GENERAL REQUIREMENTS

PART 1 GENERAL

1.1 GENERAL

This section comprises an explanation of the general contract requirements needed to accomplish the work. All work specified herein shall be accomplished in accordance with the procedures prescribed in the specifications and drawings.

1.2 COORDINATION CONFERENCES

Routine coordination conferences will be scheduled by the Contracting Officer throughout the life of this project. Coordination conferences will be held to discuss contract administration, Contractor quality control, phasing, scheduling, and other aspects relating to this construction. The Corps of Engineers and the Contractor will be represented at each of these meetings. Coordination conferences will be scheduled to occur when notified by the Contracting Officer.

1.3 PARTNERING

In order to most effectively accomplish this contract, the Government urges the Contractor to join the Government in establishing a cohesive and professional project management team. Through this "partnering" relationship both entities would strive to draw on the strengths of each organization for the ultimate goal of assuring that the project’s intended results are achieved, within budget and on schedule. This endeavor seeks an environment that nurtures team building, cooperation and trust between the Government and the Contractor. The partnering relationship would be bilateral in make-up, and participation will be totally voluntary.

The first step in initiating the concept would be a joint project management team "partnering" conference attended by multiple officers from each organization representing management and the key jobsite staff of each entity. The initial conference would be held within the first thirty

(30) calendar days following contract award. The Resident Engineer would chair the conference, establish its agenda and distribute minutes of the meeting. A professional facilitator acceptable to both parties would lead the participants of the session, through the steps of team building and the formation of a problem solving mechanism within the group. The conference duration would be no more than one day. Location of the conference would be offsite within a 60 mile radius of the jobsite at a facility which offers conference rooms and food service. All costs in connection with rented facilities and the facilitator would be shared equally by the Government and the Contractor. Each organization would pay other costs of its respective employees attending the conference.

Additional partnering sessions would be held no less than biannually.

Implementation of the partnering concept and philosophy would be an on-going process

1.15 TOOLS AND PARTS CONTROL AND ACCOUNTABILITY PROCEDURE

1.15.1 Purpose

Provide tools and parts control and accountability.

a. Tool and parts control and accountability, including personal items, are necessary to ensure that foreign objects are not left loose within the confined areas, defined as the inside diameter or the air housing above the lower bearing bracket.

b. Loose objects inside the above-described area are not desirable, and inspections must be conducted to ensure that loose objects are not left in place.

c. Pieces of equipment are stored and/or repaired/replaced inside and outside the confined area. There is not a practical means of controlling all access to the equipment outside the confined area and therefore control of tools, small parts, and other foreign objects outside the confined area is not practical.

d. Tools, parts, and personal items will be controlled and accounted for. Tools, parts, and personnel should only access the confined area from the balcony, the turbine pit access, and air housing door. The Contractor shall be responsible for overall control of tools, parts, and people. The Government construction representatives will ensure compliance by Government personnel and Government visitors.

e. Special meetings to announce start of this control and to emphasize performance for every

1.15.2 Inspections

One will be conducted jointly with Contractor and Government personnel.

a. The confined area will be inspected independently by each representative of the Contractor and Government personnel after all repairs/replacements are made to the stator.

b. All equipment will likewise be inspected independently by the Contractor and Government after all repair/replacement and just prior to reinstallation.

c. Personnel will remove all personal items and tools from their person prior to making the inspections. Removal of the personal items

SECTION 01 10 10 Page 10 will be verified by the Contractor's representative.

d. At the end of each shift, during reassembly, the Contractor's supervisor will inspect the area within the air housing inside the diameter and above the lower cover plates for any loose tools and parts.

Loose tools and parts will be removed and accounted for each day. No personnel will leave the area until everything logged into the confined area is logged out of the area.

e. The confined area will be independently inspected by the Contractor and Government personnel just prior to reinstallation of the upper and lower air deflectors. A cleanout inspection procedure/plan will be developed with the Contractor and the Government. A trial inspection will be utilized to fine tune the procedure. In addition, just prior to unit startup, and independent inspection by the Contractor and Government personnel will be performed on all those still visible within the confined area.

1.15.3 Tools, Parts, and Personal Items Control and Accountability

a. To control the tools entering the confined area, all personal transportable tools will be checked out of a controlled space, such as large tool bins or fenced cages, and checked back in on each shift. A dedicated tool person (laborer) on each shift will be responsible to assure that inventoried tools for each end of each shift. The inventory will be specified; that is, each tool will be identified for each craftsperson by the tool person. Should a tool be lost during the shift, the craftsperson will be directed to find the tool before he is allowed to leave the site.

b. To control small personally transportable parts entering the confined area, the dedicated tool control person will inventory and issue the parts at the start of each shift. At the end of each shift, a count will be made of the installed parts to ensure that the number checked out was actually installed. The Contractor's supervisor will reconcile any shortage of small parts

1.15.4 Responsibility and Records

a. The Contractor's supervisors will be responsible that all tools are accounted for and signed in and out on a daily basis.
