2. Project Overview-Discussed by Vicki Twerdochlib

Project Overview o The project includes work in three distinct areas along the Omaha Levee. The three areas

are distinguished by “Relief Well Area” designations, which were assigned by USACE. These areas are referred to as Area D1, D2 and F. o Area D1 is located south of the airport and east of the Omaha Correctional Center. The

work being conducted here includes grading and modifications to a storm sewer system. Coordination is required at this work location with both the security teams at the Omaha Airport Authority and with the Omaha Correctional Center.

o Area D2 is located south of the Monarch Oil facility and west of the Omaha Correctional Center. The work being conducted here includes tree removal and grading. Coordination is required at this work location with both the Monarch Oil Facility and with the Omaha Correctional Center.

o Area F is located just north of Abbott Drive, south of the Magellan Tank Farm. The work being conducted here includes the installation of two new relief wells. Coordination is required at this work location with Magellan.

Existing site Important Design and Construction Issues

o Pilot Hole o In accordance with the requirements in Specification Section 33 26 00, the Contractor is

required to submit a relief well design. The information to support this design is detailed further in this same Specification Section – the information included in Appendix A can be used for design, the driller may elect to utilize the same procedures provided in the drilling program plan attached in that appendix for an additional pilot hole, or the driller may elect to submit a new drilling program plan. Submitting a new drilling program plan would be done at the Contractor’s risk with regards to schedule.

o Relief Well Drilling and Development o Contractor will provide the City’s inspector the schedule on the drilling. City is

providing the resident project representative (RPR) and HDR is providing design milestone field visits. A geotechnical engineer from HDR needs to be on site for the

Removing trees after March 1 requires the Contractor to have a biologist on site to comply with MBTA requirements.
