PEB Construction Timeline: What to Expect Month by Month
Quick Answer
A typical mid-size PEB project runs roughly: month 1 for design and engineering, months 1-3 for parallel fabrication and foundation work, months 3-4 for erection, and months 4-5 for finishing (flooring, MEP, doors) — totaling roughly 4-6 months for a mid-size industrial shed, though this varies with project scale and complexity.
Month 1: Design and Engineering
Requirements are finalized, structural design and load calculations are completed, and detailed fabrication drawings are produced. This stage's speed depends heavily on how quickly the client finalizes requirements — indecision here is one of the most common causes of overall timeline slippage.
Months 1-3: Fabrication and Foundation (Parallel)
Once design is locked, fabrication begins at the factory while foundation work proceeds independently at the site. This parallel-track approach is what compresses PEB's overall timeline compared to sequential RCC construction.
Months 3-4: Erection
Fabricated members are transported and erected once foundations have cured — primary frames first, followed by secondary members, bracing, and roof/wall sheeting.
Months 4-5: Finishing
Flooring, MEP work, doors and any interior finishing are completed, often overlapping with the tail end of erection to compress the overall schedule further.
