Site preparation is an essential part of any construction project. It enables your team to work more efficiently and safely, and ensures that your building is on solid ground.
The basic process includes removing trees, debris, and protruding rock. It also involves grading the land to prepare it for construction.
Site Clearing
Before construction teams can begin their work, they must clear the site of any debris and other issues that may interfere with the build. A poorly cleared site can cause delays and additional costs for the project. Santa Monica roofing contractors particularly value this step for an easy-sailing installation process.
Site clearing is one of the most important stages of site preparation for home construction. It allows construction crews to create a solid foundation and ensures that the construction process is as safe as possible.
A professional site clearance company will know how to handle all types of debris, from brickwork and metal to trees, soil, and other objects. They will also have the necessary equipment to complete the job correctly.
Land clearance is a vital step in any site preparation process, whether you’re building a new home or renovating an old property. This includes removing debris and other unwanted items that can cause damage or even injury to those working on the site.
The team will also make sure that any buried water tanks and underground storage tanks are properly disposed of. This prevents the risk of flooding and other problems during construction.
It’s also important to get rid of any hazardous waste that you might have on the site, such as chemicals or asbestos. These materials are highly toxic and should be handled by a waste carrier with a valid license.
Once your property has been cleared of any debris or hazardous materials, it’s time to start laying the foundations for your new building. This can involve excavating the ground, leveling it, and compacting it so that it’s ready for construction.
If your property is wooded, you’ll probably need to remove some trees as well as stumps. This will give your construction team access to the entire building perimeter and allow them to do their job efficiently.
Trees should be removed about 20 feet around the entire perimeter of your home. This will ensure that the construction crew has enough room to move around safely during construction and that your house can be constructed on a level surface without sinking or drooping.
It’s also important to remove any weeds or vegetation that might be present on the site. This can help to improve the appearance of your home while reducing your energy costs. It can also prevent invasive pests from taking up residence in your yard.
Site Surveying
When building a new house, it is important to know the land boundaries and property lines before construction begins. This will prevent you from getting in legal trouble or causing disputes with your neighbors. Moreover, it will make it easier for you to secure your loan from a banking institution.
If you want to avoid these problems, you must get a professional survey done before you begin construction. A survey will show you the property’s boundaries and will also reveal topographical details, such as slopes and geographical features.
The survey will also reveal all the existing structures on your property, as well as any improvements or additions that have been made to them. This will allow you to plan for future construction projects that will take into account the area’s unique characteristics.
Moreover, a survey will give you the necessary information to comply with local regulations. This is important because many cities and counties have restrictions on what can be built on a certain piece of land. If you do not have the right information, your project could run into compliance issues that can cause a lot of damage and delay your construction.
Before you begin your survey, it is important to choose a reliable site contact who can answer all of your questions about the land and provide you with information about the area. This person can be a friend or an employee of your company. It is best to find a good site contact early on in your construction project so you can develop a relationship with them.
In addition, it is important to note that different people will have different working styles. For example, one person might be more comfortable doing field measurements with a compass or a GPS while another might be a more confident and experienced surveyor who would prefer a theodolite.
It is also helpful to have a site checklist to help you stay organized and on track throughout the surveying process. This will ensure that you always have what you need when you need it and that you don’t forget to do something. It can be used before, during and after the surveying process to make sure you have completed all of your tasks in the right order.
Soil Testing
Soil testing is one of the most important parts of the site preparation process. This test determines the soil’s stability and structural integrity and identifies any problems it might pose during construction.
It also reveals the density, compaction, sand content, and any contaminants that may be present at the site. This information is essential to a structural engineer in designing the foundations, footings, and slabs of the home build.
The results of a soil test help engineers predict how the ground will react to changing weather conditions, and if it will support the structure. For example, if the soil on your site swells in wet conditions and shrinks in dry ones, that could affect the design of the foundations or footings.
A soil test usually involves taking samples of the ground from a designated area on your property and sending them to a local lab for analysis. The lab will run a variety of tests that target specific groups of compounds and minerals to reveal any issues.
Some of the tests that are commonly conducted include moisture and specific gravity, sand content, soluble salt levels, and other aspects of soil composition. Soil testing is an essential part of any building project and should be done as soon as possible to ensure that you receive accurate results and a quality build.
Soil tests are also a requirement of most home building contracts, especially for new builds, because the soil profiles on each block of land vary from place to place. This means that you’ll need to have a full report on the soil before the building contractor begins digging for a foundation.
Depending on the site, the soil test can be performed by a licensed geotechnical engineer. These professionals have a degree in civil engineering, hold a state-issued license and pass the National Council of Examiners of Engineering and Surveying (NCEES) Fundamentals of Engineering exam.
The most common type of soil test is the oven-drying method, which consists of placing a weighed sample in an oven at 110+5 degrees Celsius for 24 hours. After the test is completed, the soil is weighed again and the difference between the two weights is a measure of the moisture content. This method is considered the most reliable and precise.
Grading and Compaction
Before any construction work can take place on a site, it needs to be cleared, graded and compacted. This is a critical step in ensuring the construction process goes smoothly and meets all necessary standards. Without this, the project will be delayed or even canceled.
Grading is the process of removing unwanted or existing land features from a property to create a more functional space. It also makes it easier for people to navigate the area.
It’s important to have proper grading done before any construction begins because it can affect the final building design and the drainage of the site. Improper grading can also cause erosion and other problems, such as settling or sinking of a foundation and the formation of groundwater.
The basic grading plan for a property accounts for the slope of the land, the soil type and drainage requirements. It also takes into account any aesthetic concerns that may arise.
If a site is very steep, it’s often necessary to use retaining walls to prevent erosion. It can also be necessary to bring in more topsoil to fill low-lying areas and smooth the surface of the site.
When a grading plan is drawn, it usually includes contour lines that indicate the slope of the property. The lines are typically set in 2-foot changes in elevation.
Once a grading plan is approved, a crew of professionals will be sent to the site to begin the actual work. They will scrape topsoil from one area and then move it to another, leveling the ground as they go along.
After grading is completed, the contractor will have to get the grading inspected by local governmental agencies. These inspections ensure that the grading process follows the approved grading plans, water quality management plan, building codes and county ordinances.
A grading certification letter must be submitted by the owner or contractor to the grading division before requesting an inspection. This will guarantee that the grading process follows all precise grade requirements for the project to be eligible for Building and Safety Department clearance.
Compaction is an essential part of the grading process because it helps increase the bearing capacity and stiffness of in-situ or chemically modified soils by adding friction and interlocking particles, and decreasing future settlement of the soil. It also helps eliminate voids, which reduces the possibility of shrinking and swelling properties that could compromise the structure of a roadway or pavement.
