Description

As part of the angler access portion of the Provo River Restoration Project, the Mitigation Commission has committed to construct a trail and boardwalk system from the Cottonwood Canyon Access Site (existing) to the Jordanelle Dam Access Site (under construction) to facilitate angler travel adjacent to the riverine corridor. This trail and boardwalk system is needed to replace the existing trail/dirt road on top of the river dike, which will be removed as part of the Provo River Restoration Project. The existing road/trail receives heavy use by anglers, hikers and bird watchers, and the replacement system is needed to guide the public through the area to minimize the proliferation of trails through areas containing sensitive wildlife habitats. Areas to be crossed by the trail/boardwalk system are open-water (ponds) or wet meadow/emergent marsh wetlands, wet grassy areas, (see attached map). A means of transporting people through these areas with minimal disturbance is needed. Extensive consultation with landscape designers, public users and agency personnel has identified that the means of crossing the wet areas must be accomplished with: 1. Minimal disturbance during construction. This means that heavy equipment and construction workers should be kept out of the wet areas to the extent possible; wet cement, which is toxic to aquatic life while uncured, shall not be introduced into aquatic sites. 2. Minimal operation and maintenance. Operation and maintenance that would require repetitive entry into the aquatic sites to repair, replace, or refurbish structures should be avoided or minimized. Helical piers are needed to be installed in two areas. The north segment of boardwalk for which the helical piers provide the foundation, is 420 feet in length. The south segment of boardwalk is 500 feet in length (see attached drawing). Allowing for adjustments in the field up to 200 piers are anticipated under this contract. The work shall progress as follows: A. Two piers shall be placed using equipment weighing 5,000 pounds or less. The equipment shall be able to reach the required distance to place the next set of helical piers without leaving the previously installed decking. B. Prefabricated decking will be supplied and placed on top of the newly placed pair of piers by Government forces. C. The Contractor has the option of either standing by while the prefabricated deck is being placed by Government forces or placing piers in areas where decking is not required to be in place prior to placing the next pair of piers. D. Drive over the newly placed decking and place another pair of piers. It is in the Contractor's best interest to make good use of time by placing piers in areas that do not require decking for access while decking is being placed: however, once a decking section has been installed, the Contractor shall make every effort to place the next set of piers to facilitate continued placement of decking. It is estimated that 35 to 45 percent of the piers can be placed without any decking in place. The piers that are placed without decking will require some "mats" to distribute the load of the equipment over the wet grassy areas. Mats may consist of 3/4-inch thick plywood sheets or any other non-toxic material that will distribute load. The maximum loading on each pier will be 3.3 Kips based on a live loading of 100 pounds per square foot of boardwalk and a dead loading of 10 pounds per square foot of boardwalk. Each pier shall be capable of bearing a minimum 6.6 Kips of load given a safety factor of 2. The piers shall be engineered by a registered professional engineer. The piers shall be engineered for wetland types of soils. The soil types consist of mostly clay and gravel. Each pier shall come with a bracket (1/4- inch minimum plate thickness) capable of receiving two 2 x 8 wood members and shall have a hot dipped galvanized finish (both bracket and pier). This is a commercial item. Simplified Acquisition Procedures apply. Small Business Set-aside. Please call Nancy Biddinger for a copy of solicitation @ (801) 379-1119.
