The Best Time for Starting Piling and Underpinning Projects

Starting piling and underpinning projects at the right time is fundamental for ensuring competence, safety, and cost-effectiveness. Various factors influence the best timing for these construction actions, including weather conditions, site availability, environmental rules, and project-specific considerations. This guide summarises the best times to start Piling in West Midlands and underpinning projects, along with the key factors that should be measured when planning such endeavours.

Features Considerations for Timing of Piling and Underpinning Projects:

Weather Conditions:

Dry Season:

Ideally, piling and underpinning projects should be started during dry weather conditions. Excessive rain can cause waterlogged soil, making the ground unstable and difficult to work with. Dry conditions ensure better soil stability and easier handling of equipment.


Moderate temperatures are preferable. Extreme cold can freeze the ground, making excavation difficult and increasing the risk of equipment malfunction. Conversely, extreme heat can pose health risks to workers and affect the curing time of concrete.

Soil Conditions:

Soil Moisture:

The moisture content of the soil significantly affects piling and underpinning. Dry or moderately moist soil provides a stable base for these operations, while saturated soil can make driving piles or achieving effective underpinning difficult.

Soil Type:

Understanding the soil type through geotechnical surveys helps determine the best time for construction. Some soil types are more manageable during specific seasons, influencing the timing of the project.

Site Accessibility:

Site Preparation:

Ensure that the site is cleared, and access roads are constructed before starting the project. This includes removing any existing structures, vegetation, and debris that could hinder the movement of machinery and materials.

Traffic and Congestion:

Consider local traffic patterns and avoid starting projects during peak traffic times or events that could cause congestion. This certifies flatter transportation of materials and gear to the site.

Environmental Regulations:

Permits and Approvals:

Securing necessary permits and approvals from local authorities can impact the start date. Ensure all regulatory requirements are met well in advance to avoid delays.

Environmental Impact:

Consider the environmental impact of your project. Some locations have restrictions during certain times of the year to protect wildlife or comply with environmental regulations.

Project-Specific Considerations:

Project Timeline:

Coordinate with other phases of the construction project. Starting piling and underpinning at the right time ensures that subsequent stages can proceed without delays.

Resource Availability:

Ensure that the required resources, including skilled labour, machinery, and materials, are available before commencing the project. Shortages can cause significant delays and increase costs.

Best Times for Starting Piling Projects:



Spring is generally a good time for starting piling projects. The weather is typically mild, and the soil begins to thaw and dry out after winter. This makes it easier to handle the ground and use heavy machinery.


Ensure that spring rains do not lead to overly wet conditions that could affect soil stability.



Summer offers extended daylight hours, allowing for longer workdays and faster project completion. The ground is usually dry and stable, facilitating easier piling operations.


Be aware of heat waves, which can cause health hazards to labourers and affect concrete solidifying times. Appropriate hydration and planning work during cooler divisions of the day can alleviate these hazards.

Early Autumn:


Early autumn provides favourable weather conditions similar to summer but with cooler temperatures. This is a suitable time to start piling projects as the ground remains dry and stable.


Plan to complete major groundwork before late autumn rains begin, which can complicate piling activities.

Best Times for Starting Underpinning Projects:

Late Spring to Early Summer:


Starting underpinning projects in late spring or early summer ensures that the ground is dry and temperatures are moderate. These conditions are ideal for excavation and concrete work involved in underpinning.


Avoid starting too early in spring when the ground might still be wet from winter thaw.




Early autumn is another good period for underpinning projects. The weather is stable, and the ground remains dry from the summer months.


Ensure the project is well underway before late autumn rains and colder temperatures set in, which can affect excavation and concrete curing.

Additional Considerations

Planning and Preparation:

Conduct thorough site investigations and geotechnical surveys to understand soil conditions and potential challenges. Develop a detailed project plan for Underpinning in Surrey, including timelines, resource allocation, and contingency plans for weather-related disruptions.

Health and Safety:

Implement robust health and safety protocols to protect workers from weather extremes and site-specific hazards. Schedule regular breaks and provide adequate hydration and protection for workers, especially during extreme weather conditions.

Communication and Coordination:

To ensure smooth project execution, maintain clear communication with all investors, including contractors, suppliers, and local authorities. Coordinate with other construction activities to avoid conflicts and delays.
