Pile driving is an integral part of building foundations because it provides a stable foundation for construction.
Piles support the load of the structure by transferring its weight to a predetermined depth in deep foundations. The piles can either be made of steel, concrete, or wood. The use of piles enables structures to be erected in locations otherwise unsuitable for such construction.
Deep foundations are constructed by driving piles into the ground to hold the vertical elements in place. Large structures, like skyscrapers, are often constructed utilizing this method since it is cost-efficient.
Though the technology is ancient, modern pile driving equipment has significantly enhanced its efficiency.
This article will discuss the established features of pile driving equipment you should look for when determining how well your foundation will be built.
Features to Consider Before Bidding on a Pile Driving Job
Here are a few important features to take into consideration before bidding on a pile driving job and purchasing or renting pile driving equipment, like CZM piling driving rigs:
- Types and Loads of SuperstructuresTypes and degrees of foundation testing, pile testing, settlement and seepage analyses, and analytical models of the pile and structure will depend on the importance of the design and economic considerations.Having a foundation testing program that defines all the relevant parameters, such as ground profiles, soil types, soil strengths, etc., is vital when designing pile foundations for critical structures.
- The Characteristics of the SoilThe piles and pile driving equipment needed for sandy, clay-based, and rocky soils may differ. It is important to analyze the soil and choose the correct equipment thoroughly.
- A Depth at Which Soil Can Support PilesBuildings cannot be erected on top of weak soil, so the weight must be transferred to new-build foundations that can also benefit from piling—the layer of stronger soil below the weak soil.In most cases, pile foundations are associated with strengthening an existing building’s foundation through underpinning, but that is not their sole purpose. Frequently the soil beneath the structure plays a major role.
- Variations in Length of Pile RequiredPile foundations are often needed in situations where the soil quality is poor or in soil saturated with water. There’s a good chance that the foundations will give way, which will, in turn, result in the structure sinking further.The answer might lie in piling if these conditions persist deeper than 2m. A strong foundation is created by taking the weight down through weak soil and distributing it to a firm foundation below, allowing the building to stand securely.
- Materials AvailablePile foundations require a variety of materials, which include steel, cement, plastic, and wood. Furthermore, it is also necessary to embed a structural member into the ground beneath the base of the structure to facilitate the transfer of loads from the core.At this point, the materials available determine how well your project will perform, which means having all materials ready to get started is a must.
- Durability and QualityDepending on the manufacturer and their building methods, the costs of these pile drivers can vary. The buyer should dig deep to learn where the equipment is manufactured and what types of parts are used. It is always best to use a manufacturer that is based in the USA for this type of equipment.
- Available Equipment for Pile DrivingFor driven pile construction, the following types of equipment are required:
- Pile hammers
- Pile caps or helmets
- Piling leads (swinging or fixed)
- Winches and other accessories
Choosing a machine that meets your needs is important for every construction type.
- BudgetAnother important matter to consider is your construction equipment budget.You should do your best to stay under your desired budget while making sure that you acquire the proper equipment. If you save money renting or buying a piece of equipment that is not correct for your job, you will end up spending extra money to replace that piece of equipment down the road. Make sure that you shop around to get the best deal on a piece of equipment that is the proper size for your job.
- Underground Water Levels and Flow IntensityA soil’s bearing capacity is affected significantly by the location of groundwater. A foundation that is not as wide as the depth of water will have less bearing capacity.Foundations and water tables are affected by local soil conditions. The water table may not be a problem if the soil drains well and is relatively dry. However, the ground may swell and become saturated if the soil around a foundation is dense and absorbent. This can exert a great deal of pressure on the foundation walls.
The ‘hydrostatic pressure’ phenomenon occurs in regions where the groundwater table is elevated near the surface of the foundation. In time, water may penetrate solid concrete and leak through the foundation. It is unlikely, but it is possible that excessive hydrostatic pressure would lift some parts of the foundation out of the ground. However, it could cause foundation walls and other structures, such as fences and decks, to shift.
- The Types of Structures in the VicinityIf you’re thinking about starting your project, keep in mind the type of structures in the surrounding area.It would be extremely risky to begin driving pile close to nearby foundations due to the vibration caused by the equipment. Another factor to consider is the noise disturbance created around sensitive areas like a neighborhood, hospital, or school. Based on this factor, you can choose what type of machine to use.
Wrapping Up the Various Components to Consider Before Bidding a Pile Driving Job
While the features of the equipment covered above are all important, the pile driving equipment used often varies based on soil consistency and the pile depth required. This means the equipment used can differ from region to region, and from project to project.
