1 BACKGROUND

San Cristobal Outworks Guardhouse storage room and restrooms are in bad conditions.

Currently, restrooms remain closed, due to water and sewer problems. Restrooms are in a deteriorated state: structure has significant structural damages, biological growth is present in the walls, and tiles have weathered appearance. Plumbing repairs and/or replacements need to be conducted, to avoid future water issues. Many sensors for the toilets, urinals and sinks do not work. Paint is weathered and very deteriorated, paint job needs to be performed. The project’s purpose is to solve a major problem for the park’s visitors.

There is only one restroom location for visitors at the San Cristobal Outworks. Thousands of visitors’ everyday experience hardships to use the park’s restroom facilities. Seniors, parents with infants, and visitors with disabilities are the most affected by the current situation. If the restrooms are not repaired soon, the situation will continue to affect the public in a negative way.

The San Cristobal Outworks Guardhouse storage room and restrooms will be rehabilitated. This project will include piping repairs, masonry repairs, and electric repairs. This project will remove and replace all the toilets, urinals, mirrors, sinks, fixtures, lighting, partitions, tiles (floor and wall), hand dryers, toilet paper dispensers, paint, and all bathroom accessories will be replaced.

The ceiling will also be cleaned repaired, and repainted. This project will include the installation of new baby changing stations, bathroom counters, product dispensers, and a public drinking water fountain station will be installed exterior to each restroom.

2 OBJECTIVES

This project will totally rehabilitate the restrooms at the San Cristobal Outworks Guardhouse.

The contractor will be responsible for providing assessment, planning, engineering, compliance, and construction of the existing restrooms. The existing restroom infrastructure continually fails and clogs. All the sewage piping and venting are inadequate for the public restroom and must be investigated and replaced.

This project will include completely removing and replacing all mentioned equipment in this SOW. The work shall rehabilitate the historic structure while protecting historic fabric.
