4 Question: How will we find the service lines for the homes that do not have visible meter boxes on Sheet 16, Subdivisions Riverside, Fairway Lakes, Bay ridge, and Sheet 17 Eagle Trace? Answer: It will be the contractors responsibility to soft dig to locate all service lines. Record drawings may be made available. Question: I have reviewed the plans for the subject project and am requesting that Fusible PVC pipe be allowed in lieu of HDPE for the horizontal directional drill elements. Use of Fusible PVC will provide the following upfront cost advantages as well as long term performance advantages: 1. Since 6 HDPE is connecting to 4 PVC and 10 HDPE is connecting to 8 PVC, Fusible PVC can be 4 connecting to 4 PVC and 8 connecting to 8 PVC since it has the same ID for a given nominal size pipe as B&S PVC. With no need to increase the HDD pipe a size, then the bore hole can be smaller, the fittings don t require fused adapters (FPVC accepts mechanical fittings directly just like B&S PVC), and the pipe weight drops. All this allows for a less expensive HDD installed cost. 2. Utilizing Fusible PVC for the HDD elements results in the entire pipeline being the same thermoplastic pipe. PVC has been demonstrated by decades of use in potable and reclaim water systems to be resistant to oxidative attack by disinfectant compounds (example chlorine, hypochlorite, chlorine dioxide) commonly used to combat biological growth and pathogens. HDPE has been proven by numerous third party research studies (reference following link - to be susceptible to oxidative attack by the disinfectants compounds under pressure applications of water/reclaim water distribution. Answer: Per Charlotte County Detail G-08-DB, Page 23, Typical Directional Bore on Sheet 30 of the plans, Fusible PVC is an acceptable alternative to HDPE. Below is a write-up from Charlotte County Utilities Standard Specifications (January 1, 2008). Page 4 of 5
