Mechanical and HVAC
Maintain optimal environmental controls for your personnel and equipment. We install and upgrade high-capacity climate systems with minimal operational interference.
Upgrade your mechanical systems
Overview
Climate control for secure facilities
Jaws builds complex mechanical and environmental systems from the ground up inside active defence sites, as well as upgrading existing plant. We know that your hardware requires exacting temperature and humidity controls to function correctly. Our teams execute large-scale HVAC replacements and ducting modifications while expertly managing the strict spatial and security constraints of your classified buildings.
Equipment protection: We ensure your sensitive technical assets remain at optimal operating temperatures.
Confined space expertise: Navigate complex existing structures to route new mechanical infrastructure safely.
Synchronised changeovers: Transition to new climate systems without exposing your facility to environmental risks.
Scope includes
- High-capacity HVAC replacement
- Precision cooling for technical spaces
- Ductwork design, fabrication and modification
- Chilled water and hydronic systems
- Ventilation and pressurisation works
- Controls integration and commissioning
How we deliver
Delivery approach
We specialise in the physical installation and construction of mission-critical environmental systems, turning engineering specifications into robust, high-performance infrastructure built from the ground up.
Environmental risk and site assessment
We conduct rigorous site evaluations prior to mobilisation to map material handling routes, spatial constraints and integration points for heavy plant. Our project managers then set precise construction sequencing so structural, mechanical and containment works align without compromising site security.
Structural containment and room build-out
We construct and install rigid hot and cold aisle containment, secure technical rooms and structural framing for high-density thermal management, sealed with certified fire-rated, acoustic and environmental penetration seals.
Mechanical plant and infrastructure installation
We install large-scale plant including chillers, precision CRAC/AHU units, pumps and extensive pipework, along with complete assembly of duct systems, plenums and air delivery pathways engineered to optimise airflow.
System interface and mechanical fitting
Our experienced electrical teams tie environmental equipment into critical power distribution and BMS wiring, with safe rigging, positioning and mounting of heavy cooling infrastructure and supporting framework.
Commissioning support and handover
We support pressure testing, flushing and mechanical balancing of all piping and air distribution, backed by comprehensive as-built and compliance documentation so your infrastructure is ready for operational commissioning.
Common questions
What clients ask
Can equipment stay online during the upgrade?
In most cases yes — we use temporary environmental controls and staged changeovers to avoid exposure.
Do you work in confined and restricted spaces?
Yes. Confined space and restricted access works are routine for us and covered by our safety governance.
