30. Question: It is unclear from the language in this paragraph what labor and/or materials will be included in the 10‐year warranty coverage. Please clarify if the warranty covers only the synthetic turf or if it covers the labor and materials supplied to construct the subgrade and draining gravel blanket as well, or any other portions of work incidental to the contract. Answer: The warranty is required for the project. 31. Question: A G‐max maximum of 110 is specified at time of substantial completion. Normally the G‐max of the synthetic turf field will degrade over the life of the field. Please clarify what the maximum allowable G‐max over the 10‐year life of the warranty. Answer: Bidders may include information on the expected degradation of the G‐max value over the warranty period. 32. Question: The technical specifications do not specify a drainage pipe in conjunction with the 6” of “draining gravel blanket”. Normally the design would call for a perforated collector pipe at the edge of the synthetic turf area to collect the water that drains through the gravel layer. This pipe would be connected to an existing storm water system utility. If a perimeter pipe is not required, the existing subgrade material under the synthetic turf area would need to be quite porous to allow water to drain away from the underside of the synthetic turf. If there is not a collector pipe and the subgrade layer is not porous, when the “draining gravel blanket” becomes fully charged with water in a heavy rain the synthetic turf rubber infill will float and be washed away with any surface drainage. Please clarify the following: Will a perimeter collector pipe be required for each site? Is there an existing storm water utility system at each site? If so, please provide the location and depth of exiting storm water utility system (depth to the invert pipe outlet from the ground surface). Answer: This is a turnkey project. All required plans necessary to obtain all applicable permits are required to be prepared by the bidder including appropriate details for installation. The design prepared by the contractor and submitted to the City for permits must address drainage considerations. Storm drainage as‐built are not available for either site however, record drawings that may provide additional guidance are attached hereto. 33. Question: The technical specifications do not provide a specification for the Shock Pad. Please clarify which pre‐manufactured shock pads will be acceptable for this project. Answer: Bidder shall specify the shock pad proposed to meet G‐max requirements contained in the RFP. 34. Question: The face weight (weight of the synthetic turf fiber per square yard) of the synthetic turf product is not specified. The face weight of differing synthetic turf product is highly variable and will greatly impact the longevity and playability of the synthetic turf surface. Answer: Bidders need to consider warranty requirements regarding the longevity of the product and installation.
