I require a qualified/experienced HVAC / Mechanical Services Engineer to prepare a practical and economical air-conditioning and mechanical ventilation design for a small single-storey medical/dental clinic in Vineyard, NSW, Australia. The existing building is approximately 103 m² and is being converted into a medical/dental clinic. The architectural floor plan will be provided. It includes Waiting/Reception, GP Doctor room, Dental Surgery, X-Ray, Sterilisation, Stores, Corridor and Accessible WC. The approved architectural drawing already requires the toilet to have mechanical ventilation ducted to the exterior. The intention is to use one ducted split air-conditioning system, if practical, with approximately two zones. A preliminary capacity of 14–16 kW has been considered, however the designer must perform the appropriate heat-load calculation and determine the correct capacity. Some windows located within 3 metres of the property boundary will be replaced with fixed/sealed glass blocks and therefore must not be relied upon for natural ventilation. Required deliverables: Heat-load/cooling and heating calculations and recommended AC capacity. Ducted AC layout showing indoor and outdoor unit locations. Supply-air and return-air duct layout and sizing. Supply diffusers and return-air grille locations and air quantities. Calculation of the minimum required outside/fresh-air ventilation for each relevant space in accordance with NCC 2022 and AS 1668.2. Economical method of introducing outside air into the ducted AC system where compliant. Accessible WC mechanical exhaust design and exhaust-air quantity. Fresh-air intake/exhaust locations, fans, filters, grilles/louvres and duct sizes. AC zoning and controls. Equipment/fan/diffuser schedule sufficient for Australian contractors to quote and install the system. Mechanical drawings suitable for tender/construction. Relevant design calculations and compliance statement/documentation. The objective is not a sophisticated commercial HVAC system. Because of uncertainty surrounding a possible future TfNSW road-widening/acquisition project, capital expenditure needs to be kept as low as reasonably possible. I therefore want the simplest, lowest-cost design that properly complies with NCC 2022, AS 1668.2 and applicable Australian Standards. Where practical, preference would be for a simple arrangement such as: Filtered outside-air intake → appropriately sized fresh-air fan → ducted AC system → occupied rooms with a separate WC exhaust system, provided this can satisfy the applicable requirements. Please include with your offer Please confirm your experience designing HVAC systems to Australian NCC/AS requirements, particularly AS 1668.2; your engineering qualifications; examples of similar Australian projects; exactly what drawings/calculations will be supplied; whether you can provide Australian mechanical design certification suitable for NSW CC/Occupation Certificate purposes; fixed fee; and turnaround time. Important: Please do not bid if you can only produce an AutoCAD duct layout without carrying out the required HVAC load and NCC/AS 1668.2 ventilation calculations.

Hello, I am interested in assisting with the HVAC/mechanical design for your 103 m² medical/dental clinic in Vineyard, NSW. I understand that this project requires more than a duct layout. The design must include the actual heat-load calculations, correct AC capacity selection, outside-air requirements, WC exhaust, duct sizing, air quantities, equipment selection and compliance with NCC 2022 and AS 1668.2. My proposed deliverables would include: * Cooling and heating load calculations * Recommended AC capacity * Ducted split AC layout with indoor/outdoor unit locations * Supply and return duct sizing/layout * Diffuser and return-grille schedule with airflow quantities * Fresh-air ventilation calculations for applicable rooms * Economical compliant outside-air introduction arrangement * Accessible WC exhaust calculation and layout * Fresh-air intake/exhaust locations, fans, filters, grilles/louvres and ductwork * Zoning and controls * Equipment and diffuser schedules * Tender/construction mechanical drawings * Calculation and compliance documentation I would specifically aim for the simplest and most economical compliant solution rather than over-designing the clinic, while accounting for the sealed windows and the requirements of the applicable Australian standards. Please send the architectural DWG/PDF and I can review the layout .

Hello, I have experience preparing HVAC and mechanical ventilation designs for small commercial and healthcare spaces, including heat-load calculations, duct sizing, outside-air ventilation, exhaust systems, zoning, and equipment schedules. I am a good fit because I can develop a simple, economical system while coordinating the design with NCC 2022 and AS 1668.2 requirements. I will calculate the actual heating/cooling loads, verify whether one ducted split with two zones is practical, and design the supply, return, fresh-air, and WC exhaust systems with required air quantities and duct sizes. I will provide mechanical plans, schedules, calculations, controls, intake/exhaust details, and compliance documentation suitable for contractor pricing and construction. I do not personally hold the required NSW mechanical certification, but I work with appropriately qualified Australian engineers who can review and provide certification where required.

Dear Client, I can prepare the complete HVAC and mechanical ventilation design for your 103 m² Vineyard medical/dental clinic, with emphasis on a simple, economical system rather than merely producing a duct layout. The scope will include room-by-room heating/cooling load calculations, verification of the proposed 14–16 kW ducted split concept, zoning, supply/return air quantities and duct sizing, diffuser locations, outside-air calculations, WC exhaust, intake/exhaust locations, fans, filters, controls, and equipment schedules. I’ll develop the design around NCC 2022 and AS 1668.2 requirements, accounting for the sealed boundary-side windows and evaluating the proposed filtered outside-air fan arrangement as the preferred low-cost solution where compliant. Deliverables will include coordinated tender/construction drawings, calculation sheets, schedules, design criteria, and compliance documentation suitable for contractor pricing and project coordination.

Hello, I reviewed your medical/dental clinic HVAC requirements, and the key challenge is developing the lowest-complexity compliant system while accurately addressing heat loads, fresh-air requirements, zoning, and mechanical exhaust under NCC 2022 and AS 1668.2. I would calculate the heating and cooling loads first, determine the appropriate ducted system capacity, then develop the supply/return and outside-air strategy, WC exhaust, equipment schedules, controls, and coordinated tender/construction drawings with all required calculations and compliance documentation. I have worked on similar Australian HVAC, mechanical ventilation, NCC, and AS 1668.2 design projects and can share relevant examples and qualifications once we connect in chat. Also a quick question, do you already have the architectural floor plan with room areas, ceiling heights, occupancy assumptions, and window details available for the initial load and ventilation assessment?

This is exactly the type of HVAC design where correct calculations matter more than simply drawing ducts. I can develop a practical, cost-conscious mechanical design for your 103 m² medical/dental clinic, based on the architectural plan and Australian requirements. I’ll carry out the cooling/heating load calculation to establish the actual AC capacity rather than assuming 14–16 kW, then develop the ducted AC/zoning arrangement, supply & return air distribution, diffuser quantities, and equipment schedule. For ventilation, I’ll calculate the required outdoor-air rates for each relevant space in accordance with NCC 2022 and AS 1668.2, including the WC exhaust, fresh-air intake/exhaust arrangement, fans, filters, grilles/louvres and duct sizing. I’ll also assess the proposed economical fresh-air integration and ensure the design is practical for Australian contractors. The final package can include construction/tender drawings, calculations, schedules and compliance documentation, subject to the certification requirements applicable to the project. Please send the architectural floor plan and I can review the scope and confirm the fixed fee, deliverables, certification pathway and turnaround. Best Regards, Sumit Kumar
