A site in Rhode Island underlain by loose to dense sand was to accommodate the construction of a submarine assembly building (SAB). The SAB was a one-story, 90-ft-high, steel frame industrial building with column spacings of approximately 75 by 205 ft. Maximum design column loads were approximately 1,600 kips. Inside the building were computer-controlled welding machine fixtures used to assemble the submarine bodies with precision tolerances. The fixtures were about 55 ft in diameter. Differential settlement tolerances of the welding machine fixtures were very small, whereas settlement tolerances of the building were consistent with flexible steel frame construction. Standard penetration test N-values in the sand deposit were generally higher than 15 blows/ft. However, within a depth of 0 to 10 ft below proposed footing grades, some areas exhibited N-values as low as 4 blows/ft. After evaluating several foundation schemes, spread footings (designed for 3 TSF) were selected to support the building. The footings would bear on a natural sand subgrade densified to a depth of about 6 ft by multiple passes of heavy vibratory rollers. The feasibility of subgrade densification was verified by a field test section using standard penetration tests, cone penetration tests, and plate load tests. Production densification was verified by cone penetration testing. The engineering evaluation, the field test section, and production verification test results are described.
