4. Wherever a reference to number of days is noted, it shall be construed to mean working

days.

SEQUENCE OF CONSTRUCTION

1. The facilities will be maintained in continuous operation by the Owner during the entire

construction period of this contract. Work under this Contract shall be so scheduled and

coordinated by the Contractor that such work will not impede the wastewater treatment

plant operation or cause odor or other nuisance. In performing the work shown and

specified, the Contractor shall plan and schedule his work to meet the operating

requirements and all additional restrictions.

2. The following sequence of construction describes simplistically, the major events required

to complete the work in the preferred order of completion.

3. The order of events is designed to minimize disruption to the ongoing operation of the

existing treatment facility. Any proposed deviation from the schedule order must be

submitted in writing to the Engineer and approved by the Engineer.

A. Installation, testing, and approval of the temporary bypass pumping system .

B. RAS discharge piping modifications.

C. RAS discharge piping testing and approval. (three day operational test).

D. Demobilization of the temporary bypass pumping system.

E. Isolation of knife gate valves serving final clarifiers 3 and 4 from flow. This item shall

be coordinated with City staff. It is not anticipated that temporary bypass pumping

will be required for this portion of the Work. It is estimated that isolation from flow will

take approximately 2 days to accomplish.

F. Installation of the isolated knife gate valve (total of 2).

G. Isolation of knife gate valves serving final clarifiers 1 and 2. This item shall be

coordinated with City staff. It is not anticipated that temporary bypass pumping will

be required for this portion of the Work. It is estimated that isolation from flow will

take approximately 3 to 7 days to accomplish depending on the operating condition

of the WWTP.

H. Installation of the isolated knife gate valve (total of 2).

4. Coordination with Owner Personnel. The Contractor shall notify the Owner before

commencing work involving removing or placing in operation existing or new facilities.

A. Only the Owner can authorize the shutdown of any portions of the facility or system.

The Contractor shall, under no circumstances, interfere with any existing component

OWNER USE OF THE PROJECT SITE

1. The Owner may utilize all or part of the existing facilities during the entire period of

construction for the conduct of the Owner's normal operations. The Contractor shall

cooperate with the Owner to minimize interference with the Contractor's operations and to

facilitate the Owner's operations.

PROJECT MEETINGS

1. Preconstruction Conference: Prior to the commencement of work at the site, a

be attended by the Contractor, its superintendent, and its subcontractors as appropriate.

Other attendees will be:

A. Engineer.

B. Representatives of Owner.

C. Others as requested by Contractor, Owner, or Engineer.

2. Unless previously submitted to the Engineer, the Contractor shall bring to the conference

one copy each of the following:

A. Preliminary schedule.

B. Preliminary Shop Drawing/Sample/Substitute or “Or Equal” submittal schedule.

3. Progress Meetings: The Engineer shall schedule and hold regular on-site progress

meetings at least daily and at other times as requested by Engineer. The Contractor,

Engineer, and all subcontractors active on the site shall be represented at each meeting.

Contractor may at its discretion request attendance by representatives of its suppliers,

manufacturers, and other subcontractors. At a minimum, the Contractors Superintendent

shall be present at each meeting. The Contractor's Project Manager shall be required to
