Alterations to tenant suites require the approval of the management office. Requests to make alterations should be sent in writing to the Property Manager. Only contractors approved by the management office can perform alterations. All construction contractors including general, electrical, plumbing and phone contractors must register with the management office at least one week prior to performing any work in the building. Installing or maintaining systems that affect the building’s infrastructure, such as HVAC equipment, electrical, or communication equipment, computer or alarm systems, power or fire protection, must also be coordinated with and approved by the management office.
