Excavation requires proper planning even before ground is disturbed, and this is more so when there is an existing building or other utilities around. Having a properly done SOE permit goes a long way in proving that the excavation will be safe. The SOE systems are meant to protect the construction managers, engineers, and other workers on site from injuries as well as ensuring ground stability during construction. Thus, the team should prepare all relevant plans, data, and safety considerations before applying for an SOE permit.
The following are steps to excavation checklist in preparing the SOE permit.
Vibrations from nearby traffic can affect excavation shoring systems. To determine the excavation scope, the team must complete the following steps first.
Determine the location, depth, length, and width of the excavation. Also, determine the use of the excavation, whether for foundation, basement, utility installation, or other new construction.
The team must also determine the following.
Clear and detailed project information helps reviewers better understand the construction process.
In the next step, evaluate the soil conditions at the site. It is important in determining the stability of the excavation. Various types of soil require various forms of support.
Use information from geotechnical investigations and the findings of the site investigation. Consider soil properties, groundwater conditions, soil stratification and ground movements.
Take into account the following indicators for proper monitoring and verification:
These are essential for choosing appropriate shoring systems and supports.
Deep excavation work can cause movement in nearby structures. Therefore, assess adjacent buildings before excavation begins.
In order to do so, the team should identify all adjacent buildings and nearby structures before excavation.
These include:
Furthermore, the team should document the condition of critical structures before excavation work.
Once you have inspected the site, select the correct SOE system. The correct SOE system will keep the soil from being mobile and control the ground movements during excavation operations.
Some common systems include steel sheet piling, soldier piles, lagging, and diaphragm walls.
For example, interlocking steel sheets form a continuous system surrounding the excavation area. The sheet piling system may control the soil movements and even the groundwater in some instances.
The chosen system must be suitable for the soil, depth of the excavation, and groundwater levels.

Next, design the SOE in detail to ensure structural strength during excavation. Standard elements of such a structure are soldier piles, sheeting piles, walers, struts, tiebacks, bracing, anchors, rakers, and internal supports.
Engineers must evaluate the loading, deflection, stability, connection, construction loading, and load of supported structures near excavation. The design must provide sufficient support in all excavation stages.
An SOE system needs to integrate with the sequence of construction activities that are scheduled to be carried out. So, do not consider the excavation plan as an isolated document.
Illustrate how the team will install the support system and how the crew will excavate the soil progressively across stages.
The sequence needs to include:
Clear sequencing with the help of 4D and 5D Construction Simulation Services helps minimize uncertainties in excavation activities.
Prior to digging, locate any existing utilities that may be present. Examples of existing utilities include but are not limited to water pipes, electrical cables, gas pipes, and drainage systems.
The permit application package should clearly indicate where the team located the existing utilities.
The team should also check for other hazards. Examples of hazards include traffic, ground instability, groundwater, equipment movement, and suspended loads.
Apart from the submission of the SOE drawings, there may be other drawings that the approval body requires to complete the application process.
According to the project in question and the submission rules of the particular area, additional drawings may be:
Here, it is essential to confirm the exact submission requirements of the approving authority.
The safety plans should cover conditions that could affect excavation stability. Weather can alter the condition of the ground quickly.
Too much rainfall can raise the level of groundwater and destabilize the soil. Severe weather can also have an effect on the functioning of equipment.
The safety plan should take into account:
Here, regular inspections should continue throughout the construction process.
An SOE permit stands for a Support of Excavation permit. Primarily, SOE permits are required for excavations over 5 to 10 feet. PE-stamped designs are mandatory for SOE permit applications. The SOE permit application submission must go through local municipal online portals.
Before the submission of the documents, you may conduct a thorough review of the documents to verify their completeness and consistency.
SOE permits coordinate with the environmental remediation program to help control contaminated lands. This ensures that all of your activities are complying with local regulations such as OSHA 29 CFR 1926.
The municipal building department oversees the process of submitting the SOE permit applications.
This process requires making sure that the information contained in the permit application is complete and accurate. Also, the team needs to validate whether the SOE is designed in line with the excavation drawings and the construction sequence.
Authorities typically issue permits only after approving the plans and receiving administrative fees.
Approval for permits may necessitate some revision. The reviewers might ask for more computations, drawings, information, etc.
Answer their comments promptly. Revise all the affected documents and not just one particular drawing.
Keep track of all the revisions made. This is so you don’t end up having contradicting information.
Excavation work should not commence just because you submitted a permit application. Ensure the authorities approve the necessary permit.
Also, ensure that approved plans are available at the project location. Workers must follow the approved SOE procedures and construction sequences.
Should the situation on site change, stop the work and reassess the situation. Changes in soil, water, nearby structures, and depth of excavation work could require engineering review or permit update.
An SOE permit application is not only dependent on plans or drawings. It requires proper coordination between many factors such as excavation, soil, structure, safety, etc. An excavation plan can help the team to find any gap in their coordination. Proper SOE planning creates stronger permit submission processes and ensures the safety of workers.
