Preparing the site for a new construction is the first step. This prepares a site for construction and gives a project a head start.
This includes demolition, clearing the site, excavation, grading and drainage. A thorough assessment of the site, including soil, is required. This allows contractors to choose the best foundation. It takes into account factors like frost penetration depth, and potential obstacles to excavation. It also considers the required level of drainage. A geotechnical assessment will be done to determine the best way to prepare the site for installation of a foundation or underground services.
Steps to prepare a building site
It is impossible to start a building construction project without first preparing the site. Construction site preparation is a difficult task that must be done carefully. Site preparation involves several steps. Each step must be carefully implemented to ensure a perfect foundation. These are the steps site preparation contractors must follow:
Site clearing This is the first step in any residential or civil construction project. This involves removing trees, brush, stones, or vegetation. This will also include the demolition of any unwanted items, such as buildings or houses. After demolition is complete, the site will then be cleared of all rubbish and prepared for excavation.
Soil testing: This is the most critical step in site clearing. The soil testing determines the structure of the building. It is essential to understand the soil’s load bearing capacity and water absorption capacity. The construction project can’t move forward without soil testing.
Excavation of a Building Site: To level the ground, an excavation crew will use heavy equipment. To loosen soil and earthrock, they may have to excavate the ground. Depending on the foundation design, tunnels and shafts can then be dug.
Report on geotechnical issues A geotechnical report is used to inform a contractor about the site’s conditions. Based on soil and subsurface test results, it makes recommendations for foundation design. The geotechnical report contains:
Sampling and soil testing
Description of soil properties
Soil strength and slope stability
Capacity to bear soil
Recommendation for building phase
Site Design Plan: After a soil test, the site design plan is created. This plan includes the location of the septic tanks and underground fixtures. This shows underground installations as well as the location of the new building. Site plans are usually updated as construction progresses. Because objects such as a septic system can shift due to shifting underground rock formations, this is why a site plan should be updated regularly.
What are the various types of building-site preparation services?
Experienced site preparation contractors are required for building site preparation. Reliable contractors will have the equipment and crews to provide the following services:
Excavation and Earthwork
After site clearing and excavation, this is what the preparation contractor does. The preparation contractor will manage the removal of large amounts of soil, rock and gravel from different locations. Excavating services can help with this. To make way for roads, highways and residential buildings, bulk earthworks are often completed. It is possible for excavating crews to have to go into the ground. This is to install tunnels and shafts in preparation for strengthening the foundation.
For the first stage of clearing and preparing the site, demolition services are essential. This is important if construction is needed over damaged or old buildings. Site clearing can begin once the buildings and other objects have been demolished. When removing hard rock to build roads and highways, demolition is necessary.

Grading is an important service which forces water from structures. It is not always level on a construction site. It is usually uneven. It is difficult to build because of the water pools on the site. Grading eliminates drainage problems and ensures a solid foundation. Without it, a construction could fail.
Site preparation is not the same as grading services. Grading services begin after the site clearing has been completed and take about one to three weeks before construction can start. The site clearing project ends with the grading. This requires heavy machinery like bulldozers and excavators. Good site preparation companies will provide grading services based on the International building code.
A fencing is required for any construction project. You can use temporary wire mesh, or galvanized panels for light security. This keeps the public out of the construction area. Site preparation services include heavy-duty fencing that is anti-climb and has added strength and durability.
