Attachment 01 – MZB VOR Mission Bay Island Investigation Report

1. Introduction This exhibit sets forth the scope of services to be covered by the subcontract. The purpose of this exhibit is to identify the scope for which the Design-Builder is responsible.

The Design-Builder must design the repair and restoration of the existing deteriorated seawall located at the MZB VOR in San Diego, California, with particular focus on schedule, budget, environmental and quality and coordinate activities with FAA, United States Army Corp of Engineers (USACE), site facilities manager, QC/QA manager and authorities having jurisdiction to achieve the required service dates and a successful turnover and outcome.

The Design-Builder must identify and price all elements necessary for the actual repair and restoration work.

2. Project Description

Reference Attachment 01 – MZB VOR Mission Bay Island Investigation Report

The MZB VOR Mission Bay Island has four main shoreline failures, three on the northern side and one on the southern side of the island. The Design-Build contractor will be responsible for all aspects of design and construction, considering all appropriate environmental regulations and procedures, to repair the damaged seawall.

The proposed repair concept for these four failure areas incorporates a geotextile filter fabric underlayer on top of which the underlayer rock and armor rock will be placed. Underlining the proposed repair areas with geotextile filter fabric reduces the possibility of seepage-induced erosion and the potential effects of scour and/or winnowing. Due to the limited wave forces at the site (excluding smaller wind / boat wake waves), it is recommended that two layers of armor stone be placed on a 1V:3H slope with a minimum layer thickness of 2 ft. Additionally, a minimum 0.5 ft layer of stone be placed on the geotextile filter fabric following the alignment of the existing topography as a bedding underlayer, though the underlayer thickness will vary and increase to obtain the required design crest elevation while staying relatively within the existing footprint.

It is also expected that new larger stones be placed at the toe, and that any existing rock that was displaced since the original construction be left in place. The larger rock at the toe will enhance the structural stability and mitigate potential future toe scouring overtime. If additional site-specific analysis are required to ensure proper design solution, the contractor will notify the FAA and include the cost in the bid proposal.

The Least Tern nesting seasons, which restricts the construction season, is of particular importance. The Least Tern nesting season runs from April to September, no construction activity is allowed, therefore it is required that any project physical activities taking place at the site must start and finish within the time frame from October 2022 to March 2023. Other project activities not taking place at the site can be outside of that window. The areas identified on the island as Least Tern nesting locations, are not to be disturbed by construction activities, including personnel access.

The MZB VOR location is an island in the San Diego Mission Bay and surrounded by residential dwellings.

Access to the island is via boat. The contractor will investigate transportation means and method for materials and equipment onto the island. No materials or equipment are allowed to be stored on the island.

The island dry ground will be restored to its original conditions before final acceptance of the project.

The work includes but is not limited to:

2.1 Design Phase:

• The Design-Builder must perform a complete and thorough hydrographic and topographic survey to establish horizontal and vertical control to establish design parameters.

• The Design-Builder must design and install the rock within specified tolerances, as typical for this type of seawall

• New design must repair all failure areas

• The Design-Builder must comply in design with State, federal, FAA, United States

Fisheries and Wildlife (USFW), City of San Diego, USACE Environmental regulations, standards, specifications and requirements.

2.2 Construction Phase

Within 5 days of receiving the Authority’s comments, the Design- Builder must schedule a meeting with the FAA to disposition the comments. Once the meeting is held, the Design- Builder must incorporate the agreed upon changes into the documents and prepare the final submittal.

9.12 Final Design Submittal Package

The final design submittal package must consist of the design documents including specifications, calculations and reports that demonstrate compliance with the contract requirements, and other information necessary to allow the Design-Builder to coordinate and complete the construction of the project.

The FAA must review the submittal and, within 21 calendar days, notify the Design-Builder of its acceptance or rejection of the package. If the package is accepted, the Design- Builder can proceed to construction.

If the package is rejected, the Design-Builder must make the changes identified by the FAA and resubmit until the package is acceptable to the FAA.

9.13 As-Built Drawings

The Design-Builder must provide the FAA with one electronic copy (in AutoCAD editable format), one set of full sized bond drawings and two half sized copies of the final project record drawings that have incorporated all field changes.

10. Environmental Natural and navigable waterway

Given that the seawall is located in a natural and navigable waterway, it is likely that an approved environmental permit may be needed from the FAA, USACE, WSFW and the City of San Diego. It is unlikely that the project would be prevented as a function of the USACE withholding a permit but there is a possibility that the USACE could require environmental mitigation such as planting sea grasses in the same waterbody at a different location. Implementation of the mitigation effort is to be included in the final design and completed by the Design-Builder. Therefore, the FAA recommends that early coordination with the USACE and the FAA be conducted to determine what considerations are to be implemented in the design. The construction phase must not commence until all permits have been procured and the FAA has made and determination on the National Environmental Policy Act (NEPA) documentation.

10.1 Deliverables

Final drawings depicting environmental concerns and remedies.

11. Construction Quality and Safety

The Design-Builder must implement quality and safety programs that fulfill the requirements set forth in the subcontract, OSHA and AHJ. The Design-Builder must submit to the FAA a copy of their full company safety program during the procurement process for review by the FAA.

The FAA specifically reserves the right to approve all Quality and Safety staff.

All submittals related to quality management and safety must be provided for FAA review and comment or approval.

12. Construction

The Design-Builder must construct the project in accordance with the approved final drawings and the technical specifications. Specific items of significance to the FAA are highlighted below;

this list of items is not all-inclusive and does not relieve the Design-Builder of the obligation to ensure that the project is completed in accordance with all contract requirements.
