BSU Old 41 Utility Relocates Phase 2

RWA provided the design, permitting, bidding, and construction phase services for multiple sanitary sewer force main and water main relocations necessitated by improvements associated with the Old 41 Road Widening Project being constructed by the City of Bonita Springs. Sanitary force mains and water mains of various sizes were located within existing rights-of-way and easements along Old 41 Road from Rosemary Drive to U.S. 41. A major component of the utility relocation work was coordination with the roadway design engineer, as well as the proposed utility relocation plans of the private utilities within the existing right-of-way. A preliminary review of the 60 percent roadway design plans indicated a total of twenty significant water main and force main relocations. In addition, approximately 28 minor relocations were verified at specific locations during the design process through the use of subsurface utility locating. The project involved the relocation of more than 11,000 feet of force mains and water mains ranging in size from 8” through 24”.  This project included coordination with the City of Bonita Springs Old 41 Road project design engineer, construction manager, and Seminole Gulf Coast Railroad. 

Spring Creek Village Water & Sewer Study

RWA performed a water and sewer study that consisted of preparing proposed alternatives for replacing the existing water and sewer facilities within Spring Creek Village. The study consisted of assembling existing as-built water and sewer plans, reviewing existing studies and agreements, and obtaining copies of existing permits and consent orders.  In addition, the study developed typical cross sections, explored three alternatives for the sanitary system, minimizing sizes of gravity, force and vacuum mains, developed a preliminary plan for potable water main replacement,  reviewed restrictions for tying into the existing sanitary sewer system, developed an opinion of probable cost for feasible sewer alternatives and water mains, incorporated soil boring information, identified surveying needs, and developed preliminary and final construction budgets and schedules.  The study required significant coordination with a geotechnical engineer in developing feasible alternatives for the sanitary sewer system replacement. Gravity, low pressure force main, and vacuum system options were reviewed.  An opinion of probable cost was developed for each alternative and used for basis of assessments.  The project involved conceptual planning of 8,000 feet of water main and gravity sanitary sewer.

Old 41 Shangrila Road Effluent Main & Force Main

RWA provided the design, permitting, bidding, and construction phase services for a new 30" ductile iron pipe effluent main, 8" PVC force main and a 4” communication conduit from the West Water Reclamation Facility (WWRF) south along Old 41 Road to Shangrila Road, running east and crossing I-75 to the East Water Reclamation Facility (EWRF). Coordination was necessary with the roadway engineers designing the Old 41 Road widening, Shangrila Road improvements, Three Oaks Parkway, the I-75 widening project, Seminole Gulf Railroad, and the consultant designing and building the EWRF.  The total length of the project was 19,000 feet including the design of directional bores in two different locations.  The longest of the bores was 600 feet long under I-75 involving three separate bores, one for each main; the 30” HDPE effluent main inside a 42” HDPE casing, 8” HDPE force main inside a 16” HDPE casing, and 4” HDPE communication line inside an 8” HDPE casing. The I-75 directional bores involved coordination with FDOT and the contractor constructing the EWRF.  A second directional bore was 400 feet long under Old 41 Road and within the existing WWRF grounds involving three separate bores, one for each main; the 30” HDPE effluent main, 8” HDPE force main, and 4” HDPE communication line.  The Old 41 Road directional bores involved coordination with Seminole Gulf Railroad and the City of Bonita Springs.
