PMSS Project Details


Project ID:FHWA-PROJ-08-0025
Project Name: Use of Laser Scanning Technology to Obtain As-built Records
Status: Active
Last Name:Duwadi
First Name:Sheila R
Office: Office of Infrastructure Research and Development
Team:Hazard Mitigation Team
Roadmap/Focus area(s): Historic Preservation
Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:Today there are several hundred historic covered bridges remaining. Although there is much effort to preserve these structures, oftentimes a high cost of restoration, neglect, and vandalism takes its toll, and many are lost forever. One of the more famous bridges from "The Bridges of Madison County" movie fame was burned down last year. As we cannot completely prevent these types of incidents from occurring, we at least should properly document these bridges for posterity. The National Park Service’s Historic American Engineering Record has efforts underway to document historic structures. Their Level I documentation is defined in the Secretary of the Interior’s Standards and Guidelines for Architectural and Engineering Documentation, and consists of measured and interpretive drawings, large-format photographs, and written historical reports. In order to assist in this effort, newer technologies need to be explored that can provide as-built records at a faster rate and with more accuracy.
Start Date: September 8, 2008
End Date: September 30, 2013
Goals:The objective is to identify and demonstrate laser scanning technology to scan existing bridges for the purpose of obtaining as-built records in resolution that meets the Level I documentation criteria of the Historic American Engineering Record as defined in the Secretary of the Interior’s Standards and Guidelines for Architectural and Engineering Documentation.
Test Methodology: This study will explore laser scanning technology to scan existing bridges. Priority will be given to any bridge in danger of collapse or removal.
Other Information: Funding is $100,000 from the Federal Highway Administration and $30,000 from the Forest Service - Forest Products Laboratory.
Expected Benefits:This project resulted in defining methods to acquire as-built records of historic bridges without hands-on measuring and is applicable to any structure.
Deliverables:Name: Feasibility of Laser Scanning Technology in Obtaining As-built Records and Architectural Drawings.
Product Type(s): Research report, Techbrief
Description: The product is a report on the feasibility of laser scanning technology for obtaining as-built records for covered bridges.
