A site investigation, also called geotechnical investigation, is done by taking ground samples for analysis and creating a detailed report of findings and recommendations for the site. It is crucial in helping engineers identify hazards and risks to be mitigated before a construction project begins and determine if a location is ideal for planned development.

Aside from determining suitability for construction, a site investigation helps engineers come up with safe and economical building plans appropriate for the area. It’s also useful in long-term planning because it helps foresee natural or human-made changes and determines corrosivity caused by groundwater conditions.

This article will briefly discuss (1) what hazards to look out for when conducting a site investigation; (2) technology for convenient data gathering at the site; and (3) provide free site investigation templates you can download, customize, and use.

Site investigations aim to identify and address hazards and risks that can impact the project and cause problems for its stakeholders. Here are some common hazards that engineers should look out for during site investigations.

Physical hazards

- Possible soil oversaturation (too much water) or undersaturation (too dry) can cause foundation issues in the future if not discovered and mitigated.

- Engineers should be aware if a site is near an active fault line so that the structure can be built to withstand projected earthquake magnitudes.

- Structural hazards from demolished or nearby old structures should be considered while investigating the site.

- Natural and manmade disasters that may have rendered a site inhabitable should be checked and mentioned on the geotechnical report.

Chemical hazards

- Take samples for lab testing to determine if there are chemical hazards in the soil or underground water due to contamination caused by nearby agricultural, manufacturing, or mining activity, among others.

- Demolished old structures near a site need to be tested for traces of asbestos.

Biological hazards

- Soil and water samples taken from the site will help determine if nearby industries may have caused biological hazards.

- Consider former landfills and waste treatment in the area when checking the site for biological hazards.

Environmental and Social hazards

- Consider the project’s impact to the environment’s flora and fauna. Assess the environmental risk to help avoid future issues.

- Be aware of social risks particularly in high-density urban sites or indigenous territories. Consult the government and local stakeholders on the possible social impact to and by the project.

With the diversity and huge amount of information to capture during site investigations, it is beneficial to take advantage of technology that can help make data capture easier. iAuditor, the world’s most powerful mobile inspection app, can help engineers conveniently record information anytime, even in remote sites.

Top 3 Site Investigation Templates

1. Site Investigation Report Template

A site investigation report template is used by geotechnical and civil engineers to determine the characteristics of the soil in a site intended for building projects. The site investigation report can help gather data for determining current and future risks to be considered before beginning a project. Use this digital template to:

  1. Get authorized person’s signature to access site
  2. Take photos and record soil characteristics
  3. Geotag the exact location
  4. Record overall findings and provide recommendations
  5. Sign off with the site investigator’s digital signature

2. Borehole Log Template

A borehole log template is used by engineers to record every borehole sample taken from the site. The samples are taken into a laboratory for further testing and the detailed results are included in the geotechnical report. This borehole log template allows engineers to:

  1. Create as many logs and sample numbers for every borehole sample taken
  2. Take photos of samples and enter detailed notes
  3. Geotag photos for accurate mapping of where the sample was extracted

3. Geotechnical Report Checklist Template

Geotechnical report checklists help geotechnical and civil engineers ensure that all requirements and information needed for a site investigation report are completed. Geotech checklists also help improve the quality of geotechnical reports and avoid duplicate site investigations. This simplified geotechnical report checklist uses a “Done/In progress/Not Applicable” response set and allows notes to be entered if needed. This iAuditor template can be edited to fit your site investigation report needs.
