Question 144: Ames- The mechanical equipment schedule on plan sheet M601 (Bldg. 25

Renovation Moffett Field) is missing the performance requirements for the mechanical equipment. Please provide a corrected plan sheet to include the missing data.

Answer 144: Please refer to sheet notes 1 and 2 on sheet M601 as follows: Sheet note 1 states

“Schedule provided for guidance to Contractor and for Contractor use. Provided schedules represent required design information to be provided by Contractor.” Sheet note 2 states “Refer to mechanical design criteria documents when specifying equipment”. The mechanical equipment schedule on sheet M601 is a template for the Contractor to use and represent the required design information to be provided by Contractor as part of a Design-Build contract/project. The mechanical design criteria shall be in accordance with the contract drawings and specifications.

Question 145: Ames-The specifications for Bldg. 25 omits the performance specifications for the

4,000 lbs. elevator. Please provide the missing specification.

Answer 145: The elevator is not part of the scope.

Question 146: Ames- The FP plans for Bldg. 25 doesn’t show the POC for the new fire sprinkler system. Furthermore, no site utility map is provided to show where water can be tapped for the new fire suppression system. Additionally, we were unable to locate flow test for the existing fire water loop. Please provide the above missing information.

Answer 146: The Point of Connection (POC) for the Fire Sprinkler System water source can be at the south west corner of Building 25. The most current hydrant flow test shows a 750 gpm flow rate and 50 psi water pressure at the nearest fire hydrant which is close by. The hydrant pipe size is 10” diameter. The preceding will be reflected in an amendment.

Question 147: Ames-The Project Requirements notes on drawing sheet M025-1800-G003 for the AMES Research Center task order indicated that the contractor shall be responsible for Final

Design and Final Permit Submission to NASA for review and approval. Upon reviewing the drawings and specifications it would appear that this task order is already 100% designed and approved for construction by the Moffett Field Permit Board. Please confirm that this project does not require design services of the contractor, except for any incidental engineering required for shop drawings or deferred design submittals? If the intent of the solicitation is to have the contractor be responsible for another designers 100% design documents as a design-build solicitation, this imposes a significant amount of risk to the contractor and contradicts any industry standard practices for Design-Build project delivery.

Answer 147: This project is considered as minimal design-build with areas in need to have the design submitted for final construction permits. The drawings to be provided are at the conceptual stage. As an example, even though the drawings show substantial completion for the seismic retrofits, the design would still need professional licensed engineer stamped calculations and drawings to verify the conceptual design and complete the details. For some portions of the work where only performance requirements are specified, the successful offeror is expected to provide actual design with design submittals to be permitted prior to construction.

Question 148: Ames-Drawing M025-1800-G101 Legend states, Option Priority item number relates to specific option bid item, and to reference drawing number M025-1800- G001 for priority list number. No option priority list is shown on this drawing M025-1800-G001, should this drawing be M025-1800-G000 for the Option Priority item number specific option bid item?

Answer 148: The reference drawing sheet shall be AM025-1800- G000 for priority list number.

The preceding will be reflected in an amendment.

Question 149: Ames- During the site walk the building was dark, we utilized our cell phone lights to observe the existing conditions. There were no lights in the building. We request another site walk to further assess the scope of work. Please consider scheduling another site visit.

Answer 149: No further site visit will be provided.

Question 150: Ames- Loads allowed on floor for high work. RFP states that ceiling work is to be completed in the auditorium area with high ceilings. We request that the government provide the allowable loads that can be placed on the flooring for use of equipment.

Answer 150: It is the Contractors' responsibility to determine the allowable load for equipment use during construction, with contractor to make determination through field verification.

Question 151: Ames-Attachment B, Additional Information/Item No. 2 - Identifies design to be stamped by a professional engineer in State of California. Please provide a list of items that are to be designed and stamped.

Answer 151: The solicitation package is a bridging document as an acceptable concept. The contractor is required to complete the design with drawings, specifications and calculations with sufficient details as a submittal for a construction permit from the Government in accordance with the California Building Code.

Question 152: Ames- We do not see specifications for design requirements, yet Plan Sheet G-

003 calls out for design submissions at 30%, 60%, 90% and 100%. Please clarify if this seed project is DBB or DB. If the project DBB, please provide complete structural design.

Answer 152: The project is a minimal design-build with the bridging document provided. Design is required for construction permit review in accordance with California Building Code.

Question 153: Ames- Sheet-002, LEED Certifications – Scope of work under the base bid and option do not provide complete reconstruction of the building. LEED cannot be achieved as specified under our scope of work. Please clarify the intent of LEED requirements.

Answer 153: This project, if with the full scope is implemented, shall achieve a minimum of

LEED-NC Silver as the goal. However, since the work on this project is phased due to incremental funding, it is therefore acknowledged by the Government that the current scope in implementation may not be sufficient to attain LEED Silver Certification. However, the Design-

Build Contractor is responsible for submitting and getting approval for the credits, as the intent is that the project will be certified at a later date when a tenant is identified and the needed tenant improvements are completed. The preceding will be reflected in an amendment.

Question 154: Ames- Sheet G002 Hazardous Material – Hazardous material required to be abated do not show quantities for abatement. Please provide quantities.

Answer 154: The Offeror is to estimate quantities based on drawings provided by the

Government.

Question 155: Ames- Sheet G-002 Hazardous Material - There is a disclaimer in the notes stating

“some testing has been completed on this project”. Are we to assume that a COMPLETE survey is to be completed by the contractor prior to start of demolition or are we to assume that this is a complete survey and no additional survey is required?

Answer 155: No additional survey is required by the Contractor. The Offeror is to use the survey reports for bidding purposes. The surveys provided for lead and asbestos should be considered complete for the interior of the building. The Government will provide additional survey of the building exterior and roof. Note that the Offeror must follow all requirements in the Project

Specifications.

Question 156: Ames- Sheet Various – Throughout the plans, there are statements that state

“remove and replace as necessary”. We are not able to complete a full survey of the project, we do not have any means of documenting quantities of work to be replaced. For each item that is identified as “removed and replace as necessary”, please provide quantities.

Answer 156: See response to Question 154.

Question 157: Ames- Sheet Various – Throughout the plans, there are statements that state

“Patch and Repair where water damage has occurred” on floors, walls and ceilings. We are not able to complete a full survey of the project, we do not have any means of documenting quantities of work to be replaced. How does a contractor quantify these areas? Please provide quantities for walls, ceiling, flooring and wood flooring to be repaired.

Answer 157: Water damage exists on the stage at the top of Stair S104, on the wall between the stage and Room 108, and the ceiling in Storage 215 and 216. Assume 42 SF of stage repair, 50

SF of ceiling repair, and 30 SF of wall repair.

Question 158: Ames- Sheet Architectural Various – Project plans do not contain window and door schedules. Please provide schedules.

Answer 158: Estimate in accordance with information already shown on the elevations views.

19.76’, and the invert elevations of the other manholes will need field survey. All of the preceding information to be reflected in an amendment.

Question 165: Ames-Building 25 Restoration (Ames Flight Research Center): Provide section detail of storm drainage system (including any drain tile/burrito drains) along the perimeter of the building.

Answer 165: Section detail is not available. No additional storm drainage exists beyond what is shown on drawings. Invert elevation at existing stone pit is ~27.5' and the stone pit bottom is

23.5’, approximately 5' and 9' below grade, respectively. The preceding information will be provided in an amendment.

Question 166: Ames- Note A7 on sheet AS101 states for the contractor to excavate the entire perimeter of the building, provide shoring along the entire perimeter, clean out all storm drain piping, and replace any sections that are damaged or beyond their usable life. The note then goes on to state the contractor shall reference the plumbing plans for more details. In review of the plumbing plans we see minimal storm drain work with most of the work associated with the installation of a new storm drain man hole. The plumbing plans

Answer 166: Question appears to be incomplete. Note A7 on Sheet AS101 only refers to excavation on the west side of the building to repair the existing storm drain. Note A15 on

Sheet AS101 states for the contractor to excavate the entire perimeter of the building to clean out the existing storm drain piping.

Question 167: Please reference sheet G000 and Attachment B for the following question. The base bid for Building 025 calls for the contractor to perform extensive demolition to the building and building systems.
