What Should You Complete Before Construction Begins?
1. Verify land ownership documents: ensure you have the registered sale deed, mutation certificate, and encumbrance certificate. For DDA plots, confirm the lease deed and NOC for construction. Get a title search done by a property lawyer.
2. Get a soil test done: soil testing determines foundation type and depth. In Delhi, areas near the Yamuna or in Bawana/Narela may have weak or expansive soil requiring special foundations. Use a NABL-accredited lab and get a fixed quote against a written scope: the fee depends on the number of boreholes, their depth, and the laboratory tests. Bye-law 2.1.4 of the Delhi Unified Building Bye-Laws 2016 makes a geotechnical soil testing report mandatory for high-risk buildings (for residential use, 15 m and above or group housing).
3. Hire a licensed architect: the architect creates building plans compliant with Delhi building bylaws (ground coverage, FAR, setbacks, height restrictions). Agree the fee and the deliverables (drawings, approval file, site visits) in writing before work starts.
4. Obtain building plan approval from DDA or MCD: submit architectural drawings to the relevant authority (DDA for DDA areas, MCD/NDMC for their jurisdictions). Under bye-law 2.3.1 of the Delhi Unified Building Bye-Laws 2016, the authority must decide within 30 days or the shorter Chapter 3 limit for the building's risk category, and plots up to 105 sqm follow the simpler SARAL procedure in Chapter 4. Fees depend on plot size and category, and MCD/DDA publish current schedules. When you build with Nirman Ved, we prepare the approval file to the current bylaws.
5. Get a structural design from a licensed structural engineer: the structural engineer designs the RCC frame (columns, beams, slabs, foundation) based on soil test results and seismic zone IV requirements. The building plan application must include a Structural Safety Certificate (bye-law 2.1.3 of the Delhi Unified Building Bye-Laws 2016).
6. Finalise your construction company or contractor: obtain 3-4 detailed quotations, verify references, visit completed projects, and sign a formal agreement with scope, timeline, materials (with brand specifications), and payment milestones.
7. Arrange construction finance: if taking a home construction loan, note that banks disburse in stages linked to construction progress. Keep enough of your own funds ready to carry the first stages, because the bank releases money only as construction progresses.
8. Apply for temporary water and electricity connections: construction requires temporary utility connections from Delhi Jal Board and BSES/Tata Power. Apply well before the start date; the DISCOM and Delhi Jal Board set the charges, so check their current schedules.
9. Inform neighbours and RWA: for plots in cooperative societies, obtain RWA permission for construction. Some societies restrict construction hours and require deposits for common area damage protection.
10. Set up site security and storage: arrange for secure storage of materials (especially cement, steel, and fittings) and basic site security to prevent theft. Material theft is a real risk on open sites.
What Should You Check During Construction?
1. Foundation inspection: verify excavation depth matches structural drawings. Check PCC (plain cement concrete) thickness and curing. Inspect reinforcement bar diameter, spacing, and lap length before concrete pour. Ensure foundation waterproofing membrane is applied. This is a critical checkpoint: foundation errors are very hard to put right later.
2. Plumbing rough-in: verify pipe routing, diameter, and gradient before walls are plastered. Check that hot and cold water lines are correctly positioned, drainage slopes match the gradients on the plumbing drawings, and vent pipes are included. Pressure-test all water supply lines, at the test pressure and duration specified by the plumbing engineer, before the walls are closed.
3. Electrical conduit and wiring: inspect conduit routing before plastering. Verify wire sizes against the electrical drawings (AC and geyser circuits need heavier cable than lighting circuits), MCB ratings, earthing system, and switch board positions. Ensure conduits have pull wires for future maintenance.
4. Column and beam reinforcement: before every concrete pour, verify rebar diameter, stirrup spacing, cover blocks, and lap lengths against structural drawings. This is non-negotiable for seismic zone IV compliance in Delhi.
5. Slab reinforcement and shuttering: check slab thickness, steel placement (top and bottom), shuttering level accuracy, and ensure adequate props and supports. Take concrete cube samples during every pour, at no less than the minimum frequency in IS 456:2000 (clause 15.2.2: at least one sample from each shift; clause 15.3: three cubes per sample). The 28-day result decides acceptance, and 7-day cubes are an optional early check (clause 15.1.1).
6. Brickwork and wall alignment: verify plumb (vertical alignment), course height consistency, and mortar joint quality. If using AAC blocks, check adhesive application and block alignment. Lintels above every opening must match structural specifications.
7. Waterproofing application: inspect waterproofing at every wet area (bathrooms, kitchen, balcony) and at roof level. Verify membrane type, overlap joints, and conduct a water ponding test, for the duration in the waterproofing specification, before tiling. This guards against leakage, a common post-construction complaint in Delhi.
8. Plastering and pre-finishing checks: verify plaster thickness against the specification, surface flatness, and corner angles before painting. Check window and door frame alignment, level, and plumb before proceeding with finishing.
What Should You Verify After Construction?
1. Final walkthrough and snagging: conduct a room-by-room inspection noting defects: cracks, uneven surfaces, non-functional switches, leaking taps, misaligned tiles, and paint imperfections. Prepare a snagging list with photographs and set a deadline for rectification.
2. Systems testing: test all electrical circuits, verify MCB tripping, test all plumbing fixtures for flow and drainage, check geyser and water pump operation, and verify that the measured earthing resistance is within the value the electrical engineer specifies. Run the complete system under normal load before handover.
3. Warranty documentation: collect the structural warranty certificate, material warranty cards (tiles, fittings, paint), and equipment warranties (water pump, geyser, MCBs). Ensure the main construction warranty specifies duration, coverage, and claim process.
4. Obtain occupancy certificate: apply to DDA/MCD for the Occupancy-cum-Completion Certificate (OCC). This certifies the building was constructed as per approved plans. Bye-law 2.7.2 of the Delhi Unified Building Bye-Laws 2016 bars anyone from occupying a building until the OCC is granted, and a fresh Delhi Jal Board connection is applied for through the OCC request form.
5. Apply for permanent utility connections: with the occupancy certificate in hand, apply for permanent electricity meter, water connection, gas connection, and sewage connection. Departmental charges apply for each; check the current DISCOM, DJB, and IGL schedules.
6. Property mutation and tax registration: register the construction completion with the revenue department, update property mutation records, and start paying house tax. Also update your property insurance to cover the constructed structure.
What Are the Delhi-Specific Requirements You Must Know?
The Master Plan for Delhi 2047 (Tables 7.2 and 7.3 for plotted housing) and the Delhi Unified Building Bye-Laws 2016 govern ground coverage, FAR (floor area ratio), mandatory setbacks (front, rear, side), and maximum building height, with limits that vary by plot size. Work from the current bylaws rather than a neighbour's old sanction; violations invite demolition notices and significant penalties. Nirman Ved prepares the approval file to the current bylaws for every project.
Delhi falls in seismic zone IV (high damage risk zone). Clause 9.1 of the Delhi Unified Building Bye-Laws 2016 requires structural design to the National Building Code and the listed Indian Standards, including IS 1893 (earthquake-resistant design) and IS 13920 (ductile detailing), which govern how columns, beams, stirrups, and beam-column joints are sized and detailed. The building plan application must carry a Structural Safety Certificate (bye-law 2.1.3).
Under rule 27 of the Delhi Fire Service Rules 2010 (reproduced in Annexure V of the Delhi Unified Building Bye-Laws 2016), residential buildings need Delhi Fire Service clearance when they are more than 15 m high or have ground plus four upper storeys including a mezzanine; educational, institutional, and mercantile buildings cross the threshold at more than 9 m or ground plus two upper storeys. Rule 33 standards cover access to the building, exits, compartmentation, fire extinguishers, hose reels, and detection and alarm systems.
MCD/NDMC sanction is required before construction. The application goes online with the site, building, and service plans, ownership documents, and a Structural Safety Certificate, plus a geotechnical soil testing report for high-risk buildings (bye-laws 2.1.1 to 2.1.4). The authority must decide within 30 days or the shorter Chapter 3 limit for the risk category, or the plan is deemed sanctioned (bye-laws 2.3.1 and 2.3.4); for low-risk residential plots (vacant plots above 105 sqm up to 500 sqm, below 15 m), a qualified architect or engineer can issue the permit, or the authority grants it within 10 days (bye-law 3.1.1.2).
Large projects face environmental conditions tied to their total built-up area (clause 3.2 of the bye-laws), and the Delhi Pollution Control Committee is among the external agencies whose NOC the sanctioning authority obtains where it applies (bye-law 2.3.3). Construction and demolition waste management rules require proper disposal through authorised agencies; dumping construction debris is illegal and attracts significant penalties, and MCD publishes the current schedules.
