CONSTRUCTION SEQUENCING

1.01 SITE CONDITIONS

A. Several areas of construction under this contract must be coordinated with either the Plant Superintendent or Chief Operator at the water treatment plant and accomplished in a logical order to maintain the process flow through the plant and to allow construction to be completed within the time allowed by the Contract Documents. CONTRACTOR will also coordinate his activities with the other contractors, if any, to allow orderly and timely completion of all the work.

B. When access through construction areas must be disrupted, CONTRACTOR will provide alternate acceptable access for operation personnel or other contractors.

C. CONTRACTOR is required to coordinate his activities in the interface or common areas with other contractors and the operation personnel.

D. Various interconnections within the plant will depend on the closure of various valves. Many of these valves are old, may be difficult to operate, and may not seal properly.

E. Various interconnections within the plant may require temporary partial power shutdown.

CONTRACTOR will make every effort necessary to minimize the shutdown time and will coordinate with the CONSULTANT, plant operating personnel, and/or utility authorities at least five (5) working days prior to attempting any such power shutdown. Furthermore, CONTRACTOR will provide any corrective measure or temporary facilities necessary to perform the work at no additional cost to the CITY and without interrupting the plant operation. The CONTRACTOR shall submit a plan for each anticipated partial power shutdown.

F. Within the Schedule developed in accordance with Section 01310 of the Contract Documents, the

CONTRACTOR shall identify all periods of time during which existing facilities shall be taken out of service, either temporarily or permanently.

G. During Start-Up Testing, CONTRACTOR shall make available the staffing, labor, equipment, and manufacturer’s representatives required to make any necessary adjustments and training.

H. The work under this contract involves the removal of existing equipment with the replacement by new equipment. It is understood, therefore, that the CITY must allow reasonable scheduled shutdowns of the facilities in order to perform the necessary work.

Chemical Feed System Rehabilitation Bid 17 City of Dania Beach

I. Scheduled shutdowns will be made in those instances when it is necessary to shut off power in order to perform the necessary work. Prior to any shutdown, all materials and facilities shall be on hand, and any preparatory work necessary shall have been accomplished before any shutdowns will be allowed. The CONTRACTOR shall submit a plan for each anticipated partial power shutdown.

1.02 GENERAL CONSTRUCTION CONSTRAINTS

A. CONTRACTOR must not interfere with the operation of the water treatment plant or adjacent Facilities (Department of Public Works, Utilities and Engineering), during construction of the improvements except as shown in section 1.03 below.

c. Cleanup

1.05 EXISTING BELOW AND ABOVE GRADE FACILITIES

A. The Contract Documents may contain limited data relative to existing utility installations and structures above and below the ground surface due to lack of accurate records of these installations.

The CONTRACTOR shall notify the CITY/CONSULTANT, in writing, at least 10 calendar days in advance of the date he proposes to commence such work.

B. In case the CONTRACTOR’s operation disrupts the lime softening, except for such brief periods as expressly permitted and required, the CONTRACTOR shall at their own cost immediately make all repairs and replacements and do all work necessary to restore the plant to operation to the satisfaction of the CONSULTANT.
