• T-Mobile provides wireless voice, messaging and data service to over 45 million customers in the U.S. Its nationwide network reaches 96% of Americans. Their Wayne, NJ facility was upgraded to provide emergency backup to its growing customer base. • A new 1,200 SF building had been constructed specifically to house the new backup systems. Since all the these units would need to tie-in to the existing system, our work took place both in the new building and the existing office as well as the courtyard connecting the facilities. A 75 kVA transformer with associated power panels, lighting, power, security system, fuel oil controls, lighting protection and a grounding system were all installed in the new structure. The new emergency backup includes two 2-megawatt diesel generators, a 6,000 amp synchronizing switchboard and a 3,000 amp automatic maintenance bypass switch. • Duct banks were installed consisting of 19,000 LF of conduit, 43,000 LF of feeder cable terminations and 25,000 LF of control and miscellaneous power cable. A unique challenge occurred during the duct bank installation: the uneven, sloping nature of the grounds required heating and bending the PVC pipe to ensure a proper fit, thus enabling complete integration of the old and new systems. Our close coordination with the excavating contractor allowed the project to continue without disruption.
