Repairs to Cabras #4 Power Plants
This project was awarded to Black Construction Corporation for $2.44M to replace and restore equipment and facilities damaged by a fire at the GPA Cabras No. 4, 40MW baseload generator. As a result of GPA’s demand for a reserve baseload generator, the contract required the completion of all work within 120 calendar days from the Notice to Proceed.
Another significant factor for achieving the contract completion date was a $15,000 a day penalty as liquidated damages for all days worked beyond the contract completion deadline.
The scope of work for the Cabras #4 Power Plant consisted of the following replacement and restoration of equipment and facilities:
