Evaluation of the Washington Monument, Washington, DC

Oehrlein & Associates Architects

The Washington Monument is the tallest and most visible monument in Washington, DC. It is a marble-faced obelisk 555’-5 1/8" tall, marking the center of the capital city. Its importance as a memorial, as a symbol of the Qty of Washington and as a feat of engineering is unsurpassed. The purpose of this study is to provide a general evaluation of the condition of the Washington Monument and to make recommendations for conservation of the building fabric. While many reports have been made in recent years focusing on specific aspects of the Monument, an overall assessment of its condition is needed. This study will provide an understanding of the current condition of the Monument and will serve as a guide for further work and study. The scope of work for this study requires that attention be paid to specific known problem areas. These areas include water infiltration problems in the Monument, structural evaluation of underground service areas, identification and recommendations for abatement of asbestos-containing materials and lead-based paint, the evaluation of the condition of stone, mortar, windows and sealants, and an evaluation of the settlement of the Monument. Topics not included in the scope of work are the site, the electrical system, the elevator, and finishes in the lobby and observation areas. This study includes a review of past studies of the Monument, a review of work performed on the Monument, and a description of the construction of the Monument. The interior and exterior condition of the Monument was surveyed and a year-long program of monitoring the interior environmental conditions was conducted. Recommendations for conservation and maintenance were based on the results. Recommendations include future studies, future monitoring and a prioritized outline of work which should take place.
