Confiden ality: Informa on developed under this contract shall not be shared and will be kept in strict confidence.

Project Iden fica on: The work of this project shall consist of the services described below for the referenced project. In all related documents, the project shall be referred to Historic Window Restora on and Proof of Concept, Brown v. Board of Educa on Na onal Historical Park.

BACKGROUND

Brown v. Board of Educa on Na onal Historical Park preserves 3.15 acres of land including the former Monroe Elementary School at 1515 SE Monroe Street in Topeka, Kansas. The Monroe School was one of four segregated elementary schools in Topeka for Black children. It opened in 1927. The park commemorates the landmark 1954 United States Supreme Court decision in Oliver Brown et al. v. Board of Educa on, which unanimously ruled that segrega on of children in public schools by race was uncons tu onal. In 1992, President George H.W. Bush signed legisla on crea ng Brown v. Board of Educa on Na onal Historic Site and in 2004, the park opened to the public on the 50th anniversary of the landmark ruling. In May 2022, President Joseph R. Biden signed the Brown v. Board of Educa on Na onal Historical Park Expansion and Redesigna on Act, which renamed and expanded the park’s boundary in Topeka, KS; added a new park unit in Summerton, SC; and created five affiliated areas in Delaware, Virginia, and the District of Columbia.

PROJECT METHODS

There are 91 total openings with steel casement windows. There are 369 sashes. This project includes only one opening: the large window unit on the south end of the second floor. The glass was replaced prior to 2004 and is 1/8” clear glass.

Experts in historic windows made these technical observa ons and condi on assessments in 2024:

Windows are a subframe, frame, and sash design with slider stay open arms.

Failing perimeter sealant where the windows meet the masonry.

Openings are currently covered with interior aluminum storm windows. Storm windows are impac ng the overall beauty of the building in an effort to gain energy efficiency. Storm windows are not ven ng correctly and crea ng a moisture containment issue.

Each observed opening showed significant rust. Rust has penetrated behind both the frames and subframes of each window. If the rust is not removed from all sides of the window components, it will come back in ma er of years.

Sash and Frames have been altered to remove an upper stay open arm, but the holes le behind were not filled and water is entering through those holes.

Observed mul ple areas many units where water is penetra ng the unit.

Glass is currently glazed with a silicon product in a manner to emulate a pu y glaze, but the product was designed for the applica on and is failing. Complete glazing failure observed on mul ple lites.

Individual glass panes are 1/8” clear glass and measure about 10 3/16” x 12 ¼”.

Sash hinges a ach to the frame between the frame and the masonry.

In par cular, these condi ons were noted for the proposed unit to be removed and restored in this project:

• Steel triple-casement transoms—paint in fair condi on; frame in fair condi on; sash in fair condi on; hardware in fair condi on; glazing in poor condi on; stone sill in fair condi on; interior plaster in fair condi on; overall in fair condi on. Also, frame/sash corrosion is present with moisture present at the plaster; glazing sealant/pu y is in need of full replacement.

The treatment report recommended that a proof of concept (POC) mockup be completed on one unit.

The window unit in ques on is the second-story unit in the photo below:

Approximate interior measurements of the window unit:

69.5 inches W x 86.5 inches H

DELIVERABLES

Deliverables for the project will include:

A proof of concept (POC) mockup of one window unit.

The unit will be removed from its opening for restora on offsite. This includes sash, frame, subframe, and hardware on the opening.

The opening will be covered securely with ¾” OSB Plywood and anchored to the building in such a way as to not disturb the historical fabric of the building.

All finishes and rust will be removed from the window unit offsite a er removal of the window from the building.

All unused penetra ons will be filled and repaired using epoxy fillers. This applies to holes in the metal frames from previous uses.

The window sash will be glazed with new or recovered glass units. The contractor will maintain the historical design of the windows while inves ga ng whether more energy-efficient glass can be installed in place of the exis ng glass.

Painted finishes will be removed from hardware, which will then be cleaned and polished.

Window sash, frame, and subframe will have shop-applied high performance steel finish. The contractor will consult with the NPS with specific product recommenda ons a er the paint and rust are removed and the unit is available for complete documenta on and inspec on of condi on.

The restored window unit will be re-installed in its opening and sealed to the masonry.

The contractor will recommend whether storm windows should be retained or modified.

The contractor will document with high-resolu on photography every step of the POC mockup.

This includes a comparison to the windows as installed to the architect’s drawings of them from 1926. (See image provided below).

All digital data will be delivered on a flash or external drive.
