Design Fundamentals
What is HVAC Design & BOQ
At Abontika HVAC Engineering, we provide complete engineering and documentation services from load calculation and system selection to detailed BOQ preparation and tender support.
What is HVAC Design & BOQ?
HVAC design is the process of planning and engineering a complete heating, ventilation, and air conditioning system based on building requirements, usage, and environmental conditions. It involves load calculation, system selection, airflow design, and equipment specification.
BOQ (Bill of Quantities) is a detailed document that lists all HVAC components, materials, equipment, and quantities required for a project. It is essential for project costing, tender submission, and execution planning.
Accurate design and a disciplined BOQ keep the project buildable, costed, and commissionable.
Why HVAC Design & BOQ is Critical
In large HVAC projects, improper design or inaccurate BOQ can lead to system inefficiency, overdesign or underdesign, budget overruns, project delays, and operational issues. In Bangladesh's growing infrastructure and industrial sector, professional HVAC design services are essential for ensuring systems are technically sound, cost-effective, and aligned with project requirements.
