Preparing for Site Excavation

Site excavation is a line of business that requires a lot of preparation in order to be executed and completed correctly, and more importantly, safely. Forgoing proper procedures in preparing for site excavation can lead to disaster.

The team at SitePro., an insurance program designed for the needs of site improvement contractors in mind, has seen throughout our history of protecting excavation operations that proper preparation is one of the most efficient practices of risk management.

Preparation begins before the company can even think of scoping utilities or bringing equipment to the site; they begin with inspecting the site and considering the following:

Scope of Work
From the natural ground and contours, site preparation may include many different elements.
The scope of the work to be conducted may include the clearing of any trees and plants, plus the cutting or filling to create the desired ground profiles. This may involve stripping the organic topsoil from the site, clearing any debris from previous buildings, leveling the site or just the building pads, removal of contaminated material, filling and compaction of low areas with certification, ready for the construction work to be set out.

Site Access and Working Space
There must be enough room for the machinery to get to the place where the site preparation is required and enough room to operate once there. Important considerations include the width of access, and any height restrictions. Other considerations include the slope of the land and the ease with which any material can be delivered or removed from the site.

Machinery Selection
The most appropriate machinery is selected based on the site plus the type and quantity of the work to be done. Often the machinery changes during the stages of site preparation. Our range of plant and operators is suited to many site preparations and we have contacts with others when needed.

Material Movements
Ideally the material that is already on the site can be moved and re-used within the site.
This saves the cost of either removing any excess or bringing in new material. Disposal of green waste, organic topsoil, debris and rubbish, plus other excess material is often overlooked as part of a site preparation. The transportation and tipping fees can have a substantial impact on the overall cost.

Scoping out the work, inspecting for site access and usable working space, picking the proper machinery for the task at hand, and figuring out before hand what should be done with the material being moved are all preliminary actions that lay the ground work for a safe job. Mitigating risk begins with knowing what kind of work site one’s team is walking onto before the job even starts.
