Week ending December 18, 2020
Construction activities were slower this week as the project was dealing with vandalism which destroyed equipment and pumps over the past weekend and the snow event Thursday. Once resumed, active placement of the granular material continued. This material will serve as the base for the tanks and numerous geotechnical engineers visited the site to evaluate the material and compaction efforts. Two concrete spanning beams were placed to provide additional bracing at the bottom of the excavation between the sheet pile walls.
The team at Sebago Technics, which is providing our project oversight and inspection services, also provided us this week with the below link to aerial drone footage from the site.
