Elevating Your Facades to Maximise Building Performance



The first step in building rehabilitation is to gain an understanding of the underlying conditions and existing elements of the building. These building assessments can:

  • Diagnose specific issues related to air and water intrusion into the existing building enclosure
  • Provide property condition reports on the current condition recommended maintenance and replacement cycle
  • Contribute to CapEx studies, reserve studies and point of sale due diligence
  • Assess the building’s structure for the feasibility of proposed changes

Our recommendations inform the contractor to provide an initial estimate for the work required. Lerch Bates guides our clients through this initial phase to set the stage for repairs that fit the budget and maximise the benefit to the building.

Once construction is underway, Lerch Bates supports our clients throughout the bidding phase. Identifying the best team to execute the design on time and within the budget is essential to keep the project moving. Once the project is under contract, we transition into construction administration. During this phase, Lerch Bates can:

  • Review product and shop drawing submittals
  • Respond to questions and RFI’s
  • Participate in progress meetings
  • Conduct onsite quality assurance observations

This continued monitoring throughout construction allows our team to report on any observed construction that does not meet the intent of the design and provide solutions in real time.
