BMS Maintenance in London & the South East

Parsek Group provides planned BMS maintenance for FM companies, M&E contractors and building owners across London and the South East. Each visit follows a documented scope, is carried out by a Niagara 4 and Distech certified engineer, and ends with a written report you can pass straight to your client.

What a maintenance visit covers

  • Supervisor and front end – supervisor health, licensing, disk space, devices online, user accounts and graphics showing live, sensible values.
  • Controllers and panels – visual inspection, power supplies and 24V transformers, controller clocks, BACnet and Modbus network health.
  • Sensors and field devices – spot checks against a calibrated reference, 4–20 mA and 0–10V signal tests, valve and damper actuators stroked, drives checked for command and feedback.
  • Alarms – alarm history reviewed, nuisance alarms dealt with at the root cause, critical alarms tested through to the people who need to receive them.
  • Schedules, setpoints and overrides – time schedules compared with real occupancy, holiday calendars loaded, plant left in hand found and released.
  • Trends and energy – trend logs reviewed for hunting loops, short-cycling and simultaneous heating and cooling; meters checked for reading and logging.
  • Backups and documentation – full supervisor and controller backups taken and stored off site, points lists and descriptions of operation updated after any change.

The full scope is set out in our BMS maintenance checklist.

Planned maintenance (PPM) contracts

Most commercial buildings need at least one full BMS service a year. Larger, busier or critical sites such as comms rooms and healthcare are better served by quarterly or six-monthly visits. We agree the visit frequency and scope with you up front and quote a fixed price per visit or per year, so the cost is known before the contract starts.

  • Fixed scope and fixed price, agreed before the first visit
  • Written service report after every visit: findings, actions taken and recommendations
  • Backups and sensor checks included on every visit
  • RAMS provided for every site
  • Reactive fault-finding available between planned visits

Systems we maintain

  • Tridium Niagara 4 supervisors and JACE controllers – TCP certified
  • Distech Controls EC-Series – certified
  • Third-party plant integrated over BACnet/IP, BACnet MS/TP and Modbus RTU/TCP
