Custom PEB Design

PEB engineering services that get the steel right the first time.

Our in-house structural team handles the full custom PEB design cycle — from feasibility studies and load calculations to detailed shop drawings and BIM coordination. We design to IS 800, AISC 360, and MBMA standards as part of our comprehensive PEB engineering services, using Tekla Structures and STAAD.Pro as our structural steel design platforms.

  • Structural load analysis (dead, live, wind, seismic)
  • 3D modeling in Tekla & STAAD.Pro
  • Foundation & anchor-bolt engineering
  • Thermal & insulation calculations
  • BIM coordination with MEP consultants
  • Wind-tunnel testing for high-span lightweight steel structures

How we work — PEB Project Management

A four-stage PEB construction process you can actually track.

Every turnkey PEB project moves through the same disciplined sequence — with weekly updates and a project manager assigned on day one.

01

Discovery

Site visit, load assessment, scope definition, and preliminary PEB cost estimation. Typically 5–10 business days.

02

Engineering

Detailed structural steel design, shop drawings, client sign-off. 2–4 weeks depending on complexity.

03

Production

Fabrication of pre fabricated steel buildings in our plants, with QC checkpoints at every weld. Shipped to site in phased deliveries.

04

Erection

On-site assembly by InfraNest PEB erection services crews, followed by snagging, handover, and warranty activation.
