Proposal for
Phase II –
HABS Documentation
of the Statue of
Liberty
by
Texas Tech University College of Architecture
Date: June, 29, 2001
Submitted to: HABS/HAER, Washington D.C.
A Three-Dimensional Documentation
The College of Architecture at Texas Tech University in cooperation with Historic American Buildings Survey (HABS) and the National Park Service is documenting the Statue of Liberty for the purpose of historic documentation, maintenance and operation of the Statue.
The use of 3D digital scanner technology can be used for the historical documentation of historically significant structure of non-uniform geometry and monumental scale.
Purpose of Work: To collect scan data of the Statue of Liberty from the fort level of Liberty Island.
Location: Liberty Island, New York.
Scope of Work:
Site Visit Planning & Preparation.
Scheduling and Planning
Gathering existing Site Data
Establishing Surveying and Scanning Plan
Planning Documentation
Logistics
Field Data Collection. (July 30 to August 6)
Set registration Targets.
Survey registration Targets.
Scan of the 60% of Statue as defined in the Surveying and Scanning Plan.
Photographic documentation of process and statue.
Field Measurement and documentation as needed.
On-site Field Data Conversion, Modeling, & Testing of Scan Data. The scan team will do some on-site registration, segmentation, and modeling of data clouds to test quality and quantity of on-site data collection.
Project Management: Daily supervision of research assistants, communications with funding agency, and coordination of work effort.
Meetings: Teleconference Meetings as needed with HABS and Park Service.
Reporting: Monthly report. Milestone Report.
Purpose of Work: To convert the scan data of the statue into three-dimensional models, two-dimensional images, and line drawings as needed to generate the finished HABS drawings.
Location: Architecture Research Center, Project Field Office, Texas Tech University, Lubbock, Texas.
Scope of Work:
Scan Data Preparation. The “point clouds” will be registered together to create a single “point cloud” data set. This data set will be segmented into manageable data chunks to be converted into three-dimensional models. (100% of Statue data collected)
3D Modeling. Conversions of scan data into polymesh and nurbs models. (100% of Statue modeled)
Image Capturing. Two-dimensional images will be captured from the
three-dimensional model to facilitate the generation of finished HABS drawings.
Line Drawings. Section and elevation line drawings will be extracted from the three-dimensional models. These drawings will be created as AutoCAD native format drawings to be used as based drawings for finished HABS drawings
Project Management: Daily supervision of research assistants, communications with funding agency, and coordination of work effort.
Meetings: Teleconference Meetings as needed with HABS and Park Service.
Reporting: Monthly reports. Milestone Report.
Purpose of Work: To convert the digital images and architectural CAD drawings produced in the previous tasks into finished HABS standards drawings by Texas Tech University College of Architecture.
Location: Architecture Research Center, Project Field Office, Texas Tech University, Lubbock, Texas.
Scope of Work:
Preliminary Base Drawing Files and Sheet Mockups of Statue. The preliminary CAD drawings in native AutoCAD format listed below will be produced from the Statue model. Washington HABS/HAER office will determine the sheet mockups from the drawing files below.
Note: The drawings below will depict the Statue to a high level of accuracy except in those areas that the scanner is unable to record. Without interior information, the sections will document only the perimeter of Statue. The elevations and axonometric drawings will only include those areas of the Statue that could be scanned. Deep folds of the gown, the tops of the feet and head, and other areas, which could not be seen from the scanner locations, will not be included in these drawings. HABS/HAER may choose to supplement these drawings with other techniques, such as photogrammetry or additional scan data as funding permits.
1. Horizontal Sections. Sections will be cut at 12” inch increments through three-dimensional model of the Statue, producing approximately 110 horizontal sections. These sections will be created as AutoCAD drawing files and provided to HABS/HAER in a digital format.
2. Elevations. Eight (8) elevations at 45 degree increments around the statue, including all cardinal elevations. These elevations will be created as AutoCAD drawing files and provided to HABS/HAER in a digital format.
3. Axonometric. Two (2) axonometric views as selected by HABS/HAER. These elevations will be created as AutoCAD drawing files and provided to HABS/HAER in a digital format.
HABS/HAER will select views, format and level of detail of the above CAD drawings.
Midpoint Review. A HABS/HAER representative(s) will visit the project field office at Texas Tech University in Lubbock, Texas for a midpoint project review.
Finished Sheets. A sample set of finished sheets that meet HABS standards will be done by Texas Tech University College of Architecture.
Finished drawings to be plotted or drawn on archival mylar with archival ink to HABS standards.
The specific views, scale of final plots, and sheet layouts of the finished drawings listed below are to be determined in coordination with DC office of HABS/HAER.
1. Horizontal Sections. Approximately fifteen (15) sections through the Statue.
2. Elevations. Two (2) rendered elevations.
3. Axonometric. One (1) rendered axonometric view
Final Review and Changes. HABS/HAER will provide final review of sheets and changes will be done appropriate to the scope of work.
Project Management: Daily supervision of research assistants, communications with funding agency, and coordination of work effort.
Meetings: Midpoint Project Review. Teleconference Meetings as needed with HABS and Park Service.
Reporting: Monthly reports. Milestone Report.
Summaries of Procedures. This section will contain the procedures and process used to obtain finished HABS drawings from laser scanning technology.
Archival Drawing and Data Files. This section will contain all of the preliminary drawing and data in the appropriate file format and archived to a CD.
Photos and Field Notes. All photos and field notes will be annotated and placed in an appendix in the Final Report.
· Finished drawing sheets on archival mylar with archival ink to HABS and Library of Congress standards.
· Digital files of the preliminary drawings in native AutoCAD format on a Windows formatted CD.
· All point clouds in a ASCII, XYZ format to meet survey data standards on a Windows formatted CD.
· Polymesh and NURB models in IGES format on a Windows formatted CD.
· A Final Report that will contain summaries of procedures, archival drawing files, archival sheets, photos, and other field notes.
