PROJECT: Colorado River Storage Project Act (1956); Glen Canyon Dam (GCD) & Glen Canyon Reservoir (now Lake Powell) in northern Arizona; principal agency is Bureau of Reclamation (Reclamation).
- Commissioner of Reclamation in 1957: Wilbur A. Dexheimer
- Commisssioner of Reclamation in 1959: Floyd Dominy (oral history)
- Chief Engineer (onsite) for GCD Project: Lemuel (Lem) Wylie
- Chief Design Engineer of Concrete Dams: Ernest R. Schultz (design features)
- Public Affairs Officer for GCD Project: W.L. (Bud) Rusho (oral history)
- Contractor: Merritt-Chapman & Scott Corporation, New York City.
- A dispute from the labor force emerged at the beginning of the project.
- The Merritt-Chapman & Scott Corporation suffered bankruptcy and by 1971, operations were dissolved. Wikipedia.
There were nine baseline objectives to complete the construction of Glen Canyon Dam:
- Navajo sandstone as bedrock for this facility was the greatest challenge for the design engineers. GC Dam is the first dam by Reclamation to utilize computer programming to calculate the stress load of a cantilevered arch dam. GC Dam is not a gravity dam. To qualify as a gravity dam, the dam's weight must exceed the load and the hydraulic lift potential of a full reservoir.
- Build a community (Page, Arizona) with utilities (water, power and sewage), provide housing, warehouses and office space for a federal bureaucracy and for contractor and sub-contractor employees.
- Build a highway bridge to connect the western and eastern rims of a wide and entrenched Glen Canyon.
- Preparations to dewater the river and expose the bedrock below the sand and gravel beds (photos of paleoflood scour).
- Preparations to build forms to accept a matrix of reinforced steel and concrete, and then circulate refrigerated water through pipes to dissapate the heat of setting concrete. This includes the batching of sand, gravel, portland cement and pozzolan (a binder of volcanic origin).
- Grouting and rock bolts: (1) Drill holes into bedrock to install rock bolts to prevent the delamination of Navajo Sandstone. (2) Drill holes through the hardened concrete and/or bedrock to inject grout to seal the voids and cracks and prevent seepage and hydraulic lift of the superstructure (two phases of injection: low-pressure & high-pressure). Note: The dam does leak and sandstone slabs do exfoliate (AGU paper); this will be discussed at a later time, below.
- Prepartions to build a powerhouse of turbines and a network of transmission lines to distribute electrical power.
- Seal (plug) the diversion tunnels with concrete and fill the reservoir, which took 17-years, and more on that subject at a later time. General Principles to Govern, and Operating Criteria for, Glen Canyon Reservoir (Lake Powell) and Lake Mead During the Lake Powell Filling Period.
- Build a Visitor Center and organize a dedication ceremony by Lady Bird Johnson.
