    Anyone who has tried to add negative skin friction to pile load and then increase the pile length to try to get enough capacity below the zone of negative skin friction should have a realization that that approach is flawed. Neutral plane and the unified design described by Bengt makes a lot more sense.

    Thanks, Tim and Kyle for your insights about load testing and the limitation of the instruments and interpretive models. Even with load test data, there is still a need for reductions of the foundation capacity in design to account for limitations, variability, and uncertainties in the soil profile, the constructed foundation, and the test data.

    I'm not sure what the point of this debate really is. Does Paul suggest that because PDA is not exact, or does not give you a precise stress strain curve, that PDA should not be used for capacity estimates? The reality is that performing PDA on each substructure is way more practical than performing a static load test at each substructure. Also, as Greg mentioned, the static load test is one data point. PDA allows you to adjust pile depth with varying conditions across the bent. The question is how many piles have failed because of erroneous PDA results performed by a qualified operator? is this even a problem? Is this is all about spending more time and money on static load tests to get the "right" answer? if your pile is at refusal on bedrock or stiff clay, how does knowing the actual, fully mobilized resistance save you on pile length? Last point, if the owner contracts out the PDA testing rather than the Contractor, and they require a PE license from the PDA operator, it is not awarded at low bid, but rather on qualifications. Having the owner pay for the PDA testing removes the conflict of interest that may result in questionable testing results.

    In long frictional H pile example, during Dynamic event, the block of soil has an Inertia Force of F=ma (m = weight of soil block, a is acceleration of pile), thus soils tend to be "cored" (i.e., unplugged) during Dynamic event. However, during Static event, a=0, and soil can be plugged/partially plugged/unplugged. For short H piles, they usually unplugged in both scenarios - but CASE method is typically not applicable (JC is typically a lot more outside of 0.4-0.9 range)

    As a former geotechnical engineer working in the foundation specialty field I think this is a high liability issue that nobody wants to touch. In our pricing proposals we exclude competent working platforms. If that is the GC’s responsibility who else do they have to turn to but the Geotechnical engineer of record, who will likely design something overkill that could strain the project financially at that point. On the other hand, I see the subcontractor’s engineer doing the same thing if responsibility lies in their court. No easy answers on this but I like the gentleman’s idea of standardizing the design process so that is addressed early in the project development.

    I shareseveral of the comments expressed by the interviewed colleagus. I belive there are work (design and or construction) aspects that require a courier service, others an e-mailand others still, texting. However, ALL require an exchange between what one party needs form the other and, therefore, a strong line of communication; and being people, we need to establish a personal professional relationship. At a minimum, we need to put a face to a name. This is the only way to ensure open frankcommunication and develop reciprocal TRUST. Our work is NOT just technical, but personal relationships are the "lubricant", the facilitating medium, to helpproblem solving on a two-way information street between Owners, Engineers, Contracttors and, at times, Taxpayers. To do this, I believe we must use our telephones (who says they're antiquated?) and, if there's a pinch problem, we must even get into our car or truck or get onto a plane and go and meet the PERSON in need or to whom we must seek/ask something BEFORE it becomes a crunch situation, That is, we and the "other side" get to know one another and the future rapport and other forms of exchange benefit immensely from this solid human interaction. Let's use all the technology available to us, but continue to use phones and meetings, even when there is no major problem. This helps reduce anxiety, high blood pressure and to keep a smile on our dial.. . .
