A quick Google check found lots of tidbits but no name of a construction company or the names of the shapers?

Configuration: Whistling Straits is comprised of two 18-hole courses: The Straits® and The Irish.
Opening dates: The Straits – July 1998 The Irish – July 2000
History of the site: In the 1950s, for approximately 9 years, the site had been used by the U.S. Army as an antiaircraft training facility called Camp Haven. Previously it was pancake-flat farmland.
Sheep: A flock of Scottish blackface sheep was acquired for Whistling Straits, with the intent that the animals wander the property freely as might be encountered on a country course in the British Isles. The sheep are kept on-site during the golfing season (they are moved to an offsite farm during the winter months).
Bunkers: The sand bunkers constructed for the course are composed of sand native to the area. Not all of the sand was original to the Whistling Straits property; additional sand from a site located 10 miles from the course was brought in to complete construction. In building The Straits, 7,000 truckloads of sand - approximately 105,000 cubic yards - were brought to the site. Maintenance of the bunkers is intended to be natural by the elements, primarily the wind; staff maintenance is minimal.
