    APT DC presents a hard hat tour of The Wren Building with Constance Lai, FAIA, Grunley Construction, and Susan Reed, AIA, principal and director of historic preservation, Glavé & Holmes.

    The Sir Christopher Wren Building at William & Mary is the oldest college building still standing in the United States and the oldest of the restored public buildings in Williamsburg. It was built between 1695 and 1700.

    The Wren Building has been gutted by fire three times — in 1705, 1859 and 1862. Each time the interior of the structure was rebuilt. For more than three hundred years, it has been "the soul of the College." Generations of William & Mary students have attended classes and lectures, enjoyed meals and attended chapel services in the Wren Building. The building will continue to be occupied throughout construction.

    The current project includes repairs and replacement of the foundation drains, wood cornice, and clay tile roof. The façade restoration includes repointing with lime mortar, brick stitching repairs, and brick replacement. The stair restoration scope includes repairs to the metal railings, Portland stone treads, brick foundations, pavers, and drainage elements.

    Two (2) AIA LU | HSW Credits are available for this event. Please select this during registration and provide your AIA #.

    The tour will start at the east entrance of the Wren Building. See: https://maps.app.goo.gl/n7a9GDB9StUoHthaA

    Please note: Limited to 20 people. Please wear pants (no skirts or dresses) and sturdy shoes. If possible, bring your hard hat, safety vest, and eye protection. We will have some Personal Protection Equipment (PPE) to share. If you need to borrow PPE, please email info@aptdc.org. Each tour will include climbing scaffolding up several stories.

    The Washington, DC Chapter of the Association for Preservation Technology is pleased to announce its Fall 2025 Symposium. This year's theme is Unforeseen Conditions.

    Adaptability is key to the success of projects involving rehabilitation of historic sites, as Unforeseen Conditions have the ability to derail even the most carefully laid plans. These unforeseen conditions can take a variety of forms, such as concealed conditions or features, or unknown previous alterations. They can also take the form of newly discovered treasures including previously unknown historical documentation found in an archive or buried and long forgotten historical artifacts.

    The methods for handling these unforeseen conditions are as varied as the conditions themselves, often requiring unique and creative solutions. This symposium will focus on unique challenges with unforeseen conditions including:

    • What was the discovered unforeseen condition and in what context was it found?
    • How was the unforeseen condition investigated?
    • How did the unforeseen condition affect the progress or direction of the project?
    • What creative solutions were developed to handle the unforeseen condition?
    • How will this experience inform planning for a similar unforeseen condition in the future?

    The presentations include:

    • Case studies of preservation projects with significant unforeseen conditions.
    • Application of new or novel technologies and techniques in the handling of unforeseen conditions.
    • Compelling lessons learned and recommendations. 

    The symposium will include eight (8) paper presentations, a walking tour, and an optional happy hour.

    Registration will open on August 5, 2025.
