- Description
- GENERAL: The National Park Service, Department of Interior, is conducting a sources sought for the work described below. This notification is for market research purposes to identify potential contractors who have the skills, experience, and knowledge required to successfully complete this effort and does not constitute a commitment, implied or otherwise, that a procurement will be accomplished. The amount of interest will determine the possibility of a set-aside or full and open competition. This is not a request for proposal or invitation for bid. NPS would like interested parties to submit related project experience and resumes for key individuals to Rebecca Bizier at Rebecca_Bizier@nps.gov, or via fax to 303-987-6646 by close of business Tuesday, February 10, 2009. PROJECT DESCRIPTION: Work will include analysis of existing conditions, cleaning of existing historic concrete, replacement-in-kind of portions of historic concrete including but not limited to pavements, stairs, curbs, walls, cornices, benches, patching/repair of spalls and delaminations at concrete elements with an exposed aggregate finish, replication or repair of concrete piers and decorative elements (urns, balusters, obelisks, fountain elements, water spouts, handrails, coping and other pre-formed objects and decorative elements), creation of molds from extant or portions of extant features, repair of concrete with imbedded elements, and repair of cracks in historic concrete. This would require replication, creation, and/or analysis of concrete mixes as required. Repair of modern concrete that is incidental to the historic concrete is also included. NAICS 238110 Concrete Repair. Work will potentially occur throughout the National Capital Region. The National Capital Region (Maryland, District of Columbia, Virginia, and West Virginia) contains more than 700 individual sites, ranging from community parks that serve as neighborhood gathering places to national monuments that attract visitors from around the world. Serving more than 40 million visitors annually, the parks of the National Capital Region encompass more than 87,000 acres of parkland and open space with thousands of historic structures and archeological sites, hundreds of miles of trails, bike paths, riverfront, scenic parkways, and historic canals. The National Capital Region also offers visitors numerous statues, presidential memorials, historic forts, Civil War battlefields, and the White House. Despite ongoing repair and maintenance these sites continue to have large amounts of deteriorated exposed aggregate retaining walls, paving, and steps remaining and deterioration of walls and paving continues. The National Park Service (NPS) seeks interest from experts in the concrete industry capable of providing expert advice, formula development services, and ongoing repair of the decorative concrete. In some cases formulas for the concrete mixes for repair have been developed, but the Park has varied concrete within and additional mixes and formulas may need to be developed to match the historic concrete in the color, texture, frequency of specific aggregate colors and size of the historic concrete aggregate and matrix, including, when possible, using materials from the original quarries. There are slight variations in the same mix for the concrete in different locations; therefore, some adjustment must be made to create samples to match specific locations. Work may include submitting alternate design mixtures when characteristics of materials, project conditions, weather, test results or other circumstances warrant adjustments. Work may include replacement of portions of concrete pavements and stairs, patch repair of spalls (missing, damaged or deteriorated locations) and delaminations at concrete elements with an exposed aggregate finish, and replication or repair of concrete piers and decorative elements, providing steel reinforcement where necessary. Spalls are both shallow and deep, deep spalls being those which have exposed rebar within the spalled area and shallow spalls those with no visible reinforcing (prior to cleaning and preparation for repair). Some repairs may require injection grout and/or repair mortar. Repair of modern concrete that is incidental to the historic concrete is also included. EXAMPLE OF WORK: Meridian Hill Park is located in Washington, D.C. approximately one and one-half miles north of the White House. It is one of Washington's most important and historic parks in the tradition of the monumental, federal parks of the Mall. Bounded by 16th Street on the west, Euclid Street on the north, 15th Street on the east and W Street on the south, Meridian Hill Park is located within a diverse and changing neighborhood. Originally envisioned as "a classical villa landscape at the center of a vibrant and interesting residential neighborhood", the park continues to play an important role in the physical as well as social landscape of the neighborhood. Meridian Hill Park was designated a National Historic Landmark in 1994, as "an outstanding accomplishment of early 20th-century Neoclassicist park design in the United States" This significant historic resource was originally created to provide visitors and the citizens of Washington D.C. with a formal garden comparable to the public gardens of Paris, Rome and other foreign capital cities. Among its distinctive architectural features are walks, terraces, pools, fountains, and cascades that were constructed of exposed concrete aggregate, using the pioneering techniques developed by craftsman John Earley TITLE OF PROJECT: Repair and Maintenance of Historic Concrete, National Capital Region Parks, District of Columbia, Maryland, Virginia, and West Virginia TYPE OF PROCUREMENT: NPS is exploring the possibility of soliciting and awarding a multiple year construction IDIQ contract(s) to satisfy this need and is trying to determine the contractor interest, availability, and expertise in this type of requirement. SUBMIT: Please indicate your company's interest in the project by submitting a Company profile with "resume" of your company's experience specific to Historic Aggregate Concrete work. Include references for related experiences. Many of the parks are open to the public daily. The example (Meridian Hill Park) is open to the public daily. Interested contractors are welcome to visit the sites for closer inspection of the work required. Due date to submit interest: Close of Business Tuesday, February 10, 2009
