ITEM NO. 4 SCOPE OF WORK The following additions, comments and/or clarifications to the Scope of Work for this project as shown within the project documents are to be reviewed and incorporated in the Bidder s bid submission as applicable or relevant. Item 4a: RESPONSES TO CONTRACTOR QUESTIONS (continued from ADDENDUM 2) Q. MV cables are 5KV at 133% and 8KV at 100%-Paragraph "F" Conductor Insulation- EPR section shows 220Mil and that s 15KV. Which MV cable is acceptable to West LA College requirements and existing 4" conduit runs through campus? A. Provide the 5kV 133%/8kV 100% Insulation Cable with standard mil thickness insulation. Page 2

3 Item 4a (cont.): RESPONSES TO CONTRACTOR QUESTIONS (continued from ADDENDUM 2) Q. Really looking for the pictures of Electrical equipment and Manholes on West LA College to help with bid process in terminations and racking and grounding already in manholes to what is shown on prints. Will they be inserted by addendum today? Load interrupter switches-(t-1) -(T-2)-(T-XX)-(T-3)-(T-4)-(T-6)-(T-7) Transformers requested-(t-1) -(T-2)-(T-XX)-(T-3)-(T-4)-(T-8)-(T-9)-(T-10) only (T-6 & T-7 secondary since xfmr s and LI switches will be replaced also-new Pad?) Manholes requested And vaults under transformers for T-8 and T-9 A. All manhole and transformer pictures that our office has, have been uploaded. (SEE PREVIOUS ADDENDUM) Q. Specification B refers to a 20-year warranty on terminations. Our supplier was unable to confirm that this warranty is available from any of the listed manufacturers. Which manufacturer(s)/products will provide this warranty? A. Provide a minimum 1 year warranty. Q. Specification F indicates 8kv -133% rated cable with 220 mil insulation. This is nonstandard. 220 mil is generally used for 15kv-133% rating. 8kv -133% is 140 mil insulation, but this is not a stock size and would require special order with long lead times. Cable rated 5Kv-133% / 8kv-100% with 115mil insulation is generally available from the listed manufacturers. Will 115mil insulation be acceptable? A. See above question/response. Q. Manhole details appear to indicate spare ducts. Can these be utilized to pull new cable before removing old cable if accurately recorded on record drawings? A. If spare conduit is available, the Contractor may use it. Contractor is responsible to remove the existing cable to allow existing utilized conduit to be spare. Q. Drawing E141- MH-12 and 16 indicate symbol for existing modular splice (dead break). However on E142 note 6 is indicated for the splices at MH-12 & 16, which indicates to replace taped splice. Which is existing at MH-16, modular splices or tapped splice? A. Provide new modular splice. Page 3

4 Item 4a (cont.): RESPONSES TO CONTRACTOR QUESTIONS (continued from ADDENDUM 2) Q. E142 note 4 at MH 7 indicates to remove existing hand splices and pull new conductors through. However the new conductor start at MH-7. Should this be to splice new conductors to existing conductors from MH100? A. At Vaults MH-17 and 19, delete note 4 and splice indicated. Cable is intended to be new and pulled straight through. Q. Existing Load Interrupter switches will be eliminated at T6 & T7. Should padmount enclosures be utilized over the existing conduits at these locations? A. (Addressed in Addenda #2) - These have been added to the Feeder Schedule on Sheet E142. Q. Manhole details appear to indicate spare ducts. Can these be utilized to pull new cable before removing old cable if accurately recorded on record drawings? A. If spare conduit is available, the Contractor may use it. Contractor is responsible to remove and properly dispose of the existing cable as may be required to allow existing utilized conduit to be spare. Q. Drawing E141- MH-12 and 16 indicate symbol for existing modular splice (dead break). However on E142 note 6 is indicated for the splices at MH-12 & 16, which indicates to replace taped splice. Which is existing at MH-16, modular splices or tapped splice? A. Provide new modular splice. Q. E142 note 4 at MH 7 indicates to remove existing hand splices and pull new conductors through. However the new conductor start at MH-7. Should this be to splice new conductors to existing conductors from MH100? A. At Vaults MH-17 and 19, delete note 4 and splice indicated. Cable is intended to be new and pulled straight through. Q. Existing Load Interrupter switches will be eliminated at T6 & T7. Should pad mount enclosures be utilized over the existing conduits at these locations? A. (Addressed in Addenda #2) - These have been added to the Feeder Schedule on Sheet E142. Q para 2.6 E indicates to provide neon voltage indicators on each splice above grade. It appears from the drawings that that all of the splices will be below grade in the manholes. Are there any locations that the voltage indicators will be required? A. Voltage indicators are not required. Page 4

5 Item 4a (cont.): RESPONSES TO CONTRACTOR QUESTIONS (continued from ADDENDUM 2) Q. Specification refers to only 600A dead break terminations and junction modules. A) Drawing E515 Detail 2 indicates splices with 600A modular connections with connecting plugs. Can the connecting plugs be utilized for multi-way (3-4) splices? B) Specification k indicates bushing wells inserts, which is only compatible with 200A elbows. Will 200A load break elbows be acceptable at the transformers provide conductor sizes are compatible? A. Connecting plugs can be used for 3-4 way splices. 200A elbows are acceptable at the transformers. Item 4b: RESPONSES TO CONTRACTOR QUESTIONS (ASKED OF EOR ANSWERED BY LACCD PM) Q. Bid form we did not find a bid form or schedule of values included in the bid envelope provided. Will these be provided with the addendum 1 referenced in of the instruction to bidders. Will this also include the Contractor Qualification Statement and sample contract form reference in the instruction to bidders? When will this addendum be issued? A. * See bid form attached to with this ADDENDUM 3 * See information above in Item 3.2 * The Sample Contract will be included FOR INFORMATION ONLY and will be transmitted via separate cover on 10/09/17. Q. Instruction to bidders indicates a contract time of 120 days from NTP. Based upon discussions with transformer manufacturers and previous experience 120 days may not adequate to obtain submittals, approval, procure and install the new transformers. Will a longer contract duration be considered? A. LACCD will certainly consider the issue of a NO COST contract extension to the stated contract time based on all factors (schedule, market factors, etc.) relevant at the time of award to the successful bidder. Q. Will a laydown/staging area be provided on campus for the project? A. Yes, this and all other logistical questions will be discussed and mutually agreed to at the Pre- Construction Conference to be scheduled after Project Award and prior to the start of the job. Q. Please clarify the working hours for the project and any special requirements for power shutdowns for cable and transformer replacement including temporary power requirements. A. As discussed in the Pre-Bid Conference, standard campus work hours will be 8AM 6PM Monday through Friday. Saturday hours will be available from 8AM 6PM with minimal advance notice only. (cont.)
