Harnessing Technical Expertise to Design Solutions

BIM Modeling & 3D Coordination Services (India)

Our BIM team delivers high-quality BIM modeling services (LOD 200–500) using Revit and Navisworks to produce coordinated 3D models that reduce on-site clashes and rework. We produce discipline-specific models (Architecture, MEP, Structural) and federated coordination models for execution-ready output.

By integrating clash detection, model-based quantity takeoffs and coordinated shop drawings, our BIM workflow shortens design cycles, improves procurement accuracy and lowers construction risk. We provide BIM execution plans, 3D coordination sessions and handover models for O&M.

• 3D BIM Modeling: LOD 200–500 coordination
• Clash Detection: Revit & Navisworks workflows
• Deliverables: Coordination models, shop drawings & COBie-ready output

MEP Design Engineering & Documentation

AD Contracts provides complete MEP design services across India — HVAC, plumbing, fire-fighting and electrical systems engineered for efficiency and compliance. Our MEP design packages include load calculations, duct routing, pump sizing, riser diagrams and single-line schematics tailored to project needs.

We combine MEP engineering with BIM coordination so services are clash-free and installation-ready. Our MEP documentation is prepared to meet NBC, IS codes and client-specific standards, easing approvals and reducing installation delays.

• HVAC, plumbing & fire-fighting system design
• Load & energy calculations, duct/pipe routing
• MEP coordination drawings & installation packages

CAD Drafting & 2D/3D Design Services Across India

Our CAD services deliver accurate 2D and 3D drafting — AutoCAD, MicroStation and fabrication-ready shop drawings. We convert concept designs into construction-ready documentation while maintaining strict QA/QC and version control to eliminate field discrepancies.

Whether you need as-built drawings, fabrication packages, or detailed installation drawings, our CAD team produces standards-compliant deliverables with fast turnaround and clear revision histories for smooth on-site assembly.

• AutoCAD drafting, technical detailing & as-built packages
• Fabrication/shop drawings and revision control
• Rapid CAD conversion & outsourcing-ready workflows

Mechanical Design Solutions (Pan-India)

Our mechanical engineering services include thermal and fluid system design, pump room layout, piping isometrics and performance simulation. We use engineering analysis to validate layouts and ensure long-term reliability.

For large industrial clients, we design modular systems for maintainability and energy efficiency; for buildings, we deliver compact mechanical cores that balance performance and lifecycle cost.

• Flow simulation and pump selection
• Energy-efficient layouts and MEP coordination
• Maintenance-friendly mechanical systems

Industrial Design Services for Manufacturing & Infrastructure

We provide turnkey industrial design solutions focused on productivity, safety and regulatory compliance. Our approach combines plant layout, material handling design and process integration to optimise workflow and reduce downtime.

From concept layout and equipment selection to piping and service routing, our designs are tailored for continuous-operation environments and include maintenance access, safety zones and ergonomic considerations.

• Plant layout & process integration
• Material handling & ergonomics
• Safety compliance & operational optimisation

Structural & Civil Design Engineering

Our structural engineering services deliver robust, code-compliant designs — from foundation systems to reinforced concrete detailing and steel structures. We ensure architectural and structural coordination to avoid rework during construction.

Using modern analysis tools, we optimise members for cost and constructability while providing full documentation for approvals and site execution.

• Structural analysis & reinforcement detailing
• Architectural coordination and shop drawings
• Seismic & serviceability checks per IS codes

Technical Design Services (Chandigarh Region)

For clients in the Chandigarh Tricity we provide localised technical design services with quick turnarounds, approvals support and on-site coordination. This localized capability complements our pan-India design offerings without diluting national relevance.

• Local code familiarity & approvals assistance
• Fast mobilization for nearby projects
• Integration with central project teams

Custom Engineering & MEP Design Packages

We create custom design packages for complex projects requiring multidisciplinary coordination. Our modular approach lets clients scale services from single-discipline packages to full EPC-aligned design delivery.

• Modular design bundles for phased projects
• Dedicated design leads & QA workflows
• Post-installation optimisation & O&M handover
