The Greenbrier Historical Society (GHS) requests proposals from qualified masonry contractors to provide services to repoint the 1834 Supreme Court of Appeals of Virginia Law Library and Study building, also known as the “Pink Library”, in Lewisburg, West Virginia. Interested contractors must submit a written or electronic proposal by 3:00 pm on Friday, November 18, 2022, to Al Emch, Greenbrier Historical Society (alemch235@gmail.com; 814 Washington Street, Lewisburg, WV 24901). The “Pink Library'' was built in 1834 and is listed on the National Register of Historic Places. The building is in need of selective masonry rehabilitation due to water intrusion from faulty gutters and downspouts and the application of a latex paint over brick. This project is funded in part by Preservation Alliance of West Virginia in partnership with the Paul Bruhn Rural Revitalization Grant provided by the National Park Service. As such, the Secretary of the Interior's Standards for Archaeology and Historic Preservation must be followed. A mandatory pre-bid meeting will be held at 11:00 am on Wednesday, November 9, 2022. The project will include:
Add-Alternate pricing is requested for the following:
Contractors must meet the following qualifications and submit the following:
Contractor selection will be based on experience, proven ability to complete a project and cost. All proposals must provide 30 days for acceptance from the due date. The GHS and PAWV reserves the right to reject any and all proposals and to waive minor administrative oversights. The contractors will be reimbursed for services rendered up to the contract amount. All changes in scope must be pre-approved by the GHS and PAWV. Contractors will not be reimbursed for travel expenses, or any costs incurred in preparation of this proposal. The contractor will be paid in increments based on satisfactory completion of specific stages of the project. The balance will be paid after approval of the work by the Preservation Alliance of West Virginia. Mortar Analysis Pink Library Lewisburg, West Virginia August 22, 2022 On Thursday, August 18, 2022, David Arbogast, architectural conservator, of Davenport, Iowa received a mortar sample from Sandra Scaffidi of Practical Preservation in Fairmont, West Virginia. The sample was taken from the Pink Library in Lewisburg, West Virginia and was submitted for analysis to determine its composition.
The analysis commenced on Saturday, August 22, utilizing the acid digestion testing procedure developed by E. Blaine Cliver, former Regional Historical Architect of the North Atlantic Region of the National Park Service. This relatively simple procedure dissolves the lime and/or cement content of the mortar using a 20% solution of hydrochloric acid. The carbon dioxide released as a result of the reaction displaces water, which is then measured and used to calculate the soluble content of the mortar. The insoluble fines and sand remaining from the reaction are factored into the equation resulting in a final result. In the case of cement samples, the remaining fines are used to calculate the cement content of the mortar. The remaining sand is then carefully sieved and graded by grain size to provide a means of identification of the various sand types encountered. The sample was brown and exceedingly soft in its consistency. It had a fast and foamy reaction which resulted in a moderate water displacement. The sample filtered rapidly with the filtrate color being the typical yellow-green. There was an exceedingly large proportion of brown fines. They most likely were dirt. All of the aforementioned attributes are indicative of mortar consisting of lime and sand only. The sand sieve analysis revealed very fine sand. All of it passed through the largest sieve with nearly exactly 3/5% stopped in the second largest sieve. Some of it was present in the third largest sieve, although not enough to register any weight with almost exactly 1 3/4% caught in the fourth largest sieve. A smidgeon more than 19 2/5% remained in the finest sieve with just less than 78 1/4% travelling through all the sieves to the base.
