Project Summary
Project Overview:
Crux served as the EPC foundation Engineer of Record on phases B, I, C, E, F and G of Florida Power & Light’s 500 kV Rebuild projects. The projects are intended to replace aging infrastructure and increase reliability in the region. Crux’s scope included oversight of the geotechnical program, as well as development and execution of foundation designs for new structures. In total, drilled shafts were installed support approx. 1,400 new H-Frame structures.
ProTRAQ™ Use:
These projects provide the most transparent view into the value ProTRAQTM can add, as it was developed and implemented between two phases which are easily comparable with few external variables. ProTRAQTM was not utilized on Phase B – the first phase of the project Crux completed – but was implemented on Phase I and subsequent phases.
As demonstrated in the table below, the average site commercial closeout time was reduced from 146 days to 42 days between the two phases. Though not the only contributing factor, the primary driver was the use of ProTRAQTM, which allowed for digital field construction data to be collected and
converted into compliance forms. Reducing the time required to complete close-out documentation
allowed final invoicing and release of retainage to occur much earlier than the previous phase.
| Report Submission Timeline | Phase B (No ProTRAQ™) | Phase 1 | Unit |
|---|---|---|---|
| Submitted 0 – 60 Days | 24 | 734 | Each |
| Submitted 61 – 120 Days | 74 | 73 | Each |
| Submitted over 120 Days | 152 | 11 | Each |
| Average Submittal Time | 146 | 42 | Days |
* Specification required closeout submittal within 60 days of foundation completion
Importance of a strong Quality Management plan:
The value of ProTRAQTM hinges on the implementation of a comprehensive QMP. Crux worked with FPL between Phases B and I to develop such a plan, and execute it in tandem to ProTRAQTM. The tool is a key component of a successful QM plan, providing a means to collect, review, and distribute quality data and documentation in real time which allows the construction crews to react to potential issues when it’s still possible to correct.
