Engineering Services

Tenants may need special engineering services, including repairs to private bathrooms, replacement of non-standard ceiling tiles, and installation of additional thermostats. The tenant is billed at established rates for engineering services. Please enter all request for services via the Angus work order system.

Engineering requests are processed and billed as follows:

  • A member of the engineering department staff investigates the situation
  • If possible, the problem is resolved immediately
  • If materials must be purchased or completing the repair requires further planning or other assistance, the engineer consults the Property Manager. They then plan the work and prepare a time-and-materials estimate for tenant approval

Prior to work commencing, the tenant will be required to acknowledge the cost of work for which the tenant is responsible.
