Gentlemen: Mr. Daniel I.-long GRADING REPORT Future Park Site Hawaii ·Loa Ric:Jge Wailupe, Oahu, Hawaii At your request, we have observed the grading operations for the Future Park Site of the subject deveJopment. This work has been completed on an intermittent basis. -work commenced with a general clearing and stripping of the area to be graded. Soft spots were removed and recompacted. Actual grading then commenced using 631C scrapers~ D-8 and i:>-9 bulldozers, and an 8248 caterpillar compactor to haul, place, and compact the _fill materials. The majority of th~ excavated materials utilized in the construction of the fill embankment consisted of crushed basalt cobbles and boulders which were utilized in the rock filling operations. Moderately plastic clays and silts (MH) were utilized in the upper portion of the filL An 18 inch thick "choke" layer of crushed basalt .gravel was used in transitions between rock and soil fills to prevent migration of the fines into the open-graded rock fill below. The majority of the materials was generated 'from the excavations of the Major Access Road. Rock fill was spree~d in maximum lifts of 18 inches in thickness and compacted by tracking with D-:'8 and 0-'9 bulldozers. Soil material was spr.ead in 8 inch lifts~ moisture conditioned and compacted with a caterpillar 8248 tamping compactor • Field observation and density tests performed by our tirm Indicated that adequate compaction was being obtained. These tests showed values in excess.of 90 percent relative comp;;Jction :as determined by ·~~rat9ry Compaction Test ASTM D1 557. . ~~·~ · .
