Scope of works

Each stream is delivered as a complete package — selection, supply, installation, testing and documentation — or as labour-and-supervision against your supply.

01

Building management systems

Field devices, DDC and IO panels, valve and damper actuation, BACnet and Modbus integration, graphics, alarm and trend configuration, and integration of HVAC, electrical and fire systems into one head-end.

02

Metro & infrastructure

Environmental control for underground and elevated stations, tunnel ventilation interfaces, depot and workshop systems, technical rooms and station control rooms — executed to rail-sector documentation and safety discipline.

03

Ventilation

Basement and car park ventilation, staircase pressurisation, smoke extract, commercial kitchen exhaust, industrial extract and fresh air treatment units.

04

Chiller plants

Air- and water-cooled chilled water systems: plant room layout, primary and secondary pumping, headers, cooling towers, valving and insulation.

05

Air conditioning

VRF and VRV systems, ductable splits, AHUs and FCUs, precision units for server and signalling equipment rooms — sized off heat load calculations, not rules of thumb.

06

Duct installation

GI ducting fabricated and erected to SMACNA gauges and sealing class, with supports, dampers, grilles, diffusers and thermal or acoustic insulation.

07

Clean rooms

Controlled environments for pharma, electronics and healthcare: HEPA terminal filtration, pressure cascade, panelling interface and validation support.

08

Site AMC

Comprehensive and non-comprehensive maintenance contracts — scheduled servicing, breakdown response, spares, BMS trend review and periodic performance logging.

What comes with the bid

Main contractors carry the risk of a subcontractor who cannot produce paperwork at handover — and on metro and public infrastructure packages that paperwork is audited. Every package we quote includes the full document set, priced in, not raised as a variation later.
