20%.

- We would like to request informa�on on Sec�on B - Supplies or Services & Prices on Costs Op�on Line Item 0002 En�re work complete for removal and disposal of addi�onal asbestos not included in the basic amount. Page 4 of 59 of the solicita�on. We do not have the full iden�fied quan�ty of Asbestos removal and therefore cannot provide a lump sum as proposed in the line item. We would request a quan�ty so we are able to provide a lump sum or could this item quan�ty be changed to a sq � cost and any calcula�on of quan�ty could be firmly established.

The base bid quan�ty covers all aspects of removals within the hazardous materials report.

Refer to materials report for asbestos to be abated in base bid. The 500 S.F, in the line item 0002, is to cover 500 sq � addi�onal unforeseen asbestos.

- There is only one small asphalt patch on this project. It is approximately one truck load of hot mix. The specifica�ons are for a full-blown paving project. Can an exis�ng NDDOT/City of Minot mix design be used such as a NDDOT FAA 43 mix that the city of Minot uses on a daily basis?

- This project is calling for a new asphalt design mix to be developed for a small patch. The mix design itself would cost almost the same amount of the actual paving on this project. Can PG 58- 28 asphalt cement be used instead of PG 58-34? We use PG 58-28 asphalt cement on a daily basis in our Minot asphalt plant, it would be very expensive to buy a tanker load of the other asphalt for such a small patch.

- The tack coat spec is calling for SS-1h emulsion, can CSS-1H be used instead? We use CSS-1H on a daily basis for all NDDOT and City of Minot work. Once again, it would be very cost beneficial to not have to order a tanker of different tack for one small patch.

- Does the jobsite require Temporary fencing around the en�re perimeter?

Yes, Refer to spec section 01 50 00.

- If so, is there a specifica�on on what type of fence is necessary?

Chain link fencing. Refer to spec section 01 50 00 2.3.1. Polyethylene Mesh Safety Fencing was replaced with Chain link Fencing. This was amended in plans and specifica�ons amendment.

- Does this job require a building permit?

Not a building permit, but the job does require clearance work request form 103. Refer to section 01 11 00 1.7 Permits.

- In specifica�on Sec�on 09 67 23.13 ( Standard Resinous Flooring ) Sub sec�on3.2.2 , they are basically calling for a troweled on floor finish with an integral 6” cove base as listed in Sub sec�on 3.2.4, also troweled on. The Room Finish Schedule states that 4” Cove Base is to be applied. The coa�ng they have specified consists of a 5 coat finish system to be applied in the mechanical rooms, the janitor rooms, and the communica�ons room. On the room finish schedule Sheet A-601, it is calling for CB-3. I am assuming that this coa�ng system is what is listed as RF-1.

Plans and specifica�ons amendment gives clarifica�on on RFI.

- Under Sec�on 09 06 00 Schedules For Finishes Sub sec�on 2.3.1.5 , RF-1 is listed as a Resinous Flooring 3-Coat System and under Sub sec�on 2.3.2.2 Integral Cove Base it calls out for CB-2 instead of CB-3 as shown on the Room Finish Schedule.

- In specifica�on Sec�on 09 67 23.15 (Fuel Resis�ve Resinous Flooring, 3-Coat System) which I am assuming to be the ERF-1 it is calling for an epoxy primer with 2 coats of a urethane top coat with an aluminum oxide non-skid addi�ve. ERF-1 is called out to be applied to the toilet areas with CB-2 as the cove base on the Room Finish Schedule. A thin mil coa�ng is not really conducive for an integral cove base as the material is not a trowel applied coa�ng system.

Nowhere in the specifica�ons for this sec�on does it call out for integral cove base. Only on the Room Finish Schedule and Sec�on 09 06 00 does it call for an Integral Cove Base and on Schedule For Finishes it calls out CB-1 not CB-2. Also on the Schedule For Finishes, it calls for ERF-1 to be made of color flakes by Stonetec which is not a 3 – coat thin mil floor system. Is a Fuel Resis�ve Coa�ng actually needed in the toilet rooms?

- I would like a clarifica�on as to what kind of flooring system is to be installed in the loca�ons designated. Are the products to be used open for discussion to provide a system for all areas designated that would give the desired results with a more uniform applica�on?

Yes, the products to be used are open for discussion during the submittal process after contract award. Proposals for the construction contract must be bid per the plans and specifications.
