Intermittent road restrictions continue as hydro project progresses
The mild weather this week has allowed crews at the Red Rock Dam to continue working day and night to prepare the site for construction of a powerhouse and intake structure that will comprise the Red Rock Hydroelectric Project (RRHP). Short-term road closures, directed by the Marion County Sheriff’s Department, will occur in the overnight hours every three to four days as crews move large rebar cages from the North Tailwater staging area to the construction area on the upstream side of the Dam. In addition, Highway T-15 will be restricted to one lane every three to four days to facilitate staging of the concrete trucks to ensure worker and public safety as the wall element sections are poured.
Downstream work prepares for RRHP powerhouse construction
Construction continues at the Red Rock Dam where Missouri River Energy Services (MRES) will construct a new hydroelectric power plant. Much of the construction work being done is in preparation for construction of the powerhouse, which is expected to begin in summer 2015.
On the downstream side of the Red Rock Dam, the construction of the cofferdam, which is located between the Des Moines River and the power plant site, is well underway. The construction of Cells #1 and #2 are largely complete, Cell #3 is being filled with sand, and the walls of Cell #4 are being installed.
Independent review panel studies and approves construction thus far at Red Rock Hydroelectric Project
SIOUX FALLS, S.D. – A four-member panel of experts in dam and hydroelectric project design and construction has given its approval to construction work thus far at the Red Rock Hydroelectric Project, located on the Des Moines River near Pella, Iowa.
An Independent External Peer Review (IEPR) Panel was on site at the project Jan. 14-15 to review reports, tour the facilities, observe construction activities, and examine various construction elements.
