Cleaning and Repointing the Original Building
For biddable construction documents we needed elevation drawings showing every mortar joint on the building. Pre-point-cloud laser scanning, we contracted for elevation drawings at this detail using rectified photography. We supplemented the resulting drawings with plans, partial elevations, and details from the historic drawings and our field survey. Our contract documents made every linear foot of joint quantifiable.
Our specification prohibited use of insecticides during the entire project—an unusual requirement to protect the resident bee colony, part of the Museum’s insect zoo. The contractor had to maintain egress and ingress paths for the bees through a window porthole into their hive in the exhibit.
