Building owners and managers turn to WJE when they need a firm that fully understands their building facade problems. WJE pioneered the practice of modern facade assessment and repair more than forty years ago. WJE’s work investigating landmark facade failures, including New York City’s Woolworth Building in 1977 and Chicago’s Aon Center in 1988, positioned the firm as a global leader in the field. Today, WJE is recognized as a trusted resource for objective and technically sound facade assessment and repair design on both contemporary and historic structures. 

One of the unique core strengths WJE brings to all of its work is the technical depth and expertise available from the firm’s materials science group in the Jack R. Janney Technical Center (JTC). More than sixty years of industry-sponsored, leading-edge research and laboratory testing for material durability and performance provides WJE professionals with the in-house resources necessary to take a holistic approach to problem-solving that is critical to developing comprehensive, cost-effective, and technically sound repair and restoration strategies for building facades of any age, material composition, or construction type. The technical depth of the JTC and hands-on approach to problem-solving that all of the company’s professionals take in the field are both hallmarks of WJE, whether working from scaffolding or engaging the services of the professionally certified WJE Difficult Access Team to reach facade and domed surfaces that others consider impossible to reach.
Using state-of-the-art testing equipment and laboratory capabilities, WJE professionals have successfully diagnosed and solved problems in thousands of building facades.

A WJE Advisory: Advantages and Disadvantages of Using Rope Access Techniques
On November 17, 2016, OSHA issued a final rule updating the fall protection requirements of the General Industry Rules 29 CFR 1910, known as Subpart D, Walking-Working Surfaces. OSHA’s General Industry Rules apply to maintenance work performed on or in existing structures and facilities. The new rules cover a wide array of conditions and hazards.

Notably, effective January 17, 2017, the use of rope descent systems for maintenance activities is now restricted to locations no higher than 300 feet above ground level unless it is not feasible to access such heights by any other means or if those means pose a greater hazard than rope descent. The burden for proving that no other safe and feasible method exists rests with the entity whose employees are performing the work via rope descent.

A new WJE Advisory shares the advantages and disadvantages of using rope access techniques to access the facades of buildings based upon our project experience in this area as well as discussions with building owners and window washing contractors.
