Before starting a new construction project, you need to do a lot of groundwork.
Site investigation is one of the most critical steps in any construction process, and it’s something that you shouldn’t skip or rush. By taking the time to do a proper site investigation, you can avoid many common problems and save yourself a lot of headaches down the road.
So what goes into a site investigation? This blog post will look at site investigation, what it entails, and why it’s so important in construction.
What Is Site Investigation
Site investigation is the process of gathering information about a proposed construction site. This information can include the soil composition, groundwater levels, and existing structures on the property.
The goal of site investigation is to get commercial environmental consulting experts to give a clear picture of the site conditions so that you can plan your construction project accordingly. Site investigation should happen before developing any plans or designs. You should then revisit it throughout the project as new information becomes available.
Every project has its own set of circumstances, so the site investigation process will vary from project to project.
You should do geotechnical site investigation for each project separately. That way, all the information gathered is accurate and specific to that one construction plan.
The Role of American Society for Testing and Material (ASTM)
The American Society for Testing and Material (ASTM) is a nonprofit organization that develops voluntary consensus standards for materials, products, systems, and services. One of the ASTM’s many standards is Standard Practice for Site Characterization.
This standard guides how to conduct a site investigation. It covers data collection methods, laboratory testing procedures, and report preparation. By following this standard, you can be sure that your site investigation will be thorough and accurate.
Boring, drilling, and testing are the most common ways to collect data during a site investigation.
The Site Investigation Process
So what goes into a site investigation? There are many different steps, but the following is a general overview of the process.
Phase One: Preliminary Site Assessment
This phase includes things like property research, stakeholder interviews, and aerial reconnaissance. During this phase, you’re trying to get an overall picture of the site and identify any potential problems or issues.
Phase Two: Fieldwork
In this phase, you’ll conduct on-site investigations like soil sampling and subsurface exploration. This is where you gather all the data you need for the final report.
Phase Three: Report Preparation
Once all the data has been gathered, you’ll need to compile it into a final report. Site investigation reports are usually made up of maps and charts. They’ll include things like soil composition, groundwater levels, and subsurface characteristics.
Site investigation reports are written in plain language to make them accessible for everyone on the project team.
Importance of Site Investigation in Building Construction
Now that we’ve gone over what site investigation is and what goes into it, let’s look at why it’s so important in construction. Here are just a few reasons.
Helps You Plan for Site Conditions
It’s much easier to draw up a plan when you know the site conditions. Site investigation helps ensure that your construction plans will function once they’re in place.
For example, you may discover high groundwater levels during excavation. Then, it might be necessary to install drainage pipes before moving forward with construction. Without this information beforehand, your building or parking lot could become flooded.
Another example will be if you discover a toxic soil condition. In that case, it would probably make more sense to build on an adjacent property instead of the one you’re working with. That way, your team won’t have to deal with hazardous materials or waste removal.
Site investigation helps avoid these issues by gathering accurate information before construction begins. This ensures that everyone knows what they need to do and how long it will take them beforehand.
Helps You Stay on Budget
If you don’t do a site investigation, you could end up spending more money than necessary. For example, if the soil is too soft for your planned construction, you might have to install pilings or other foundation support systems. This can add a lot of extra cost to your project.
Likewise, if you didn’t budget for proper drainage, you could end up with a wet building that you’ll need to dry out. These are just a few examples of how not doing a site investigation can blow your budget.
Site investigation helps prevent these problems by identifying potential issues ahead of time. That way, you can plan for them and stay your budget.
Prevents Damages to Infrastructure
One of the biggest dangers of construction is damage to existing infrastructure. This can include things like roads, bridges, pipelines, and electrical lines.
It’s much easier to prevent this type of damage than fix it after the fact. That’s why site investigation is so important. By thoroughly investigating the site, you can make sure that your construction crew knows where all the infrastructure is located.
This way, they can avoid hitting pipes with their excavators or dropping heavy objects on power lines. By taking these precautions, you can help keep your project on schedule and minimize damages caused by construction.
Helps You Comply With Regulations
Every construction project needs to comply with a variety of regulations. These can include building codes, environmental laws, and safety standards.
Site investigation is the best way to ensure that your project meets all of these requirements. By gathering accurate data about the site, you can design a plan complying with all the relevant regulations.
This is especially important for complex projects with many different regulations to consider. Having a solid site investigation will help keep your team organized and on track.
Helps You Avoid Lawsuits
Construction projects can often be complex and chaotic. This can lead to mistakes happening on the job site. If someone is injured or property is damaged due to these mistakes, they may sue the construction company.
Site investigation helps prevent this by ensuring that everyone on the project knows what they’re doing. By gathering accurate data about the site and following safety protocols, you can help minimize the chances of an accident.
This also goes for environmental damage. If you improperly dispose of hazardous materials, you could end up facing fines from regulatory agencies. By conducting a proper site investigation, you can avoid these potential problems.
Helps You Understand the Site
Not all construction projects have a lot of prior knowledge about their sites. It’s not uncommon to work on undeveloped land or a property that no one has worked with before.
In these situations, it can be vital for your team to do a site investigation to understand the challenges the project will face. This way, everyone knows what they’ll need ahead of time and can plan accordingly.
If there are any problems identified during an investigation, make sure to keep them in mind as you plan your project timeline and budgeting needs. The more information you gather, the better prepared you’ll be when things don’t go according to plan.
Helps Determine the Construction Materials Needed
One of the most critical aspects of site investigation is determining the type and amount of construction materials needed. By studying the soil conditions, you can figure out:
- What kind of foundation to put in
- What types of retaining walls are needed
- What type of roofing will work best
This information is also essential for budgeting purposes. By knowing how much material you need, you can ensure that you’re not overspending on your project.
It’s also important to consider environmental factors when selecting construction materials. For example, if you’re building a structure near a waterway, you may want to use non-toxic materials that won’t harm the environment.
Helps You Navigate Around Obstacles
As we mentioned earlier, construction projects often involve working in an area with already existing infrastructure. It’s important to know where these obstacles are so that your crew can avoid them.
A proper site investigation will help you map out the entire site and identify potential hazards. This information is essential for safety purposes. By knowing what to expect, you can prevent accidents on the job site.
It’s also helpful to have this information when it comes time to apply for permits. If you know that there are underground pipes or power lines on the property, you can let the relevant agencies know ahead of time. This will help speed up the approval process and keep your project on schedule.
Site Investigation in Construction
Site investigation is an essential part of any construction project. By conducting a proper investigation, you can make sure that your team is organized and prepared for anything that comes their way.
Additionally, site investigation can help you save time and money on your project. Make sure to consult with a professional geotechnical engineer to get the most accurate data possible.
