the deal, the proposal was placed on the November referendum ballot. Leading up to the vote, the Rockets stressed that there would be "no new taxes of any kind", although opponents said the new arena would raise energy consumption, and also contended that the public would pay for too much of the costs of the arena. Contributions for the campaign for the arena included donations of US$400,000 from Reliant Energy, and a total of $590,000 in loans and contributions from Enron and Ken Lay, who the Rockets said was a "tireless" force in the campaign. On November 8, the arena was approved by 66% of voters. Construction According to the agreement signed, the city of Houston bought the land for the arena and an adjoining parking garage, which was near the George R. Brown Convention Center, and paid for it by selling bonds and borrowing $30 million. Morris Architects, designed the building, and Hunt Construction was contracted to build the arena. A building formerly owned by Houston Lighting and Power Company was demolished to make way for the arena, and two streets were closed for the duration of the construction. A groundbreaking ceremony was held on July 31, 2001, and construction continued for 26 months. At the request of Alexander, the arena was built below street level, so fans would not have to walk up stairs to reach their seats. To sink the arena, $12 million was spent to excavate of dirt over four months, which was the largest excavation in Houston history. Concrete was poured for the foundation throughout the summer of 2002, and structural work began in October. The roof was set on in December, as work continued inside, with a peak workforce of 650. In September 2003, a ribbon-cutting ceremony was held to mark the official opening of the arena. The total cost of construction was $235 million, with the city paying $182 million, and the Rockets adding $43 million for additions and enhancements.
