2 Project Description Table 2-1. Construction Schedule Stage Description Duration(Days) Week Nos. 1 Site and Substation Preparation and Grading 80 1-16 2 Energy Storage Enclosure and Substation Installation 180 17-52 3 Gen-Tie Line Foundation and Tower Erection 30 41-46 4 Gen-Tie Line Pulling and Stringing 30 47-52 5 Testing and Commissioning 60 53-64 Hours Construction of the battery energy storage facility would occur primarily during daylight hours, and would not occur earlier than 6:00 a.m. or after 9:00 p.m. in compliance with the San Joaquin County Municipal Code (San Joaquin County 2021). Construction of the gen-tie line or any other Project facilities in Alameda County would not occur before 7 a.m. or after 7 p.m. on any day except Saturday or Sunday, or before 8 a.m. or after 5 p.m. on Saturday or Sunday, in accordance with Alameda County Municipal Code Chapter 6.60 (Alameda County 2020). Construction requirements may require some nighttime activity for material and equipment delivery and/or where the schedule has been delayed due to weather or other events; however, construction equipment usage hours would not exceed what is indicated in Table 2-2. Nighttime activities would be performed with temporary lighting, which would be directed downward to minimize impacts to neighboring properties and wildlife in the Project vicinity. Workforce The onsite construction workforce would consist of laborers, craftspeople, supervisory personnel, and support personnel. The onsite assembly and construction workforce is expected to reach a peak of approximately 60 workers; the average number of workers onsite is anticipated to be approximately 20 to 60, depending on the construction activity, as shown in Table 2-2. Vehicles Construction vehicles would access the Project site from Interstate 580 and Midway Road. Vehicle use of area roadways resulting from Project construction activities would be limited to the 15-month construction period, as workers and materials are transported to and from the Project site. Construction workers would be encouraged to carpool to minimize vehicle trips. Typical equipment during construction would include scrapers, dozers, tractors, backhoes, excavators, and other common types of construction equipment, as shown in Table 2-2. Table 2-2.
