Façade Architectural Surveys

At G&P Associates, we specialize in conducting comprehensive facade architectural surveys for buildings of all sizes. Our teams use as-built drawings to identify and assess any defects or potential hazards that may be present. Our surveys include a detailed report and recommendations that will assist other architectural teams in properly evaluating your building for a remodel. Trust us for your façade architectural survey needs and ensure the longevity of your investment.

We have produced hundreds of façade surveys for building restoration companies, developers, architects, and engineers. Below shows a NYC façade survey with a colorized point cloud and basic façade drawing (Manhattan, NY).

In New York City, Local Law 11/98 requires buildings over 6 stories must be inspected every 5 years to maintain façade safety. If as-built façade plans do not exist, building restoration engineers may hire a company to laser scan and produce accurate façade surveys and as-built elevation drawings.

The façade as-built drawings may be low detail where basic façade survey elements are shown or highly detailed where every terra-cotta, marble, or brick mortar joint and decoration are accurately displayed. Below shows an as-built façade Revit model (Manhattan, NY) of detailed elements. The model was used by NYC historical restoration engineers to re-produce damaged elements.

Historical landmark drawings of the façade are another reason to document the existing conditions. In New York City and Philadelphia, if the building is over 100 years old, developers are required to produce accurate landmark as-built elevation drawings of the façade. These building façade architectural surveys are then given to the New York City historical society. Below shows a façade survey (Brooklyn, NY) in moderate detail:

Software we use are AutoCAD, Microstation, Revit, and Rhino. Sometimes the project requires only minimal detail of the facade's existing conditions. Other times, the project requires very extensive as-build detail of the facade. The amount of detail required can depend on several variables. We can laser scan your building façade to provide the right amount of detail for your needs.

When extreme detailed facade as-built is required, we sometimes combine photogrammetry from a camera and/or drone rectified to the scans so that every crack and deformation can be seen accurately on the façade survey. Below shows a partial facade survey from Philadelphia, PA.
