- WORK ORDER SCOPE 3D Laser Scanning Pilot Project 1.0 IDENTIFICATION 1.1 Work Order Name. Conduct Exterior 3D Laser Scanning Survey for Three Federal Facilities in Brooklyn, Atlanta, and Miami. 2.0 OBJECTIVES 2.1 The objective of this work is to generate high-quality documentation using three-dimensional (3D) laser scanning and/or other surveying technologies on three government facilities in Miami, Florida; Atlanta, Georgia; and Brooklyn, New York. These are national pilot projects for the U.S. General Services Administration (GSA) that will use 3D laser scanning technologies for archiving historic building elements, documenting current conditions for existing buildings for planned modernizations, and documenting as-built conditions for new construction. The design objective for this task is to ascertain the viability of usable output data to create 2D-CAD elevation drawings and/or 3D building information models (BIM), as applicable. The program objective is to extend the GSA BIM Guide with a chapter and appendix containing laser scanning generic scopes of work and best practices. 2.2 The following three facilities were selected by GSA Public Buildings Service (PBS) Office of the Chief Architect (OCA) for these pilot projects: U.S. Post Office and Courthouse in Brooklyn, New York; Peachtree Summit Federal Building in Atlanta, Georgia; and the Miami Judicial Campus in Miami, Florida. Each facility has unique objectives listed below. 2.2.1. U.S. Post Office and Courthouse. Planning is underway for a replacement of nearly all the deteriorated terra cotta cladding on the facades of the 1933 section of the structure with new terra cotta or alternate materials, restoration of all existing granite cladding on both buildings, and replacement of the entire slate mansard roofing system on both structures. The building is on the National Register of Historic Places and designated as a New York City Landmark. 3D laser scanning will provide a current-condition record of the existing masonry architecture and assist in future renovation designs and terra cotta fabrication. The objective of the scanning at this location is to provide 2D-CAD elevations required to document as-built conditions. These elevations will assist architecture and engineering firms in developing their restoration and renovation designs. 2.2.2. Peachtree Summit Federal Building. The programming of a rolling renovation of the facility is underway. The building does not have 2D CAD drawings as it was constructed before CAD was developed. The primary objective of 3D Laser Scanning is to provide accurate 2D elevations for the exterior of the facility. There are also significant deficiencies in the original construction that require documentation in order to provide future architecture and engineering firms a representative as-built condition of the facility. The existing aluminum window frames and glazing are out of specification and often require replacement. Concrete columns, beams, and balconies in the open corner sections were constructed out of specification and are starting to spall. 3D laser scanning will allow a more accurate analysis of original construction deficiencies and provide designers with as-built drawings to develop force protection measures and new window assemblies. 2.2.3. Miami Federal Campus. The primary purpose of 3D scanning for this area is to provide an integrated facility plan to map and link the five buildings in the Miami Justice Complex and overhead bridges into a cohesive BIM site model. The initial area that requires scanning is the street-level corridor between the federal buildings on NE 4th Street between NE 1st Avenue and NW 1st Avenue. In addition, the Dyer Federal building on the SE corner of the campus is preparing for a major renovation and restoration and requires historical documentation before the design and construction phases. 3.0 BACKGROUND 3.1 Since 2003, GSA Public Buildings Service Office of the Chief Architect has established the National 3D-4D-BIM Program (http://www.gsa.gov/bim). One primary application area of this program includes the use of 3D laser scanning technology to augment and streamline the management of as-built spatial information. GSA plans to use the data collected from the pilot projects in this Scope of Work to draft a common guide for all future GSA scanning projects. GSA chose three facilities that represent examples from its historic, mid-century, and urban project types. Each facility?s dimensions and pictures are included in Appendix A through C. 3.1.1. The U.S. Post Office and Courthouse is a historic structure located in the Civic Center of the Borough of Brooklyn, New York. It is listed on the National Register of Historic Places and is a New York City Landmark. The building occupies an entire city block, fronting on Cadman Plaza, a major public space around which many federal state and municipal buildings are organized. Originally constructed as a Post Office and Courthouse in 1892, the building was enlarged in 1933. The exterior facades of the 1892 building are built of granite-faced masonry, embellished with carved ornament, dormers and turrets. In designing the addition, great effort was made to emulate the appearance of the 1892 structure. While many architectural details are shared by both structures, the 1933 structure incorporated the use of terra cotta cladding, in lieu of granite, above the first floor. Above this level, the use of granite was limited to the stonework surrounding the second floor windows. An upcoming GSA project will involve the replacement of nearly all the deteriorated terra cotta cladding on the facades of the 1933 structure with new terra cotta or alternate materials, restoration of all existing granite cladding on both buildings, and replacement of the entire slate mansard roofing system on both structures. 3.1.2. The Peachtree Summit Federal Building was constructed over thirty-two years ago and does not have accurate CAD drawings. Many exterior windows have suffered damage from stresses related to existing concrete beam deformations, poor assembly installation, and live loads from wind. Leakage from rain also exists between the exterior concrete beams and window assemblies as a result of poor design and construction. The entire facility will receive a complete renovation and upgrade in future years and will be required to meet updated force protection standards. 3.1.3. The Miami Federal Campus consists of five court, detention, and administrative buildings that are in various life-cycle stages. The Wilkie D. Ferguson, Jr. Courthouse is near completion and includes a tunnel to the adjacent Tower Building. Four other existing buildings are located in the campus with the new courthouse and are connected via tunnels and overhead walkways. The Tower Building connects by bridges to both the Dyer Building and the Federal Detention Center, as well as by tunnel to the new courthouse. The Bureau of Prisons Federal Detention Center connects by bridge to both the Tower Building and the James Lawrence King Federal Justice Building. The David W. Dyer Federal Building and Courthouse connects by bridge to the Tower Building. 4.0 REQUIREMENTS The government anticipates multiple awards as a result of this solicitation. The contractor shall develop and submit a proposal for one, two, or all three locations (each project has a different set of base and optional requirements, see Sections 6 and 7). GSA may make single or multiple awards. 4.1 Final Scanning Plan. The contractor shall refine and submit a final scanning plan.
