MEP Budget for a 50,000 sq ft Factory: The Systems List and What Moves the Number

The MEP budget for a 50,000 sq ft factory (about 4,645 m²) is set by the process load list and the fire hazard class more than by the shed's area. List the systems, size each from the equipment schedule, and price each line on a common scope. No honest rate exists without your load list, so this guide gives the list, the inputs behind each line and the order to fix them.

What is on the systems list?

A factory MEP package has six core systems and one optional one. The table shows what each covers and what decides its size, so you can see which lines scale with area and which are lump sums.

If solar is in scope, price it as its own line. Our published band for commercial and industrial solar is ₹24,000 to ₹32,000 per kW excluding GST, on the solar EPC page; roof, structure and DISCOM terms move a plant within it.

What fixes the electrical line?

The load list, not the lighting. The equipment schedule gives connected load; a demand factor turns it into a demand; redundancy decides whether you need one transformer or two. For lighting, ECBC 2017 gives 12.0 W/m² for a manufacturing facility in its building-area table. On 4,645 m² that is an allowance of about 55.7 kW for lighting. ECBC formally applies to commercial buildings and excludes process loads, so use the figure as a design benchmark, not a rule, and compare it with the lux level the process needs.

Connected load also triggers statutory duties that cost time and money. Regulation 5(3) of the CEA safety regulations 2023 requires a factory with more than 250 kW connected load to designate an Electrical Safety Officer with an electrical degree and five years of experience, or a diploma and ten years. An HT connection brings the Electrical Inspector's approval before supply (Regulation 45) and substation rooms with their fire and oil provisions; our note on transformer undersizing covers what late growth costs.

What fixes the fire line?

The hazard class and the fire authority. NBC 2016 Part 4 divides industrial buildings into G-1 low, G-2 moderate and G-3 high hazard, and says the Authority determines the hazard from the fire loads of contents and the processes carried out. Table 7 of the same Part states its Group G requirements for small-scale industry units; for other industries they are worked out from the relevant Indian Standards with the local fire authority. A 50,000 sq ft shed storing plastics or packaging in racks sits in a different class from one doing light assembly, and the tank, pump set and sprinkler scope follow.

So ask the fire officer for the hazard class before you take a fire quote. The pump house, tank and yard ring are the lumps that do not shrink for a small shed. Our guide to NBC 2016 for factories and the fire NOC guide set out the sequence.

What fixes the HVAC, water and wastewater lines?

HVAC follows the heat load and the rooms that need controlled air. Most of a 50,000 sq ft shed is ventilated, not air-conditioned; the conditioned part is usually the office, the control room and any process area with a temperature or humidity limit. Each such room adds cooling capacity, ducting and electrical load, so list them one by one. Water and drainage follow headcount, process water use and site levels. The wastewater line follows the daily flow and the quality the pollution board's consent allows at discharge: a plant that discharges only domestic sewage needs an STP, while one whose process produces effluent needs an ETP as well, which is a different and larger scope. Confirm your category with the board, as set out in our pollution consent guide, before you carry a line for it.

What sits outside the MEP budget?

Most budget gaps are scope gaps. Check each of these is named as in or out.

• Statutory fees for fire, pollution consent, factory licence and DISCOM connection.
• Civil builder's work: plant rooms, cable trenches, tank excavation, equipment plinths and roof supports.
• Process utilities such as compressed air, process chilled water and vacuum, which many factory owners buy from the equipment supplier.
• The DISCOM's charges for the connection and any line or bay it builds.
• Owner-supplied equipment, and design fees where design is a separate appointment.

How do you build the budget step by step?

1. Freeze the equipment schedule with each machine's electrical load, cooling load, water use and heat output.
2. Get the hazard class and storage plan from the fire officer.
3. Estimate the electrical demand and decide the redundancy: single or double transformer, one DG or two.
4. Decide what is air-conditioned and what is only ventilated. Our note on shopfloor cooling versus comfort HVAC explains the call.
5. Ask for quotes by system on one written scope, and compare them line by line. See how to compare MEP quotations.
6. Enter low, base and high rates in the MEPF budget calculator, add fixed items, then put contingency on a stated pre-tax base and tax on its own line.

The calculator prices your own discipline rates, not a figure of ours, and it treats a per-square-foot rate as a placeholder for a provisional sum before design, never as an award price. The award figure comes from a BOQ measured off drawings.

How Secured Engineers helps

Secured Engineers designs electrical, fire, HVAC and plumbing systems in-house and can deliver the whole MEPF package, with solar, under one contract. Fire NOC, CEIG and DISCOM net-metering filings are handled in-house. We work from offices in Noida (Delhi NCR) and Ludhiana. The company has delivered 535+ projects across 18+ states, with 89.77% repeat clients.

If you have a layout, an equipment schedule or a draft BOQ, we can review the budget: what each system needs, which lines are missing from the quotes, and which numbers are still guesses.
