- Title: Remove current chain link fence and build mammalian pest-proof fence at the Honouliuli Refuge unit of the Pearl Harbor National Wildlife Refuge The U.S. Fish and Wildlife Service has a requirement to remove current degraded chain link fencing surrounding the Honouliuli refuge unit and dispose off site and to build an approximately 3,500 foot long mammalian pest-proof fence which, upon completion, will be an effective barrier to the entrance of all non-flying mammalian pests. Construction period is anticipated to be January 2017 through June 2018. Project is unrestricted and is open to any size business. Applicable NAICS code is 238990. SITE VISIT: If interested in attending a site visit, contractors can meet on Tuesday, December 27, 2016 at 10 AM in the parking lot of the Asing Community Park located at 91-1450 Renton Rd, Ewa Beach, HI 96706. George Fisher (George-fisher@fws.gov) or Joseph Schwagerl (joseph_schwagerl@fws.gov) will meet contractors at the parking lot so they can follow them to the site nearby. QUESTIONS FROM SITE VISIT: Questions from the site visit shall be directed to Karl Lautzenheiser at karl_lautzenheiser@fws.gov by close of business on Thursday, December 29, 2016. Questions will be consolidated and answers provided by issuance of an amendment to FedBizOpps. A complete description of the fence design can be found below in Fence Construction Specifications as follows: LOCATION CONSIDERATIONS The fence site at Honouliuli is located in the town of Ewa and is situated on Pearl Harbor (see figure 1). Access to the site will be through a locked gate on a dirt access road. This road is made of gravel, and dirt, and can become muddy and soft in places after heavy rain. The proposed project area is generally flat and has a mostly sandy substrate. The northern boundary of the refuge lies along the shore of Pearl Harbor and includes a strand of red mangrove forest. This area will become more subject to inundation associated with sea level rise. This shoreline area will not be fenced. The fence will extend out into the water approximately 10 meters on each upland end of the fence. The Honouliuli unit consists of two separate ponds. The smaller Pond A on the west side is approximately 5.2 acres and the larger Pond B is approximately 14.1 acres. The predator- proof fence will follow the existing perimeter fence, except along the northern boundary. There is a ditch that extends inland approximately 1,128 feet from the Pearl Harbor shoreline into the refuge (see Fig. 2). It is approximately 4 meters wide and usually contains water. The Predator-proof fence will not affect this canal. There are trees and shrubs growing along the current boundary fence. Vegetation removal will be required including removal of all trees and shrubs within 4 meters of the outside of the fence. FENCE CONSTRUCTION SPECIFICATIONS The fence design, materials, and construction specifications are described in detail below. These are based on the specifications required to completely exclude the mammal species found at Honouliuli, as determined by extensive research in New Zealand and trials in Hawaii (Day and MacGibbon 2002, Burgett et al. 2007), and previous experience constructing predator fences in Hawaii (Young et al. 2012, Young et al. 2013). Fence dimensions, angles, clearance, and abutments 1.Height. The fence should stand no less than 1.9 meters high to prevent feral cats from jumping over it. This height is measured from a point one meter out from the base of the fence ¿ representing the likely jumping position of a cat ¿ vertically to the top of the hood. 2.Angles. No exterior corner should be sharper than 45 degrees off the line of the adjacent fence sections (see diagram below) to prevent animals gaining access to the top of the fence by jumping from one section to another. 3.The area immediately outside of the fence (i.e., the pest side) should be completely free of any objects, structures, or vegetation >30 cm in height within 4 meters of the fence to prevent animals from jumping to the top of the fence or over it. 4.Abutting fences. Where another fence adjoins the pest proof fence on the outside (i.e. pest side), the pest fence must be 1.9 meters taller than the other fence to retain the required clearance. (For example, if an abutting fence stands 1.2 meters off the ground, the pest fence must be extended to a height of no less than 3.1 meters off the ground. 5.Unmovable trees and structures. If any trees or other objects on the outside of the fence must remain within 4 meters of the fence, those trees and structures should be banded with materials that prevent pests from climbing them, and the banded trees should not be in contact or within 4 meters of other trees on the outside of the fence that are not also banded. Fence materials All materials, including the mesh, hood, and screws and other hardware, will be made of stainless steel, except the fence posts, which will be made of wood treated against termites and rot. Wooden fence posts are recommended at this site because their larger diameter will provide a more secure footing in the sandy soil. Metal fence posts are much narrower and might shift in the sand more easily. All materials will be tested by an independent lab to verify that they meet the desired specifications. 1.Posts. The fence posts will be made of treated wood and will be 2.7 meters long and ~12.7 cm (~5in) in diameter and full round in shape. Posts will be placed in holes 0.7 meters deep and spaced 2 m apart. 2.Braces. Stainless steel braces, or stays, will be placed on every fourth post over the entire length of the fence to provide increased strength against wind. All braces must be attached on the inside of the fence, so that animals cannot climb up them. 3.Mesh and skirt. The face of the fence and the horizontal skirt extending out from the base of the fence will be made of marine-grade 316 stainless steel mesh. The mesh will consist of flexible rolls that are 2.3 m tall and up to 10 meters long, so that the face and mesh are seamless. The aperture dimension of the mesh will be no larger than 7 mm in order to exclude mice. The mesh will be attached to the posts and post framework using stainless steel hardware. 4.Hood. The hood will be made of 304 grade stainless steel, and will be provided in the shape outlined in Exhibit E with the exception of the length which will be 4.1m long sections (vs 3m outlined in Exhibit E). The hood will be attached with a stainless steel bracket to each post, and attached to the frame using stainless steel hardware. The smooth surface, slope, and shape of the hood prevent animals from gaining traction and climbing to the top of the fence. Please see Exhibit E for precise measurements of hood holes and dimensions (with the exception of the modified 4.1m length). 5.Water culverts. One culvert are necessary at this site because there is little slope, the soil is sandy and very porous, and there is no surface slow of water. 6. Fasteners. The Contractor will provide all fasteners necessary to attach the fence components to each other, including solder for joining hood sections. All fasteners and solder must be stainless steel to avoid electrolysis. Fence construction specifications 1.The fence must be constructed in such a way that there are no gaps wider than 7 mm along more than one dimension between the inside and outside of the fence. This specification should be inspected in the following parts of the fence: ¿All joints between sections of the mesh forming the face of the fence. ¿The junction between the mesh and the hood at the top of the fence. ¿The joints between each hood section at each post and at each corner and bend in the fence. 2.Skirt. The mesh skirt (the portion of the mesh that extends horizontally out from the base of the fence) should: ¿Extend at least 35 cm out from the fence base. ¿Be covered with soil to a depth of 10 cm (4 inches) so it is not visible (see Figure 2 ¿Be secured to the ground with stakes or pegs in any sloped areas. ¿Not be scoured out or tunneled under in any way. 3.All staples, rivets, screws, and pins should be tightly seated so that mesh or hood sections cannot flap to create gaps greater than 7mm; all fastening hardware must be of the same type of metal as the mesh. 4.Hood attachment. The rivets or screws used to attach the hood to the brackets should be inserted from the underside, so that only a small nub, and not the head of the screw or rivet, is present on the top of the hood, in order to reduce traction available to animals that somehow reach the top of the hood. Access gate. Gate providing access to the fenced area must: 1.Be designed and attached to the body of the fence in a pest proof manner, i.e., with no gaps greater than 7mm (1/4 inch) along more than one dimension when the gate is closed and latched. 2.Have either a mesh skirt or a solid concrete footing beneath the gate entrance that extends out from the gate by no less than 35 cm. 3.Have a latch or other means by which the gate can be locked or rendered un-openable from the outside. Earthworks 1.A fence platform consisting of a gentle mound (when viewed in cross-section) will be formed so that drainage water cannot pass through the line of the fence. 2.The earthworks and substrate adjacent to the fence should not have any channels, tunnels, or gaps greater than 7 mm in more than one dimension that extend under the fence from the outside to the inside. 3.The ground conditions adjacent to the fence should be such that there is no risk of slumping or erosion that may cause damage to the fence or compromise any of the standards listed above. Basis for award will be ¿Lowest-Priced, Technically- Acceptable. ¿ The lowest priced offeror will receive the award if considered to be technically acceptable. If not considered technically acceptable, the next lowest priced offeror will be evaluated until the lowest priced offeror is identified that is considered technically acceptable to receive the award. To be considered technically acceptable, the offeror must submit the following information with their proposal for evaluation: 1.Past Performance: List past projects performed that are similar in nature to the Statement of Work with current points of contact and phone numbers (not-to-exceed three pages). The contractor is solely responsible for the accuracy of this information as the Government will not pursue incorrect contact data. 2.Technical capability of the item offered to meet the Government requirement (not-to-exceed 3 pages). List experience in building predator proof fences, the locations and references for jobs completed. If no experience in building predator proof fences, then a description of experience building conservation fences in Hawaii along with three references (including contact information); and 3.Price (no page limit): A price estimate that includes all costs associated with the items listed below; please break down costs into labor and materials categories: a)Labor and machinery/tools required for construction of the 3,500 foot long Mammalian Pest Proof Fence at Honouliuli. Note that Davis-Bacon wages are required for this project. b)Stainless steel fasteners, solder and cement necessary for construction of (note that this is 50m longer than the fence length so that materials for repairs are left on. The cost of these materials should include shipping and any taxes, such as local US/Hawaiian taxes, employee/Contractor taxes, GET etc.).
