Q1A: Seed Project #2, in the layout plan identified in the CD which was given to us by your office IC7 is shown, but in the Single line diagram it is indicated as IC5. Which one is correct?

A1A: IC7 is the correct one.

Q1B: Seed Project #2, if the correct answer is IC5 then the control wiring and power diagrams are missing.

A1B: IC7 is new cubicle and not included in the project.

Q2: Seed Project #2, the control diagrams and drawings of M1 and M2 cubicles are not presented in the CD.

A2: There is no need for control diagrams to M1 and M2. M1 is not included in the project.

Q3: In order to transfer data from M2 cubicle to other cubicles what reference point on the bus bar should be used?

A3: The contractor shall provide manual transfer switch for bus selection and tie M2 Bus 1 PTs and M2 Bus 2 PTs via 2 amps three phase main circuit breakers. The output of the switch shall be tied with proper CBs to each protection relay (existing relay model number GE750). The manual transfer switch will be three phase and 25 amps.

Q4: The SF 1442 section 3.2.1 states that “PID and soil assessment expert(s) have a min of three (3) years factory training and certification”. Do you mean PID and soil assessment expert must have 3 years experience using PID equipment? (Is Person who has 3 years experience acceptable with experience documentation?)

A4: Yes, PID and soil assessment expert at the site shall have minimum of 3 years experience using PID equipment. Contractor shall submit either certification for his personnel or a certified test company for this action at the site.

Q5: The SF 1442 section 3.3.1 states that “Provides contents of a typical design submittal and describes methods and procedures to ensure each proposal contains a concise technical description, execution narrative and engineering calculations or other documents that supports the proposal for the project (e.g. Cooling and heating capacity calculation and lighting levels as required, etc.)”. The Seed Project #1 is Remove Abandoned UTSs, Bldg #5, #16, #997. There is not cooling and heating systems or lighting fixtures etc. under seed project # 1. Please clarify this evaluation factor.

A5: Contractor shall submit typical design and engineering calculations (if required) that describe he understood the project and requirements. This statement “Cooling and heating capacity calculation and lighting levels as required, etc” is just an example and does not show the expectations for this typical project design.
