Subject: Request for Change Order: Engineering for Doctors and Wiggins Passes Dredging
Contract No. 17-7128, Purchase Order No.45-179399, and Project No. 195-90549
This is a request for a change order to the above listed purchase order with Aptim Environmental &
Infrastructure. Inc (APTIM). APTIM requests that the purchase order be increased by $29,028 35 from
the current price of$149,988 94 to a new price of$179.017 29, and the time be extended 30 days with
a new completion date of November 17. 2018 The principal reasons for this request are that the
contractor is taking longer than anticipated. largely due to weather and mechanical delays, increase in
scope of work and implementing changes to address sea turtle issues
Additional engineering work was required in preparation for this project APTIM assisted the County in
coordinating with permit agencies for a 50 foot northern shift in Wiggins' interior channel location to
address persistent morphological trends. The bidding period was longer than usual and APTIM
provided professional support to answer additional bidder questions during this time
The projects construction phase began on March 14 and 16. 2018 with the pre-construction survey
and meeting, respectively The construction commencement for Wiggins Pass was announced for April
2 and actual construction began April 18 Construction on Wiggins Pass was substantially completed
on July 20. Construction at Doctors Pass began on August 3, and is approximately half done as of
August 12. Completion for the entire project was initially planned for Spring 2018.
The contractor took longer to finish the Wiggins Pass segment due to weather, mechanical and
technical delays The contractor's planned start of construction was April 2 and was substantially
completed on July 20. for a total of 109 days During this period, there were 58 active dredging
days. The Wiggins Pass construction was about 1 month longer than anticipated in our APTIM scope
of work, and required additional engineering due to the lack of contractor progress.
Although Hurricane Irma struck Collier County on September 10. 2017, the inlets were not surveyed
post-storm until the contractor's pre-construction surveys Once these pre-construction surveys were
taken, it was evident that conditions had changed significantly since the 2017 physical monitoring
surveys due to the Hurricane At Wiggins Pass, there was a change in location of the hydraulic plug
and the total dredge volume increased by 2.000 cy. with a shift of 4,000 cy to the interior channel
sections. APTIM assisted the County in making changes to the Wiggins design to keep within the
Wiggins Pass bid price
16A11 6 A
A APTIM
At Doctors Pass,the pre-construction conditions revealed an 11,000 cy increase in dredge volume and
a decrease in the capacity of the single disposal area APTIM will provide professional services to the
County to cover the extended active construction period required to dredge the increased Doctors Pass
volume. In addition, the longer construction period at Wiggins Pass resulted in the need to dredge
Doctors Pass during the middle of sea turtle nesting season. This change in timing required
extensive preparatory work and coordination to support the County's coordination with
environmental stakeholders and permitting agencies. The resulting circumstances required a re-
design of the construction plans, additional surveys at Lowdermilk Park, and a new Notice to
Proceed from FDEP. The new design was completed to incorporate a second disposal area at
Lowdermilk Park,to accommodate in-water only disposal and special handling of the dredge pipeline
to avoid sea turtle nests that could not be relocated prior to construction.
This new work significantly increased both the time and complexity of the effort required to bring the
project to completion. Our estimate to complete these additional efforts is$29,028 35 on a time and
material basis, as a change order to the subject purchase order. Attached you will find our fee
spreadsheet in support of the requested change order
