2 PRE-BID MEETING MINUTES DATE & TIME: September 27, 2017; 2:00 p.m. PROJECT: LOCATION: BID DATE: City of Kenner Sewer Capital Improvement Program Wastewater Treatment Plant No. 3 Generator Banking Sealed Bid No A/E Project No City of Kenner Public Works Auditorium 1610 Rev. Richard Wilson Dr. Kenner, LA All bids are to be submitted on October 9, 2017 by 9:45 a.m. to the City of Kenner Purchasing Department, 1801 Williams Blvd. Building C, 3 rd Floor, Kenner, LA Bids will be opened and publicly read at 10:00 a.m. in the City of Kenner Council Chambers, 1801 Williams Blvd., Building A, Kenner, LA I. Introduction a. Introduction of attendees including the Owner, Project Engineer and their representatives. II. Project Scope a. Scope of Work, type of construction, and special features i. Overview: As a result of the recent population growth experienced by the City of Kenner, WWTP No. 3 has been expanded over the past few years. The expansion has necessitated additional electrical services for the increased loads, but existing standby power is no longer sufficient to operate the plant at full capacity. This project addresses the additional standby power needs of the plant. Under the project, the Contractor will construct facilities and provide equipment required for a banked standby power system for WWTP No. 3. At the completion of this project, banked standby capacity will be increased from 1.8 MW to 3.4 MW (an increase of 1.6MW) with provisions for future expansion up to 4 MW of standby power, including a redundant 800 kw generator. ii. Project is primarily electrical in scope, and, in general, consists of furnishing and installing two new, 800kW packaged engine generator sets, retrofitting and relocating three existing 600 kw packaged engine generator sets, furnishing and installing new paralleling switchgear and associated controls as necessary for paralleling all 5 generator sets, furnishing and installing new distribution Page 1 of 6

3 equipment, providing associated underground duct banks for feeders and controls, providing temporary standby power during construction, and providing new service disconnecting means that will facilitate connection of a roll-up generator for the Administration Buildings. Electrical scope also includes generator pad site lighting and power and lighting associated with new utility buildings. iii. As part of the Civil / Structural work, a pile-supported concrete pad will be constructed, sufficient in size for up to 6 generator sets, utility buildings, and a large-capacity diesel fuel storage tank. A curb around the pad will be constructed, drainage will be provided, and site grading will be required. iv. Under the base bid, two buildings will be constructed one for the paralleling switchgear, and a second for the standby distribution board SDB. The building for the paralleling switchgear is tilt-up precast panel construction; the building for distribution board SDB is modular, pre-cast, shipped-to-site. The buildings are specified separately in sections and 13343, respectively. If Bid Alternate No. 1 is accepted, then a third modular, pre-cast building will be provided to house the fuel system transfer pumps, fuel polishing system, and fuel valve controls. v. Under Alternate No. 1, scope includes providing a large-capacity, on-site diesel storage tank, concrete fuel building, fuel transfer pumps, fuel filtration, fuel distribution piping, and associated controls as necessary for automatically filling generator set sub-base day tanks. vi. Under Alternate No. 2, scope includes providing roll-up generator connection boxes in two locations. vii. Under Alternate No. 3, scope includes providing pole-mounted HID light fixtures and associated controls for night work. viii. Field Surveying is required for field verification of grades, limits, and utilities will also be required. Please refer to Section b. Project Specifics: i. The plant is currently served by three utility transformers: one for the Administration Area, one for the Old Plant, and a third for the New Plant, which consists of the recently constructed Effluent Pumping Station and Headworks Structure. The three existing generators serve the Old Plant directly. Reduced-capacity standby power for the New Plant is currently provided via distribution equipment in the Old Plant. ii. Once the new standby system is operational, the New Plant will receive fullcapacity standby power directly from the paralleling switchgear. Automatic transfer switchgear is already in place to receive the full-capacity feeder. iii. Temporary standby generator power will be required for any portions of the project where existing standby capacity is removed from service. Anticipating that this will happen when the existing generators are relocated and retrofitted, and recognizing the combined capacity of those generators is 1.8 MW, we are Page 2 of 6

4 requiring that a 2 MW rental be furnished for the length of time the existing generators are out of service. If distribution board SDB is installed, commissioned, and tested before the existing generators are relocated, the equipment may be utilized for temporary power to the Old Plant. Should the Contractor instead choose to relocate the existing generators before Switchboard SDB is operational, the Contractor will also need to rent temporary distribution equipment to re-feed the Old Plant. iv. Project will require modifications to existing PLC equipment located in existing MCC-ECF and existing transfer controller in switchgear MSG. v. The existing packaged engine generator sets are manufactured by Cummins Power Generation. Existing ATS switches are also manufactured by Cummins. To that end, the basis of design for the new generators and paralleling switchgear is also Cummins Power Generation so that there is a single source of responsibility for the standby power system equipment. vi. Environmental: Please be sure to meet all EPA and SPCC guidelines as they pertain to diesel fuel oil spill prevention and containment. This will be particularly important when relocating generators 1-3. vii. Permits / AHJ Reviews: 1. Contractor will be required to submit shop drawings associated with the fuel storage system, including generator day tanks, to the SFM for a Fuel Tank Storage Review. Contractor will be responsible for the required review fees. Review fees can be found online. Estimated review fee is $75 for the first tank and $30 for each additional tank. 2. Each modular, set-in-place building will require a separate Industrialized Building review by the SFM. Contractor will be responsible for submitting shop drawings and paying associated fees. Review fees can be found online. Estimated review fee is $ per building. c. The Contractor is responsible for the layout of the work. Data for control points for the Contractor s use are included in the drawings. d.
