3. Civil Design Narrative The civil scope involves replacing the existing concrete pavement at the loading dock, sloping the new surface toward a trench drain to improve drainage, and installing protective bollards around the existing stitch gear to prevent equipment damage.

3.1 General Design Parameters and Assumptions

• The Contractor must locate all existing underground utilities before any excavation or demolition.

• Any dewatering needs to be pumped and hauled to the ITWP

• Any excavation needs to be stored in a lined container, tested, and disposed of in accordance with sampling results. (Ref. Tinker Hazardous Waste Management Plan)

• Remove all existing concrete pavement within the loading dock area.

• Install a new trench drain system and connect it to the existing stormwater line.

• Install protective steel guard rails around the existing switch gear to prevent impact damage.

3.2 Existing Conditions and Demolition

• The Contractor must locate all existing underground utilities before any excavation or demolition.
