DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: This project involves work in two (2) residential housing buildings at the South Unit’s

Headquarters Area within THEODORE ROOSEVELT NATIONAL PARK, in MEDORA, NORTH

DAKOTA. Previous HVAC renovation engagements in 2022 revealed conditions of existing ductwork encased within the concrete floors of two employee dwellings that were significantly deteriorating. Planned installation of HVAC systems at that time was subsequently suspended and removed furnace(s) reinstalled to maintain operations until complete resolution of issues could be designed. This work will complete that effort. Two (2) HVAC systems (one in each dwelling) will be replaced entirely with new, existing systems will be removed, including to extent of abandonment of in floor plenums below existing furnaces, removal of existing chimney piping and patching roof penetrations for same. Installation of concrete pads for new equipment and installation of ductwork to furnish a vertical up-flow HVAC configuration with low wall return air grilles. Work within the buildings will involve a combination of contractor furnished labor, skills, materials and supplies in addition to the select government supplied mechanical equipment furnished under the previously cancelled contract. Equipment under this contract shall be configured to operate on Propane LP

Gas.
