The Tioga Dam project involves the procurement of plans, profiles, sections, and details for various drainage systems and protective works associated with the dam and its surrounding features. The main objective is to design and implement an effective drainage system to ensure the stability and safety of the dam structure and its abutments. Key components of the procurement include the inspection, maintenance, and installation of drain systems at the left abutment, right abutment, and downstream and upstream locations. Figures provided in the document illustrate the current drainage systems, outlet works, and stilling basin, as well as the proposed locations for the new drain systems. The scope of work for this procurement involves surveying, designing, and providing detailed plans and profiles for the drainage systems, including storm drains, outlet works, and associated structures such as manholes and inlet structures. The contractor will also be responsible for ensuring the integration of the new drainage systems with the existing outlet works and stilling basin. While contract details are not specified, the successful vendor will need to demonstrate expertise in hydraulic engineering, dam safety, and civil works construction, with a strong focus on drainage system design and implementation. Key dates and evaluation criteria are not provided in this extract, but the technical capabilities and experience of vendors in delivering similar projects will likely be paramount in the selection process.

The Mansfield Levee project involves the design and construction of a comprehensive flood protection system, as detailed in Appendix B. The file contains plans, profiles, sections, and inspection feature details for the levee and its associated structures. The primary objective is to construct a levee system with toe-drain pipes and manholes between stations 34+25 and 152+25. This includes the installation of drainage structures and pump stations at specific intervals along the levee to manage water flow and prevent flooding. Figures 18-37 provide visual representations of the levee alignment, inspection features, and technical details. The scope of work for contractors includes designing and constructing the levee, toe-drain system, drainage structures, and pump stations, ensuring they meet the specified standards and requirements. The successful vendor will also be responsible for providing detailed plans, profiles, and sections, as well as any necessary inspections and maintenance to ensure the levee's effectiveness and safety. While contract details and evaluation criteria are not specified in the provided text, the technical aspects of the procurement focus on flood protection infrastructure and water management solutions for the Mansfield Levee project, ensuring the selected contractor delivers a robust and reliable flood defense system.

This appendix provides a comprehensive visual reference for the Tioga Dam project, offering a series of photos that detail various structural elements. The procurement objective is not explicitly stated, but the focus on abutments, drainage systems, and the stilling basin indicates a potential need for maintenance, repair, or upgrade work. Specifications and requirements are implied through the visual documentation, highlighting the current state of the dam's critical components. The scope of work for vendors or contractors would likely involve tasks such as inspecting and assessing the condition of the structures, developing repair or refurbishment plans, and executing those plans to ensure the dam's integrity and optimal functionality of its drainage systems. While contract details and key dates are not provided, the extensive photo documentation suggests a thorough evaluation and planning phase, ensuring that any proposed work aligns with the unique characteristics of the Tioga Dam and its surrounding infrastructure.

This appendix provides a visual record, through a series of photographs, of the Mansfield Levee, a flood control structure. The photos capture various structures and pipes associated with the levee, including drainage systems, pump stations, and outlet structures. The procurement objective is to engage a contractor to perform video inspections of the discharge pipes from Pump Station 1, as indicated by the final photo and its caption. This inspection service is a critical component of maintaining the functionality and integrity of the levee system, ensuring that the pipes are clear and functioning properly to allow for effective floodwater discharge. While there are no explicit specifications or quantities mentioned, the scope of work for the contractor would involve utilizing specialized equipment to conduct a thorough video inspection of the pipes, identifying any blockages, damage, or maintenance issues. This would likely involve working in conjunction with levee operators and engineers to ensure the inspection is comprehensive and that any issues are properly documented and addressed. No contract details or key dates are provided in this excerpt, but the evaluation criteria for the contractor's proposal would likely focus on their experience with similar inspection projects, the quality and reliability of their equipment, and their ability to provide a detailed and accurate assessment of the pipe's condition. In summary, this section of the RFP centers on procuring video inspection services for the discharge pipes of Pump Station 1 as part of the ongoing maintenance and management of the Mansfield Levee. The photos included in the appendix offer a visual reference to prospective contractors, highlighting the specific infrastructure components that are integral to the proper functioning of the levee system.

The U.S. Army Corps of Engineers seeks a contractor to perform video inspection and cleaning of drainage systems at the Tioga Dam and Mansfield Levee in Pennsylvania. The work involves inspecting and cleaning various drain pipes, outlets, and associated structures to ensure proper functioning and maintenance. The contractor must provide all labor, equipment, and materials to complete the scope of work, which includes: At Tioga Dam: - Inspecting and cleaning an 8-inch tile drain on each side of the Outlet Works Structure, with a total length of approximately 1,800 feet. This includes locating the exit point of the drain and maneuvering the camera through bends in the pipe. - Inspecting and cleaning a storm drain system (left abutment drain) with a total length of about 2,065 feet, including associated manholes and inlet structures. - Inspecting two drainage lines at the right abutment: a 36-inch storm drain pipe (Right Abutment Upstream Drain) and an underground drainage system with a 36-inch perforated pipe (Right Abutment Downstream Drain), totaling about 2,400 feet in length, along with associated manholes. At Mansfield Levee: - Inspecting and cleaning a toe-drain system with a perforated steel pipe varying from 12 to 21 inches in diameter, totaling about 10,650 feet in length, along with associated manholes. - Inspecting drainage structures and pump stations: Drainage Structure No. 1 with 84-inch pipes, Drainage Structure No. 2 with a 48-inch pipe and a 72-inch gravity drainage pipe, and three pump stations with discharge pipes ranging from 10 to 16 inches in diameter, along with associated manholes and control structures. The contractor must also: - Remove sediment, rocks, debris, and vegetation from specified pipes and manholes. - Prevent flushed sediments and other materials from entering the downstream river channel using sediment control measures. - Provide detailed documentation of the inspection results, including logs, reports, photographs, and video recordings. - Submit a work plan detailing equipment, estimated dates, and water source for the cleaning and inspection. - Comply with security, safety, and environmental regulations, including the Corps of Engineers Safety and Health Requirement Manual. - Work within specified hours and coordinate with the Dam/Levee Operator to ensure uninterrupted project operations. The work is expected to commence within 365 days of the award, and the contractor must coordinate the start date with the COR. The contractor will be required to meet insurance, invoicing, and other administrative requirements as outlined in the RFP.
