Land Mobile Radio
The Big Lift
HICAPS was selected as the contractor to relocate the Enterprise Land Mobile Radio (ELMR) systemf rom its original 90-foot location atop Building A-128 to its permanent location 10 stories high on the rooftop of BuildingW-143 at the Naval Base in Norfolk, Virginia.
The ELMR relocation was a significant portion of a $2.5 million site improvement project to demolish the obsolete building
A-128 and create much-needed parking near the Bachelor Officers’Quarters. Before the demolition could be completed, a new l00-foot tower had to be erected and the 34,000-lb. communications shelter contai ning the ELMR system had to be moved to its new location several blocks away.
HICAPS’ Project Managers,Tom Smithey and Thom Bradley, worked in partnership with Norfolk-based communications contractor CR Services Inc. and the Chesapeake, Virginia-based prime contractor, SYNCON, LLC to successfully move the mission-critical ELMR and its sensitive equipment from its original location to its new home.
The project team worked to design and install a new grounding system that would provide lightning protection for the ELMR at its new location. 1he new 100-foot ELMR tower was successfully erected at its new home overlooking the Elizabeth River in April of this year.The bigger challenge came in August when the 34,000-lb. communications shelter was lifted off Bui lding A-128 and transported approximately three-quarters of a mile to its permanenr location on Building W-143. Using one of W.O. Gru bb’s largest cranes-with a capacity of 365 tons and a reach of more than 200 feet- the fully loaded communications shelter was carefully lifted and transported to its new home, and was back online in five days.
