Abstract

Methods and systems for optimizing pile design based on pile driver data are provided. A pile driving performance monitoring (PDPM) system captures pile driver data for a pile in an identified location using a pile driver data capture device. The pile driver data comprises a pile penetration depth and pile penetration rate based on percussive hammer. The identified location can be determined using a global positioning system. A parsing program component analyzes the pile driver data for the pile. The parsing program component determines whether the pile driver data of the pile meets an anticipated-pile driving criteria, the anticipated-pile driving criteria comprises a test pile driver data that correlates with a predefined capacity for a pile in the identified location. The pile is added to an acceptance report when it meets the anticipated-pile driving criteria or added to exception report when it does not meet the anticipated-pile driving criteria.

identifying a location to drive a pile;

determining that the location to drive the pile corresponds to an anticipated-pile location, wherein the anticipated-pile location is associated with an anticipated-pile driving criteria;

capturing pile driver data for driving the pile at the location using a percussive hammer, wherein the pile driver data comprises a pile penetration depth and a pile penetration rate based on percussive hammering;

analyzing the pile driver data to determine whether the pile driver data of the pile meets the anticipated-pile driving criteria, wherein the anticipated-pile driving criteria comprises at least a test pile driver data that correlates with a predefined capacity for an anticipated-pile in the identified location; and

generating a report for the pile, wherein the report is based on the analysis to determine whether the pile driver data meets the anticipated-pile driving criteria.

2. The method of claim 1 further comprising, assigning a location name of the anticipated-pile location to the pile driver data to correlate the pile driver data with the anticipated-pile location.

3. The method claim 1, wherein the anticipated-pile driving criteria for the anticipated-pile location is generated based on:

capturing test pile driver data for a test pile using a test percussive hammer, wherein the test pile driver data comprises a test pile penetration depth and a test pile penetration rate based on percussive hammering; and

determining the anticipated-pile driving criteria based on the test pile driver data, wherein the anticipated-pile criteria includes a vertical capacity and a lateral capacity.

4. The method of claim 1, further comprising determining a hammer status, wherein the hammer status at least indicates whether the hammer is activated, such that, capturing the pile driver data is started.

5. The method of claim 1, further comprising determining a hammer status, wherein the hammer status indicates a height of the hammer, wherein the height of the hammer is used to determine a push depth of the pile, such that, the push depth is appropriately factored into the analysis of the pile driver data, wherein the push depth indicates a depth to which the pile is pushed into the ground without the hammer being turned on.

6. The method of claim 1, wherein the predefined capacity comprises a vertical capacity and a lateral capacity.

7. The method of claim 1, wherein generating the report comprises generating an acceptance report when the pile driver data meets the anticipated-pile driving criteria.

8. The method of claim 1, wherein generating the report comprises generating an exception report when the pile driver data does not meet the anticipated-pile driving criteria.

9. The method of claim 8, further comprising receiving an indication to remove the anticipated-pile from the exception report to an acceptance report when proof testing and remedial measures based on the pile driver data indicate that the anticipated-pile meets the anticipated-pile driving criteria.

10. The method of claim 1, further comprising providing access to the pile driver data via a communication interface, wherein the communication interface allows access to analysis information and updates to the anticipated-pile based at least in part on external resources.

11. A pile driver data capture device, the device comprising:
