Client: Palm Beach County Roadway Division
Project Description: Construction of two (2) buildings with a total of 350 rental apartments and 1,280 square feet of office space.
The Palm Beach County Roadway Division was proposing to expand Central Boulevard for approximately 1.5 miles to a 5-lane/4-lane roadway. The scope of work included bridge widening, milling and resurfacing. HSQ Group prepared construction plans and specifications for the county. An environmental impact evaluation, permitting, signing and pavement markings and a right-of-way study report was also required.
As part of the proposed roadway improvements, Palm Beach County agreed with the Loxahatchee River District to replace the existing 10″ sewage force main and 16″ reclaimed water main aerial/bridge crossings. The existing mains were each located on opposite sides of the bridge crossing over the South Florida Water Management District C-18 Canal. To avoid having the existing 16″ reclaimed water main out of service for an extended period of time, it was decided to design both new aerial bridge crossings on the same side of the bridge. The sewage flows within the existing force main were able to be re-routed temporarily. Therefore, a new 12″ D.I.P. force main and 16″ D.I.P. reclaimed water main were designed to be installed under the new bridge slab widening. Outside of the bridge limits, a portion of the new force main installation required a directional bore process under the existing roadway.
