- The Capitol was designed in 1914 by the architectural firm of Layton, Wemyss and Smith.
- Five thousand people attended the groundbreaking ceremony on July 20, 1914.
- The State Capitol was constructed from 1914 to 1917 on two, four-acre tracts of land donated by William F. Harn and John J. Culbertson.
- The construction of the Capitol was begun with day labor to expedite the project while final plans were being completed. On August 3, 1915 a contract was signed with James Stewart Company, Inc. contractors to complete the building upon the then present foundation for just under $1,500,000.
- The State took occupancy of the Capitol on June 30, 1917. The original design and construction of the Capitol incorporated the necessary foundations to support the dome even though the dome was not built at the time.
- The existing structure of the Capitol is reinforced cast-in-place concrete, however, the structure to support today's dome will be structural steel.
- The construction materials for the dome will be:
| Steel Super Structure |
| Architectural Precast Concrete |
| Architectural Cast Stone |
| Inner dome of reinforced plaster casts |
- The project involves removing two million pounds of existing structure.
- New dome weight is approximately five million pounds.
- Dome will be lighted both on the inside and outside.
- The existing stained glass State-seal skylight will be dismantled and refurbished as a historic artifact.
- The Tower crane used to construct the dome is a free standing crane, 270 feet in height with a lift capacity of 15,000 pounds at the furthest extremity of the dome.
- Projected schedule for the construction of the dome on the State Capitol:
| Design and Engineering
August 2000 to February 2001 |
| Construction Pricing Packages
February 2001 to March 2001 |
| Construction
April 2001 to November 2002 |
| Dedication
November 16, 2002 |
- The dome will provide a magnificent crown to the Capitol measuring 157 feet in height above the existing roof and 80 feet in diameter.
- Estimated cost is $20 - $21 million.
- 75% of funds are from private sources.
- The dome will create a new sense of place for the capitol city, a sense of pride for all Oklahomans, and will become a new mecca for tourists.
- A popular misconception is that Oklahoma is unique because it is the only Capitol without a dome. The truth is there are over ten Capitols without domes, but Oklahoma is the only capitol designed to have a dome that didn’t build it.
