1.0 Introduction

The Naval Surface Warfare Center, Corona Division, Surface Range Engineering Branch, RS12, requires a firm-fixed-price contract for the procurement of an observation tower at Marine Corps Base Quantico.

2.0 Background

The intent of the project is to construct observation towers at Range 7 and Range 9 located in Marine Corps Base

Quantico (MCBQ) to conduct range observation. The observation tower will be constructed using three (3) 40’ long, 8’ 6” high International Standards Organizations (ISO) shipping containers stacked three (3) containers high resulting in a three-level structure. The first floor level will be considered mixed-used space. The third floor level will serve as the observation floor and will include three (3) evenly spaced observation positions. Observation positions will be defined by window openings. The roof level will also be used as an observation level with a canopy covering 75% of the roof for protection from the elements. All floor levels and the roof will be accessible via an exterior stairwell. The structure will also include grounding and lighting protection.

3.0 Scope

The scope of work for this project includes all features of work as defined in the Issue for Construction (IFC) set of drawings for the Range 7 and Range 9 observation tower. The Contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, and supervision necessary to meet the requirements established in this Statement of Work (SOW) and the IFC drawings in provided in the solicitation. Section 6.4 (Exterior Enclosure) of this SOW identifies specific features of work included in the scope of the project.
