Structural Work In Chennai
Structural Work
1. Introduction
This section outlines the scope, methodology, materials, and standards involved in the execution of structural work for the project. Structural work forms the backbone of the construction and must be carried out with strict adherence to design, safety, and quality standards.
2. Scope of Work
The structural works include, but are not limited to:
- Site preparation and layout
- Excavation and earthwork for foundations
- Construction of footings, foundations, plinth beams
- RCC columns, beams, slabs, and walls
- Staircases, chajjas, lintels, and other structural elements
- Water tanks, lift cores, retaining walls (if applicable)
- Backfilling and compaction around foundations
- All formwork, reinforcement, concreting, and curing works
3. Materials Used
All materials used in structural works shall be of approved make and quality, conforming to relevant codes and standards.
a) Concrete
- Grades: M20, M25, M30 (as per structural drawings)
- Ready Mix Concrete (RMC) or site-mixed, as per site conditions
b) Reinforcement Steel
- Type: TMT Bars (Fe500/Fe550)
- Complying with IS: 1786 or equivalent standards
c) Formwork/Shuttering
- High-quality plywood or steel shuttering
- Leak-proof and able to withstand concrete pressure
d) Admixtures
- Approved plasticizers, retarders, and waterproofing compounds (if specified)
4. Construction Methodology
a) Marking & Excavation
- Site to be cleared and layout marked as per structural plans.
- Excavation done as per depth and size specified, with proper shoring or dewatering as needed.
b) Formwork
- Accurate and aligned to drawing dimensions
- Cleaned and treated with shuttering oil before concrete pour
c) Reinforcement
- As per Bar Bending Schedule (BBS)
- Adequate cover blocks to be provided
- Checked and approved before pouring
d) Concreting
- Proper batching, mixing, placing, and vibrating
- Continuous pouring to avoid cold joints
- Temperature and slump checked before pouring
e) Curing
- Minimum of 7–14 days depending on mix and weather
- Wet curing or curing compounds as approved
5. Quality Assurance & Control
- Material testing (steel, cement, aggregates, water)
- Slump test, cube strength tests
- Pre- and post-concreting inspections
- Dimensional checks and tolerance verification
6. Health & Safety Measures
- Use of PPE: helmets, gloves, boots, harnesses
- Safe handling of steel and formwork
- Proper scaffolding and working platforms
- Emergency access and first aid availability
7. Applicable Codes and Standards
- IS 456: Code of Practice for Plain and Reinforced Concrete
- IS 1786: High Strength Deformed Steel Bars
- ACI, BS, ASTM codes (if international standards are required)
- Local Building Bye-laws and Regulations
8. Deliverables
- Completed structural frame as per drawings
- Test reports (cube test, steel test, etc.)
- As-built drawings
- Inspection and approval certificates
