Bid 627 New HVAC Modernizations at Oxnard High School & Pacifica High School (Both)

Bid Documents
The District intends to reject all bids on 10/14/2020
Additional access to sites has been scheduled for 7/24/2020 @ 9am at OHS, then to PHS

We are interested in submitting a bid as the prime contractor for the above referenced project, however we were unable to send a representative to the July 15 site visit. Can you please advise whether you anticipate that a second site visit might be scheduled?

The Mandatory Walk was on July 15th, “Mandatory”. Non-participant’s to the walk will not be permitted to bid this project. However there are multiple projects to follow over the next 3 months, with Adolfo Camarillo presently bidding but not yet walked.

Project Specification 23 09 00 states “Carrier OPEN BACnet Controls” as only Acceptable Manufacturer. Next Level EMS would like to propose “Siemens” BACnet, as alternate Open Controls for competitive bidding on the project. Attached is an overview and some technical details for the non-proprietary BACnet Siemens HVAC Controls System. Please confirm if Siemens is an acceptable manufacturer. REFERENCE: 23 09 00 Direct DIGITAL Control System

Cost Impact: Yes

Schedule Impact: Yes

Product is not sustainable or compatible to existing systems without adaptations. The use of the product would create a huge cost burden and hardship on the district as an example redesign, additional training, additional staff, programming, monthly and service impacts. (Hardship) As previously responded this product is not acceptable alternative to the immediate projects design.

Re Fire Alarm system and the GUI/graphics annunciator: Does the District prefer to use a wall based LED display like those created by H.R. Kirkland, or would they like to have a computer based work station that shows the location of the alarm in its respective building?

None at this time.

Fire Alarm / Conduit – On Pacifica Sheet FA0.2 note 6, mentions pulling new fire alarm wire through (2) 2″ conduits routed through existing site boxes. At the job walk, we didn’t see these 2″ underground conduits or existing site boxes and the routing isn’t shown on the fire alarm site plan. Please provide the routing for the new fire alarm wires linking the buildings, and clarify if new trenching, conduits, and site pull boxes will be required?

Pull existing Fire Alarm wires/cables from (E) conduits. Reinstall the (E) with (N) FA wires/cables into the (E) conduits. Refer to addendum for more information.

Re Fire Alarm system and the GUI/graphics annunciator: Does the District prefer to use a wall based LED display like those created by H.R. Kirkland, or would they like to have a computer based work station that shows the location of the alarm in its respective building?

IMEG recommends Silent Knight 6860 Annunciator in lieu of GUI type annunciator or computer based work station.

Spec section 22 05 00-1.4 in both spec. books lists coordination drawings and requirements for MEP trades to avoid conflicts. Are coordination drawings required for this project? If so, who is responsible for locating and drawing the existing systems that will interfere with the work and are not scheduled to be replaced or removed (i.e. fire sprinkler piping)?

Division of work is at the responsibility of the general contractor.

Are secondary condensate drain lines and or secondary drain pans required for the new mechanical equipment?

Will be addressed in Addendum 1.

During the initial job walk it was noticed that there are many existing interior block walls at both campuses that may not be shown or called out on the drawings. Can a wall legend please be provided that shows the types of walls and if fire rated or not?

A wall type color legend has been included within this response for both campuses. Refer to Architectural response.

Pacifica High School drawing MPD2.2 shows a drywell near grid line K-4 with a note about offsetting condensate but there are no condensate lines shown to be ran there. Please advise if this an error.

Drywall and note will be removed in Addendum 1.

Please clarify, do I need to acknowledge addenda before the bid electronically emaiol address to you or acknowledge the addenda included during electronic bid package submittal?

The addenda should be signed individually and acknowledged on the Bid Form then submitted with the bid package by the bid due date and time. The bid is due electronically with the exception of the bid bond/security, which is due in hard copy by the bid due date and time (and a copy submitted with the bid package).

Will the project still be awarded as one contract? Or will it be up to the District on how to award?

The project will be awarded as one contract.

REF: Mechanical Equipment Connection Schedule Bldg E on PHS-EE2.2- Addendum #3 Attachment C does not appear to be updated to reflect the changes made in PHS-MP0.3 Attachment C and PHS-MPE2.0 dated 06/08/2020. Please confirm if updated Electrical drawings will be issued to match changes made in addendum #3 Mechanical?

 Updated Electrical drawings issued under Bid Clarification Addendum #3 matches with Mechanical sheets. Please refer to Electrical sheets ED 2.2, ED 2.3, ED 3.2, EE 2.2 which is also attached in this RFI response.

On the second job walk for this project , could you please send me sign in sheet .

There wasn’t a sign in sheet for the second job walk because it was not mandatory and was offered only to those that attended the first one (to bring their subcontractors if needed).

I was looking through the bid documents for the Oxnard & Pacifica HS project and the Adolfo Camarillo HS project. I see that the C-Class subs need to be prequalified with the district, but I didn’t see a deadline for the prequalification. Can you let me know what that would be for both projects so we know what subs we can use for our bid?

The bid deadline is also the deadline for prequalification.

REV #1: See attached email from the Schneider Square D distributor on following page stating that factories do not offer the marine coating listed below. Electrical equipment is offered in NEMA 4X (Stainless or fiberglass) for these conditions. No electricians bidding to us are ‘certified applicators’ of this coating, thus they cannot apply it. This will likely result in electrical proposals excluding this coating or adding a significantly higher price to outsource it. Addendum 3/Arch Addm 1 Electrical drawings now contains a new general note #3 that reads: Coatings: Apply marine coating by certified licensed applicator. The coating product manufacturer shall be able to document a class 5B result on a cross hatch adhesion test (ASTM D5339) and the testing for a minimum of 4000 hours in both salt spray (ASTM B117) and acid salt spray (ASTM G85) test. The total dry film thickness of the coating shall be 1Mil. The coating shall provide inherent protection against ultraviolet radiation and have a dry temperature resistance from -4* F to 302*F. The following components shall be coated: Electrical disconnect switch, J-Box’s and panelboards mounted in roof. Note: This same requirement is listed in both OHS & PHS spec section 23 74 11 part 2.14 for condenser coils, evaporator coils, and cabinets for package and split system HVAC units. These requirements are not listed in the painting section 09 90 00. 1. Electrical suppliers are not familiar with this coating being offered as a factory finish, will NEMA 4X satisfy the requirements? 2. If this marine coating is not offered as a factory finish, yet requires a certified licensed applicator, shouldn’t this be part of the painting specifications?

After reviewing pictures of 20+ year old, existing, roof mounted disconnects, they appear to be in fair condition. Therefore, Nema 3R is acceptable in lieu of Marine Grade Coating.

I am trying to confirm, from the Instructions to Bidders, if the Bid Bond must be delivered to the District as an original prior to the bid deadline. I did not find any specifics on whether or not that is required.

Per the Notice to Bidders (which has bid due date change via addendum of course):

I wasn’t able to find how the bids will be opened for the Oxnard & Pacifica bid on Thursday. Is there a zoom meeting we need to attend or will an email be sent out?

The will be opened after the bid due date and time and results will be posted online. There is not an in-person or video bid opening. When bids are emailed to me, I will reply with a “received” response.
