Corpus Christi Ship Channel, Texas, Upper Bay Reach in Nueces County, Texas, Channel Improvement Project.

7 OCT 2020 - Uploaded Upper Bay Reach Data Report. 6 OCT 2020 - Uploaded one Geotechnical Investigation File for DMPA 2 and one Data Report File for CB-61 thru CB-85. THIS IS NOT A SOLICITATION FOR PROPOSALS AND NO CONTRACT SHALL BE AWARDED FROM THIS SYNOPSIS. The U.S. Army Corps of Engineers (Corps), Galveston District, is requesting input from government, industry, and other parties for an upcoming dredging project. The Corpus Christi Ship Channel, Texas Channel Improvement Project Contract 3 - Upper Bay Reach is a project that proposes to deepen and widen the existing main channel from station 70+000 in the Upper Bay Reach, just west of La Quinta Junction, towards Optional Inner Harbor dredge reaches (e.g. Avery Point area and Chemical Basin), if exercised. Other elements of proposed project construction involve dredging of new barge lanes, open-water disposal, and incremental raising of existing perimeter dikes at existing upland placement areas (e.g. Placement Areas 1-2; 3A and 3B) with associated drop-outlet structure modifications. Optionally, further proposed construction activities may involve removal of buried pipeline crossings from federal navigation channel template limits, if exercised. When considering Base and Options the project dredging is anticipated to encompass approx. 11.6 miles of main channel. The majority length of Upper Bay channel dredging work is starting past the La Quinta Junction and ending before reaching the Inner Harbor bridge. This segment of Upper Bay channel will include new barge lanes on both sides of Bay Reach. The project involves dredging maintenance material of the existing channel to the -47 feet Mean Lower Low Water (MLLW) template and dredging new work type material for the new channel -54 feet MLLW template. The total maintenance material from the existing project template is estimated to generate 2.4M cubic yards (CY). Dredging of the new work material for fully deepening and widening channel project (e.g. authorized depth and advanced maintenance) is estimated to generate 11,100,000 CY. The preliminary estimated completion time for base work (e.g. Schedule No. 1) is 496 days. If all proposed project options are exercised the project duration is estimated at a total of approx. 687 days. The assumed dredging plant type equipment and dredging rate is based on pipeline production. Available geotechnical information is displayed on the Corp of Engineers project plans. Attachments: 1.

(CDT) on October 7, 2020. Email your response to Ms. Lucille Smith at contact@example.gov and Mr. Curtis Cole, Jr. at contact@example.gov . 1. Based on the proposed plan shown, what means of construction would you likely employ? 2. What can we change in the plans and specifications to reduce cost and/or durations? 3. What are the biggest risks you see in the proposed plan and how the Contractors would propose mitigating the risks? 4. What type of equipment do you have access to too perform this project? 5. Based upon the provided geotechnical data and your expertise, what percentage of dredge material would remain where placed (retention) during work (e.g. open water placement (OWPA) and/or filling OWPA's 14-17 across bay)? Which retention structures / methodologies would be most effective given your experience / equipment? Also include information such as: Company name, address, e-mail, telephone number, and points of contact. INDUSTRY DAY NOTE: Below are Breakout Session time slots.
