certainty that it wasn’t going to cost them more than they
were willing to invest.”
Premier Electrical and Rick Electric came on later in the
process but before design documents were complete, which
enabled them to provide feedback on constructability and cost.
“That helped a great deal to have those partners be part of
the design process from very early on, which helped with continuity start to finish,” Hendrickson said.
Facing challenges together
The design of the building presented particular challenges for
the electrical contractors (ECs).
“It’s a large building and has a lot of unique architectural
features, including large atriums in areas and angled walls,
which made it difficult to wire the building to get from A to
B,” Harmon said. “We couldn’t just go normally in a straight
line. We were able to put a lot of wiring below the ground-
floor slabs and conduit in the slabs. The feeders to the power
panels run primarily below the ground-floor slab, then verti-
cally rather than from distribution to the lighting panels out on
the floor. The runs were predominantly vertical from the floor
slab or below it. We had to find areas we could run vertically
in walls and chases.
“We used [building information modeling] for coordination
with other trades and the Trimble system to lay out the con-
crete slab and underground because of the post-tension cabling
system and the size of the building. With it we could take our
CAD drawings and locate points on the job site. We didn’t have
to go out there and measure from the grid lines with a tape
measure. Once you get the Trimble set up to a point on the
architectural/electrical/mechanical drawings, you can use that
to find any other point,” he said.
Kent Voelker, general foreman, Premier Electrical, was
happy with how the schedule played out.
“The building schedule was not the usual to save time, and
it worked,” he said. “We had different crews doing different
things at the same time. We were already working on the east
building, roughing in walls, pulling branch wire while they
were still pouring concrete. Later in the job, we had people
still roughing in walls, other people following the Sheetrock
[or] the painter and putting in receptacle devices and finishing,
and others roughing in walls in other parts of the building.”
Having a construction manager on board allows for more
cost certainty than a traditional approach where someone would
design it, contractors would bid it and then build it.
