Professional Project Plan for Sidewalk Slab Pour

Project Overview

Project: Pouring a Concrete Sidewalk
Date: 9/17/24
Location: 27313 264th SE Ave, XXXXXX
Dimensions: 50 ft long, 5 ft wide, winding path
Thickness: 4 inches
Total Area: ~250 sq ft
Total Volume of Concrete: ~3.1 cubic yards (with 10% excess)

Materials and Quantity Estimates

Concrete

  • Ready-Mix Concrete: 3.5 cubic yards (with 10% excess)

  • Strength: 3,000 psi

  • Slump: 4 inches

  • Air Entrainment: 5-7%

Sub-Base Material

  • Crushed Gravel/Stone: ~5 tons (4 inches compacted)

  • Recommended Types:

    • Crushed Stone Aggregate (ASTM No. 57): Good drainage, excellent compaction.

    • Dense Grade Aggregate (DGA): Strong base, fills voids well.

    • Gravel (ASTM No. 67): Clean, washed stone; good for drainage.

Reinforcement (Optional)

  • Fiber Mesh: Integrated into concrete mix

  • Wire Mesh: 6x6 W1.4/W1.4 welded wire mesh

Formwork Materials

  • Form Boards: 2" x 4" lumber (16-ft lengths) for straight sections; flexible hardboard for curves

  • Stakes: ~50 wooden stakes (1" x 2" x 24") and 18-inch metal form pins

  • Form Ties & Braces as needed

Hardware & Expansion Materials

  • Duplex Nails (16d) and deck screws

  • Expansion Joint Strips: Asphalt-impregnated fiberboard (1/2" x 5")

  • Sealant: Flexible polyurethane caulk

Tools & Equipment List

  • Preparation: Tape measures, marking paint, shovels, wheelbarrows, plate compactor

  • Formwork: Hammers, clamps, drills, pry bars

  • Concrete Placement: Rakes, vibrators (optional), screeds, bull floats

  • Finishing: Edgers, groovers, brooms, steel trowels

  • Safety: PPE, first aid kit, warning signage

  • Miscellaneous: Water source, cleaning tools, lighting (if needed)

Step-by-Step Execution Plan

Day Before Pour

  1. Site Preparation (6-8 hours)

    • Mark path, excavate to 8" depth, remove debris.

    • Install & compact 4" sub-base layer.

  2. Formwork Installation (4-6 hours)

    • Set forms, ensure level and proper slope (1/4" per foot).

  3. Reinforcement & Expansion Joints (1-2 hours)

    • Install wire mesh and expansion joints at intersections and every 20 feet.

  4. Final Checks: Verify measurements, forms, and safety setup.

Day of Pour

  1. Pre-Pour (1 hour)

    • Team briefing, safety check, moisten sub-base.

  2. Concrete Placement (2-3 hours)

    • Pour continuously, screed, and bull float surface.

  3. Finishing (3 hours)

    • Edge sides, install control joints every 5 ft, apply broom finish.

  4. Curing: Apply curing compound, set barriers.

Post-Pour (Day 3)

  1. Remove forms (1-2 hours), clean joints, and apply sealant (1 hour).

  2. Site cleanup and tool maintenance (1-2 hours).

  3. Final inspection for compliance and quality (0.5 hour).

Timeline Overview

  • Total Duration: 2-3 days (21-30 hours)

  • Day 1: Site prep, formwork, reinforcement

  • Day 2: Pour, finish, and cure

  • Day 3: Cleanup, sealing, and final inspection

Safety & Compliance

  • PPE: Safety glasses, gloves, vests, hard hats, boots, and hearing protection.

  • Weather: Schedule during dry, moderate weather.

  • Permits: Ensure all local permits and zoning laws are met.

  • Emergency Plan: Accessible first aid and clear communication channels.

Recommendations for Smooth Execution

  • Confirm material deliveries 24 hours in advance.

  • Use checklists for tools and crew assignments.

  • Allow flexibility for unexpected delays.

  • Maintain clear team communication and regular progress checks.

Estimated Completion: 2 to 3 days with a focused and prepared crew.
