Turnkey PEB Building Delivery: Complete Guide to End-to-End Pre-Engineered Steel Structures
— By Maruti Hydraulics Limited
A comprehensive guide to turnkey PEB delivery — covering single-point accountability, end-to-end scope, delivery models, the full construction process, applications, and how to evaluate a pre-engineered building contractor in India.
Turnkey PEB delivery brings pre-engineered building design, fabrication, supply, erection, and handover under one accountable contract. For industrial project owners — whether setting up an AAC block plant, a food processing facility, a logistics warehouse, or a pharmaceutical factory — the turnkey model eliminates the coordination complexity and accountability gaps that plague multi-vendor industrial construction projects. A good turnkey PEB scope covers site assessment, structural engineering, primary and secondary steel members, roof and wall cladding, logistics, installation, inspections, and closeout documentation. Maruti Hydraulics delivers complete turnkey PEB structures across Maharashtra and India under IS 800:2007 and NBC compliance.
Why Turnkey PEB Matters: The Problem with Fragmented Contracts
The conventional approach to industrial building procurement in India involves three or four separate contracts: a structural design consultant, a steel fabricator, an erection contractor, and a cladding supplier. Each party has a different project manager, different documentation, and — crucially — different accountability boundaries. The most common and expensive problems in Indian industrial construction arise in the gaps between these parties:
- The structural designer produces anchor bolt drawings, but the civil contractor uses different dimensions — mismatch discovered during column setting, requiring core drilling and chemical anchors at ₹15–₹30 lakh cost
- The fabricator delivers columns and rafters on time, but the erection contractor's crane is busy on another site — 3–4 weeks of delay at ₹1–₹3 lakh per day in project financing cost
- The cladding supplier's purlin spacings do not match the cladding sheet module — requiring on-site modification of purlins, adding cost and programme risk
Turnkey PEB delivery puts all these interfaces under a single contract. One project manager coordinates design, fabrication, logistics, and erection. One contract defines the scope, timeline, and performance standards. One party is accountable for delivering a complete, functioning building on the agreed date.
India's PEB Market Context
India's PEB market crossed ₹17,000 crore in 2024 and is growing at 12.5% CAGR. The turnkey delivery segment represents approximately 60–65% of total PEB market value — reflecting the industry's shift from supply-only contracts (where the owner manages erection separately) to full turnkey delivery (where the PEB manufacturer also handles erection and cladding). The growth of the turnkey segment is driven by the increasing scale and complexity of industrial projects, where owners do not have the in-house capability to coordinate multiple steel construction contractors simultaneously.
Three PEB Delivery Models
PEB Supply Only: Design and fabrication only — the owner or a separate contractor handles erection, cladding, and civil works. Lowest contract value but requires significant owner-side project management capability. Suitable for experienced contractors who frequently build PEB structures and have established erection crews. Risk: interface disputes between the fabricator and the erection contractor over weld quality, dimensional accuracy, or missing components.
Supply and Erection: Steel building designed, supplied, and erected by one contractor — civil foundation works remain separate (typically handled by a local civil contractor). The most common model for MSME industrial projects in India. The PEB manufacturer takes responsibility for delivering a complete, plumb, and aligned steel structure ready for occupation. Civil works run in parallel under the owner's supervision or a separate civil contractor.
Full Turnkey Delivery: Design, fabrication, civil works, erection, MEP interfaces, closeout documentation, and after-support all under one contract. The owner has truly single-point accountability — one contract, one project manager, one performance guarantee covering the complete building from foundations to roof. This model is particularly valuable for first-time industrial investors who lack construction project management experience, and for projects where the building and manufacturing machinery are being procured from the same vendor (as in Maruti Hydraulics' combined PEB + AAC plant projects).
What a Complete PEB Contract Must Cover
When reviewing a turnkey PEB contract scope, verify that it explicitly includes:
- Design and engineering: General arrangement (GA) drawings, structural design calculations, anchor bolt plans, fabrication drawings, and all drawings required for statutory approvals. Design to IS 800:2007 and NBC 2016. Calculations stamped by a licensed structural engineer.
- Primary steel: All columns, rafters, knee braces, crane beams, and end frame members. Material specification (typically IS 2062 E250/E350 conforming steel), section dimensions, weld specifications, and coating system.
- Secondary steel: Purlins, girts, eave struts, ridge members, wall bracing, and all fasteners. Hot-dip galvanised or pre-galvanised specification for corrosive environments.
- Cladding and roofing: Roof sheets (Galvalume AZ150 or AZ200, pre-painted), wall cladding panels, ridge cappings, eave flashings, barge boards, gutters, and downpipes. Sheet profile, gauge (minimum 0.50 mm), and colour specification.
- Openings: Industrial rolling shutters, personnel doors, louvred ventilators, and roof access hatches. Sizes, operation type (manual/motorised), and structural frame specification.
- Civil works (for full turnkey): Column pedestals and foundation pads, floor slab (or reference to owner-furnished civil specification), drainage sleeves, and embedded items.
- MEP interfaces: Sleeves for electrical conduit penetrations through cladding, crane rail support brackets, and coordination with mechanical equipment foundations.
- Handover documentation: As-built drawings, structural design calculations, material test certificates, inspection records, erection methodology records, and manufacturer warranties.
The Six-Phase Turnkey PEB Process
Phase 1 — Consultation and Concept Design: Building brief review and site assessment. Preliminary layout (footprint, span, eaves height, crane tonnage, expansion direction). Structural system selection. Proposal with indicative cost and timeline. Duration: 1–2 weeks.
Phase 2 — Detailed Engineering: IS 800:2007-compliant structural calculations, general arrangement drawings, fabrication drawings, anchor bolt plans. Submission to statutory authority if required. Drawing approval cycle with client. Duration: 3–5 weeks from brief freeze.
Phase 3 — Fabrication: Primary frames (tapered I-section columns and rafters), secondary steel, crane beams, and cladding components manufactured in-house at Nashik. CNC plasma/laser cutting, automatic submerged-arc welding, shot-blasting, and painting. Every component pre-tagged with assembly sequence code. Duration: 8–12 weeks (concurrent with civil foundation construction on site).
Phase 4 — Logistics and Site Preparation: Sequenced delivery of pre-tagged components to site, aligned to the erection sequence drawing. Foundation and anchor bolt position verified against the GA drawing before column delivery. Erection equipment (mobile crane, man-lifts) mobilised. Duration: 1–2 weeks delivery, concurrent with foundation completion verification.
Phase 5 — Erection, Cladding, and Finishing: Column plumbing and base plate grouting. Rafter installation and bolted haunch connections torque-checked to IS 800 specification. Crane runway beam installation and alignment verified. Purlin and girt installation. Roof sheet and wall cladding installation. Ridge ventilators, skylights, gutters, downpipes, doors, and windows. Duration: 4–8 weeks depending on building size.
Phase 6 — Inspection, Documentation, and Handover: Structural erection inspection (column plumb, frame alignment, bolt torque). Cladding inspection (lap sealants, penetration flashings, gutter water-tightness). As-built drawings issued. Structural calculations and material test certificates compiled in project close-out dossier. Formal handover with punch list resolution. Duration: 1–2 weeks.
IS 800:2007 Compliance: What to Check
IS 800:2007 governs all structural steel design in India. For a turnkey PEB contract, buyers should verify compliance on these specific points:
- Section classification: All plate elements in columns and rafters checked for compactness to prevent local buckling under design loads
- Haunch connection design: Full-penetration welds at haunch connections, with weld size calculated for moment, shear, and axial force combinations under the governing load combination
- Column base plate design: Base plate thickness and anchor bolt number and size designed for combined axial, shear, and moment from wind and crane loads
- Deflection limits: Horizontal eave deflection limited to H/150 under wind (where H is column height) to protect cladding from damage; vertical rafter deflection limited to L/180 under gravity loads
- Stability bracing: Wall bracing bays and roof bracing bays designed for horizontal loads (wind, crane surge, seismic) with adequate stiffness to prevent sway instability
Clear Span Capabilities and Typical Industrial Applications
Clear span (column-free floor width) is the defining structural advantage of PEB over RCC. Typical clear span ranges for each application:
9–18 m: Small warehouses, vehicle service bays, pump houses, boiler houses
18–30 m: AAC block plants (300–600 CBM/day), food processing factories, pharmaceutical production sheds, small logistics facilities
30–50 m: Automotive assembly sheds, large warehouses, aircraft maintenance hangars for smaller aircraft
50–90 m: Large aircraft hangars, container freight stations, large span industrial buildings with heavy crane systems
For AAC block plant applications, 24–30 m clear span is the sweet spot — wide enough to accommodate a full autoclave row, EOT crane, and cutting line side by side without the production-flow interruption that interior columns create.
Erection Timelines by Building Size
Realistic erection timelines for turnkey PEB delivery in India:
Small factory/warehouse (up to 1,500 m²): 3–4 weeks erection, 1–2 weeks cladding = 4–6 weeks total on-site
Mid-size factory (1,500–5,000 m²): 5–7 weeks erection, 2–3 weeks cladding = 7–10 weeks total on-site
Large factory (5,000–15,000 m²): 8–12 weeks erection, 3–5 weeks cladding = 11–17 weeks total on-site
Mega shed (15,000+ m²): 14–20 weeks erection, 5–8 weeks cladding = 19–28 weeks total on-site
Foundation completion on site is the critical path predecessor. Erection cannot begin until anchor bolts are set and foundations have achieved adequate concrete strength (typically 7 days for pedestals, 14–21 days for raft foundations depending on mix design).
Applications by Sector
Industrial factories (crane integration, production layouts), warehouses and logistics hubs (wide spans, dock integration, racking-friendly column grids), AAC block and construction material plants (Maruti Hydraulics combines PEB shell and manufacturing machinery under one contract), cold storage (insulated PUF panel options, condensation management), commercial showrooms and auto dealerships, aviation hangars (spans to 90 m with specially designed knee-brace frames), institutional buildings (workshops, maintenance sheds, sports halls), and metro or railway maintenance sheds.

Frequently Asked Questions
What does turnkey PEB delivery mean?
Turnkey PEB delivery means one contractor manages the complete pre-engineered building project from design coordination to final handover — covering structural engineering, fabrication, logistics, erection, cladding, MEP interfaces, inspections, and closeout documentation. The owner has a single point of accountability instead of separately coordinating the structural designer, steel fabricator, erector, cladding team, and site vendors.
What is included in a full turnkey PEB contract?
A full turnkey PEB contract typically includes design and engineering (GA drawings, structural calculations, anchor bolt plans, fabrication drawings), primary steel (columns, rafters), secondary steel (purlins, girts, bracing, fasteners), roofing and wall cladding (sheets, panels, trims, gutters, downpipes), openings (shutters, doors, louvers), civil works (foundations, pedestals, floor slab), erection, MEP interface coordination, quality inspections, and full handover documentation with warranties.
How long does a turnkey PEB building erection take?
Erection timelines for a turnkey PEB building in India typically range from 45 to 90 days depending on building size, span, and complexity. A standard factory or warehouse of 2,000–5,000 sq m typically takes 45–60 days from steel delivery to cladding completion. Larger industrial buildings with crane systems, mezzanines, or complex MEP interfaces may require 75–90 days. Maruti Hydraulics provides project-specific erection schedules aligned with foundation readiness.
What standards apply to PEB construction in India?
Pre-engineered building structures in India are designed to IS 800 (General Construction in Steel — Code of Practice) for structural steel design, IS 875 for load combinations, and the National Building Code (NBC) 2016 for wind, seismic, and occupancy requirements. Cladding and roofing products are sourced to IS 14246 and relevant manufacturer standards. Maruti Hydraulics designs all PEB structures to these standards with structural calculations prepared by qualified engineers.
Can Maruti Hydraulics supply both the PEB building and the manufacturing equipment inside it?
Yes. Maruti Hydraulics has a unique combined offering for industrial projects — delivering both the pre-engineered building (PEB steel structure) and all manufacturing machinery installed inside it (AAC block plant, CLC block plant, dry mortar plant, brick machine, or other construction machinery) under a single project plan. This eliminates the interface disputes, coordination delays, and accountability gaps that arise when the building contractor and equipment supplier are separate vendors.
