2.0 Scope & Objectives

• This Method Statement details the complete procedure for Plain Cement Concrete (PCC) works[cite: 1].
• PCC with an aggregate size of 40 mm is utilized as a bed/levelling layer for foundations and flooring[cite: 1].
• PCC with an aggregate size of 20 mm is utilized for window sills, coping, and damp-proof courses (plinth concrete) incorporating waterproofing compounds[cite: 1].

• Verify that ongoing activities adhere to the planned construction program and that all required equipment is on site and in good operational condition[cite: 1].
• Coordinate with the Client/Consultant, Project Manager, Site Engineer, Safety Engineer, and Surveyor for safe, smooth execution[cite: 1].
• Enforce safety measures and quality control in conjunction with the Safety and QA/QC Engineers following the project HSE and Quality Plans[cite: 1].

6.2 Site Engineer

• Directly supervise PCC operations as per project specifications and construction drawings[cite: 1].
• Distribute daily site responsibilities and technical details to the construction execution team[cite: 1].
• Monitor daily work progress against the project schedule and report updates to the Project Engineer/Manager[cite: 1].
• Coordinate with Safety personnel to maintain safe working practices at all times[cite: 1].
• Coordinate with QA/QC engineers to initiate timely sampling, testing, and final inspections[cite: 1].
• Ensure maximum productivity from deployed labor and machinery, cross-checking outputs against daily foreman reports[cite: 1].
• Communicate updated drawing revisions to foremen promptly[cite: 1].
• Coordinate with the surveyor to verify lines, levels, and structural alignments[cite: 1].

6.3 QA Engineer

• Verify that all ongoing and completed PCC works comply with project specifications and quality procedures[cite: 1].
• Perform physical inspections of finished works prior to submitting requests for Client/Consultant approval[cite: 1].
• Maintain structured inspection and concrete test records for future reference[cite: 1].

6.4 Safety Engineer

• Enforce site implementation of all safety measures outlined in the HSE plan[cite: 1].
• Inspect active site areas to verify safety adequacy and conduct toolbox talks to prevent site incidents[cite: 1].
• Maintain clean and tidy work areas across all PCC activity zones[cite: 1].

6.5 Foreman

• Manage daily labor and equipment distribution in coordination with the Site Engineer[cite: 1].
• Submit daily output reports and assist in short-term work planning[cite: 1].
• Coordinate directly with surveyors for setting out and reference marking[cite: 1].
• Implement all safety and quality control requirements passed down by project engineers[cite: 1].
• Report any site delays or unforeseen site conditions to the Site Engineer immediately[cite: 1].

6.6 Surveyor

• Establish benchmarks from verified control points and provide all line, layout, and level markings[cite: 1].
• Maintain all survey data and perform periodic level checks on ongoing PCC pours[cite: 1].

7.0 Procedure / Method to be Employed

7.1 Site Preparation & Layout Check

• Verify layout, line, levels, and plan dimensions with the survey team prior to placing concrete[cite: 1].

7.2 Concrete Mix & Proportioning

• Nominal Mix: Use 1:2:4 (Cement : Sand : Coarse Aggregate) by volume when specified[cite: 1].
• Compressive Strength: Standard 1:2:4 nominal mix concrete must achieve a minimum 7-day compressive strength of 140 kg/cm²[cite: 1].

7.3 Concrete Mixing

• Hand Mixing: Permitted only on a watertight masonry platform or heavy-duty sheet iron tray[cite: 1].
• Machine / Batch Mixing: Load coarse aggregates, sand, and cement into the mixer drum in correct proportions to obtain a uniform distribution[cite: 1].

7.4 Slump Control

• Conduct standard slump tests regularly to control water additions and maintain concrete consistency[cite: 1].
• Maintain a slump range between 7.5 cm and 10 cm for general building works[cite: 1].

7.5 Formwork & Shuttering

• Provide sturdy shuttering and centering to support and confine concrete to design dimensions[cite: 1].
• Apply approved shuttering oil on inner faces to prevent concrete sticking upon stripping[cite: 1].

7.6 Concrete Placement & Compaction

• Deposit concrete gently into place (do not drop from height or throw) in uniform layers not exceeding 15 cm in depth[cite: 1].
• Compact thoroughly using steel rods, wooden tampers, or mechanical immersion/screed vibrators to eliminate voids and achieve maximum density[cite: 1].
• Ram and finish the top concrete surface smooth to correct design levels[cite: 1].

7.7 Curing

• Initial curing must begin within ~2 hours of placement as soon as the surface hardens[cite: 1].
• Keep surfaces continuously damp by covering with wet gunny bags or wet sand for at least 24 hours[cite: 1].

8.0 Material Requirements

Coarse Aggregates

• Must consist of inert, clean, dense, hard, durable, non-absorbent, broken stone (granite or equivalent)[cite: 1].
• Free from dirt, clay, organic matter, and dust[cite: 1].
• Graded 20 mm nominal size and below, completely retained on a 5 mm square mesh, with voids not exceeding 42%[cite: 1].

Fine Aggregates (Sand)

• Clean coarse sand with hard, sharp, angular grains passing through a 5 mm square mesh[cite: 1].
• Free from silt, clay, organic impurities, and salts. Sea sand is strictly prohibited.[cite: 1]

Cement

• Fresh Portland cement conforming to ISI standards with proper strength and fineness[cite: 1].
