About this file
This addendum to the solicitation involves replacing a failed 2-inch carrier pipe and 4-inch casing pipe at the Elk Mountain campground in Wind Cave National Park. The project requires furnishing and installing approximately 438 lineal feet of HDPE DR11 200 psi pressure pipe for the carrier and casing, along with concrete patching of areas disturbed by the work including a road crossing, parking lot, and walking path. The bid schedule, technical specifications, and standard details provide requirements for the HDPE pipe, fittings, connection methods, concrete patching, crushed gravel subgrade, and rebar to be used. A location map shows the project area and plan and profile drawings depict the existing conditions. The work is being conducted by the National Park Service Midwest Region to replace a suspected break in the carrier pipe serving the campground's sewer force main.

Elk Mountain Sewer Addendum Wind Cave National Park
National Park Service
PMIS 242482
February 2023
TABLE OF CONTENTS
1. Summary Project Description
This Addendum consists of furnishing and installing 2-inch carrier and 4-inch casing (HDPE DR11 200 psi) pressure pipe at WICA Elk Mountain campground. This sewer force main and casing pipe will replace and correct a suspected break in the carrier pipe. The carrier pipe and casing pipe will replace a section along the main campground road and on an existing service line pipe as shown on the attached drawing. Total length of pipe replacement is 438 lineal feet.
The carrier pipe leak is anticipated to be within the section of pipe on the plan drawing. However, it may be necessary to extend the length of replacement, if the broken carrier pipe is not found within this 438-foot section as shown on the plan set. The contractor may be asked and issued a modification extending the length of replacement.
Also, concrete patch is anticipated with a road crossing, a parking lot and a walking path as part of this project.
