MEP Project Value Engineering for Indian Commercial — SAVE Intl + ASHRAE + RIBA 2020
A 40,000 sqm office MEP VE exercise — done at Stage 3 Detail Design — returned ₹3.8 Cr capex saving (-9 %) plus ₹162 lakh / 25-yr OPEX saving without removing function. SAVE International Value Methodology + ASHRAE Guideline 0 + RIBA 2020 frame this as a 6-phase function-analysis discipline, not cost-cutting. Three VE traps Indian projects keep falling into: descoping framed as VE, late-stage Stage 5 VE catching only 2-3 %, and single-stakeholder workshops missing FM operability tradeoffs.
What MEP value engineering actually means
Value engineering (VE) is NOT cost-cutting. SAVE International + ASHRAE define VE as a formal 6-phase function-analysis exercise that improves the ratio of function to lifecycle cost. For Indian MEP, the typical 6-12 % capex reduction unlocked by VE comes from substitution + redesign + spec tightening — never from removing function. This piece walks through a 40,000 sqm office VE exercise that returned ₹3.8 Cr capex savings (-9 % of MEP) without losing performance.

Three VE traps Indian projects fall into
- Cost-cutting framed as VE — removing redundancy, downgrading chiller IPLV from 0.50 to 0.62 kW/TR, or eliminating BMS analytics is not VE. It is descoping. True VE preserves function while lowering total cost of ownership.
- Late-stage VE — VE done in Stage 5 (Tender) or later catches 2-3 % savings only. The big returns (6-12 %) come from Stage 2-3 (Concept + Detail Design) when massing + envelope + load profile can still be retuned.
- Single-stakeholder VE — VE workshop without commissioning agent + FM + tenant rep produces false savings. FM team needs to sign off on long-term operability tradeoffs.
