# PEB Industrial Buildings & Warehouses

> A PEB industrial building or warehouse is a factory, logistics shed or storage building on a pre-engineered steel frame, chosen for large column-free spans and fast erection. Its programme depends on coordinating civil foundations, steel fabrication, cladding and services, since fabrication runs in parallel with foundation work on site.

## What we deliver

**Pre-engineered factories, warehouses, logistics sheds and industrial
buildings** — structure, cladding, civil foundations and flooring, and MEP
delivered together rather than split between a steel supplier and several site
contractors.

An industrial building is judged on a few things: clear span, clear height,
floor capacity, and how soon it can start operating. PEB is chosen because it
wins on all four — provided the foundations, the steel and the services are ready
for each other.

## Scope of works

| Stage | What we deliver |
| --- | --- |
| Design | Frame, bracing and secondary members to IS 800 and IS 875 |
| Civil | Foundations, plinth, anchor bolts, grade slab |
| Fabrication | Primary and secondary steel, shop-primed |
| Erection | Frames, bracing, purlins and girts |
| Envelope | Roof and wall sheeting, insulated panels where specified |
| Openings | Rolling shutters, dock doors, ventilators, skylights |
| Services | Electrical, lighting, firefighting and plumbing |
| Handover | Inspection, documentation |

## What drives the cost

Clear span and eave height · crane capacity · roof and wall cladding
specification · insulation · floor loading and slab thickness · number of dock
openings · fire protection required for the stored goods · site access for
steel delivery and cranes.

## Where projects go wrong

- **Steel arrives before foundations are ready.** Erection stalls and the steel
  sits in the open.
- **Grade slab designed without racking loads.** High-bay racking concentrates
  large point loads on the floor.
- **Fire requirements set after the design.** Sprinklers and hydrants change the
  roof height, water storage and pump room.
- **Ventilation and daylighting ignored.** Large sheds without them are hot and
  dark and need lighting all day.
- **Drainage undersized.** A large roof collects a great deal of water in a
  monsoon downpour.

## Why Hagerstone

**Single-partner execution** — PEB, civil, MEP and interiors under one integrated
team, so foundations, steel and services are sequenced by one programme.

**15 welders, 15 fitters, a 35-member firefighting team and a 53-member site
team in-house**, under ISO 9001 / 14001 / 45001 and 79+ quality checkpoints.

## Standards referenced

Steel design to **IS 800:2007**. Wind loading to **IS 875 (Part 3)**. Fire and
life safety for industrial and storage occupancy under **NBC 2016, Part 4**.

## Frequently asked questions

### Why is PEB the default for warehouses and factories?

Because it delivers large column-free spans quickly and economically. Tapered frames put steel only where the load needs it, fabrication happens in a controlled shop while the civil foundations are being built on site, and erection is fast once the anchor bolts are ready. For a shed that is mostly open floor with a roof over it, very few systems compete.

### How long does a PEB warehouse take?

Fabrication can run in parallel with foundation work, so the site programme is driven mainly by foundations, erection and cladding. The real variables are design freeze, steel procurement, and whether the civil works are ready when the steel arrives. A project where frame design and foundations are coordinated from the start moves far faster than one where they are handled by different parties.

### What about fire safety in a large shed?

Industrial and storage occupancies carry specific requirements under NBC 2016 Part 4 depending on what is stored and how — high-bay racking and combustible goods raise them considerably. Hydrant, sprinkler and detection requirements should be established before the building is designed, because they affect roof height, water storage and pump room space.
