With this becoming the situation, you shouldn't count on a WEAP prediction using "setup time = 168 hrs" to correlate with the onsite noticed circumstances affiliated with EOID, or "set up time = 0 hours." Mainly because this time variable may be manipulated, it is suggested to complete multiple WEAPs connected with EOID (t=0 several hours) Micropile installation equipment as well as other time increments pertinent to the specific task requires.
