C. Site Preparation & Subgrade • Excavate to required depth (minimum 6–8 inches below finished grade or as needed for 4–5-inch concrete + base). • Remove all unsuitable material (soft, organic, or debris). • Compact existing subgrade to 95% of standard Proctor density. • Install 4-inch minimum compacted crushed aggregate base (Crushed Surfacing Top Course or approved equal) meeting local specifications. • Grade and compact base to provide proper drainage and ADA-compliant slopes. D. Concrete Placement & Finishing (ADA-Compliant) • All sidewalks and entry walkways shall be Portland Cement Concrete (PCC), minimum 4 inches thick (7 inches thick where crossed by driveways or heavy vehicle paths). • Concrete mix design: • Minimum 4,000 PSI compressive strength at 28 days. • 5–7% air entrainment. • Reinforcement: # 3 rebar 18" o.c.e.w .

No smooth trowel finish. • Joints: • Control joints: Saw-cut at maximum 8–10 ft spacing (or match existing pattern). • Expansion joints: Pre-molded joint filler at 50 ft maximum or where abutting fixed objects. • ADA Needs : • Minimum clear width: 36 inches (48 inches preferred where feasible). • Maximum running slope: 5% (1:20) unless ramp conditions apply. • Maximum cross slope: 2% (1:48). • No vertical changes > ¼ inch (bevel 1:2 for ¼–½ inch). • Stable, firm, slip-resistant surface. • Curb ramps (where required) at 1:12 maximum slope with proper landings. E. Curing, Protection & Restoration • Apply curing compound or wet cure for minimum 7 days. • Protect new concrete from traffic, weather, and damage for 7 days minimum (or until 3,000 PSI achieved). • Backfill and restore all disturbed areas (sod, seed, mulch, or landscaping) to match existing or better. • Clean and restore adjacent surfaces (buildings, curbs, asphalt, etc.). F. Cleanup & Demobilization • Remove all debris, equipment, and materials daily. • Sweep and wash down streets/sidewalks. • Final site cleanup and punch-list walk-through with MHA representative. 4.
