MEP 3D Coordination at PACCAR‣ 99% of beam penetrations were shopfabricated as a result of earlycoordination.• Estimated savings = $120,000• 242 penetrations added• 127 modified size or location‣ <strong>Building</strong> architecture preserved bymaintaining ceiling heights and keepingMEP hidden despite a great deal ofopen structure. LMN Architects,structural teams, and the M/E designteam attended meetings as needed andcollaborated with Sellen to resolveissues early and avoid costly changeslater in construction.DRBF Annual MeetingSeptember 23, 2011
