The building has not been occupied or maintained for several years. During this period, vandals entered and removed portions of electrical wire and other salvageable materials. The subject project includes an assessment of the existing condition and preparation of an estimate to restore the building to three basic service levels – as detailed below. 1. Secure the Building and Prevent Deterioration - Secure the building envelope from water damage and vandals – The minimal improvement scope includes securing all doors, windows, and other potential access ways. The roof should be repaired and made watertight. A security system should be installed and monitored to detect and vacate vandals should they return. 2. Restore all Systems – The assessment scope will include an inventory and cost estimate of required repairs to patch the floor, wall systems, power, lighting, painting, heating, doors, windows, ventilation, and other building basics. Restoration of all building systems would make the space suitable for a secure storage area for the treatment plant. 3. Remodeling – The assessment scope will include documentation of desired improvements to use the space as a maintenance shop. The improvements will likely include office space, shared computer space, and shop work areas. Deliverables Final Report – Prepare a final report including photographs and written assessment of existing building condition. Report to include description of required upgrades to meet each of the three service levels. DocuSign Envelope ID: BCE977A4-8529-4E0C-92F7-538E5C3605D3
