“Facts About Site Investigations” describes the many aspects of an investigation and why they are an integral part of all marine construction projects.
A site investigations is the first step toward a successful dredging project. Conversely, an inadequate site investigation is one of the most frequent causes of delay and of additional unexpected, unbudgeted costs. With modern techniques and computer-based site investigations, accurate preparation has become realistic and it will help define the design of the project and will limit, as much as possible, conflicts arising because of unforeseen conditions. For a “ground examination”, data collection of three aspects are recommended: geological and geotechnical evaluations; bathymetric surveys; and environmental assessments. This will answer some basic questions such as:
- What types of soils and material are present?
- Are these materials dredgeable?
- What type of equipment and plant will be needed?
- What will the wear and tear on plant be?
- Is the stipulated budget feasible for the work to be carried out?
- Why do site investigations matter?
- When is a site investigation necessary?
- When should a site investigation take place?
- What constitutes a thorough site investigation?
- What are geotechnical and geological evaluations?
- How is geological data gathered?
- What is a bathymetric survey?
- What are environmental assessments?
- What tools are used for site investigations?
- Are there specific site investigation techniques for rock?
- How many samples should be collected?
- What are other aspects of a site investigation?
- Who is responsible for the site investigation?
- What are the advantages to a site investigation?
- Who benefits from a good site investigation?
