A Preliminary Design Document will detail the following: • Process Design Criteria. • Opinion of Probable Construction Costs. • Equipment Data Sheets and Manufacturer Information. • Specification Outline. • Piping Schedule. • Construction Sequencing. • Control Descriptions "Draft" Specifications. • Major Equipment "Draft" Specifications. • Motorized Valve and Gate "Draft" Schedules The Equipment Data Sheets and Manufacturer Information section will provide information on the major items of process equipment selected for the plant based on Garver's experience and Owner preference. Equipment data sheets that summarize operating conditions and key components will be provided along with manufacturer catalog information. Garver will lead and participate in a Preliminary Design Workshop. The workshop will be held at the Owner's location and major items of discussion will include: • Review and refinement of process design criteria. • Review and refinement of preliminary P&IDs and preliminary selection of instrumentation. • Review and refinement of preliminary electrical one -line drawings. • Review and refinement of preliminary SCADA design approach and system architecture. • Review and refinement of the preliminary site plan, hydraulic profile, and facilities layouts. • Review and preliminary selection of major equipment items. • Review of proposed construction sequencing. • Process Control and SCADA workshop module. • Preliminary Design Phase OPCC As part of the Preliminary Design Workshop, Garver will conduct an O&M focused discussion to determine process control parameters and equipment preferences. The WWTP staff preferences will be documented within the preliminary design documents. The O&M discussion and SCADA integration discussions will be a component module of the Preliminary Design Workshop in this scope of work. Garver will prepare copies of the Preliminary Design Submittal (both hard and pdf electronic files) and submit for review by Owner. Garver anticipates two weeks for Owner review and comment time once the Preliminary Design submittal is delivered. Garver will prepare and transmit a written documentation of "mutually agreed to" responses to the Owner's review comments of the Preliminary Design Documents. As part of the Preliminary Design Phase, Garver will: • Coordinate with TCEQ via telephone on project status and design criteria. • Submit the Preliminary Design Report to TCEQ for review. • Coordinate with the Owner's input, any responses to TCEQ review comments. Preliminary Design Deliverables shall be: • Two (2) hard copies of the draft Preliminary Design Documents (including half size drawings) • Two (2) hard copies of the draft of the Preliminary Design Report. • Two (2) hard copies of the final version of the Preliminary Design Report. • Required copies for Funding and Technical Review as required by State Agencies. 5.
