Structural Civil Engineering Excellence

Robust Civil Construction Built on Engineering Rigor

Transforming architectural visions into permanent structural realities. Led by licensed Civil Engineer Varun Sangani, Rare Design Studio executes heavy RCC frames, commercial complexes, and bespoke residential builds across Ahmedabad with zero compromise on safety, IS codes, and timeline adherence.

Precision Engineering for Gujarat's Built Environment

Civil construction is the fundamental spine upon which every architectural beauty depends. A flaw in foundation compaction, an improper water-cement ratio in ready-mix concrete, or an uncalibrated rebar lap length can permanently compromise a building's longevity and invite incurable structural fissures.

At Rare Design Studio, our civil construction division is personally directed by founder Varun Sangani, a qualified Civil Engineer. We bridge the critical divide that so often plagues Indian construction: the gap between the architect’s creative drawing board and the harsh, high-stakes realities of the construction site.

Geotechnical Soil Mitigation & Foundation Engineering

The geography of Ahmedabad presents specific geotechnical challenges. From expansive black cotton clay in western developments (Shela, South Bopal, Sanand corridors) to variable sand strata along the Sabarmati riverbanks, a standardized foundation template is a recipe for differential settlement.

Before pouring a single batch of concrete, our engineering team conducts comprehensive geo-technical standard penetration tests (SPT). We calculate exact bearing capacities and design custom footing solutions—whether deep bored cast-in-situ RCC piles, monolithic raft foundations, or isolated stepped trapezoidal footings. Every foundation includes dual-barrier crystalline waterproofing and anti-termite soil barriers to prevent sub-soil chemical attacks.

Seismic Resilience Designed to IS 1893:2016

Ahmedabad lies in Seismic Zone 3. We calculate dynamic shear loads and integrate ductile detailing of reinforced concrete frames to ensure life-safety during seismic tremors.

Certified Tier-1 Raw Material Sourcing

We mandate primary steel billets (Tata Tiscon / Jindal Panther Fe550D) and 53-grade OPC/PPC cement from accredited plants, backed by manufacturer test certificates for every batch.

On-Site QA/QC Lab & Concrete Cube Testing

Slump cone tests are performed at point of pour. Test cubes are cured under controlled conditions and crushed on calibrated machines at 7-day and 28-day intervals to verify target compressive strengths.

AUDA, AMC & GDCR Regulatory Liaison

We navigate municipal set-back codes, Floor Space Index (FSI) allocations, fire safety clearances, and structural stability certificates required for municipal occupancy certificates (BU Permissions).

The Engineering Challenge

Excavating a 5.5-meter deep double basement directly adjacent to an operating commercial avenue along the SG Highway corridor. The challenge involved managing sandy silt strata with water table ingress during monsoon season without inducing soil slippage or structural settlement to adjacent commercial high-rises.

The Civil Engineering Solution

Engineered a continuous contiguous secant pile shoring wall along the plot boundary combined with multi-stage wellpoint dewatering. For the superstructure, we deployed M35 grade self-compacting ready-mix concrete with post-tensioned beam systems to achieve 11-meter column-free retail spans, paired with laser-levelled aluminum system formwork.

Zero structural settlement or lateral deflection recorded on adjacent commercial structures.
100% concrete compressive test cubes exceeded 28-day target strength by an average of 18%.
Handed over complete RCC shell and core 21 calendar days ahead of client deadline.

Civil Construction FAQs

What grade of concrete and steel do you use for RCC frames?

We use minimum M25 grade concrete for residential footings and columns, and M30 to M40 self-compacting concrete for heavy commercial frames. For reinforcement, we exclusively use Fe500D or Fe550D primary steel with high ductility for seismic safety.

Do you assist with AUDA and AMC municipal permissions?

Yes. Our civil engineering team coordinates all structural stability certifications, soil test documentation, and GDCR compliance requirements needed for municipal building approvals and final BU (Building Use) permissions.

What is the difference between item-rate and turnkey civil contracts?

In item-rate contracts, the client supplies steel and cement while we execute labor, shuttering, and machinery. In turnkey contracts, we handle end-to-end procurement and execution with transparent testing reports, eliminating client hassle.

How do you prevent basement and terrace leakage in Ahmedabad?

We deploy specialized integral crystalline waterproofing chemicals directly into the concrete mix, seal construction cold joints with swellable hydrophilic waterstop bars, and install multi-layer elastomeric polymer coatings with protective screeds.
