MEASURED DRAWINGS

At the outset of any preservation, restoration or rehabilitation project, the first question is: "Do we have any measured drawings of the building?" If any drawings are to be found, that question is quickly followed by "How reliable are they?”

High quality measured drawings in CAD format that accurately describe the existing conditions of a building's size and shape can be hard to come by. Drawing on deep experience with both conventional field techniques and newer technologies such as digital photogrammetry and laser measuring devices, Aaslestad Preservation Consulting LLC has made this work its specialty.


Photogrammetry

Photogrammetry is an incredibly powerful tool for capturing and recording the size, shape and condition of an existing structure. By allowing an architect to create an intelligent "point cloud" & a three dimensional wire frame model of an existing building from photographs off site, this technology provides a safe and economical means to measure and draw even the most complicated structures. Mr. Aaslestad is equally at home using time honored conventional techniques of measuring and drawing by hand as well as using laser technology to ensure that his clients get the information that they require.

While the most common application of photogrammetry in architectural work is to measure and draw hard-to-access elevations, this technology also provides an excellent way to prepare plan drawings and building sections. By accurately defining the limits of a building envelope, many of the complexities in creating an accurate interior floor plan are resolved. Other deliverables can include elevations of interior spaces and reflected ceiling plans.

• Elevations (exterior & interior)
• Plans ("envelope plans" as well as interior partition layouts, floor plans)
• Building sections & profiles
• Reflected Ceiling Plans
• Detail Drawings


Hybrid Drawings

Mr. Aaslestad has pioneered the use of combining rectified, scalable photographs with measured line drawings in CAD as a powerful way to capture and represent the current state of architectural surfaces. These “hybrid drawings” combine the quantitative power of vector description with the qualitative richness of a good photograph. See the Ortho-photography tab for more information.
