From Height Constraint to Functional Space: A Banquet Kitchen MEP Coordination Case Study

Executive Summary

This case study outlines the refurbishment of the Banquet Kitchen at a five-star hotel in Bengaluru, where restricted ceiling height and unavailable as-built drawings created significant MEP coordination challenges. Through detailed site verification, cross-disciplinary coordination, service rerouting, and careful sequencing around hotel operations, ANP PMC enabled the installation to proceed while maintaining performance, compliance, and operational continuity.

Introduction

The project involved refurbishment works in the Basement Banquet Kitchen of a five-star hotel located in Bengaluru's central business district. Set within a fully operational hospitality property serving both business and leisure travellers, the kitchen supports the hotel's banquet and event operations. As part of this brownfield project, the refurbishment had to be delivered while the surrounding facilities remained in active use.

The Challenge

The Banquet Kitchen is located on the basement banquet floor, where MEP installation was constrained by the limited ceiling height. The available service zone between the structural slab and finished ceiling was restricted to 2,500 mm and had to accommodate HVAC supply and exhaust ducts, fire protection pipework, drainage lines, electrical containment systems, and structural obstructions. Since original as-built drawings were unavailable, multiple service clashes had to be identified physically on site during execution. The proposed duct routing conflicted with existing fire protection and wastewater piping systems, preventing installation in accordance with the issued Good for Construction drawings.

Our Approach

After reviewing the Good for Construction drawings against actual site conditions, ANP PMC adopted a structured investigation, coordination, optimization, and execution approach in collaboration with the client and MEP consultants:

Investigation

  • Conducted site verification and service mapping because the original as-built drawings were unavailable.
  • Measured actual clearances against design assumptions and identified clashes between HVAC ducts, fire protection piping, and drainage lines.

Coordination

  • Held regular joint coordination workshops with the HVAC, plumbing, fire-fighting, and electrical consultants before execution to ensure alignment across disciplines.
  • Prepared revised, coordinated service layouts and presented recommendations to the client and MEP consultants.

Optimization

  • Revised the HVAC duct dimensions to resolve the clash while preserving the specified airflow performance.
  • Rerouted the existing drainage and fire protection service lines to eliminate the conflict with the ductwork.
  • Modified the duct routing hierarchy to avoid clashes with other service lines and achieve the required false ceiling height of 1950 mm from finished floor level.

Execution

  • Coordinated with hotel management to schedule disruptive works on non-event days, allowing execution to proceed with minimal impact on hotel operations.
  • Carried out planned shutdowns to connect refurbished services, including exhaust and drainage lines, to the main service network, enabling controlled execution despite the restricted working height.

The Outcome

  • Achieved functional MEP installation within the severe 2,500 mm height constraint.
  • Avoided costly demolition and rework during execution.
  • Preserved specified HVAC airflow performance despite space limitations.
  • Maintained compliance with fire protection and plumbing design requirements.
  • Achieved the required false ceiling height of 1950 mm and enabled hotel operations to continue with minimal disruption.
  • Demonstrated effective brownfield renovation management through proactive, cross-disciplinary coordination.

Conclusion

The Banquet Kitchen refurbishment reflects ANP PMC's ability to resolve complex brownfield service coordination challenges through sound technical assessment, collaborative planning, and controlled execution within an operating hospitality environment.

Lessons Learned

  • Comprehensive site surveys are essential in brownfield projects. As-built drawings are often unavailable or outdated, so existing services must be verified on site before MEP design begins.
  • Rigorous MEP coordination and clash detection must be embedded in the design stage. Early and continuous coordination across disciplines, supported by systematic clash detection, helps avoid costly rework during execution.
  • Available ceiling heights must be verified before service routing is finalized. Confirming actual ceiling voids on site ensures duct, pipe, and cable layouts are installable and code-compliant.

Frequently Asked Questions

What made this banquet kitchen renovation so challenging?

The service zone between the structural slab and the finished ceiling was restricted to just 2,500 mm, yet it had to accommodate HVAC supply and exhaust ducts, fire protection pipework, drainage lines, electrical containment, and structural obstructions. With original as-built drawings unavailable, clashes had to be found physically on site during execution.

How were MEP clashes identified without as-built drawings?

The team carried out site verification and service mapping, measuring actual clearances against the design assumptions. This on-site investigation revealed the clashes between HVAC ducts, fire protection piping, and drainage lines that were not visible in the issued Good for Construction drawings.

What false ceiling height was finally achieved?

By revising the HVAC duct dimensions, rerouting drainage and fire protection lines, and modifying the duct routing hierarchy, the required false ceiling height of 1,950 mm from finished floor level was achieved while preserving the specified airflow performance.

How were hotel operations protected during the works?

Disruptive works were scheduled on non-event days in coordination with hotel management, and planned shutdowns were used to connect refurbished exhaust and drainage services to the main network. This allowed controlled execution with minimal impact on live hotel operations.

What is a brownfield project in this context?

A brownfield project involves refurbishing or upgrading an existing, often operational, facility rather than building on a vacant site. Because the building is already in use—and its records may be incomplete—coordination, sequencing, and on-site verification become critical to avoiding disruption and rework.

Why is verifying ceiling height so important before routing services?

Confirming the actual ceiling void on site ensures that duct, pipe, and cable layouts are physically installable and code-compliant. When available heights are assumed rather than verified, service clashes and costly demolition or rework can follow—exactly the situation this project managed to avoid.
