USCG Lorain – Flooring renewal

GENERAL REQUIREMENTS

PART 1 – GENERAL

1. SCOPE: The Contractor shall furnish all labor, materials, equipment, tools, transportation, and supervision required to perform complete structural rail demolition, slab trench infill, complete mechanical removal of existing floor paint, precision polymer re-grading to design drainage profiles, and installation of a multi-layer heavy-duty slip-resistant epoxy/urethane floor coating system within the existing boathouse facility. The contractor will provide a turn-key solution to deliver an even floor base with durable, slip-resistant, and high-performance floor system. The Contractor shall comply with all federal, state, and local regulations as well applicable Federal Acquisition Regulations (FAR), and consensus/technical standards (i.e.- OSHA, NFPA, ASTM, ANSI, etc.).

Contractors will coordinate on-site pre-bid visits with Contracting Officers Representative (COR) listed at end of this document M-F 0700-1430.

1.1. Service Conditions

The completed floor system must withstand harsh marine station operating conditions, including continuous exposure to fresh lake water, thermal variations, and concentrated mechanical wheel loads exerted by small forklifts and battery-powered electric pallet jacks. All transitions across the slab surface and through doorways must be monolithic, durable, and free of wheel-impact hazards.

2. EXISTING SITE CONDITIONS

2.1. Slab Dimensions: Exterior wall footprint approximately (effective slab area approximately 1,536 sq. ft.).

2.2. Embedded Tram Rails & Stop Blocks: Two (2) longitudinal steel tram rails (railroad profile) are embedded flush or semi-flush in the concrete slab, each measuring approximately 55 linear feet (110 total linear feet of rail). Structural steel/timber stop block assemblies are anchored near the rear interior wall.

2.3. Surface Coating: The existing slab has an existing layer of floor paint. 100% of this paint coating must be mechanically removed down to clean, unpainted aggregate concrete and all interferences removed.

2.4. Drainage Slopes & Contours:

2.4.1. Lengthwise Fall: The floor maintains a continuous longitudinal grade sloping downhill toward the main exterior door threshold at a pitch of ¼” per foot (approximately 12 inches total drop over the 48-foot distance).

2.4.2. Secondary Drainage Swales: Inward drainage valleys run longitudinally approximately 3 feet off the exterior sidewalls. All new mortar applications must preserve and follow these swale geometries so water discharges naturally out the doorway without ponding.

2.4.3. Clearance Constraints: Overhead roll-up doors, pedestrian man doors, and perimeter foundations cannot accept substantial elevation changes. The finished surface must feather to existing door threshold elevations.

3. TECHNICAL SPECIFICATIONS & EXECUTION

3.1 Protection of Coast Guard Assets

The Contractor shall protect all adjacent Coast Guard property, including masonry block walls, overhead roll-up doors, door track assemblies, and electrical equipment from concrete slurry, flying debris, and airborne dust.

All concrete sawing, grinding, shot blasting, and demolition tools must utilize integrated dust extraction shrouds connected to operational HEPA-filtered vacuum units in compliance with OSHA respirable crystalline silica standards.

3.2 Performance Objectives

3.2.1 Demolition, Extraction, and Slab Rehabilitation

Complete Removal: Extract and remove the two (2) 55-foot lengths of embedded steel tram rails and the rear-wall stop block assemblies. Demolish, unbolt, or torch-cut anchors flush with the underlying concrete.

Note: The tram rails do not need to be filled in their entire length to the exterior haul-out area; natural termination just outside of the boathouse threshold is sufficient.

Structural Trench Infill: Infill the resulting trenches and dished swales to establish a completely monolithic, structural concrete slab. The repaired sections must not settle, crack, or separate under concentrated forklift wheel loads.

Waste Management: Environmentally dispose of all demolished steel rails, stop blocks, concrete rubble, and debris off-site in accordance with local, state, and federal environmental regulations. Construction dumpsters must be covered.

3.2.2 Substrate Preparation and Coating Removal

100% Paint Removal: Mechanically remove all existing floor paint, sealers, oils, and contaminants from the 1,536 sq. ft. slab down to bare, porous, sound concrete aggregate.

Optimal Surface Profile: Establish a mechanical concrete surface profile (CSP) that ensures maximum chemical and mechanical adhesion of the proposed floor coating system.

Prohibited Methods: Caustic chemical strippers, solvents, and acid-etching solutions are strictly prohibited. Only mechanical methods (e.g., shot-blasting, diamond grinding) are allowed.

3.2.3 Slope Correction, Swale Preservation, and Threshold Integration

Preserve Natural Drainage: Ensure all grading modifications preserve the continuous ¼″ per foot lengthwise slope and the longitudinal cross-slopes. Water must drain naturally out of the boathouse door thresholds without ponding or pooling.

Low Spot Correction: Correct all low spots, surface depressions, and uneven joints.

Seamless Threshold Integration: Feather all transitions smoothly to the door thresholds and adjacent slab surfaces. No lips, steps, or level transitions greater than 1/16″ are permitted, ensuring smooth passage for forklifts and material handling equipment.

3.2.4 High-Performance, Heavy-Duty Floor Coating System

Waterfront Moisture Mitigation: Integrate a high-solids moisture vapor barrier/mitigation system that prevents osmotic blistering, peeling, or delamination.

Mechanical & Traffic Durability: Deliver an industrial-grade, multi-layer floor coating system designed to withstand heavy wheel traffic from material handling equipment without wearing through, chipping, or debonding.

Chemical & UV Resilience: Provide a finish coat that is highly stable against UV radiation from open bay doors and resistant to marine fuel, motor oil, hydraulic fluids, and the like.

Aggressive Slip Resistance: Establish a heavily textured, slip-resistant finish. Aggregate used must be angular (e.g., aluminum oxide) to resist pulverization; rounded quartz and silica sand are prohibited.

3.2.5 Operational Integration and Scheduling

Minimize Downtime: Develop and execute a schedule that minimizes operational disruptions.

Environmental & Cure Monitoring: Manage all temperature, dew point, and curing window conditions in accordance with chemical manufacturers’ guidelines to ensure a flawless chemical cure before turning the floor back over to Coast Guard material handling equipment.

4. QUALITY ASSURANCE & SUBMITTALS

4.1 Required Submittals

*Note- Tram rails do not need to be filled in the entire length to haul-out area. Natural termination just outside of the boathouse will suffice.
