Clarlflcation on the 1CS system:
Attachment A to Request No. KS12007
Queatlon: Is it the intent that the Integrated Control System modifications be performed in-house by
PEF or other contracted entities?
Answer: PEF will perform ICs modifications.
ClarificatiodComment to Equipment Specification and Design Specification definition:
Question: The terms Equipment Specification and Design Specification appear to be interchangeable.
Are these reference terms the same in the PEF system? Please clarify if they are not the same.
Answer: Design Specifications are the requirements for the component or system parameters provided in
an engineering document. Equipment Specifications are the PEF Engineering Documents that are used
to order equipment in accordance with EGR-NGGC-0020. Note 4 has the issuance of Equipment
Specifications developed per NGGC-EGR-0020 also requires generation of an EC per EGR-NGGC -0005
CIarificationlComment on the Reference to Affected Calculations:
0
Question: Section 1.9.14 references more than 5 calculation documents out of the -1500 calculations
that will need to be revised or evaluated. Are these other affected documents to be included in the
respective EC package preparation, or are the critical documents determined to be the 5 identified in the
RF P with any other documents to the scope to be defined later?
Answer: Additional calculations not identified within the RFP should be identified and may be bid as part
of a fixed price proposal or identified that they will be addressed separately as T&M.
ClarificationlComments on the schedule:
Questlon: A brief review of the schedule noted that there are a number of instances where items are to
be completed prior to a predecessor task being completed, or, not enough time has been allotted for the
task based on a projected authorization date. A couple of examples include: the reference to the PEPSE
model being completed by 9-20-07 when a typical PEPSE analysis and documentation takes 8 weeks to
complete after the receipt of the turbine thermal kit. As mentioned previously, the turbine building
structural evaluation is scheduled to be completed prior to the completion of the ordering and ECs for
turbine items, MSRs, etc. Please clarify.
Answer: A completed PEPSE Analysis was requested by the TG Vendor in order to perform the Thermal
Kit Analysis. Subsequent conversations have identified that a completed PEPSE run is not required.
However, the data sheet in the RFP shows what data will be required by the end of Sept to support the
LP and HP turbine rotor designs, The weights of replacement components are readily available and can
be provided for the Structural evaluation in order to meet desired schedule.
