Building Repair Services & PMC Solutions
At Nirman Projects Consultant, we deliver end-to-end Project Management Consultancy (PMC) services for building repair, structural rehabilitation, and waterproofing projects. Combining over 10+ years of registered structural engineering mastery with rigorous on-site quality control, our mission is to ensure durable, compliant, and cost-optimized building restoration for cooperative housing societies and commercial complexes.
We guide housing societies seamlessly through every project phase — from Structural Audit Review, Bill of Quantities (BOQ) preparation, and competitive tendering to daily site supervision, bill verification, financial closure, and final Structural Stability Certification across Mumbai, Navi Mumbai, Thane, Kalyan-Dombivli, and Mira-Bhayandar.

Methodology & Cost Estimation
Precise engineering specifications & budget planning:
- Preparation of suitable repair methodologies and technical specifications.
- Preparation of detailed, itemized project cost estimates (BOQ).
- Assistance with project planning, budgeting, and phase-wise scheduling.
Phase 2: Tendering & Contractor Selection
We assist the Society / Client with the transparent tendering and contractor selection process to secure the most qualified contractor at competitive market rates:
Tender Documents & Invitation
Comprehensive tender formulation:
- Preparation of comprehensive tender documents, specifications, scope of work, and terms & conditions.
- Inviting and managing tenders on behalf of the Society / Client.
Bid Evaluation & Site Visits
Unbiased comparison of contractor bids:
- Technical and commercial evaluation of contractor bids.
- Preparation of itemized comparative statements.
- Joint site visits with shortlisted contractors and Society representatives.
Contractor Capability Assessment
Rigorous multi-parameter background verification:
- Evaluation of contractors based on experience, technical capability, manpower, resources, financial capacity, and past performance.
- Formal recommendation of the most suitable contractor for SGM approval.
Contract Finalization & Agreement
Securing society interests with robust agreements:
- Preparation and finalization of legally binding contract documents.
- Inclusion of strict milestone schedules, defect liability terms, and payment clauses.
Phase 3: Project Execution & Quality Control
We provide professional project supervision and quality control throughout the execution stage to prevent shortcut workmanship, poor material mixing, and inflated contractor claims:
On-Site Engineering Supervision
Regular supervision by qualified Structural Engineers and Site Supervisors, with periodic inspections by Senior Structural Engineers.
Approved Technical Compliance
Ensuring execution strictly complies with approved structural drawings, repair methodologies, and material manufacturer specifications.
Material Inspection & Testing
Inspection and testing of construction, micro-concrete, polymer chemicals, and waterproofing materials, wherever required.
Measurement & RA Bill Certification
Physical verification and stage-by-stage certification of contractor running account (RA) bills against actual site measurements.
Phase 4: Post-Execution & Handover
Our services continue through the final stage of the building repair and waterproofing project to ensure full financial accountability and legal peace of mind:
Project Financial Closure
Complete documentation & accounts audit:
- Final measurement reconciliation and contractor final bill certification.
- Project financial closure documentation for society records.
Warranty & Handover
Formal guarantee & technical handover:
- Waterproofing warranty documentation handover from certified applicators.
- Complete structural documentation and project handover.
Structural Stability Certificate
Official municipal and statutory certification:
- Final inspection and certification upon satisfactory completion of the work.
- Issuance of Structural Stability Certificate, where applicable, upon satisfactory completion and compliance with the approved repair specifications.

Frequently Asked Questions on Building Repairs & PMC
Answers to key questions regarding building repair tenders, PMC supervision, society budgets, and warranty:
A Project Management Consultant (PMC) represents the Housing Society's best interest. Without a PMC, societies face arbitrary contractor estimates, substandard polymer mixing, unverified bill quantities, and lack of technical stability certification.
We prepare detailed itemized tender documents, manage the bidding process, conduct joint site visits, evaluate contractor capability and track records, prepare comparative rate analysis charts, and present recommendations in your Society SGM/AGM.
RCC Column Jacketing is a major structural strengthening technique using new reinforcement steel, shear connectors, and micro-concrete encasement to restore lost load-bearing capacity. Polymer Modified Mortar (PMM) repair is applied for superficial and moderate concrete spalling where existing rebar is cleaned, passivated with anti-corrosive primer, and sealed with high-strength polymer mortar.
Our qualified structural engineers supervise daily site execution, test micro-concrete cube strength and chemical mixing ratios, conduct mandatory 72-hour ponding water tests on terrace and toilet slabs, verify polymer bonding coats, and verify physical site measurements before certifying contractor RA bills.
We eliminate hidden costs by preparing an exhaustive, itemized Bill of Quantities (BOQ) with fixed unit rates and clear terms. No extra items or quantities are entertained without prior technical justification and written approval from our Structural PMC team.
The tendering and contractor selection stage typically takes 3 to 4 weeks. The on-site repair and waterproofing execution ranges from 4 to 8 months, depending on building height, total wings, monsoon windows, and the extent of structural distress. A detailed Gantt milestone chart is established before work commences.
Waterproofing treatments (terrace brickbat coba, PU elastomeric membranes, bathroom injections) come with official 5 to 10-year joint performance warranty certificates signed by the contractor and material manufacturers. All warranty documents are formally handed over to the Society managing committee.
Yes. Upon satisfactory completion of all approved repair scopes and engineering quality compliance, our Govt. Registered Structural Engineers conduct a comprehensive final inspection and issue the official Structural Stability Certificate compliant with municipal corporation norms (MCGM / TMC / NMMC).
