ABOUT THE SERIES
Historic buildings and structures can show signs of distress or damage, but require an investigation to understand the root cause of the issue. We use forensic engineering investigative techniques for various types of construction and building materials to diagnose problems and ultimately develop appropriate repair and restoration solutions. Through case studies, we will illustrate example investigations and discuss the benefits of forensic engineering. Case studies will include historic stone masonry, terra cotta and steel structure, exposed concrete, and copper-clad dome projects. This presentation is the precursor to our upcoming repair and rehabilitation deep dive topic series, which will focus on specific material investigations and remediation options.
R+R EVENING SEMINAR 2:
Mass Masonry Walls: Investigating and Repairing
Presented by Peter Babaian
Tuesday, May 16, 2017
Mass masonry walls were the common building structure prior to the introduction of the internal structural steel frame. These walls served a dual purpose – they comprised the building structure as well as the building enclosure. Therefore they need to resist building loads while keeping water out, heat in or out, and air infiltration/exfiltration to a minimum. Mass masonry buildings that remain are often designated landmarks, which makes repairs to these buildings challenging. Well-developed repairs will balance the aesthetic and performance needs of the building.
R+R EVENING SEMINAR 3:
Steep Slope Roofs: Investigating, Repairing, Recovering, and Replacing
Presented by Emily Whitbeck O’Keefe
Tuesday, May 30, 2017
Steep slope roofs can be a defining architectural feature of a building and include a variety of materials, such as asphalt shingles, slate, wood shakes, metal, and single-ply membrane. These architectural features can make access to steep slope roofs difficult and conceal ongoing deterioration. Although steep slope roofs shed water quickly, they still deteriorate over time due to multiple factors, including environmental damage, inadequate drainage, improper waterproofing transition details, and natural material degradation. Proper investigation and assessment of roof deterioration is necessary to understand underlying performance issues. It is also important to understand the root deterioration causes and required current building codes to develop proper approaches to remediation.
R+R EVENING SEMINAR 4:
Concrete Deterioration Mechanisms: How and Why?
Presented by Kevin Conroy
Tuesday, June 13, 2017
Reinforced concrete is a durable material when properly designed, installed, and maintained. Despite this durability, deterioration can rapidly occur, making repairs necessary. Deterioration caused by improper design, substrate preparation, mixing, placing, and curing of the concrete can present itself as cracks, spalls, and curling. Material mechanisms can also cause deterioration, including corrosion of internal reinforcement accelerated by carbonation or increased chlorides, reactive aggregates, delayed ettringite formation, and sulfate attack. Proper diagnosis of the underlying deterioration mechanism is essential for repair performance. Treating only the symptoms will likely result in repairs that fail prematurely, requiring “repairs to the repairs.” Through proper investigation, it is possible to identify the deterioration mechanism and develop appropriate repairs.
Punched window systems are discrete windows located within an opaque building enclosure assembly. Problems associated with punched windows can be the result of window material deterioration or integration issues with the surrounding building enclosure systems. Determining an appropriate repair requires an understanding between these two types of failures. Water, air, and materials testing can help identify the failure mechanisms. Once the failures are categorized, repair or replacement options can be developed to target the identified failure. When repairing or replacing punched windows, considerations related to cost, time, materials, disruption, and existing codes are all factors that affect the final design and performance.
