What is Site Preparation in Construction

The first step before any construction process is to prepare the site you’ll work on. This “preparation” task involves many steps like site surveying, site clearing, grading, leveling, etc.

Following each of these processes correctly ensures the entire site is prepared according to local guidelines and industry regulations, meaning it’s ready to be worked on.

Of course, the work may vary depending on the construction team tackling the project. Most of the time, however, you can expect similar steps when preparing a job site.

What is site preparation in construction? Let’s find out!

What’s Considered Construction Site Preparation?

Site preparation involves all the prep work needed before performing building construction on a site. It involves several crucial steps that must be done before construction workers can begin the main project.

The success of a site preparation project will ensure that any construction activity done there goes down smoothly. On the contrary, the construction crew will experience many problems if they’re dealing with a poorly prepared site.

One of the most important aspects of preparing a site for construction is that it allows engineers to start working without any obstacles. If you were to start a building project on a site that used to be a retail store, for example, you would need to remove everything before erecting the new building.

Preparing construction sites may look like an overwhelming process, but it’s not that hard as long as you have the right team working on your behalf. Below, we’ll cover all the steps needed to prepare a project site correctly.

How Does the Construction Site Preparation Process Work?

All of the following steps must be done before construction begins. The key to success is to get a professional team, use high-quality tools, and be patient.

Doing the right job will ensure the rest of the construction process is easier for everyone, which means you get to enjoy your new building sooner.

Let’s get started!

Evaluate the Site

In this first step, the team will perform a geotechnical site investigation to identify the soil’s stability, check the map’s underground infrastructures, and any other factors that could affect the project.

Evaluating a site goes beyond walking around and removing obstacles. It’s a thorough process that ensures there’s nothing that could affect the new building.

Survey the Area and Test the Soil

All teams must work with a surveyor, who is responsible for denoting boundary lines. This process ensures everyone knows where the construction can go.

In other words, surveying the area helps you determine where you’ll build certain structures safely and how to avoid problems.

We briefly mentioned the geotechnical site investigation, but what does it mean for the soil? In simple terms, this testing process determines if the soil can safely handle the weight of structures and foundations. It’s also important to see if the land can support the heavy equipment that will go on it later.

Another factor about testing is that it tells the team which type of soil they’re working with. According to the USCS, which is used for engineering processes, works with three types of soils:

• Fine-grained soils – Clays and silts
• Coarse-grained soils – Grains and sands
• Organic soils

We also have OSHA’s classification for soil testing, which offers more information:

• Stable Rock: It’s the hardest to work on, but it provides a solid foundation.
• Type A: It fails at a compression greater than 1.5 tons per square foot.
• Type B: It fails at a compression between 0.5 and 1.5 tons per square foot.
• Type C: It fails at a compression of 0.5 tons per square foot or less.
• Multi-Layer Soil: It involves layered soils.

Create the Construction Site Design

When the team is finished surveying and soil testing, it’s time to create a plan!

The plan will include the designer’s vision for the project, which will lay out where all structures will go. This plan also includes where septic and drainage systems will go.

Clear the Site

Here, the construction crew will remove all debris and obstacles around. It will also take care of existing structures, depending on what they’re needed for. The entire process gets done through the use of heavy machinery.

These heavy machines will need easy access to the site, which is why it’s also important to create access points before clearing the site.

Site clearing may also involve demolitions, depending on the case.

Install Erosion and Drainage System Controls

It’s crucial to install the correct systems and drainage controls before starting the construction project. These include silt fences and retention ponds, and they allow the crew to control water runoff. This, in turn, ensures the land doesn’t get affected heavily.

Grade/Compact the Site

The final step is to grade and compact the project site. In other words, the workers will raise the soil to the required elevation and ensure everything is on the same level. Grading is crucial to do before the excavation process.

What Are the Benefits of a Carefully Planned Construction Project?

Here are three main benefits you’ll get from planning your construction site preparation correctly:

Accident Prevention

Occupational hazards aren’t uncommon in these kinds of projects, especially those involving heavy machinery.

By preparing your construction site correctly, you ensure everyone is working up to a high safety standard. This helps prevent accidents.

Theft Prevention

Many construction sites are seen as optimal grounds for theft since the heavy equipment is often left on-site after a session.

Creating a great prep plan ensures you can identify potential security issues before it’s too late, lowering the risk of getting everything stolen overnight.

Compliance

It’s crucial to get the right permits before doing any construction work. Otherwise, you would deal with legal issues later.

By working with professionals in the construction industry, you won’t have to worry about compliance, as the crew is already familiar with what needs to be done to avoid problems.

Construction Site Preparation Checklist | Safety Guidelines You Should Consider

There’s a quick checklist you should keep in mind if you want your construction site preparation to go smoothly. Here’s an overview:

• Identify potential hazards.
• Create a plan to reduce exposure to said hazards.
• Get the contact information of all members of the team.
• Ensure everyone is wearing personal protective equipment on site.
• Secure the site correctly with proper lighting, fencing, signs, and more.
• Manage termite risk if needed.

How Long Can These Construction Projects Take?

It depends on the amount of site prep needed. Usually, residential projects will involve a one/two-month site preparation project.

Commercial projects, on the other hand, could take longer because of their scale. You can expect to deal with different zoning and permitting processes, longer tasks, and more.

The best way to know for sure is to talk to an expert to get an idea.

How Much Does Site Preparation Cost?

It depends on the scale of the project. Here’s a rundown of the average cost per task:

• Surveying – $200-$2,800.
• Clearing – $200-$2,000.
• Soil Testing – $700-$1,800.
• Plan Design – $750-2,500.
• Grading – $800-$20,000.

Keep in mind this doesn’t include utility costs and other extra fees the construction company may charge.

Bottom Line

Not only does understanding how site preparation works help you ensure the safety and success of your project, but it also gives you a better idea of which options you have available for the new structures.

These processes must be handled by professionals so that your new construction lasts for years. If you’re looking for the right experts for the job, consider the team at Ace Construction Texas.
