CLARIFICATIONS: (1) QUESTION: I wanted to clarify – will the owner (i.e. BCPS) be hiring an

independent inspection agency for structural steel testing, concrete testing, soils testing etc. at Lansdowne Elementary School or will that fall under the general contractor?

RESPONSE: BCPS will independently select and hire a testing agency.

(2) QUESTION: Assuming the former, will your team issue a separate RFP for

testing & inspection services?

RESPONSE: A separate RFP for testing services will not be generated for this project.

(3) CLARIFICATION: While reviewing the specifications for this Project, I noted what I

believe to be errors, and one omission.

On Pgs. 763-764 of Spec Volume II, the following is inconsistent with the current BCPS system. The sections are:

2.5 Software 2.6 Video Network Server and Network Video Recorder 2.7 Video Network Switch

Also typically included under one of the Security subsections is a statement that this work must be performed by one of the current BCPS on call security Contractors. It appears this statement was omitted. I have included as an attachment the list of current on call Vendors.

RESPONSE: Refer to updated Video Surveillance Spec section 282300 issued as part of this addendum for software and switch requirements. Provide one (1) Interlogix TruVision TVN-2132-P-16T network video recorder.

(4) CLARIFICATION: There is no indications on any of the prints to cover the parking lot

lights with locations and and types?

RESPONSE: The General Contractor shall be pre-qualified BCDPW Classification “I”, BUILDINGS, Category 1, New Building Construction. Demolition sub-contractors shall be pre-qualified Classification “I” BUILDINGS, Category 7, DEMOLITION.

(96) CLARIFICATION: We noted that the subject project has come back out for bid. But it is again listed as requiring certification in category 1-New Building Construction and category 7-Demolition. As we explained before, a General Contractor would not be qualified under the demolition code, and would subcontract that work to a qualified demolition contractor. Likewise, a demolition contractor could not build a new school. Please confirm that BCPS intends to keep these requirements. We believe this will severely limit competition on this project. A suggestion would be to require the demolition subcontractor to be qualified under category 7 by BCPS.

RESPONSE: The General Contractor shall be pre-qualified BCDPW Classification “I”, BUILDINGS, Category 1, New Building Construction. Demolition sub-contractors shall be pre-qualified Classification “I” BUILDINGS, Category 7, DEMOLITION.

(97) QUESTION: Will BCPS hire the agency to provide the construction testing and inspection services for the referenced project or will that be the responsibility of the general contractor?

RESPONSE: BCPS will hire an independent agency for construction testing and inspection services.

(98) QUESTION: I wanted to submit a formal question in regards to the bid date for

Victory Villa and Lansdowne Elementary. With the addendum that was issued for Victory Villa yesterday they are both now bidding on 12/15 at 1pm and 2pm. With these being due on the same day it is going to be very difficult for us to bid both projects and I’m sure it will be difficult for the other GC’s as well. Was your intention to have both projects bidding on the same day? We have never really seen this done especially by the same

owner. We feel that Lansdowne should now be pushed a week in order to have enough time to properly review everything and to allow us to submit bids for both projects.

RESPONSE: The bid date for Lansdowne Elementary School will remain. The bid date for Victory Villa Elementary School will be revised.

(99) QUESTION: Note Victory Villa’s bid date has been changed to December 15, 2016. Please advise if you plan on changing Lansdowne’s Bid Date.

RESPONSE: The bid date for Lansdowne Elementary School will remain.

The bid date for Victory Villa Elementary School will be revised.

(100) QUESTION: Will BCPS be moving the bid due date back due to the fact that Victory Villa, a project of similar size and scope, will be bidding at the same time now as Landsdowne?

RESPONSE: The bid date for Lansdowne Elementary School will remain.

The bid date for Victory Villa Elementary School will be revised.

(101) CLARIFICATION: Note Victory Villa’s bid date has been changed to December 15, 2016. Please advise if you plan on changing Lansdowne’s Bid Date.

RESPONSE: Lansdowne Elementary School’s bid date will remain. Victory

Villa Elementary School’s bid date will be revised. (102) QUESTION: Who is responsible for providing independent testing/inspection

services (steel, concrete, compaction, etc.), BCPS or the contractor?

RESPONSE: BCPS is responsible for providing independent testing/inspection services (steel, concrete, compaction, etc.)

(103) QUESTION: Who is responsible for providing commissioning agent services, BCPS or the contractor?

RESPONSE: Commissioning agent services are not in the contractor’s scope of work.

(104) CLARIFICATION: Please confirm that the completion date for the new building is August of 2018 and the existing building demolition along with the associated site work is to follow the phasing plan shown on Drawings C0.4B.

RESPONSE: The completion date for the new building is August of 2018. The existing building demolition and its associated site work will follow the phasing plan shown on Drawing sheet C0.4B.

(105) QUESTION: I just left you a voicemail, but wanted to follow up here. My firm,

Engineering Consulting Services (ECS), would like to provide pricing for structural steel testing, concrete testing, soils testing

etc. for the new Lansdowne Elementary School project. I understand that Baltimore County Public Schools will be hiring for those services directly, but I haven’t seen anything come out on eMaryland Marketplace requesting pricing. Will you be sending out a separate RFP at a later date? Any insight you can offer would be greatly appreciated!

RESPONSE: A separate RFP for testing services will not be generated for this project. BCPS will independently select and hire a testing agency.

(106) QUESTION: Can the AISC Certification for Steel Fabricators and erectors be

waived? This limits sub-contractors from pricing the project.

RESPONSE: For Fabricator who are not AISC, refer to specification section 05 12 00 – 1.4E.3. Steel Erectors need to be AISC certified per specification.

(107) QUESTION: Who pays for the building permit? In Supplemental Condition

008000-1 it calls out that the Owner pays for the building permit and we are in charge of the rest. But in Spec section 008900 Permits, applications and fees it states the Contractor is to pay for all permits.

RESPONSE: The Owner will pay for the building permit. Any other required permits, applications or fees will be the responsibility of the Contractor.

(108) QUESTION: Will there be a site Visit?

RESPONSE: Site visits are to be arranged and coordinated with the Building Operations Supervisor. Visits may occur before 8:00 AM or after 4:00 PM.

(109) QUESTION: Will BCPS issue a bid form for the construction testing and

inspection services or should the testing agencies submit their own bid form/proposal?

RESPONSE: BCPS will not issue a bid form for the construction testing and inspecting services. BCPS will hire an independent inspection and testing agency for this project.

(110) QUESTION: Will there be a walk-thru/site visit at Lansdowne ES?

RESPONSE: Site visits are to be arranged and coordinated with the Building Operations Supervisor. Visits may occur before 8:00 AM or after 4:00 PM.

CLARIFICATION: Section 00400: FORM OF PROPOSAL paragraph 2.4 Unit

Price has been reduced from 59 to 37 line items. A corrected page 7 of 20 from the specification solicitation and a corrected pages 7 & 8 of 10 form the 00400 Form of Proposal – Price Proposal [excerpt] are attached for your submission.
