Thompson v. H. B. Zachry Co‪.‬

Defendant, H. B. Zachry Co., who was performing construction work on the McGregor Range, employed the plaintiff, Thompson, to perform certain surveying work at an agreed rate of compensation. Thompson was required to survey and stake the Hawk access road and sites for sixteen concrete launching pads, in accordance with drawings and specifications indicating their locations. It was discovered that Thompson had incorrectly located the road, but such revelation was not made until after the defendant had already done some construction work at the erroneous location. Plaintiff resurveyed the location without charge. Subsequently, two launching pads were also incorrectly located and the error corrected, but the defendant was required to rebuild forms at those two launching pads as a result.
