OWNER.

1.10 OWNER FACILITIES

A. Operation and Shutdown of Existing Facilities:

Project Management and Coordination 01 31 00-8

B. Thoroughly check immediate and adjacent areas subject to excavation by visual examination (and by electronic metal and pipe detection equipment, as necessary) for indications of subsurface structures and Underground Facilities.

C. Make exploratory excavations where existing Underground Facilities or structures may potentially conflict with proposed Underground Facilities or structures. Conduct exploratory excavations in presence of ENGINEER and sufficiently ahead of construction to avoid possible delays to CONTRACTOR’s Work.

1.12 REFERENCE POINTS AND SURVEYS

A. Location and elevation of bench marks are shown on Drawings.

B. Dimensions for lines and elevations for grades of structures, appurtenances, and utilities are indicated on Drawings, together with other pertinent information required for laying out Work.

3. Notify ENGINEER at least 3 working days in advance of time when grade and line to be provided by others will be needed.

4. Check and establish exact location of existing facilities prior to demolition work and any connections thereto.

5. In event of discrepancy in data or staking provided by ENGINEER, request clarification before proceeding with Work.

6. Preserve and leave undisturbed control staking until ENGINEER has completed checks it deems necessary.

7. Re-establish reference points resulting from destruction by CONTRACTOR’s operations.

8. Retain professional land surveyor or civil engineer registered in state of Project who shall perform or supervise engineering surveying necessary for additional construction staking and layout.

10. On request of ENGINEER, submit documentation.

11. Provide competent employee(s), tools, stakes, and other equipment and materials as ENGINEER may require to:

a. Establish control points, lines, and easement boundaries.

b. Check layout, survey, and measurement Work performed by others.

c. Measure quantities for payment purposes.

d. Assist OWNER’s staff during bypassing or other interruption of normal operation.

12. Cooperate with ENGINEER so that checking and measuring may be accomplished with least interference to CONTRACTOR’s operations.

3. Daily construction reports.

4. Field condition reports.

1.2 DEFINITIONS

F. Activity: A discrete part of a project that can be identified for planning, scheduling, monitoring, and controlling the construction project. Activities included in a construction schedule consume time and resources.

2. Predecessor Activity: An activity that precedes another activity in the network.

3. Successor Activity: An activity that follows another activity in the network.

G. Critical Path: The longest connected chain of interdependent activities through the network schedule that establishes the minimum overall Project duration and contains no float.

H. Float: The measure of leeway in starting and completing an activity.

1. Float time belongs to OWNER.

1.3 SUBMITTALS

I. Submittals Schedule: Submit three copies of schedule. Arrange the following information in a tabular format:
