Parking Lot Concrete Pour SOW.docx

Parking Lot Concrete Pour for U.S. Coast Guard.

Project Location: U.S. Army Corp of Engineers Service Base USCG Schlimme Industrial Facility Dock 100 Arsenal Street Building 17 St. Louis, MO 63118

Project Manager: DCC Joseph T. Medfisch Office (571) 613-2251 Cell (724) 910-1596 E-mail: joseph.t.medfisch@uscg.mil

1. Project Overview This Scope of Work (SOW) outlines the requirements, specifications, and guidelines for the preparation and pouring of a concrete parking pad. The project aims to provide a durable, medium-duty parking surface capable of supporting standard commercial lot traffic.

2. Project Specifications

· Total Area: 2,900 square feet

· Slab Thickness: 6 inches (Classified as Medium Duty)

· Estimated Concrete Volume: 53.7 cubic yards

· Intended Use: Standard commercial parking, light-duty delivery trucks, and standard passenger vehicles.

3. Design & Structural Requirements

· Standard Compliance: All design and construction practices must comply with ACI 330 (Guide for the Design and Construction of Concrete Parking Lots).

· High-Stress Zones: Any specific areas designated for heavy loads (e.g., trash enclosure pads, loading zones, or dumpster routes) must be designed to a heavy-duty thickness of 6.5 to 8+ inches.

· Thickened Edges: The perimeter of the concrete slab must feature thickened edges (or integrated concrete curbs) to accommodate frequent wheel loads and prevent premature edge cracking.

4. Known Site Interferences & Obstruction Management To ensure safety and prevent property damage, the contractor must identify and coordinate work around the following known interferences on the site:

· Gas Meters: Maintain safe clearance distances in accordance with utility guidelines. Provide protective physical barriers (such as bollards) if the slab borders these utility points.

· Fencing: Protect existing property and boundary fencing during excavation and pouring. Any fencing removed temporarily for access must be restored to its original state.

· Ladder Ways / Safety Exits: Maintain clear, unobstructed access to all exterior ladder ways and emergency exits throughout both the construction phase and in the final slab layout.

· HVAC Units: Exercise extreme caution when operating machinery near ground-mounted HVAC systems. Ensure excavation, grading, and concrete placement do not disturb the units' foundations, electrical feeds, or refrigerant lines.

5. Construction Phases & Responsibilities Phase 1: Site Preparation & Subgrade

· Excavate the designated 2,900 sq ft area to the required depth, paying careful attention to the marked utilities and the known site interferences.

· Install and properly compact a gravel subbase to ensure uniform weight distribution and adequate subgrade support. Concrete strength is highly dependent on this underlying base.

Phase 2: Formwork & Reinforcement

· Erect formwork to accommodate the 6-inch slab thickness and perimeter edge specifications.

· Install necessary control joints to manage concrete shrinkage and reduce random cracking.

Phase 3: Pouring & Finishing

· Procure and pour approximately 53.7 cubic yards of concrete.

· Finish the concrete surface to provide adequate traction for vehicles and pedestrians (e.g., a standard broom finish).

· Ensure proper grading and sloping for water drainage to prevent pooling on the slab surface.

Phase 4: Curing & Cleanup

· Apply appropriate curing compounds or utilize wet curing methods as specified by the concrete supplier.

· Remove all formwork, clean the site of construction debris, and ensure the surrounding area is restored.

6. CONTRACTOR RESPONSIBILITIES

The contractor shall:

· Provide all labor, materials, tools, and equipment necessary to complete the repair.

· Ensure all personnel are properly trained and certified to perform the work.

· Comply with all applicable federal, state, and local regulations, including safety and environmental standards.

· Maintain a safe and secure work environment throughout the duration of the project.

· Coordinate with the Coast Guard representative to minimize disruptions to pier operations.

· Notify the Coast Guard representative immediately of any unforeseen issues or delays that may impact the project timeline.

SAFETY AND SECURITY.

U.S. Coast Guard IPD St. Louis is located at a secured facility on U.S. Army Corps of Engineers Service Base St. Louis, all persons require a valid State or Federal ID to obtain entry. The Contractor will provide the Project Manager a full list of the names of all personnel that will be working on-site.
