Lead Estimator
Farrukh has been a cornerstone of Denair HVAC's operations since 2010, bringing deep expertise in bid proposal preparation for complex commercial and medical facility HVAC projects across Brooklyn and NYC. He is responsible for crafting detailed, accurate proposals that reflect the full scope of work—including alternates, revisions, and value-engineering opportunities that can reduce project costs by up to 35%. His meticulous approach to tracking opportunities with vendors, subcontractors, and clients ensures that every medical facility receives a competitive, transparent, and fixed-price proposal tailored to their specific operational needs.
Hospitals and medical facilities typically use dedicated air handling units (AHUs) with HEPA filtration, precise humidity controls, and pressure-differential systems to prevent cross-contamination. Common configurations include central chilled water systems, variable air volume (VAV) systems, and VRF systems for specialized zones. All must comply with ASHRAE 170 ventilation standards and local NYC building codes to protect patients and staff.
