SUMMARY OF CHANGES

1. The Task Order Announcement is amended to include the attached completed sign-in sheet from the site visit that took place on June 03, 2020.

2. The Pre-Proposal Inquiries and Responses are listed below:

PPI 009

DWG C1-Note 5-Pg 3/26: Sanitary Sewer POC: Is the intent to connect the new sewer service to the existing SSCO (installed with the FRC MAT building)? Or does the new sewer service need to connect to the existing manhole?

Answer: Yes, the intended POC for the sewer is at the location of the indicated cleanout whether or not the cleanout currently exists. Keynote 6 points to the approximate location of the sewer per the FRC RFP plans, and the adjacent line showing the cleanout references the approximate location shown on the FRC as-built plans. Connection to the manhole is not specifically required. Contractor shall determine appropriate connection point. Refer also to Section 01800 - 1.4.8.

PPI 010

DWG C1- Pg3/26: Sanitary Sewer: The existing 6-inch sewer line is laid relatively flat (under 1.0%), has the capacity of the existing line been checked for the additional sewer flows? Will the downstream piping need to be upgraded to accommodate the additional sewer flows?

Answer: For bidding purposes, the contractor shall assume the downstream pipe will accommodate the additional sewer flows from the OPC MWD Facility. Post award, the contractor shall verify sewer flows, and the downstream pipe capacity, and report the information to the COR.

For information, refer to Study Sewer System and Recalculate Plant Replacement Value (PRV) at USCG Base Los Angeles / Long Beach San Pedro, CA, HSCG88-15-J-PQQ105 dated August 19, 2016 attached to this Addendum. Note that this sewer study was conducted prior to the FRC Homeport LA/LB Project. FRC Homeport LA/LB as-built documentation was provided in Amendment 01.

PPI 011

DWG C1-Pg 3/26: Sanitary Sewer: Are as-built drawings and calculations available for the onsite gravity and wharf force main sewer systems?

Answer: Refer to Amendment 01 PPI 001 and PPI responses in this amendment for available as-built drawings.

Refer also to "Landside Site Investigation FRC Homeport Buildout At USCG Base Los Angeles/Long beach - San Pedro, CA Final Submittal USCG Contract No. HSCG50-15-J- ADM064, USCG Project No. 5930715" dated January 2016. Note that the "Landside Site Investigation" was conducted prior to the completion of the FRC Homeport LA/LB project. No other calculations are available.

PPI 012

DWG C1-Pg 3/26: Sanitary Sewer: The existing wharf sewer is serviced by a force main. Have the SSFM pumps been upgraded as noted in the EI?

Answer: The Coast Guard is unclear what the term "EI" refers to. The lift station pumps were upgraded as part of the Homeport FRC LA/LB project. Refer Homeport As-Built drawings provided in amendment 001, Drawing Number C532, Sheet 23 of 148.

PPI 013

DWG C1- Note6 - Pg 3/26: Water: Is this POC for potable water or fire water? Where is the other water POC? Where will be water meter and backflow be located? There doesn’t appear to be room at the POC shown. Where will the BFD be located for the fire water connection? Again, there doesn’t appear to be enough room at the POC shown. Will the water building connection points need to be relocated?

Answer: Key Note 6 indicates the approximate potable water connection point for the OPC MWD Building potable water from the existing water main stub in this area. Water main stub shall also be connected to the waterline reroute noted as Key Note 8. Contractor shall determine appropriate configuration and locations for piping, valves, meters and backflow prevention devices. Contractor shall determine if existing water main stub requires modification, and shall provide all work to connect the OPC MWD Building potable water service, and water line rerouted to clear new building footprint.

Refer to Section 01800-1.10.2 for Fire Protection Sprinkling Systems, and Section

01800.10.2.1.6.1 for additional information regarding OPC MWD Building Fire Protection Sprinkler System water supply.

PPI 014

DWG C1- Pg 3/26: Gas: The existing 2-inch gas service line for the FRC MAT building was connected to the 4-inch gas main in Seaside Ave. Where is the proposed gas POC for the new building? Does the new building require a separate connection to the main in Seaside? This will involve offsite work.

Answer: The contractor shall connect the gas service to the two-inch service near the FRC Building, and does not require a separate connection to the gas main in Seaside Avenue.

PPI 015

DWG C1- Pg 3/26: Storm Drain: The project requires Stormwater Protection measures including LID for the new improvements. Does the installation have an existing MS4 permit? Are there any site-specific stormwater measures required? Are there available as-built drawings and drainage reports for the existing storm drain system?

Answer: Base LA/LB does not have an existing MS4 permit. For site specific stormwater measures, contact the appropriate region of the California Water Board. No as-builts exist for the current stormwater drainage system, however some information is available in the "Landside Site Investigation FRC Homeport Buildout" provided in this amendment.

PPI 016

DWG WS6- 15' x 200' floating dock is called out. Confirm that this is not included in the scope of work.

Answer: Confirmed, as noted in amendment 003, PPI 003: "The FRC Floating Docks are existing to be protected, to remain in-place, and fully operational thoroughout the construction duration."

Answer: Please see the enclosed as-built information for the WHEC pier.

PPI 018

DWG C4- Provide as-built information that depict the erosion extent noted in the drawings. It is not clear how much of the detail shown in 1/C4 needs to be reinstated back.

Answer: As-built information of this area is not available. Refer to Amendment 003 PPI 003.’

PPI 019

DWG WS1- Repair of raprap is noted between bents 20 and 21. (1) Does the rock slope need to be designed or can this simply follow the provided details of the existing slope? (2) Are there any other locations that require repair to the riprap?

Answer: Refer to Response to Amendment 003 PPI 003. Design shall be as noted on DWG C4, and Section 01800-1.4.12. The repair area shown on WS1 refers to Civil Drawings, and is indicated on DWG C4.

PPI 020

DWG WS1- New (125 ton) mooring bollards are specified on the existing structure. Is the the bidder to assume that the existing deck is able to withstand the rated load (implied in Section 01800-1.8, page 4 of 8, Paragraph on "Existing WHEC Wharf")? i.e. is there a need to assess the concrete deck and track the load to the piles as a result of the new rated bollard installation?

Answer: The bidders may assume the existing wharf pile cap regions are adequate to transmit the bollard anchorage loads as long as the the anchor bolt capacity is fully developed and the existing reinforcement is not damaged during installation.

PPI 021

Pile Driving: Are there any concerns for any unexploded ordnance (UXO) in the new wharf piling area? If so, is there a need to have UXO surveys done prior to pile installation?

Answer: The Coast Guard is not aware of any UXO concerns in the area of the new wharf extension.

PPI 022

01800 1.8, pg 4/8: The RFP states "The designer may also use the recently developed publication ASCE/CORPRI Standard 61-14 “Seismic Design of Piers & Wharfs” for their seismic design approach for the new wharf extension". Please clarify that if ASCE 61-14 is used, what is the design classification to be used for the structure (high, moderate or low)?

Answer: The Design Classification shall be "Moderate" if ASCE 61-14 is used for seismic design. It is a goal of the USCG that the level of seismic damage shall be "controlled and repairable" after a significant event.

PPI 023

01800 1.8.3.2, pg 3/8: A 100-Ton Mobile Crane is specified for the new wharf extension. What is the maximum outrigger load?

PPI 024

01802 2.7.2.4 Pg 13/15: The RFP design indicates to ensure LEED requirements are incorporated. Which level of LEED criteria are required? For example, water savings has different levels of savings that can be achieved through LEED (10%, 20%, 30%, etc.). Is the intent to meet Minimum LEED criteria?

Answer: See Section 1800-1.3.2 for LEED requirements: "The new MWD facility shall be certified by the US Green Building Council (USGBC) LEED-NC at least at the minimum level of "Certified" utilizing the LEED for New Construction (LEED-NC) Green Building Rating System." Specific to the water savings requirement, see section 1800-1.3.2.4.(a)

PPI 025

1800-1.10.1.1.5: Will need definition of Public/Common vs other areas for the purpose of Notification Appliances. Suggest defining non-Public/Common areas as those with greater than 5 occupants.

Answer: Anything with an occupant load exceeding 1 such as janitor's closets or private office is to be considered as public/Common.

PPI 026

1800-1.10.1.1.6: The Circuit requirements (Class A, separation, isolation modules, etc.) appear excessive for the building risk profile, and current addressable system technology. Would the government be interested in going with Class B circuits as a value engineering approach?

Answer: The existing building As-Built drawings indicate that the system is installed as Class "A" cabling, The system extension shall also be installed as Class "A" cabling.

PPI 027

1800-1.10.1.1.6: Will the intent be to provide Mass Notification for the new Buildings per current UFC requirements?

Answer: The MWD Building fire alarm system is to be an extension of the existing FRC MAT building per RFP 1.10.1.1.5. For Mass Notification requirements, including relevant criteria, see RFP 1.10.1.1.8.

PPI 028

1800-1.10.2.3: Will contractor be responsible for conducting another flow test to validate current provided information? If so, please provide the logistics to coordinate for performing such a test.

Answer: Yes, per RFP 1800-1.4.7, an updated hydrant flow test is required. Contractor is responsible for contacting the Water utility company for requirements. Base LA/LB does not have any special requirements other than to coordinate the date and location of the fire flow test with Facility Engineering Staff.

PPI 029

1800-10.2.5: Will the sprinkler system be expected to be seismically protected beyond the requirements of NFPA 13?

Answer: Seismic bracing will be accordance with ASCE 7, which defaults to NFPA 13 unless the CBC requirements exceed NFPA 13.

PPI 030

01800-1.8.2: Specification Section 01800 (as well as the geotechnical report) reference the 2015 International Building Code (IBC) and the standards ASCE 7-10. However, the Unified Facilities Criteria (UFC) 1-200-01 (DOD Building Code, dated October 8, 2019) adopted the newer edition of the IBC (2018 IBC), which in turns utilizes ASCE 7-16. For reference, the latest editions of California Building Code (CBC) also uses IBC 2018 and ASCE 7-16. There are significant differences in seismic design requirements between the two codes. Please confirm which code (IBC 2018 & ASCE 7-16 or IBC 2015 & ASCE 7-10 should be adopted for this project.

Answer: IBC 2015 and ASCE 7-10 shall be used. Note that UFC 1-200-01 is not referenced in the RFP and is not applicable to this project.
