From a brief
to a building.
Walked, not handed off.

We are a turnkey engineering and construction studio in Chennai. Pre-engineered buildings, civil works, conventional steel and the MEP scope to commission them — designed, fabricated and erected by one accountable team. This page is a walk through how a project actually moves through us.

// Brief & site visit

We walk the site
before we draw a line.

Within 48 hours of your enquiry, a senior engineer is on your site. We measure access, soil conditions, neighbouring structures and operational constraints — then put the brief in writing so everyone agrees on what's being built before any drafting begins.

"Site visits are not a checkbox. They are where bad assumptions get killed early."

// Concept & massing

From scribbles
to a scheme.

// massing study · 02SCHEME 03 OF 04
// Drop concept sketch or SketchUp renderStage 02 · Studio

We translate the brief into structural massing — usually 3 to 4 schemes. Clear span versus column grid, eave height versus crane lift, single-bay versus multi-bay. We bring back drawings you can mark up with a pencil, not slide decks you have to politely sit through.

"Three schemes, not one. So you can choose, not just nod."

// 3D Renders & client sign-off

Once the scheme is frozen, we take you inside the building before any steel is rolled. Lumion and Twinmotion renders show envelope, structure, crane access and circulation. Walkthrough VR available on request for projects above 30,000 sq.ft.

// Detail engineering

Drawings that
can be built from.

STAAD analysis, Tekla detailing, connection design, embed schedules, BBS. Every drawing is reviewed by a senior engineer before release — no fresh-out-of-college BIM pushed to the fabricator on a Friday evening.

// Fabrication

Cut, welded,
painted, packed.

In-house fabrication across two bays — soon three. Calibrated welding, MPI on critical joints, batch traceability from coil to finished member. We don't sub primary structurals. The people fabricating your steel sit fifty metres from the people who designed it.

"350 tonnes a month — every weld traceable to the welder who ran it."

// Erection & MEP

The building
goes vertical.

Civil hand-off, anchor-bolt survey, primary erection, secondary structurals, sheeting, then MEP. A senior engineer is on site every day of erection. Weekly photo reports go to your inbox whether you ask for them or not.

"You shouldn't need to call your contractor to know what happened on Tuesday."

Have a brief, a site,
or a deadline that
won't wait?

We'd rather walk a site than read a slide deck. Send us what you've got — we'll come look, and you'll have an indicative number inside five working days.
