four buildings operating on overlapping schedules, MacMiller was running 2-5 clash reports a week covering 1-3 buildings at a time. This led to hundreds of clashes being identified and resolved on a weekly basis while juggling the modeling for the upcoming floors.
Eddie Markwardt led the detailing front for all buildings on this project. This included leading a team of 11 detailers to complete the modeling, coordination, and fabrication deliverables throughout its life cycle. In addition to traditional MEP Clash Detection coordination, Eddie led his team in a special lighting coordination, clashing, and modifying unit layout around lights added after signoff on each of the office floors. This step ensures that all code-based clearances were achieved and allows building maintenance to be a breeze in the long term.
In the words of Joe Daniels, “From the Trimble support at the beginning of the project, to the kitchen hood support details during the heat of the battle as well as the GRD & Flex reports during trim time… our detailing team ROCKED it!”
