2.1 GENERAL

2.1.1 Administrative Issues

2.1.1.1 Basic Design

Design drawings are provided as a method of communicating the basic design concept that the air station desires to execute. The intent of this project is to install a five coat epoxy flooring system with an integral vapor barrier in the hanger bay area in Hanger 1667. The existing concrete slab does not have a vapor barrier. The existing concrete floor will be prepared for the new coating system and the five coat system will be installed. The work will be installed in three phases and access and scheduling will be coordinated with the building occupant or organization. Each phase will be allocated no more than 30 days. Total construction time will be no more than 90 days. Phase 1 will be the North side, Phase 2 will be the Center, and Phase 3 will be the South side.

Each Phase will be BOD prior to the start of the next phase. A dust and debris barrier at least 6 feet high will be constructed between the sections where the work is in progress and the adjacent sections. The top coat/wear layer will be installed with a non-slip surface and painted walkway area as indicated. All non-permanent fixed equipment will be

The building tenants will be given one week to relocate their gear and aircraft between phases. The building tenants do not have any production schedules in place that will affect the Contract Completion Date. If during the construction phases, the weather temperature falls below 60 degrees, the contractor will be responsible for heating the floor and building area prior to placing the epoxy coats.

The work includes providing all labor, supervision, tools, equipment, materials, and transportation needed to test the existing slab for moisture penetration and install a five coat epoxy flooring system with a moisture barrier.

The units will coordinate with the Contractor to put in place a three phase work plan so the work can be accomplished in a timely manner and not adversely affect the Hanger operations. The Contractor will provide the manufacturer's standard warranty or better if requested.
