DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The Campground was original constructed in 1956, with100 camping sites it has undergone numerous changes and updates in the subsequent years. Including the installation of multiple comfort stations. Due to the elevation of the campground in relation to the wastewater treatment it was necessary to install lift stations to facilitate moving the waste out of the campground to the proper area. The original lift stations were installed in 1999 and then quantities and pumps were updated in 2005. In 2012 the Campground received a new Shower comfort station requiring the update or the wastewater lines and lift stations again.

The goal of this project is to match the existing salient characteristics of all existing materials and replace the necessary valves and hardware in two of the lift station valve vaults within the Cedar Pass Campground. The size of the piping, gate valves, check valves and duckbilled check valve are listed in the Bid Schedule. One of the stations is along the Butte Loop of the campground and the other is at the comfort station for the Group Loop. The valves received damage due to being flooded with wastewater and its highly corrosive nature. The current valves are inoperable at this time causing a risk for the visitors and park staff at these locations.

1.2 Work Covered by the Contract Documents:

A. Project Location: Badlands National Park, Interior South Dakota. 20633 SD HWY 377, Interior SD 57750

B. Work consists of: This Project would consist of Contractor Removing old inoperable valves and subsequent hardware at two lift stations within the Cedar Pass Camp Ground at the Badlands National Park. All valves and hardware removed from the valve pits, will be disposed of off of park property by the contractor. The valve pit, remaining pipe and hardware within the pit will then be cleaned, all fluids will be removed from the pit and properly disposed of. The contractor will then be supplying and installing four new, four-inch gate valves, along with their new support frames, check valves (4), Stainless Steel Hardware (including but not limited to: bolts, nuts, washers, lock washers, and gaskets), and piping (including but not limited to: flanges, 90-degree elbows and cross pieces) necessary for operations. All valves and hardware will be compatible with the current system existing in the valve pits. The contractor will also install all the appropriate attachments including, new floats, new blind flanges, and gaskets in association with the gate valves and new check valves to ensure that the system operates at appropriate levels. After all parts are installed, the contractor will then do an operations test and pressure test to insure proper operation. At the time of test the park will provide a USRO (Utility Systems Repairing-Operating) personnel and Contracting Officer’s Representative to inspect and ensure satisfactory operation.

1. Butte Loop Lift Station: Work will consist of Removing the existing floats from the wet well.

Washing out both sections of the lift station vault (the park will provide water for cleaning of vault). Installation of new floats, reconnecting them to the control station, and then calibration as needed. Remove existing check valves, flanges, and associated hardware from the valve pit of the lift station. Instating of new valves, flanges, hardware and supports, in the valve pit. System will be tested to ensure proper function before it is signed off as complete. (See Images B.1 and B.2)

2. Group Loop Lift Station: Work will consist of removing the existing floats from the wet well.

Washing out both sections of the lift station vault (the park will provide water for cleaning of the vault). Installation of new floats, reconnecting them to the control station and then calibration as needed. Install a new duck-billed check valve (Tideflex or equal) in the wet well drain line from

Page | 4 the valve vault to prevent backflow of wastewater into the valve vault. Remove existing check valves, gate valves, flanges, elbows, cross and associated hardware. Install new gate valves, check valves, elbows, cross, flanges, supports, and hardware in the valve pit. System will be tested to ensure proper function before it is signed off as complete. (See Images C.1 and C.2)

The contractor will then be suppling and installing four new, four-inch gate valves, along with their new support frames, check valves (4), Stainless Steel Hardware (including but not limited to: bolts, nuts, washers, lock washers, and gaskets), and piping (including but not limited to: flanges, 90-degree elbows and cross pieces) necessary for operations. All valves and hardware will be compatible with the current system existing in the valve pits. The contractor will also install all the appropriate attachments including, new floats, new blind flanges, and gaskets in association with the gate valves and new check valves to ensure that the system operates at appropriate levels. After all parts are installed, the contractor will then do an operations test and pressure test to insure proper operation. At the time of test the park will provide a USRO (Utility Systems Repairing- Operating) personnel and COR to inspect and ensure satisfactory operation.
