Pre-construction surveys are visual reviews of structures adjacent to a construction site. They provide a record of baseline conditions prior to the start of construction.
About Pre-Construction Surveys
Pre-construction surveys provide a record of existing conditions before construction starts.
For developers and contractors, pre-construction surveys can assist a defense against unwarranted damage claims.
For property owners, pre-construction surveys provide a record of baseline conditions that can help validate damage claims, if necessary.
Are Surveys Required?
Pre-construction surveys are usually required for construction that involves any of the following activities:
- Excavation and trenching
- Blasting or Demolitions
- Deep dynamic compaction
- Pile driving
- Heavy construction equipment
- Underpinning operations
What Conditions are Documented?
Pre-construction surveys document cracks and other signs of damage that are visible on the interior and exterior surfaces of the structures.
The documentation consists of high-resolution photographs and written or recorded observations. Video and drone photography may be included.
The images and observations are then organized and submitted to the client in digital form.
Reduce Exposure to Damage Claims
We're ready to help.
GEO's monitoring plans are developed in accordance with local building codes. They present instrument options and locations, frequency of readings, and allowable limits.
Vibration monitors (seismographs) help contractors work within allowed vibration limits. Automated alerts and reports satisfy regulatory agencies and improve community relations.
Crack gauges monitor changes in cracks identified in the survey. Building codes may require daily or weekly readings. Automated crack gauges eliminate site visits.
Building codes may require optical monitoring of affected buildings. GEO's AMTS automated optical monitoring works around the clock without the cost of survey crews.
Dust mitigation is required at most construction sites. GEO deploys real-time, automated dust monitors from Aeroqual.
