Slam dunk! Drop the puck! Light up the stage! Bring on
the elephants! The Pepsi Center—Denver's showpiece entertainment venue and one
of the premier sports arenas in the nation—is ready for action. The imposing,
high profile structure instantly became a landmark in the Central Platte
Valley, gateway to downtown Denver. It is the new home for the NBA's Denver
Nuggets, the NHL's Colorado Avalanche, and a total of as many as 200 events
each year ranging from concerts to circuses to family shows. The
675,000-square-foot, 7-level, round structure contains the sports/entertainment
arena with seating for up to 20,100 people, a 150,000-square-foot office
building, a 64,000-square-foot restaurant/specialty retail complex, a
5,000-square-foot convenience store/gas station, a full size NBA practice
court, state-of-the-art locker rooms, and cutting edge sound and lighting
systems. Pepsi Center sits on a fully landscaped, 52-acre site with parking and
elaborate site lighting. The arena itself has a 4.6-acre footprint.
When the lights go on, Pepsi Center will be flooded with
20,000 amps of electrical power. That's enough to supply a town of 3,500 for a
year—a total of 16.6 million watts (276,666 60-watt bulbs). Ludvik Electric was
honored to be "the electrical contractor of choice" and part of the
team that took the facility from a lofty vision to a spectacular reality. But
Pepsi Center was not your run-of-the-mill project.
The project began with an extensive MEP coordination
effort resulting in effective composite working drawings. Ludvik's fast-track
electrical installation included four 4000 amp services, one for each of the
four building quadrants, and two 1500 kW emergency generators. The Sports and
House Lighting System is fully microprocessor controlled with multi-tasking
capability that allows lighting to be preset for events throughout the year.
Approximately 120 miles of conduit and 569 miles of wire were installed, as
well as 280 panelboards and 13,000 fixtures. Also included was a sophisticated
card-access security system with CCTV monitoring, state-of-the-art locker rooms
with medical/therapy centers and video conferencing, a multimedia production
studio, press and media facilities, 17 concession stands, 41 public restrooms,
95 luxury suites on two levels, and a 60,000-pound 4-sided scoreboard—all in a
stadium measuring 132' from the event surface to the ceiling, the equivalent of
a 10-story building. In addition to the usual problems of "round"
building construction, it's obvious just from the scope of the job that the
highly specialized complex tossed a series of challenges Ludvik's way.
Coordination—Various systems and
structural components required that Ludvik work closely with other
subcontractors—concrete, steel, sound, computer, mechanical, media, etc. To
insure timely coordination of all electrical installations with other trades
and limit conflicts, Ludvik placed special emphasis on the availability of
accurate, up-to-date shop drawings on site. Layout drawings were updated weekly
and matched with work of other trades, especially relevant considering 28% of
the electrical work was affected by over 500 changes and additions necessary to
maintain the facility's state-of-the-art status. This ongoing effort enabled
Ludvik to work efficiently with other subs throughout the project and implement
many innovative techniques that resulted in a quality installation and a safer
work environment.
Precast &
Conduit—Precast concrete was used extensively in many areas, including seat
risers and the exterior facade. Ludvik had full-time crews at both the job site
and at the precast company to pre-fab conduit runs in conjunction with the
manufacture of concrete components. This kept much of the conduit hidden from
sight, meeting a design requirement for aesthetics and expediency.
Angles & Arcs—The curved walls,
seating areas and other arcs and angles in a round building always make
electrical layout and rough in difficult. Ludvik used AutoCad software to
mitigate the problem. Using grid lines and columns as reference points and
adding the information to drawings, laser technology was employed to easily and
precisely pinpoint locations for conduit runs, stub-ups, lights, panels,
sleeves and electrical devices throughout the building.
Trusses &
Catwalks—The ceiling of the arena required that a significant amount of
electrical work be executed 132' above the floor. The first problem was
interviewing and identifying electricians who didn't suffer from "high
anxiety." Once that obstacle was overcome, Ludvik was able to reduce both
the difficulty and the safety hazards of an installation at this height through
imagination and cooperation. The arena's catwalk and truss structure presented
an opportunity for thinking outside of the box. Working closely with the steel
subcontractor, Ludvik installed conduit on trusses after they were lifted off
the floor but before they were raised to the ceiling. A short conduit span at
the truss-to-structure connection point was all that needed to be accomplished
at the 132-foot elevation. This reduced the safety risk and raised the
installation efficiency so pulling of wire and cable could occur earlier in the
project through innovative teamwork. Once the catwalks were in place, remaining
conduit, cable tray, switchboards, transformers, sports lights, house lights
and other electrical work could be accomplished in a far safer environment.
Ludvik provided the steel subcontractor with all locations and weights by
lineal footage or piece of electrical equipment for structural calculations to
be completed. That's true teamwork!
Light Work—Actually, heavy
light work. The 268 Sterner Sports Lights in the arena weigh 130 pounds each
for a single unit and 220 pounds for a double unit. Each features a unique
luminaire shutter system to provide ideal lighting for sports or entertainment
events. To install these fixtures, Ludvik rigged a hoisting system fastened to
guardrails and structural cross members, allowing the light fixtures to be
hoisted from the catwalk staging platform into the permanent mounting position,
again addressing efficiency and safety.
More On Safety—In addition to
extreme heights, other factors that put special emphasis on safety included
colorless, odorless machinery fumes that could build up in the dome, the
concentration of trades, the schedule duration, and use of large equipment.
Each new Ludvik worker attended two orientations prior to starting work. Fall
protection, lift training, special hazard recognition and other safety issues
were discussed at weekly safety meetings. A weekly safety audit was conducted
by Ludvik's Safety Director. Ludvik's crew of 124 workers at the peak, plus two
electrical subcontractors working under Ludvik's direction spent 185,000
man-hours over 18 months at Pepsi Center with zero lost time due to accident or
injury.
With a well-conceived game plan in place, this team executed to perfection. Pepsi Center is a winner.
