Pre- and Post-Construction Surveys

Seismic Surveys provides pre- and post-construction survey documentation of surrounding structures and adjacent properties. These data are essential for a contractor’s community relations and tools for minimizing the risk of unwarranted claims. Pre- and post-construction visual observations and documentation with digital imagery provide indisputable evidence of existing conditions and defects before and after a project.

Why are Pre- and Post-Construction Surveys Important?

A pre-construction survey serves to document pre-existing cracks that could become the subject of concern or a claim after construction begins. The survey serves as a baseline for monitoring any potential construction impacts on the structure and to identify potential structural conditions that might make the structure more sensitive to vibration effects.

The pre-construction survey is a good public relations tool for educating neighbors about a project. Vibration or noise the neighbor may perceive as detrimental to their property, in our experience, will cause the owner to inspect their home more closely, causing them to find cracks they believe are new, yet pre-date the construction activities. By detecting issues early on, this service helps companies act to maximize project success, limit liability, and preserve positive relations with surrounding communities.

Upon completion of construction, a post-construction survey documents post-construction conditions and offers a comparative tool to identify and address neighbor concerns should they arise. The post-construction survey allows the customer to “close the door behind them” when the project is complete.

How Do Pre- and Post-Construction Survey Services Work?

Using digital imagery and standardized forms, pre-construction surveys can involve both exterior and interior photographic and written documentation of the various building materials and existing cracks. The locations and dimensions of pre-existing cracks within a structure are documented for future reference. Existing items such as foundation walls, drywall partitions, flooring, sidewalks, etc. are visually surveyed and noted. General details about the structure, such as age, purchase date, history of repairs, etc. are obtained from the building owner during the survey. The general building materials used in the construction of the structure, water supply type, etc. are also documented.

Upon completion of a project, post-construction surveys re-document the conditions that were present pre-construction, and potentially any new conditions that may have developed. We use the same conventions and perspectives capturing our post-construction documentation allowing for an easy to follow and accurate comparison with pre-construction survey documentation.
