St. Clair.PHN.Cable install estimate. F1 re-locate.pdf

This document is a cable installation estimate and site map for the St. Clair County International Airport, prepared in support of an MDOT AWOS (Automated Weather Observation System) Concrete and Electrical Work project in Michigan. The file provides a detailed geographic representation of the airport facility, specifically identifying the approximate locations of underground cable infrastructure and installation points. The map uses color-coded markers to distinguish between existing AWOS underground cables (shown in white) and proposed cable installation or intercept points (shown in yellow). The document notes that the white box area may contain usable conduit running beneath the runway, which could be leveraged for the cable installation work. Geographic coordinates are provided (44.987267561, -085.200954861) with a scale measurement indicating 1,000 feet north, enabling precise identification of work areas and underground utility locations.

This estimate document serves as a planning tool for the electrical and cable installation components of the broader AWOS project. By identifying existing underground infrastructure and proposed installation points, the document facilitates accurate cost estimation and project scope definition for contractors bidding on or executing the concrete and electrical work required at the airport facility. The map's delineation of usable conduit represents a potential cost savings opportunity by utilizing existing infrastructure rather than requiring new conduit installation, which is relevant to both project budgeting and logistical planning.
