a. The trees must be protected from wounds to the bark and foliage.

b. The critical root zone must be protected from compaction and grading.

c. Changes in temporary site drainage and ponding that affect the protected trees must be minimized to the extent possible.

The critical root zone of trees designated to be protected must be surrounded by a high visibility fence 4 feet in height, supplied and

SECTION 01 14 00.00 13 Page 3 erected by the Contractor. The critical root zone must be defined by an area extending 1.5 feet radius from each tree for each inch of Diameter at Breast Height (DBH). The fence must be securely erected and installed prior to any movement through the project site by construction vehicles or equipment, and remain in place until construction and clean-up are completed. The critical root zone must remain free of all construction activities including trenching, staging, stockpiling and storage of materials. Vehicles and equipment must not drive or park within the critical root zone. Variation to the critical root zone size or configuration will only be permitted where it is absolutely necessary for construction of the project, and requires approval of the Contracting Officer. Short duration alterations of the critical root zone involving wood chips and limited equipment travel must be submitted in writing for approval.

The Contractor must not operate equipment in vegetated areas outside the work limits.

3.2.1 Restoration of Damaged Trees

Any existing tree designated to be protected that is damaged by the Contractor's operations must be replaced. Trees will be considered damaged if the critical root zone in cohesive soils is compacted, if there are significant wounds that could contribute to rot, or if distress (evident by reduced growth or other observations of distress documented by a forester) is observed prior to closing the contract. Trees must be replaced in kind on a caliper inch per caliper inch basis (DBH) (e.g. one 6-inch red oak must be replaced with two 3-inch red oaks, three 2-inch red oaks, or six 1-inch red oaks). Replacement tree size and location will be determined and staked by the Contracting Officer. Repair by pruning, aeration, soil conditioning, or other recommendation from a qualified forester will be considered by the Contracting Officer for substitution for replacement.

3.3 DEFINED NON-NAVIGATION SEASON

The Lock and Dam No. 2 will be closed to navigation generally from early December to early March, weather dependent. The Non-navigation window during the winter of 2024/2025 are as follows:

Construction will not start prior to 9 December 2024 however the staging area will be available for pre-construction activities.

3.4 CONTRACTOR PROPOSED DISPOSAL AREAS

Any disposal sites proposed by the Contractor that are not already identified by the Government as approved for this project are subject to approval by the Contracting Officer. This approval process may require the Government to prepare an environmental assessment at no cost to the Contractor. This may require additional review time and may result in additional requirements to offset environmental effects associated with the use of the site. Proposed sites which involve the excavation or placement of material within a cultural site, wetland, wooded area, floodplain, or other environmentally sensitive area will not be approved.

SECTION 01 14 00.00 13 Page 4

3.5 PRE AND FINAL DIVING INSPECTIONS

The Contractor must perform a diving inspection of the river bottom at and around the nose pier and adjacent monolith of the upper guide wall prior to the start of any work on removing the portions of the upper guide wall. This inspection must verify and record the nose pier and adjacent monolith conditions, river bottom conditions, and to search for any obstructions that may delay or impact construction of the project features. The obstructions include but are not limited to concrete, riprap, pieces of reinforcement, timber debris, and miscellaneous sheet piling.

The Contractor must perform a final diving inspection of the nose pier, adjacent monolith, and river bottom out as far as 20 feet from the wall.

The purpose of the final inspection is to enable visual verification of the conditions of the new nose pier concrete placement, the guide wall/ nose pier transition, and to serve as a baseline for future inspections.

The pre and final diving inspections must consist of, but are not limited to a high definition video recording (720p or better) and acoustic imaging.

The videos must be of a quality that will allow the Government to readily assess site conditions at the time the videos are obtained. Videos where factors such as lighting, focus, and clarity do not allow for the Government to clearly evaluate site conditions must be reshot at no additional cost to the Government. Configure the high definition video to include on-screen titles such as time and date, and narration between the diver and surface observer.

3.6 NAVIGATION NOTICE

The main lock will be open to full width and length navigation, except as indicated in the Defined Non-Navigation Season paragraph above. Should the contractor fail to complete all work in accordance with clause 52.211-10, the contractor shall, at its expense, implement a Navigation Plan that outlines the means and methods for providing navigation assistance. Once the Contractor's plan is approved, the Government will provide public notice of the construction and any approved restrictions.

Changes or substitute measures to the plan must be submitted 7 days prior to actual implementation and be approved by the Contracting Officer.

3.7 NAVIGATION PLAN

Establish and maintain a plan to ensure the safety of industry and recreational traffic in the construction area. This plan must include actions as required to protect the public and prevent damage to the incomplete construction. The Contractor must be responsible for coordinating with the Coast Guard and other regulatory agencies to implement any necessary restrictions. The Contractor must also develop and implement a plan to provide public notice of any construction and any necessary restrictions and closures as well as the availability of the helper boat for assistance to tows passing through the lock.

3.7.1 Navigation Assistance

Provide a helper boat to assist navigation within one-half mile upstream of Lock and Dam No.2. The helper boat must be alongside tows entering and exiting the lock and when passing construction areas and must offer any other assistance to navigation as necessary. The purpose of this assistance is to:

a) Protect life of working personnel.

b) Protect incomplete construction works from potential damage due to barge strikes.

SECTION 01 14 00.00 13 Page 5

c) Protect navigation interests from damage and delays associated with ongoing construction.

d) Assist passage through the area where modified approach conditions impact the ability of vessels to safely transit the construction area and approach to the lock.

3.7.1.1 Minimum Helper Boat Requirements

Provide a helper boat and crew, including at least one deckhand, for navigation assistance. The helper boat must be a twin screw push boat with a minimum of 1,000 horsepower. Assistance must be provided in coordination with the tow boat operator to ensure proper assistance is being provided.

3.7.1.2 Helper Boat Availability

In accordance with Paragraph 3.6 above, the helper boat must be available 24 hours per day, 7 days per week, including holidays. Helper boat assistance must continue until all work is complete and accepted by the Government. For the purposes of this requirement, the Contractor is advised that areas upstream and immediately adjacent to the existing guidewall are used for vessel approach. Therefore, any feature or obstruction in this area is considered to present a hazard to navigation and requires the availability of a helper boat. Vessels may elect not to use the helper boat; however, the service must be present to assist if needed.

3.7.1.3 Government Vessels

Government Vessels may also be required to transit the lock and construction area at any time during the navigation season. The Contractor is required to provide a helper boat to the site to assist Government Vessels. Vessels under contract to the Government are considered Government Vessels.
