SECTION 00 70 00 - CONDITIONS OF THE CONTRACT

The following have been modified:

SCOPE OF WORK

SCOPE OF WORK

LOCK AND DAM 2

CABLE TRAY SUPPORT

PART 1 GENERAL

1. 1.1 PROJECT DESCRIPTION

The existing fiberglass cable tray in the riverward wall gallery was installed in 1995 during the Lock and Dam 2, Stage 2 Rehabilitation Project. Recently, it was discovered that approximately 350ft of the cable tray support system in the upper riverward wall gallery has failed, resulting in the cable tray falling to the gallery floor. There does not appear to be any damage to the existing cables or cable tray. Due to water infiltration into the gallery, the ideal time to repair the cable tray is during the Lock and Dam 2 dewatering scheduled for the winter of 2023/2024.

The scope of this project includes the repair of the cable tray and supports in the upper riverward wall gallery as well as reinforcing the entire cable tray support system in the riverward wall and landward wall galleries through the supply and installation of the items listed in Part 2 below and any incidental related work.

1.9 RESIDENT MANAGEMENT SYSTEM CONTRACTOR MODE (RMS CM)

The Government will use the Resident Management System (RMS) to assist in its monitoring and administration of this contract. The Government accesses the system using the Government Mode of RMS (RMS GM). The Contractor accesses the system using the Contractor Mode of RMS, referred to as the RMS CM, to record, maintain, and submit various information throughout the contract period. The term RMS will be used in the remainder of this section for both RMS GM and RMS CM. The joint Government-Contractor use of RMS facilitates electronic exchange of information and overall management of the contract.

RMS provides the means for the Government and Contractor to input, track, and electronically share information in the following areas:

Administration Finances Quality Control Submittal Monitoring Scheduling Closeout Import/Export of Data

4. 1.9.1 Contract Database – Government The Government will enter the basic contract award data in RMS prior to granting the Contractor access. The Government entries into RMS will generally be related to submittal reviews, correspondence status, and Quality Assurance (QA) comments, as well as other miscellaneous administrative information.

1.9.3 Contract Database – Contractor

Contractor entries into RMS will establish, maintain, and update data throughout the duration of the contract. Contractor entries generally include prime and subcontractor information, daily reports, submittals, RFI's, schedule updates and payment requests. RMS includes the ability to import attachments and export reports in many of the modules, including submittals.

1.9.4 Implementation

Use of RMS as described in the preceding paragraphs is mandatory. Ensure that sufficient resources are available to maintain contract data within the RMS system. RMS is an integral part of the Contractor's required management of quality control.

1.10 CONTRACTOR QUALITY CONTROL

Comply with NEMA VE 2.

Comply with NEC Article 392 for requirements that apply to the construction and installation of cable tray and cable channel systems. Provide products that are UL-classified and labeled with the UL classification mark.

Provide onsite quality control personnel for the construction and installation of the cable tray supports.

PART 2 PRODUCTS

2.1 DELIVERY STORAGE AND HANDLING

Deliver the specified products in containers with manufacturers name, labels, product identification, quantities, and contract award number intact. Store in a secured, dry, weatherproof location. Handle containers to avoid damage to products.

Coordinate delivery with the current Lock 2 Lockmaster Steven Heidbrider at (651) 290-5826.

Provide the Lockmaster with a date and time for the delivery at least 3 days in advance.

2.2 SYSTEM DESCRIPTION

Provide and install stainless steel cable tray supports in between existing supports and on either side of each monolith joint to supplement the existing load carrying capacity and meet NEMA VE 2 support spacing requirements. Provide and install cable tray supports and reinstall cable tray to repair the section of approximately 350ft of the cable tray support system that has failed.

Ensure associated cables are returned to their original trays following support and tray reinstallation. Both new and existing cable tray supports must be designed to prevent the trays from sliding or rolling off. Inspect the existing supports for signs of failure. After the contract is awarded but prior to starting work, the contractor will identify all existing supports that require replacement and submit to COR for approval. Once approved by USACE, a contract modification will be issued for the replacement of failing supports.

The existing cable trays are 10 feet in length and 12 inches in width. The cable tray support spacing ranges from 14 to 18 feet, averaging 16 foot intervals. The estimated quantities of additional supports required are listed below, however, the Contractor must field verify the quantities.

425 horizontal supports

138 vertical supports, 5 feet high on average (ranging from 2-6 feet)

Fasteners for each horizontal supports

Mounting anchors and grout for vertical supports

See Appendix A for existing cable tray layouts and support documentation.

2.3 ASSEMBLY PREPARATION

Before assembly, ensure that the finishes of edges, fittings, and hardware are free from burrs and sharp edges.

2.4 COMPONENTS

2.4.1 Supports

Provide an adequate bearing surface for the tray on the supports and ensure that the surface can accommodate hold-down clamps or fasteners to prevent vertical and horizontal movement of the cable tray. Provide a means, other than friction, for securely fastening cable trays to supports.

Design of the supports must prevent the trays from sliding or rolling off the horizontal bearing surface. Provide support for cable trays at intervals of 10 feet or less. Place supports for horizontal-elbow tray fittings within 2-feet of each fitting extremity and as recommended by the cable tray manufacturer. Place supports within 2-feet on both sides of each monolith joint and as recommended by the manufacturer. Ensure that the supports and fittings have a load-carrying capacity that is equal to or greater than that of straight cable tray sections (see Appendix A, page 5, Loading Requirements for loading details).

2.5 MATERIALS

Provide steel cable trays stainless supports and fasteners made of AISI Type 304 or Type 316 stainless steel.
