BEST Paradise CGHS is an occupied multi-storey society in Dwarka Sector 19, New Delhi. The society is evaluating a major structural repair, rehabilitation and retrofitting project — façade repairs, balcony strengthening, FRP wrapping, microconcrete, corrosion treatment, waterproofing and painting.
Estimated project value: ~₹11 crore. Structural audit and preliminary BOQ prepared by consultant. Technical Committee has raised governance and technical queries.
Core Principle: Repairs may genuinely be required. This framework ensures they are executed with full governance, transparency, quality control and financial accountability — protecting all 76 families.
Unlike new construction, retrofitting occupied buildings demands a higher standard of governance at every stage.
Deterioration behind plaster or inside columns is only visible after chipping. Actual damage extent is unknown until execution begins — making preliminary BOQs inherently approximate.
The primary financial risk is not rate escalation but quantity escalation. Without controls, billed quantities can far exceed estimates as hidden damage is uncovered zone by zone.
Residents live in the building throughout works. This demands block-wise sequencing, safety barriers, dust controls, noise protocols and advance communication at every stage.
Consultant, MC, Technical Committee, Contractor and 76 resident families must all be coordinated. Authority and accountability need to be defined clearly at each level.
Ten core guardrails that together create a professionally controlled execution model:
Consultant prepares precise zone-by-zone damage drawings before large-scale execution begins. Basis for all quantity control.
2–3 representative zones chipped and exposed before full execution. BOQ validated or adjusted jointly before commitment.
One block or section at a time — never the entire society simultaneously. Reduces disruption, enables zone-level QC.
Item rates, material brands and specifications locked before contractor appointment. No mid-project substitutions without approval.
Mandatory cube testing, FRP pull-out tests, material certificates, curing checks and inspection records with photo documentation.
All quantities measured jointly — Consultant + MC + Contractor — before certification. No unilateral billing permitted.
Payments released in stages tied to verified completion. 5% retention held until defect liability period ends.
Below 5%: Consultant. 5–15%: TC. 15–25%: General Body. Above 25%: fresh re-evaluation. No open-ended approvals.
Barricading plan, dust/noise protocols, parking allocation, child safety and emergency access defined before any work starts.
Regular updates for all residents. All MOMs, approvals and technical decisions archived digitally. No undocumented decisions.
