Our Design & Construct (D&C) Mechanical Engineering design services are delivered by Dewick & Associates’ Chartered Mechanical Engineering Team, providing specialist building services engineering support for contractors, developers, and project teams across complex construction projects.
We deliver practical, compliant, and cost-effective mechanical system design that ensures installations are buildable, coordinated, and aligned with regulatory and operational requirements.
Working across commercial, healthcare, education, defence, infrastructure, and high-performance building sectors, we provide delivery-focused mechanical engineering design services that bridge the gap between consultant design intent, contractor installation requirements, and compliance obligations.
Our approach reduces coordination risk, improves buildability, and supports efficient project delivery from concept through to construction.
Our D&C Mechanical Engineering services provide a comprehensive extension of your project team, supporting design development, coordination, calculations, and documentation required for compliant and efficient building services systems.
All design work is underpinned by Chartered Engineer expertise and extensive experience across mechanical building services, commissioning, and construction delivery.
We undertake detailed heating and cooling load calculations to assess building thermal performance requirements and ensure mechanical systems are correctly sized for occupancy, usage patterns, and environmental conditions. This supports efficient plant selection, optimised system performance, and reduced operational risk.
We provide specialist ventilation design and compliance assessments in accordance with AS 1668 Mechanical Ventilation Standards, including:
Our AS 1668 ventilation engineering services ensure systems meet Australian safety, air quality, and compliance requirements while supporting efficient and reliable building operation.
We provide ventilation design and compliance assessments in accordance with Approved Document F (Ventilation) UK Building Regulations, including:
Our Approved Document F services ensure ventilation strategies meet UK regulatory requirements for occupant health, safety, and building performance.
We undertake detailed static pressure drop calculations across air side and water side systems to ensure correct system balancing, optimised fan and pump selection, and reliable long-term mechanical system performance.
Provision of detailed equipment sizing and selection services based on calculated system loads and design requirements, including:
We prepare structured mechanical services schedules suitable for consultant review, contractor coordination, and project approval processes. These deliverables ensure clarity, accuracy, and compliance with design documentation and project specifications.
We develop clear, coordinated mechanical engineering specifications aligned with project requirements and regulatory standards. We also provide responsive engineering support for construction queries, coordination challenges, and ongoing design development throughout project delivery.
Our engineers support value management (VM) processes by assessing alternative design solutions and providing engineering input on cost, performance, and compliance impacts.
We also undertake detailed shop drawing reviews to ensure contractor submissions align with design intent, system performance requirements, and regulatory obligations.
Our D&C Mechanical Engineering design services are delivered by Chartered Engineers with recognised qualifications and professional registrations across Australia and the UK, including:
This ensures all mechanical design outputs are technically robust, regulation-compliant, and grounded in real-world construction and commissioning experience, giving contractors and developers confidence in buildability, performance, and compliance from design through to delivery.
