What Are the Essential Requirements of the Design of Foundation

At Prime Piling, we're increasingly called upon to provide independent recommendations regarding piling issues. With our experience in geology, ground engineering and Concrete Piling Service construction method, we can offer entry and help from the initial pile choice right through to helping with precise troubles that would stand up on-site and conveying design input to address special floor conditions.

Involving us early in the task also let us goal the floor investigation at the most crucial design questions, potentially saving expenses and decreasing a task’s carbon footprint. Here, we examine a few latest piling demanding situations we’ve been supporting our clients to solve.

Peer-reviewing site investigation reviews

Often, when a customer inherits a ground research document we’ve not organised, we’re asked to peer estimate it.  A contractor will depend on the facts within the file to design the piled foundations in their building, and if it fails to provide an appropriate statistic, then the client and contractor are at hazard. We are asked to check the investigations done so far, the fantastic facts collected, and the translation of that information, identifying any gaps in the checking-out plan that could need further research.

We have recently been working with a contractor to deal with problems on a site near Watford, precisely due to the client inheriting an insufficient website online investigation file. Driven piles have been followed on the statement that piles might reap a set, but, while a set wasn’t being done, concerns about answer abilities and different irregular floor situations had been raised.

These worries were dominated by the project pursuit of files and our data and performing a site visit to review the ranges. Our findings informed the scheme, which backs to driven piling with a larger diameter. The piling work has now been correctly done.

De-risking the ‘grey location’ for structural engineers

On small to medium construction sites, it looks to fall an increasing number of structural engineers suggest pile range. This may be a grey area for structural engineers, leaving them uncovered to risk so that Prime Piling can add the best value to the pile layout and installation philosophy, helping to optimise the foundation layout.

Often, we are referred to as upon to provide an independent view on behalf of the structural engineer.  For example, we had been requested to assist with overview troubles of ground loss and suddenly high concrete volumes in CFA-bearing piles on a domain in south London. Observation of a handful of the piles being built confirmed that over-flighting was the cause of the problem. We laboured in close teamwork with the piling operator to adjust the installation method, and there was no return of the trouble.

Solved! The case of the lacking concrete

Once more, concrete losses had been exacting demanding situations on a site in. With no apparent clarification as to where the concrete was being improper, service drawings were referred close lifted, but the missing concrete needed to be discovered. Further boreholes had been drilled, and we recommended a few easy falling head soakage checks at levels wherein the concrete was observed to indicate whether or not higher permeability zones had been present within the chalk under the site.

Fissures were determined in the harder chalk at depth, and we decided that once a specific head of concrete was placed, it became lost in the cracks. Part of the issue was the usage of pretty high-hunch concrete with 10 mm rounded aggregate. A mild trade to the concrete mix - a and converting to a twenty mm combination sufficient to cope with the hassle, and no similar losses had been experienced.

Addressing some specific concerns

We were requested to offer input to address specific concerns on other sites.  For example, in a place in north London, we noted that concern bars had now not been installed effectively in a handful of piles and helped discover a solution to deal with a loss in uplift potential.  On a site in Bradford, we recommended that the CFA rig instrumentation output be interrogated alongside our site investigation information to help overcome a potential shortfall in pile potential.

Even the most trustworthy construction tasks can stumble upon unexpected challenges at some point of piling. By concerning specialists early in your project, you can be sure you have the records and awareness you require from the outset to update the building and, just something unexpected occurs, a team of specialists reachable to recommend and lessen the chance of safety, programme and price range.
