Deep Foundations

A deep foundation is a type of foundation that transfers the structural loads to the deeper bearing strata (end bearing pile) or distributes the loads along the pile shaft (friction piles). In reality, both mechanisms (end bearing and frictional mechanism) contribute to the resistance capacity of pile foundations.

A foundation is considered a deep foundation when the depth of the bottom of the foundation (D) is more than 2.5 times (sometimes conservatively taken as minimum 4 times) the width  of the bearing cross-section of the foundation (diameter of the pile, "d", or the width of the deep footing, "B"). 

Some reasons when Alpha Adroit would recommend a deep foundation over shallow foundation include when the design loads are very high, bearing soils at shallow depth are weak (such as existence of uncontrolled fill), there are site constraints such as property line restrictions, underpinning is required, there are environmental conditions that make construction of shallow foundations difficult or costly, slope stabilization using piles are needed, buried lateral soil retention using piles are required, or other specialized applications require using pile foundations.

Alpha Adroit's Pile Design and Inspection Services

Alpha Adroit's services for deep foundations include pile design, design review, and pile inspection services for cast-in-place concrete piles, driven piles (steel pipe piles, H- Piles, concrete pre-cast piles, timber piles) using hammer and vibratory pile drivers, CFA (Continuous Flight Auger) piles, belled piles, fluted piles, helical piles (screw piles), Compacto piles, pressure injected footings or piles (Franki Piles) , heavy-duty caissons, micro piles, soldier piles (soldier piles and timber lagging), adfreeze piles, secant piled walls, tangent piled walls, buried slurry walls, sheet piles, under-reamed piles, pile groups, and pile caps.

Alpha Adroit Engineering Ltd provides construction Quality Assurance (QA) and Quality Control (QC) services to ensure the construction procedures and materials used for pile foundations conform to the design specifications and assumptions, as well as, to the proper construction practices. The QA/QC procedures will also examine the soil and rock conditions at the site at each pile location to ensure the design bearing capacity is achieved and available to carry structural and other loads.

Alpha Adroit Engineering Ltd accepts all sizes of projects, and no job is too small or too big for Alpha Adroit. Alpha Adroit is generally retained to provide pile inspection services to project owners, prime consultants, piling contractors, general contractors and other sub-consultant or sub-contractors involved with piling construction.
