MEP & Fire Fighting System Designer for Residential Building (India)

Project Overview: We are hiring an experienced MEP and Electrical System Designer with strong expertise in Indian residential building standards. The project requires a complete MEP + Fire Fighting + Electrical Distribution design package. The building uses individual split ACs (no centralized HVAC system). ⸻ Scope of Work 1. Mechanical (Ventilation & AC Coordination) • Ventilation design for staircases, lift lobby, basements/parking (if applicable). • Fresh air and exhaust design in compliance with NBC/local regulations. • Coordination for individual split AC units (indoor–outdoor routing, drain lines). • Outdoor AC unit placement plan and service clearances. ⸻ 2. Electrical System Design (Including Transformer & RMU) The designer shall deliver a complete electrical distribution system from HT to LT, including: 2.1 Load Estimation & Power Demand • Connected and demand load calculations for the entire building. • Diversity factor application for residential load as per Indian standards. • Determination of sanctioned load requirement for submission to DISCOM. 2.2 Transformer Sizing • Complete transformer sizing based on calculated demand load. • Selection of rating (e.g., 250 kVA / 315 kVA / 500 kVA etc.) as per site conditions. • Calculation summary including: • Load allocation • Transformer losses • Future expansion margin • HT/LT side protection • Transformer room layout and ventilation requirement. 2.3 RMU (Ring Main Unit) Design • RMU selection specifications (SF6/air-insulated). • HT cable routing and termination details. • RMU protection scheme and interlocking. • Layout drawings and single line schematic for HT distribution. • Compliance with DISCOM standards and fire-safety norms. 2.4 LT Panels & SLD • Main LT panel (MLTP) design including switchgear selection. • Sub-distribution boards for each floor and common areas. • Apartment distribution boards (DBs) with circuit zoning. • Protective devices: ACBs, MCCBs, MCBs, ELCBs/RCCBs. • Earthing/grounding layout and calculations. • Final Single Line Diagram (SLD) for the entire building. 2.5 LV Cable Routing and Trunking (Critical Requirement) • Detailed LV cable routing plan from: • Transformer to LT panel • LT panel to floor panels • Floor panels to apartment DBs • Cable tray/trunking design including: • Sizing of trays & cable containment • Horizontal and vertical routing • Shaft utilization and fire-stopping details • Segregation rules (power, lighting, data, fire alarm) • Cable sizing, voltage drop calculation & short-circuit analysis. • Earthing network design, lightning protection (if required). ⸻ 3. Plumbing & Drainage System • Water supply and distribution (UGT/OHT sizing, pump capacity, pipe sizing). • Internal plumbing for typical residential units. • External network, manhole layout & connection to municipal lines. • Rainwater drainage, harvesting provisions per local regulations. • Complete riser diagrams and hydraulic calculations. ⸻ 4. Fire Fighting System Design • Design of hydrant system, pump room sizing, sprinkler system (if applicable). • Fire extinguishers and hose reel layout. • Fire alarm system layout. • Emergency exit and signage. • All documents as per NBC 2016/2019 + Fire NOC norms. ⸻ Deliverables • Complete CAD drawings (MEP + Fire + Electrical HT–LT). • Transformer & RMU sizing report, HT/LT SLDs. • Cable routing layouts, tray/trunking details. • Equipment schedules and technical specifications. • Calculation sheets (load, transformer, pump, pipe sizing, voltage drop, etc.). • BOQ for all systems. • Final coordinated drawing set ready for contractor execution and authority approvals. ⸻ Candidate Requirements • Must have prior experience with residential MEP + HT/LT electrical design in India. • Strong knowledge of NBC, IS standards, CPHEEO, Fire NOC guidelines. • Ability to coordinate multi-system layouts and deliver accurate drawings. • Should be able to deliver calculations + drawings + BOQ professionally.
