  • Starter (Kicker): A small height of concrete wall or column cast monolithically with the footing/slab to establish layout alignment for subsequent vertical lifts.
  • Shikanjas: Special clamping tools used to hold two opposite formwork panels or right-angle joints firmly during pouring.
  • Four-way Head: Structural support head mounted on props to hold I-section steel beams beneath slab or beam soffits.
  • Tripod: A three-legged support frame used to secure vertical props in an exact plumb and stable position.
Note: All site activities must align strictly with the approved Method Statement, Quality Control Plan (QCP), Inspection & Test Plan (ITP), and Project HSE Guidelines.

5. Health & Safety Hazards

Concreting operations involve heavy equipment movement, working at heights, handling hazardous chemical admixtures, and high-pressure concrete pumping. Specific safety precautions covered in the Project Safety Plan must be strictly enforced.

Potential Health & Safety Hazards
  • Contact with wet concrete causing chemical burns or skin irritation.
  • Failure or blowout of formwork and shoring systems under hydrostatic concrete pressure.
  • Structural collapse during concrete pouring due to improper prop placement.
  • Whip-hazard or blockage rupture of concrete pump pipes and hoses.
  • Working at heights during slab, column, or beam pours (fall hazards).
  • Noise and vibration hazards from concrete vibrator motors and transit mixers.
  • Trip hazards from exposed rebar, electrical cables, and formwork bracing.

7. Procedure / Method to be Employed

7.1 Pre-Concreting Activities

7.1.1 Document Verification & Mix Design Approval (For RMC / Site-Mixed)

  • The latest approved Mix Design report must be available on-site before starting any pour.
  • Mix trials shall conform to IS 456:2000 to verify workability, initial/final setting times, fresh density, compressive strength, and yield.
  • All concrete constituents (Cement, Mineral Admixtures like Fly Ash/GGBS, Silica Fume, Aggregates, Water, and Chemical Admixtures) must fulfill quality, durability, and structural requirements.
  • If Ready Mixed Concrete (RMC) is procured, the supplier must provide:
    • Manufacturer credentials & Batching Plant certification.
    • Proof of Conformance for all raw materials.
    • Plant calibration records and mix design compliance.

7.1.2 Surface Preparation & Formwork Setup

  • Subgrade, lean concrete, or existing slab surfaces must be thoroughly cleaned of debris, concrete waste, oil, and grease.
  • Wall/column layout lines are accurately marked on clean surfaces using markers or chalk lines.
  • Formwork panels are inspected for defects; deformed panels must be rejected.
  • Apply approved formwork releasing agent evenly. Releasing agent must not stain concrete or contaminate reinforcement steel.
  • Erect formwork sequentially following manufacturer drawings. Lock pins, wedges, and shikanjas securely.
  • Check soffit levels of beams and decks using auto-level. Verify wall verticality with plumb bob/tripod.
  • Check all block-outs, door/window openings, electrical conduits, and junction boxes against drawings.
  • Cover wall ties with plastic sleeves for easy removal. Ensure props and four-way heads are fully plumb and braced.
  • Gaps in formwork panels must be sealed using masking tape or 4–6 mm thick aluminum closure sheets (no loose plywood scraps / gabadi).

7.2 During-Concreting Activities

  • Continuous supervision must be maintained to ensure pins, wedges, and props do not loosen under vibration.
  • Pouring rate for vertical members (walls/columns) shall not exceed 2 meters per hour in height to avoid excessive lateral pressure.
  • High-frequency needle vibrators must be used systematically to ensure dense compaction without touching rebar directly or causing segregation.

7.2.1 Concrete Transportation & Delivery Ticket Inspection

Every transit mixer arriving at the site must carry a delivery ticket detailing:

Plant & Batching Information Site Delivery Entry Details
Depot Name / Number & Serial Ticket No. Exact arrival time on site
Date, Truck No., Purchaser & Site Location Time when discharge was completed
Concrete Grade & Target Workability (Slump) Water / Admixture added on site (if authorized)
Min. Cement Content, Cement Type & Grade Authorized signature for site water request
Max. Free Water-Cement Ratio & Max Aggregate Size Pouring location / element ID
Admixture type & dosage added at plant Signature of site representative accepting load

7.2.2 Field Quality Testing

  • On-Site Testing: Slump test, Slump Flow (for SCC), and Visual Stability Index.
  • Verification Reports: Temperature, Fresh Density (Unit Weight), Air Content, and Casting of Concrete Test Cubes for 7-day and 28-day strength.

7.2.3 Depositing Concrete into Forms

  • Verify formwork dimensions and cleanliness immediately prior to placing concrete.
  • Keep free fall of concrete to a minimum (maximum 1.5 meters) to prevent segregation.
  • For flat slabs, deposit concrete near its final location starting from corners/edges, working into previously placed wet concrete.
  • For vertical elements (walls/columns), place concrete in uniform horizontal layers (300–500 mm lift height).
  • When placing face mix and back-up mix in architectural concrete, ensure reinforcing is not contaminated with slurry that impairs bond.

7.2.4 Construction Joints

  • Locations of construction joints must be pre-approved by the Consultant/Engineers.
  • Joints shall be located where shear force is minimal, formed straight and perpendicular to the direction of main reinforcement.
  • Joint surfaces must be roughened, cleaned, and treated with cement slurry or bonding agent before fresh pour.

7.3 Post-Concreting Activities

7.3.1 Striking of Formwork

Formwork removal shall occur only after the specified minimum stripping period is met, in the following sequence:

  1. Wall and column vertical formwork.
  2. Deck props (leaving intermediate re-shores intact where specified).
  3. Deck panels.
  4. Beam soffit props.
  5. Beam soffits.
  6. Beam side panels.

Plastic tie sleeves and wall ties shall be pulled, and tie holes must be grouted with approved non-shrink repair mortar. Formwork faces must be cleaned immediately with scrapers and re-oiled.

7.3.2 Concrete Curing Procedures

  • Curing must begin immediately after initial set is established and concrete surface hardens.
  • Prevent rapid moisture loss / quick drying due to wind or high ambient temperature.
  • Accelerated curing (steam curing) shall not commence until initial set is complete.
  • Temperature gradients within structural members must not exceed 22°C (40°F).
  • Maintain moist curing (ponding, wet hessian cloth, or approved membrane curing compound) for a minimum of 7 to 10 days (14 days for concrete with mineral admixtures).
  • When steam curing, do not direct steam jets directly onto formwork; ensure uniform circulation.
