How do they assemble a basketball court over a hockey rink with such close tolerances?
604630
An NBA regulation basketball is built with wood upon insulated material. The heat on the outside of the court is retained, while the frigid cold from the hockey rink underneath is kept down there, keeping the rink cold. The basketball court is made out of approx. 10' by 10' squares, which are assembled over the hockey rink before a basketball game (or disassembled for a hockey match)

Like basketball, the game is played on a hard court with scoring rings at both ends, and with a ball resembling a basketball (but lighter, smaller and slightly softer in construction). The rings, whilst of similar height and dimension to basketball hoops, do not have a "backboard". The field is divided into thirds which regulate where individuals in each team are allowed to move, and two semi-circular "shooting circles" at each end from within which all scoring shots must be taken.\n\nThere are seven players on each team, who are given nominated, named positions (and in competitive netball must wear "bibs" or "patches" showing the abbreviations below indicating that position). They are only allowed in certain areas of the court, as described below:\n\nNetball positions \nPosition Name Abbreviation Opponent Areas permitted \nGoal Shooter GS Goal Keeper Attacking goal third including shooting circle \nGoal Attack GA Goal Defence Attacking goal third, shooting circle, and center third \nWing Attack WA Wing Defence Attacking goal third and centre third, not shooting circle \nCentre C Centre Everywhere except shooting circles \nWing Defence WD Wing Attack Defensive goal third and center third, not shooting circle \nGoal Defence GD Goal Attack Defensive goal third and center third, including shooting circle \nGoal Keeper GK Goal Shooter Defensive goal third, including shooting circle \n\nBy the combination of the above, only the Goal Attack and Goal Shooter are able to score goals directly.\n\nNetball rules do not permit players to take more than one step in possession of the ball. Consequently, the only way to move the ball towards the goal is to throw the ball to a teammate. The ball cannot be held by one person for more than 3 seconds at any one time. This, combined with the restrictions on where players can move, ensures that everyone on the team is regularly involved in play. Defence is restricted -- not only is contact not permitted, but players must be at least three feet (90 centimetres) away to defend, meaning that hard physical contact is rare. If contact is made, the ball must be passed to the team against which the penalty was committed.\n\nA game is played in 4 quarters of 15 minutes each, with an interval of 3 minutes between the first and second and third and fourth quarters and an interval of 5 minutes at half time. There is up to 2 minutes of time allowed for each injury.

Playing Lines: \nThe outside dimensions of the playing lines should be as follows: \nDoubles 36' x 78' (10.97m x 23.77m) \nSingles 27' x 78' (8.23m x 23.77m) \nAll lines should be not less than 1" (2.54 cm) nor more than 2" (5 cm) in width, except the base line which  may be up to 4" (10 cm) in width and the center line which should be 2" (5 cm) in width. \nClearance Between Courts \nWhere courts are constructed within the confines of a common enclosure, the distance between side lines should be not less than 12' (3.658m). Where space permits, it is desirable to provide additional space between side lines to enhance play; 24' (7.315m) is recommended. \nTennis Court Orientation: \nA tennis court should be laid out to minimize players looking into the sun when serving or when following  the flight of a ball. A tennis court also should be laid out to avoid distracting shadow lines and patterns on the court surface. \n\n\nHope that's alright x

An NBA and official NCAA (college) court is 94 ft long and 50 ft wide.\nA High School court is 84 ft long and 50 ft wide.\nA Junior High court is 74 ft long and 42 ft wide.\nHalf court is well.. half the distance of the full court.. (I know, I didn't need to add that)\n\nThe free throw line is always 15 ft from the line to the backboard\n\nThe distance from the ground to the rim is 10 ft.\n\nThe 3 point arc in the NBA is 22ft to the center of the rim on the sides ( the arc starts 5 ft 3 in from the baseline, being a straight line until that point) then the curved part of the arc is 23ft. 9 in. from the center of the rim.\n\nThe 3 point arc in college and high school is 19 ft 9 in. (The straight part extends 63 in out from the baseline before the arc begins).\n\nThe key is 12 feet wide (the width of the free throw line) the backboard should extend 4 feet out over the baseline. The 12 ft wide free throw line forms the center of a circle with a 6 ft radius.\n\nThe backboard is 72 inches wide by 42 inches high and has an 18 inch diameter rim.\nThe inner square is marked above the rim in a rectangle of 24 inches wide and 18 inches high. \n\nThe line markings are 2 inches wide.

Most NHl rinks are 200 feet long by 85 feet wide but some are slightly different.\n\nInternational rinks are wider by about 10 feet but I am not 100% sure of the exact dimensions.

Spongecraig,\n\nGM Place is built east-west but the Nux practice rinks out in Burnaby are all north-south. This ain't baseball where the sun gets in the batters' eyes and fields have to be aligned facing south in the Northern Hemisphere.

(m)\n\nLength of a basketball court\n94 feet (1128 inches)\nNote: Many high school and college courts are 84 feet.\n\nWidth of a basketball court\n50 feet (600 inches)\n\nSize of a basketball backboard\nWidth: 6 feet (72 inches)\nHeight: 3.5 feet (42 inches)\n\nSize of a basketball rim\nThe diameter of the rim is 18 inches\nThe top of the rim should be exactly 10 feet (120 inches) off the ground\n\nDistance from the backboard to the back of the rim\n6 inches\nNote: In other words, the front of the rim is 24 inches from the backboard (18 inches of which is the rim, and the other 6 inches the flat metal piece connecting the rim to backboard)\n\nDistance from the free throw line to the backboard\n15 feet (180 inches) from the backboard\nNote: Due to the fact that the rim protrudes forward from the backboard, the actual distance from the free throw line to the front of the rim is just 13 feet (not including the elevation factor)\n\nSize of the key\n19 feet (228 inches) from the baseline out of bounds line to the free throw line\n12 feet (144 inches) in width, across the lane\n\nThe basketball 3 point line\nIt's important to note that the 3 point arc is not the same distance from the center of the rim at all spots. This results from the fact that on the baseline, the 3 point arc begins with a straight line, before starting its curve. Once the curve begins, the distance stays consistent all the way around the arc.\n   For the college and high school 3 point arc, there is a straight line of 5.25 feet (63 inches) that runs until the arc begins. For the NBA 3 point line, there is a straight line of just over 14 feet (approximately 169 inches) before the 3 point arc begins.\n   Once the 3 point arc begins, the college and high school 3 point arc is 19.75 feet (19 feet 9 inches, or 237 inches).\n   The NBA distance is 23.75 feet (23 feet, 9 inches, or 285 inches). However, on the baselines, with a line drawn directly from the center of the rim to the sideline, the NBA distance is 22 feet (264 inches).\n\nThe markings around the key\nThe blocks are exactly 12 inches in width, and 8 inches deep. The other three tabs on each side of the lane are two inches in width, and 8 inches deep. The distance between the baseline and the block is exactly 7 feet. The distance from the end of the block to the first line is 3 feet. Each additional line is another 3 feet (36 inches) away from the end of the previous line. However, with each line being 2 inches in width, the distance from the beginning of the first block to the beginning of the following line block is 38 inches.\n\nThe circle above the key\nThe radius of the half circle above the key is 6 feet (72 inches). The diameter is obviously equal to the width of the key (or the length of the free throw line), 12 feet (144 inches). \n\nThe NBA charge line\nThe new NBA charge line (in the NBA, players must be outside this arc to take a charge) has a radius of 4 feet (48 inches). The radius' origin is directly under the center of the rim. The arc stops at a point even with the center of the rim.

this game comes from the american indians. a hard ball is cradled in a leather woven basket that is open and attached to a approximately 3 foot pole. players rock the stick above their heads to keep the ball in the cradle and run down the field to throw the ball into the oppponents net. like field hockey but in the air instead of on the ground. colleges like this game, esp on the east coast

they freeze the water artificially.  ie; there's cooling equipment under the ice, so it doesn't have to be below freezing in the arena.

a basketball will bounce the highest of these objects because it is mad of a harder material whose material will retain its shape more readily than the others. also it has higher air pressure inside.

The only essential equipment in basketball is the ball and the court: a flat, rectangular surface with baskets at opposite ends. Competitive levels require the use of more equipment such as clocks, scoresheets, scoreboards, alternating possession arrows, and whistle-operated stop-clock systems.\n\nThe men's ball's circumference is about 29.5 inches (76 cm) and weighs about 1 lb 5 oz (600 g). The women's ball's circumference is about 28.5 inches (73 cm) and weighs about 1 lb 3 oz (540 g). A regulation basketball court in international games is 28 by 15 meters (approx. 92 by 49 ft) and in the NBA is 94 by 50 feet (29 by 15 m). Most courts are made of wood.\n\nA cast-iron basket with net and backboard hang over each end of the court. At almost all levels of competition, the top of the rim is exactly 10 feet (3.05 m) above the court and 4 feet (1.2 m) inside the endline. While variation is possible in the dimensions of the court and backboard, it is considered important for the basket to be the correct height; a rim that is off by but a few inches can have an adverse effect on shooting.

They would just work the schedules - You are also assuming they would all have home court/ice advantage - the games are spread out enough. It's also happened in Boston or Phoenix, I think - I'm sure somewhere else - where they played a hockey game during the day, then they just lay the basketball floor over the ice surface and play a night basketball game. The same scheduling conflicts occur all regular season, you know - the leagues just work together.
