Project Construction Photos
Workers clear vegetation as expansion of Echo Lake Substation gets underway.
Workers clear vegetation as expansion of Echo Lake Substation gets underway. Silt fences will keep disturbed soil on site. Construction equipment is being inspected before it enters the Cedar River Municipal Watershed. Towers arrive at the fly yard for tower assembly. Crews begin assembling a tower base.
In order to erect the towers they must first be assembled one by one. Crews use cranes to assemble tower bases for the new transmission line. Trees are flown out of the watershed by helicopter. BPA agreed to use helicopters to minimize disturbance within the watershed. The logs are carefully lifted out of the watershed and taken to a remote area several times a day. BPA has agreed to steam clean all vehicles and equipment that are used inside the watershed.
Workers prepare to place concrete reinforcing at the drilled shaft for the river crossing double circuit structure. Barrel drilling a pilot hole for the shaft foundations for the double circuit river crossing structure. BPA discontined the use micropiles, new footing method, because they displayed greater ground disturbance than expected. BPA is now using conventional footings in the watershed. The tower body is being lifted by Air-crane helicopter out of the fly yard into the watershed. The Air-crane helicopter is lifting the mid-section of the tower onto the tower base.
The construction workers await the Air-crane helicopter to hook tower to the helicopter. Lift-off from fly yard. Air-crane will fly the tower into the watershed. The Air-crane flys over right of way with a tower bridge. The Air-crane hovers while the construction crew hooks the tower to lift out of the fly yard. The tower bridge is carefully lifted from the fly yard to be taken into the watershed nearly three miles away.
High above ground, the tower mid section is approaching its destination atop a tower base. In November 2003, the Puget Sound area got hit with a strong wind storm. This photo shows 276th street near the Kangley project. Trees down within the Cedar River Watershed. Trees down within the Cedar River Watershed. A large tree lies on top of the conductor.
The impact of the winds was so strong that small wood chips were seen in the conductor. Trees fell onto the conductor. BPA TLM crew working about 220 ft above ground at the Schultz-Raver tap point. TLM getting ready to do last jumper on Wednesday, Dec. 31, 2003. TLM installing jumpers at Echo Lake.
