BSEL Tech Park Premises Co-operative Society Ltd.

Location:
Sector 30, Vashi, Navi Mumbai

Project Type:
Repair & Rehabilitation Project – PMC (Project Management Consultancy)

Building Details
Structure: Commercial IT Tower
Configuration: 3 Basements + Ground + 14 Upper Floors

Built-up Area: Approx. 2,50,000 sq.ft.
Year of Construction: Circa 2005

Background & Objective
The management of BSEL Tech Park observed recurring leakage, corrosion, and plumbing failures within service ducts and terrace zones.
Frequent complaints of foul odor, water seepage, and damaged finishes were affecting tenants’ operations and maintenance costs.

To address these challenges in a structured and transparent manner, Valorem Engineering Pvt. Ltd. was appointed as the Project Management Consultant (PMC) to handle the entire repair process from assessment to execution monitoring.

The project required technical expertise, cross-coordination between multiple contractors, and strict quality control, given the operational nature of the building with ongoing office activities.

Scope of PMC Work
Preliminary Structural & Plumbing Audit
– Inspection of 14 service ducts (vertical risers)
– Assessment of RCC members, plumbing joints, and drainage systems
– Identification of unsafe, deteriorated, or corroded sections

Planning & Tendering
– Preparation of Repair Estimate, BOQ, and Tender Documents
– Technical vetting of contractors and comparative analysis
– Assistance in contractor selection through transparent process

Execution Supervision & Quality Control
– Daily on-site supervision and progress tracking
– Verification of quantities and workmanship standards
– Approval of material brands and mix designs (plumbing + civil repair)
– Testing and inspection through NDT and visual verification

Coordination & Documentation
– Periodic review meetings with Society Committee and Contractors
– Monthly progress reports and photo documentation
– Coordination between Structural, Plumbing, and Waterproofing teams

Safety & Compliance
– Ensured proper scaffolding, safety nets, and restricted working zones
– Compliance with NMMC and Fire Department norms for repair works

Challenges Faced
– Restricted access due to active corporate offices operating during daytime
– Complex vertical duct system with existing 4” soil, 3” waste, and 4” rainwater lines running continuously from terrace to basement
– Need for phased working and noise control to avoid operational disruption
– Coordination of multiple vendors under a single PMC umbrella

Valorem Engineering’s Approach
Valorem adopted a data-driven and methodical repair management strategy:

– Used drone-based façade survey for external condition mapping
– Carried out duct-by-duct documentation with measurement sheets and photographs
– Recommended selective replacement instead of full plumbing overhaul, resulting in significant cost optimization
– Introduced quality checkpoints and material inspection protocols for epoxy coating, clamps, and waterproofing

Results & Benefits
✅ Completed repair planning and execution monitoring for 14 vertical ducts
✅ Ensured seamless functioning of corporate offices during the work period
✅ Achieved cost savings of nearly 25% by optimizing replacement scope
✅ Enhanced plumbing performance, leakage control, and structural durability
✅ Provided end-to-end technical documentation and progress reports to the Society for future reference

Project Duration:
3 Months (Audit, Tendering, and Execution Monitoring)
