Ken, Thank you for you consideration We represent Alcotex which is a high-quality MCM manufacturer, and it meets the specification for the BCRTA - Chestnut Street Multimodal Station project and as such. I attached a product testing sheet which compares our sheet to Alucobond and Alpolic. If this comparison chart shows that our product meets your standards, would you be opposed to adding it to your master specification for MCM/ACM future projects? I’ve also attached a substitution request form. If it does not meet the requirements, could you share which items are the shortcoming? Thanks

Spec section 23 31 13 3.9 calls for duct cleaning to be performed on this project. Will this be required since the duct will be new, have the ends covered from the time it leaves the factory through installation, protected while on the job site but not installed and have temporary media covering all of the return air openings from start-up to turnover?

There is a single wall rectangular spec (23 31 13 2.2) and a single wall round spec (23 31 13 2.3) but no dual wall spec for rectangular or round. Does this mean that any duct systems called out to have liner is only referring to the rectangular and the round will be single wall with external insulation of the required thickness applied?

Spec section 23 31 13 2.4 A. through F. lists 5 different types of metal that could be used on this project. Spec section 23 31 13 2.4 G. calls for antimicrobial to be factory or shop applied but it does not mention anywhere in spec section 23 31 13 that tells which ducts this coating is to be used on. Please note that this coating is very expensive, so we need to know: o If this coating is going to be required? o What specific materials will need to have this coating applied if it is required?

Butler County Regional Transit Authority
Antimicrobial coating is required on the interior duct surfaces per specification 23 31 13. Ductwork that requires lining may be provided with antimicrobial treated liner instead of interior surface treatment.

1. From the Narrative prepared for the Multi-modal Connection plan (pg. 28 of 35), the bus wash facility “will be used to maintain BCRTA buses, as well as vehicles owned by the other project partners. “ Additionally the Narrative states, “Altogether, the proposed wash facilities will contribute to the long-term operation of over 300 vehicles, including 50 BCRTA buses, 35 TSD buses owned by contractor Petermann Bus, 120 City of Oxford vehicles, and 143 Miami University vehicles.” Does BCRTA have a list, including length and type of vehicle, that will be processed through the bus wash facility?

Butler County Regional Transit Authority
Bidders should rely only on the bid documents and specifications to fulfill the scope of this project. The documents referenced in this question are not part of the bid documents, are out of date, and do not reflect the most current business requirements of the system. The system will not be required to clean school buses or the full City fleet, but will be required to wash BCRTA's 35 ft coaches, light transit body-on-chassis "cutaways," and minivans as well as Miami University fleet vehicles and service trucks. A fleet list is included as reference only and should not be construed to dictate a specification.

30. Bus Wash Design Concern 2 Apr 3 2023 at 2:50 PM

Anonymous Apr 3 2023 at 2:50 PM
User information is private
2. From the animation of the new facility on the BCRTA website, and from pictures of Miami University and Petermann Bus school buses, it appears that buses up to 40 ft in length will be processed through the bus wash equipment. Although we can bid on the system as designed, we have reservations about the ability of the specified bus wash system to wash not only longer vehicles such as school and transit buses, but also the City of Oxford vehicles. Longer Vehicles/Buses: Based on the sequence of operation identified in the specifications (11 11 26 Sect 2.2), the bus will first need to stop to have the front washed, then pull forward and stop again to wash the rear of the bus. Transit and school buses can be 40 ft in length. If such buses are run through the wash system as designed, the bus will stop in the middle of the wash sequence and will be stopped while inside the high pressure and rinse arches. This is not recommended. Either those functions will need to shut off while the rear of the bus is washed, or the arches will remain on resulting in unnecessary water and energy usage. City Municipal vehicles: Municipal vehicles vary widely in shape and size, from passenger vehicles to dump trucks or work trucks. Brushes, or friction cleaning, are good for cleaning smooth and flat side vehicles such as buses. Using brushes to clean municipal vehicles such may not be optimal. Municipalities with diverse fleets are often best serviced using a combination of friction and touchless cleaning. When washing with high pressure, the application of detergent is especially important for effective cleaning. Although the specified system has a high-pressure arch, there is no provision such as a separate arch for detergent application other than through the brushes, which in a high-pressure, touchless mode are not active. While not engaged in the design of the system, and although we can bid in accordance to the specified wash sequence, we feel many of the project’s listed stakeholders may be disappointed with the capability of the wash system. The wash as specified lacks the functional flexibility to effectively wash a wide array of different vehicles. As such, we recommend the wash system be deleted from the bid as, in our view, it is not capable of delivering fully on its intended purpose.

The vehicle wash system is designed to accommodate the fleet used by the facility and any additional vehicles that the BCRTA expects to use the wash system. The prospective vehicle wash system for the facility shall meet the requirements of all vehicle wash system drawings, specification section 11 11 26 vehicle washing equipment, and accommodate the wash building footprint/architecture. The camera reading system information can be found in specification 28 20 00 (section 2.4). The vehicle wash system specification (11 11 26 2.2.F) was updated in [this] Addendum to reference the appropriate specification section. The vendors for cameras/security and the wash equipment are separate though they will be integrated together to provide access to the wash building/system. The location of the license plate reading system camera was adjusted from the fueling canopy to a pole in the vicinity of the wash in ES1.1 Addendum #5, per the manufacturer’s recommendations for this type of application.

If there are any upcoming addendum I'd like to be added to the section 07 54 23, 2.1 MANUFACTURER A. TPO Membrane Roofing System: 4. Elevate (Formerly Firestone Building Products): www.holcimelevate.com

Rejected. Substitution request did not contain enough information (accompanying system components were not included in substitution request) to make a substitution decision prior to “end of question” period. In addition, specification has multiple manufacturers to select from that meet the performance requirements.

There seems to be conflicting information on the drawings as to the location of terrazzo base. For example, A10.2 calls for TRZ-1 base throughout the Public Concourse. However, sections 8&9 on A7.9 refer you to Tile Base Detail 14/A7.9. Other sections in the Public Concourse area show a 4" tall cove terrazzo base such as sections 1&3 on A7.9. A third section call for a 6" tall straight precast terrazzo base as shown in 1/A5.15. Please clarify the type of base to be used at the terrazzo flooring.

Notes on these drawings have been updated to clarify that the base is the same all the way around and is integral with the floor. The terrazzo wall base shall be 3 ¾” tall. These drawing changes are included in Addendum 5.
