Spatial Planning & Programming
Laboratory Planning & Design Consultancy
Effective laboratory design begins with a meticulous understanding of scientific processes, personnel workflows, hazardous material storage, equipment logistics, and biosafety protocols. We work collaboratively with laboratory owners, principal researchers, and project architects to translate complex programmatic requirements into efficient, flexible, and fully compliant physical layouts.
Workflow Analysis & Spatial Programming: Segregation of clean and contaminated zones, sample flow optimization, and personnel movement mapping.
Biosafety & Containment Zoning: Detailed space layout in strict compliance with BSL-1 through BSL-3 criteria, anterooms, and barrier separation.

Future Adaptability & Modularity: Overhead service distribution carrier design, flexible plug-and-play benching systems, and demountable partitions.
Laboratory fume hoods are essential engineering safety systems designed to protect laboratory personnel from exposure to hazardous chemical vapours, gases, fumes and airborne contaminants generated during laboratory operations. Our solutions combine airflow engineering, effective containment technology, ergonomic design and durable construction to create safer and more efficient laboratory environments.
From conventional chemical fume hoods to advanced variable air volume (VAV) systems, we develop solutions around application-specific safety, performance and operational efficiency.
Engineered Containment: Aerodynamic sashes, calibrated baffle geometry, digital airflow monitors, and continuous face velocity containment.
Fume Hood Configurations Covered
Conventional Laboratory Fume Hoods
General-purpose chemical fume hoods for routine chemical handling, sample preparation, and standard experimental protocols.

Chemical-Resistant Interiors: Solid phenolic resin, epoxy resin, ceramic, or seamless polypropylene liners selected according to chemical compatibility.
BMS Integration: Full protocol compatibility with building management systems via BACnet MS/TP, BACnet IP, or Modbus interfaces.
Laboratory safety is not an operational afterthought; it must be engineered directly into the architectural layout, ventilation balancing, utility distribution, and emergency infrastructure. We provide structured risk assessments and engineering reviews that safeguard researchers and facility assets against chemical, biological, and physical hazards.
Hazard Identification & Chemical Incompatibilities: Segregated storage planning for flammables, acids, oxidizers, and toxic gases in accordance with NFPA 45 and OSHA standards.

Differential Pressure & Directional Airflow: Calculation of cascades to ensure hazardous rooms remain continuously negative relative to clean corridors.
Compressed & Toxic Gas Safety: Gas detection sensor layout, automatic emergency shut-off valve integration, and gas cylinder bunker ventilation design.
Laboratories consume between 4 to 10 times more energy per square meter than typical commercial office buildings due to 100% outside air once-through ventilation, continuous fume hood exhaust, and intensive plug loads. Our sustainable engineering consultancy identifies targeted energy conservation measures (ECMs) that dramatically lower carbon footprint and operating expenditure without ever compromising containment safety.
Variable Air Volume (VAV) Optimization: Establishing dynamic sash setback strategies and occupancy-based air change rates (ACH) safely reducing exhaust volume.

The mechanical, electrical, and plumbing infrastructure of a laboratory represents the largest share of facility complexity. We act as the technical coordinator bridging the specialist laboratory requirements and the core MEP engineering teams, ensuring clash-free spatial distribution and synchronized performance.
Laboratory Exhaust Ductwork Engineering: Specification of welded 316L stainless steel, FRP, or coated galvanized steel ductwork routing to minimize pressure drops and eliminate chemical accumulation pockets.
High-Plume Dilution Blowers: Induced-flow fan selection ensuring exhaust plume height safely disperses above building boundary layers and rooftop air intakes.
Clean & Process Utilities Coordination: Technical piping sizing for High Purity Gases, RO/DI deionized water, central laboratory vacuum, and compressed dry air (CDA).
