Blenheim-Gilboa Vertical Shaft Inspection

Due to the unique nature of this project, McLaren’s team of engineering and surveying specialists developed special procedures for measuring and mapping elements of NYPA’s system. This required the design and fabrication of an equipment package capable of photographing and measuring the shaft over its 1000 foot depth. McLaren, responsible for overall project management, also developed a conceptual design of an equipment package capable of facilitating the inspection of the vertical shaft and transition elbow. The design and fabrication of this rigging system allowed for proper movement of the camera equipment to facilitate the inspection of the 28-foot diameter vertical shaft and transition elbow's internal surfaces.
