• Site Evaluation: Inspect soil type, drainage, slop and load requirements.
   
• Design & Engineering: Confirm slab thickness, reinforcement type (rebar or mesh) and concrete strength (PSI).
   
• Permits & Approvals: Obtain necessary Florida building permits and engineering approvals.
   
• Material Planning: Schedule delivery of concrete, form lumber, rebar, vapor barrier and tools.
   
• Safety Preparation: Review jobsite safety plan, PPE and OSHA compliance.

• Clearing: Remove vegetation, debris, old structures and organic material from slab area.
   
• Excavation: Excavate to required depth according to design and soil conditions.
   
• Compaction: Compact subgrade using plate compactor or roller to achieve uniform density.
   
• Moisture Check: Ensure no standing water; regrade and install drainage if necessary.
   
• Soil Proof-Rolling: Test compaction with proof-rolling for uniform firmness.

• Layout: Mark slab boundaries, corners and elevations using string lines and stakes.
   
• Form Setup: Install wooden or metal forms to correct dimensions and alignments.
   
• Form Bracing: Secure forms with stakes and braces to resist concrete pressure.
   
• Elevation Check: Use a laser level to confirm slab height and slopes for drainage.
   
• Apply Form Release Agent: Prevent concrete from sticking to forms for easy removal.

• Base Layer Placement: Spread crushed stone and gravel (typically 4–6 inches).
   
• Level & Compact: Compact base material to create a stable, even surface.
   
• Install Vapor Barrier (if required): Place polyethylene sheeting to prevent moisture migration.
   
• Tape Seams & Penetrations: Overlap and seal all joints and penetrations.

• Rebar or Mesh Placement: Position reinforcement per design (grid pattern or rebar layout).
   
• Chairs & Spacers: Support reinforcement to maintain proper height within slab thickness.
   
• Overlap & Tie Bars: Secure rebar overlaps with wire ties for structural integrity.
   
• Inspection: Conduct pre-pour inspection to verify placement, spacing and clearances.
   

• Concrete Delivery: Order proper mix (e.g., 3,000–4,000 PSI) and confirm slump consistency.
   
• Moistening Base: Lightly dampen base to prevent water absorption from concrete.
   
• Placement: Pour concrete continuously to avoid cold joints.
   
• Vibration & Consolidation: Use vibrators to remove air pockets and ensure full contact with reinforcement.
   
• Screeding: Level the surface with a straightedge to proper elevation.
   
• Bull Floating: Smooth the surface to embed aggregates just below the top layer.

  7. Finishing Operations 

• Initial Set Check: Wait until surface moisture sheen disappears (bleed water evaporates).
   
• Edging & Jointing: Round slab edges and cut control joints to prevent random cracking.
   
• Troweling: Finish surface to desired texture—steel trowel for smooth, broom finish for traction.
   
• Surface Protection: Cover slab if wind, heat, or rain conditions threaten curing process.
   

 8. Curing Process 

• Curing Method: Use curing compound, plastic sheeting, or wet burlap.
   
• Maintain Moisture: Keep slab surface damp for at least 7 days for strength development.
   
• Temperature Monitoring: Protect from rapid drying during curing.

 9. Form Removal & Final Work 

• Form Removal: Carefully strip forms after initial curing (usually 24–48 hours).
   
• Edge Repair: Patch any honeycombs or chipped edges.
   
• Expansion Joints: Install joint filler material between slab sections or adjacent structures.
   
• Site Cleanup: Remove debris, excess material and clean jobsite.

 10. Inspection & Quality Control 

• Surface Flatness: Check with straightedge or laser for tolerance compliance.
   
• Compressive Strength Testing: Use cylinder or core samples as required.
   
• Crack Inspection: Verify control joints and ensure no excessive cracking.
   
• Final Approval: Confirm alignment, finish quality and curing results before load application.
