: Senior Manager Tendering & Estimation (HVAC)

Designation: Senior Manager Tendering & Estimation (HVAC)

Location: Sewri, Mumbai

Experience: 10–15 Years

CTC Budget: 16–18 LPA

Working Days: 6 Days a Week

Qualification: B.E./B.Tech in Mechanical Engineering

Industry: Data Center EPC / HVAC / MEP

Mandatory Requirement: Prior experience in the data center industry.

1. Role Purpose

To lead end-to-end HVAC tendering and estimation for data center projects, with strong expertise in engineering calculations, equipment sizing, quantity take-offs, BOQ preparation, rate analysis and detailed cost estimation. The role requires a sound understanding of HVAC design engineering and critical cooling infrastructure to develop accurate, competitive and commercially viable bids aligned with project specifications and performance requirements.
1. Key Responsibilities

• Tendering & Bid Management: Manage the complete HVAC tendering process, including tender document review, scope assessment, technical clarifications, bid preparation and timely submission.
- HVAC Estimation & Costing: Prepare detailed cost estimates covering HVAC equipment, materials, piping, ducting, insulation, installation, manpower, subcontracting,

testing, commissioning, overheads and project margins.
- Quantity Take-Off & BOQ Preparation: Independently calculate quantities from HVAC drawings, layouts, schematics, equipment schedules and technical specifications;

prepare and validate detailed BOQs.
- HVAC Design & Engineering Calculations: Apply strong mechanical engineering fundamentals to validate cooling load calculations, equipment capacities, chilled water flow rates, pump sizing, piping dimensions, duct sizing and other relevant design parameters.
- Critical Cooling Systems: Estimate and evaluate chillers, CRAH/CRAC units, cooling towers, pumps, heat exchangers, chilled water piping, ducting, ventilation systems and associated HVAC controls.
- Drawing & Specification Review: Review HVAC layouts, schematics,



piping and ducting drawings, equipment schedules and tender specifications to identify scope gaps,

design discrepancies, quantity variations and technical risks.
- Rate Analysis & Cost Benchmarking: Prepare item-wise rate analysis, validate equipment and installation costs, benchmark market rates and identify cost-saving opportunities.
- Vendor & Subcontractor Evaluation: Obtain and evaluate quotations from OEMs,

vendors and subcontractors; prepare techno-commercial comparison statements and negotiate competitive rates.
- Technical & Commercial Bid Preparation: Develop BOQs, cost summaries, pricing schedules, technical submissions, commercial proposals, assumptions, exclusions and tender clarifications.
- Value Engineering & Risk Assessment: Identify cost optimization opportunities while maintaining cooling performance, energy efficiency, redundancy, reliability and compliance with project specifications.
- Cross-Functional Coordination: Coordinate with design, engineering, procurement,

projects and commercial teams to validate quantities, equipment selections, technical assumptions, installation methodology and project costs.
- Tender Handover: Prepare a comprehensive handover of finalized estimates, BOQs,

vendor quotations, scope assumptions and cost breakdowns to the project execution team after order finalization.
1. Candidate Profile

• B.E./B.Tech in Mechanical Engineering.
- 10–15 years of experience in HVAC tendering, estimation and cost engineering, with mandatory data center industry experience.
- Solid expertise in HVAC quantity take-offs, detailed estimation, BOQ preparation,



rate analysis and cost calculations.
- Sound understanding of HVAC design fundamentals, cooling load calculations,

equipment sizing, piping systems and technical specifications.
- Ability to independently interpret HVAC drawings and validate quantities and technical calculations rather than relying solely on vendor quotations.
- Experience estimating data center cooling infrastructure, including chillers, CRAH/CRAC units, chilled water systems and associated HVAC installations.
- Strong understanding of equipment costing, material costs, installation costs, labour productivity, subcontracting, overheads, contingencies and project margins.
- Proficiency in MS Excel; working knowledge of AutoCAD and HVAC design/drawing review tools is preferred.
- Experience in vendor negotiations, technical-commercial evaluations, cost benchmarking and value engineering.
- Strong analytical, numerical, commercial and coordination skills.

1. Preferred Technical Expertise

• Critical Cooling Systems: Chillers, CRAH/CRAC units, cooling towers, pumps, heat exchangers and chilled water systems.
- HVAC Engineering Calculations: Cooling load estimation, chilled water flow calculations, pump head and capacity, piping sizing, duct sizing and equipment capacity validation.
- HVAC Installation: Chilled water piping, ducting, insulation, ventilation, valves, supports and associated accessories.
- Controls & Integration: HVAC controls, BMS interfaces and coordination with electrical and other MEP systems.
- Tendering & Estimation: Quantity take-offs, BOQ preparation, detailed rate analysis,

vendor comparisons, cost benchmarking and bid pricing.
- Data Center Requirements: Critical cooling loads, redundancy configurations, system reliability, energy efficiency and commissioning requirements.

Compensation: 16–18 LPA, depending on experience and suitability.

Work Location: Sewri, Mumbai | 6 working days per week.
