To further cool the concrete each form contained cooling coils of 1 inch (25 mm) thin-walled steel pipe. River water was circulated through these pipes to help dissipate the heat from the curing concrete. After this, chilled water from a refrigeration plant on the lower cofferdam was circulated through the coils to further cool the concrete. After each layer had sufficiently cooled, the cooling coils were cut off and pressure grouted by [[pneumatic]] [[grout]] guns. The concrete is still curing and gaining in strength as time goes on.<ref>http://www.riverlakes.com/hoover_dam_info.htm</ref> There is enough concrete in the dam to pave a two-lane highway from [[San Francisco]] to [[New York]].<ref> ~~Lower Colorado Bureau of Reclamation: Hoover Dam, Facts and Figures.~~ [http://www.usbr.gov/lc/region/pao/brochures/faq.html#concrete Lower Colorado Bureau of Reclamation: Hoover Dam, Facts and Figures]</ref> === Construction deaths === Line 178: [[Image:DamTimeZones.jpg\|thumb\|The dam crosses the border between two time zones, the [[Pacific Time Zone]] and the [[Mountain Time Zone]]]] The initial plans for the finished [[facade]] of both the dam and the power plant consisted of a simple, unadorned wall of concrete topped with a [[Gothic architecture\|Gothic]]-inspired [[baluster\|balustrade]] and a powerhouse that looked like little more than an industrial warehouse.{{~~Fact~~Citation needed\|date=December 2008}} This initial design was criticized by many as being too plain and unremarkable for a project of such immense scale, so [[Los Angeles]]-based architect [[Gordon Kaufmann\|Gordon B. Kaufmann]] was brought in to redesign the exteriors.{{~~Fact~~Citation needed\|date=December 2008}} Kaufmann greatly streamlined the buildings, and applied an elegant [[Art Deco]] style to the entire project, with sculptured turrets rising seamlessly from the dam face and clock faces on the intake towers set for Nevada and Arizona time, in the [[Pacific Time Zone\|Pacific]] and [[Mountain Time Zone\|Mountain]] time zones respectively (although because Arizona does not observe [[daylight saving time]], the two clocks show the same time during the warmer half of the year). == Use for road transport == Line 298: ==Construction Artifacts== A fleet of special dump cars were built by Six Companies for use on the railroad that aided construction. Today, one of these cars survives at the [[Western Pacific Railroad Museum]] at [[Portola, California]]. The [[Western Pacific Railroad]] acquired several of the cars following the end of construction and used them in company service. ==See also==▼ * [[Hoover Dam Police]]▼ ==References== <!-- To add a reference simply enclose the text you want to appear here inside a pair in the correct place in the body of the article.
