IV. SAMUEL GOMPERS STATUE AND EDMUND BURKE

The Samuel Gompers Memorial is located at the intersection of 10th Street, L Street, and Massachusetts Avenue, Northwest, Washington, DC. The Gompers Memorial is part of the National Park Service (NPS)- National Capital Area (NCA)- National Mall and Memorial Parks (NAMA) located in Washington, DC in Reservation 069. The Gompers Memorial is a bronze statue listed on the National Register of Historic Places and is in memory of Samuel Gompers, an English-born American cigar maker, labor union leader and a key figure in American labor history. The memorial was dedicated in 1933 by architect Robert Aitken in the Beaux Arts style.

The Edmund Burke Memorial is located at the junction of 11th Street and Massachusetts Avenue, Northwest, Washington, DC. The Edmund Burke statue was dedicated in October 12, 1922. Burke was an Enlightenment era philosopher that was America’s main ally in Great Britain. He defended our call for liberty within the British Parliament and as a sign of esteem for his support, Burke is now honored in the American capital city. The bronze statue of Edmund Burke is a copy of an 1894 statue in Bristol, England. The original was cast by a Welsh sculptor named John Harvard Thomas. The statue is meant to remind us of the old ties between America and Britain as well as the enduring friendship that has evolved between these two great countries.

V. PURPOSE

The intent of this project is to provide cyclic maintenance to the Gompers and Burke statues so that they are maintained and brought to a restored status. There is no known history of past interventions on either of these two memorials and maintenance has been minimal.

The purpose of this project is to provide conservation services to conduct an initial condition assessment, develop a work plan based on found conditions, implement treatment recommendations and provide a treatment report to include narrative and images describing the conditions found, work performed and recommendations for future treatment and maintenance practices.

The principal features of the work include the erection, maintenance and removal of scaffolding required to carry out the work of this project; the conservation of the bronze elements, the conservation of the granite bases, submission of a conservation treatment report, and high level resource documentation including high resolution digital photographs (minimum 300 dpi) in TIFF format, laser scanning, measured drawings, and anufacturery. For the purposes of this contract, all existing building material is considered historic fabric and the following provides additional details on the requirements to carry out this work.

The project is limited to the bronze Gompers statue and granite base and excludes the cast stone aggregate walkway and steps. For the Burke Memorial, the project is limited to the bronze statue of Burke and the granite base. Unlike the Gompers statue, the Burke statue and base are set on on grass, so walkways or stairs are not a consideration.

This project includes the completion of high level resource documentation for the statuary in the memorial parks using a combination of tools, including high resolution digital photography (minimum 300 dpi in TIFF format), measured drawings, photogrammetry and laser scanning.

iv) Perform a condition assessment including digital photographs after scaffolding or access has been erected to document the existing conditions, to ensure all conditions are addressed, and to provide detailed treatment recommendations. Once access is secured, perform a detailed survey of the bronze to determine if there are cracks, material losses, and/or missing elements of the bronze statues. At the time of the Government’s assessment, there were no visible cracks, losses, broken elements, or mechanical failures around attachment points.

2) Bronze Conservation – Gompers Statue and Burke Statue

a) Gompers Statue: The existing condition of the Gompers and Burke statues is that of an unmaintained urban bronze statue with areas where there is no longer wax coating existing. This is typical of a large bronze statue that has been minimally maintained. There do not appear to be any visible cracks, losses, or missing elements from the bronze statues. The assessment was performed from the ground and did not involve the use of a lift to access the bronze in entirety. The following is a list of accepted procedures identified by the Government after its own initial assessment. Substitutions will be accepted if they are submitted to the COR for review and accepted by the Contracting Officer.

b) Tasks and Accepted Procedures: It is the responsibility of the contractor to achieve general and detailed bronze cleaning, chemical patination (if determined necessary upon further inspection of the bronze surfaces), and the application of both hot and cold wax coatings to the bronze statues. The Contractor shall be responsible for any missing elements that are visible during the site visit. If there is a crack that CANNOT be reasonably be addressed then the Contractor shall submit an RFI (to include time and cost impact) to the COR for review and the acceptance/rejection of the Contracting Officer. All cleaning shall be undertaken through the mildest and least abrasive method.

i) Clean all bronze with a non-ionic detergent solution such as Igepal or Orvus WA Paste, or approved equal and hose pressurized water. Remove dirt, organic material, and loose corrosion with the detergent solution and natural bristle brushes.

ii) Water washing: Wash the surface of the bronzes with low to medium jet pressure, 200-800 psi at 4-6 gpm using a 45 degree fan type nozzle for water soluble dirt and chemical compounds. Optimal water pressure should be determined during preparation of cleaning samples. If loose corrosion and existing wax is not removed through low-pressure water washing then high pressure washing between 3000-4000 psi can be used with a 25 degree nozzle and a stand off distance of 8” to 10” between wand and bronze surface. Delicate areas of the bronze should be cleaned at lower pressures, with a 45-degree nozzle and at increased distances.

iii) Assess water intrusion issues for the bronze statue and repair bronze as needed. Undertake brazing repairs and possible epoxy repairs.

iv) Complete spot-patination sample, patination formula shall be deterimined with COR and Technical Experts. Contractor shall apply an appropriate matching chemical patina to visually minimize patina loss and integrate uneven surfaces to blend together as a whole statue. Review historic photographs to determine the artists original intent for the patina coloration.

v) Apply an outdoor grade designed wax to be used on bronze statues to ensure a long lasting coating. Outdoor Sculpture Wax (Museum Services Corporation), or approved equal may be used. Make sure bronze is free from dust and debris. Wash lightly if necessary. Heat surface with propane torches until wax flows. Apply a coat of hot wax wax over the entire surface, ensuring that wax does not become too thick. Allow it to fully cool. Apply a second coat of hot wax. Once cool, apply one coat of cold paste wax; allow it to dry, lightly buff with soft bristle, horsehair type brushes, and lint-free cotton cloths.

3) Masonry Cleaning: Gompers and Burke

a) Requirements: The Contractor shall clean the granite masonry at the Gompers and Burke statue bases. The masonry cleaning includes the statue bases only and not the cast stone plaza and steps at the Gompers statue.

b) Tasks and Accepted Procedures: The Contractor shall clean all the granite masonry at the Gompers and Burke statues. Because various types of soiling and staining are present, NPS anticipates that more than one cleaning method may be required and shall be included as part of th offerors proposal. General cleaning, to be applied overall, and stain specific cleaning, to be applied locally, are both required as part of this SOW. The range of soiling /staining that the Contractor shall include, but not limited to: atmospheric and biological soiling, carbon soiling, sharpie maker in the inscription on the Burke plinth, and oily stains. Note that the Gompers statue base is a polished stone, only products safe to be used on polished stone shall be accepted.

c) Environmental Requirements: The Contractor will not execute any work in this Section when the air and surface temperatures are outside the operating range of 40 degrees F and rising or less than 90 degrees F and falling. Do not work when rain, snow, or temperatures below freezing are expected within 24 hours

d) Masonry Cleaning Requirements: For cleaning of all granite.

i) The cleaning systems and methods employed shall not damage, etch, burn, bleach, scour, abrade, streak or discolor any masonry surface.

ii) Use only those cleaning methods and materials indicated for each type of masonry/soiling/oily staining and location. Cleaning materials and methods must be addressed in the work plan to be reviewed by the COR and approved by the CO.

iii) No wire brushes or scrapers shall be used. For chemical cleaning, use only brushes that are resistant to chemical cleaners.

iv) Perform each cleaning method indicated in a manner that results in uniform coverage of all surfaces, including corners and interstices, and that produces an even effect without streaking or damaging masonry surfaces.

v) Apply cleaning materials in strict compliance with the anufacturer’s written instructions and as specified.

vi) Rinsing shall commence at the bottom of a given wall and proceeed upward, unless specified otherwise. The mechanic shall operate the pressure washer wand in steady, even passes and maintain a consistent distance of 12-18” feet from the fountain, using a 45 degree tip.

vii) Contractor shall flush heated water through the system for at least one minute prior to rinsing, so that no iron deposits from within the boiler are deposited on the memorial.

viii) Brushes shall be nylon or natural bristle without metal ferrules. Scrapers shall be plastic only, use no metal. Picks shall be wood, no metal shall be used.
