Review
Drawings, BOQ, RFQ, site notes, equipment schedules, specifications, and missing information.
From project requirement to site-ready HVAC execution.
Most HVAC work does not begin with a perfect drawing. It begins with RFQs, BOQs, equipment schedules, site notes, sketches, revisions, and questions. BAF helps project teams convert that information into a clear ductwork, fabrication, installation, or documentation scope.
Plan
Material, thickness, routing, fittings, access, fire-rated needs, installation constraints, and delivery sequence.
Fabricate
Duct sections, fittings, transitions, plenums, collars, dampers, access doors, supports, and custom pieces.
Coordinate
Site installation, equipment connections, inspection readiness, testing support, and handover documentation.
Ductwork Systems
Custom-made ductwork systems based on material, purpose, and project requirement.
Every HVAC job has different demands for airflow, fire rating, insulation, pressure, routing, access, and installation. BAF supports GI, MS, and PI ductwork, with fire-rated or non-fire-rated scope applied according to the project specification.

GI Ductwork
Galvanized iron ductwork is the most common duct system for standard HVAC and ventilation work. It is used across comfort cooling, fresh air, return air, exhaust, and general air-distribution systems.
BAF supports GI ductwork from quantity takeoff and fabrication planning through manufacturing, fittings, accessories, and site-ready delivery.

MS Ductwork
Mild steel ductwork is used where stronger construction, welded fabrication, kitchen exhaust, smoke extract, fire-rated scope, or industrial ventilation is required.
In areas with grease, heat, smoke, or safety requirements, the duct system has to be treated as a technical safety element. Material thickness, welding, access doors, cleaning access, insulation, coating, and applicable project standards all matter.

PI Ductwork
Pre-insulated duct systems combine duct and insulation into one assembly. Instead of fabricating a metal duct and insulating it later, PI ducts are built from insulated panels with protective facings.
PI ducts can help reduce weight, speed up installation, improve thermal performance, and reduce separate insulation work. They are not automatically fire-rated. PIR, PUR, and phenolic systems each have different properties, and final suitability depends on project specifications, approvals, and test documentation.

Fire-rated and non-fire-rated ductwork are not separate from the ductwork architecture.
They are performance requirements applied to the right duct system. A project may call for GI, MS, PI, coated steel, wrapped systems, or authority-approved assemblies depending on smoke extract, kitchen extract, pressurization, basement ventilation, shaft crossing, or standard comfort HVAC needs.
Duct Fittings, Accessories & Air-Side Components
The catalogue direction is important here: ducts are not just straight boxes. A usable HVAC package depends on fittings, access, transitions, dampers, collars, hoods, plenums, and site-specific fabricated pieces.
Fabricated fittings for real site conditions.
Fittings control how the duct system turns, reduces, branches, connects, isolates, and remains serviceable. Poor fitting coordination can create leakage, noise, access problems, installation delays, and commissioning issues.

HVAC Equipment Installation
Installation support where ductwork meets equipment.
Ductwork only performs correctly when it is properly connected to the right equipment and coordinated with the rest of the HVAC system. BAF supports installation and interface work for AC units, FCUs, AHUs, FAHUs, exhaust fans, ventilation equipment, and duct-to-equipment connections.
Important details include equipment placement, service access, vibration control, condensate drainage, pipe interfaces, electrical coordination, flexible connectors, transitions, plenums, and commissioning readiness.

Chilled Water & Large HVAC System Support
Large HVAC projects where ducts, equipment, piping, and controls meet.
In larger buildings, chilled water systems move cooling from the plant to terminal equipment such as AHUs and FCUs. BAF's role is strongest where the air-side and installation coordination touch this larger system.
This includes AHU and FCU ductwork connections, coil access, equipment clearances, valve and piping interface awareness, condensate drainage, rooftop ductwork, plant room ductwork, and commissioning readiness.

Duct Testing, Commissioning & Handover Support
Verifying the system before it becomes part of the building.
A duct system can look complete and still have leakage, access problems, damper issues, poor airflow, or inspection comments. BAF supports testing and handover activities where required by the project scope.

Submittals & Project Documentation
Documentation that helps contractors, consultants, and procurement teams review the scope.
In HVAC and MEP projects, documentation is how the project team understands what is being supplied, fabricated, installed, inspected, and handed over. BAF supports material submittals, method statements, capability documents, product catalogue pages, BOQ/RFQ review, production records, delivery notes, testing records, and handover support.
