SOLUTIONS FOR STRUCTURES
Building Envelope
for Existing Structures
Walker’s building envelope experts bring a practical consulting approach to each unique project and client. Whether it be cracking in masonry, spalling of concrete, fogging of windows, water or air infiltration, Walker can help pinpoint the cause and develop cost-effective solutions.
The building envelope and other barrier elements, is the primary line of defense against exterior elements and plays critical role in a building’s performance, occupant comfort, and aesthetics. Like any complex system, it needs requires assessments and maintenance throughout its service life. Engaging our building envelope experts early to routinely assess your structure’s building envelope is a proactive approach to avoid costly repairs later. However, in the event defects or deficiencies are identified in the building envelope, our experts have extensive forensics investigation experience and can help to identify the underlying cause of the issues, and design repairs to address them.
We combine emerging technologies with time-tested and proven methods to create solutions tailored to your needs, budget, and schedule.

Industrial Rope Access
Industrial Rope Access is an access method which allows qualified engineers and architects at Walker to safely access and work at elevated or difficult-to-reach areas. Walker uses industrial rope access to provide clients with cost-effective and efficient solutions for close-up and hands-on surveys without the added disruptions and expense associated with swing-stages, supported scaffolding, or aerial lifts. Elements of buildings and other structures surveyed by industrial rope access include exterior wall and sloped roof facades, vaulted interior spaces, and façades and structural framing of stadiums, monuments, bridges, spires and elevated water tank structures. Examples of services Walker performs with industrial rope access include:
