MEP (Mechanical, Electrical, Plumbing) Services by Sigma Solutions

Introduction

In a prestigious luxury mixed-use development project, the client aimed to integrate high-performance MEP systems to ensure comfort, safety, sustainability, and long-term efficiency. However, execution was hampered by clash detection issues, poor coordination, and regulatory hurdles. The developers turned to Sigma Solutions for end-to-end MEP consultancy and execution, known for their BIM-driven coordination, cost optimization, and technical excellence.

Challenges Faced

1. Design Conflicts Between MEP & Structural Elements

MEP layouts clashed with architectural and civil plans. Improper duct routes, electrical trunking overlaps, and water piping misalignments caused construction rework and design delays.

2. Energy Inefficiencies & High Utility Costs

The absence of an optimized HVAC strategy, inefficient lighting, and poor insulation led to rising energy costs and reduced environmental ratings.

3. Regulatory Compliance & Safety Risks

Fire safety norms, electrical load distribution, and water-saving standards were not being adequately addressed, risking legal non-compliance and safety hazards.

4. Plumbing & Drainage Optimization Issues

Unstructured plumbing networks and inconsistent drainage slopes threatened long-term water wastage and leak risks, especially in multi-floor areas.

5. Delayed Coordination with Civil & Interior Teams

Lack of synchronized scheduling between the MEP, civil, and fit-out contractors resulted in misaligned workflows and installation overlaps.

Solution Provided by Sigma Solutions

Sigma Solutions adopted a BIM-enabled MEP service delivery model with a focus on clash resolution, energy optimization, safety compliance, and execution efficiency.

Implementation Process

1. BIM-Enabled MEP Coordination & Clash Detection

Created a 3D BIM model integrating all MEP systems with architectural and structural layouts.
Used Navisworks for automated clash detection and resolution of HVAC ducts, piping, and electrical trays.
Enabled virtual walkthroughs for pre-execution coordination, saving time on site.

2. Energy-Efficient HVAC & Electrical Design

Installed smart HVAC systems with motion-based control and zoned air handling units (AHUs).
Designed and implemented LED-based lighting systems, along with daylight sensors and timers for energy efficiency.
Provided load analysis reports and implemented proper electrical panel distribution with surge protection.

3. Sustainable Plumbing & Drainage Network

Engineered a closed-loop water system with rainwater harvesting, dual plumbing, and greywater recycling.
Ensured proper slopes and pressure balancing in multi-storey drainage systems.
Used UPVC and HDPE piping systems to ensure longevity and leak resistance.

4. Fire Safety & Electrical Code Compliance

Installed advanced fire suppression systems, including sprinklers, fire extinguishers, and fire-rated cable trays.
Designed emergency power backup systems, including silent diesel generators and UPS panels.
Ensured full compliance with NBC, IS codes, and NFPA standards.

5. Contractor Coordination & Execution Monitoring

Conducted weekly progress reviews and on-site audits to ensure compliance with the MEP execution plan.
Coordinated seamlessly with civil and interior teams to sequence installations (e.g., concealed piping before flooring).
Delivered as-built MEP drawings for post-construction facility management.
