Kipco Inc had mobilized to the site a 350 Excavator,mid sized dozer,and a Dynapac 15-ton vibratory smooth drum roller. At the time of the site visit the majority of the strippings had been removed from the site. Across the building pad area the approximate fills to the top of the structural fills were laid out. Fills ranged from 3.0-feet to 5.5-feet with the highest areas of the stripped subgrade being along the north and east sides of the buildings and the lowest portion lying near the southwest corner of the building pad. The building pad area was sufficiently stripped of topsoil and the native silty sandy soil was exposed. The excavation contractor planned on beginning to import 3"-o crushed quarry rock beginning the next morning and a subsequent visit was scheduled. There was discussion regarding Item#1 of Addendum No.2, densification of the native soils. February 27.2014: Branch Engineering,Inc.geotechnical engineer of record and representative met at the start of the day with the excavation contractor and general contractor regarding the compaction of native soils. Both the general and the excavation contractor proposed placing a 1.o-feet thick lift on the native soil before running heavy compaction equipment due to concerns with the softness of the soil and the suitability of the equipment. BEI requested that a first lift thickness of 6-inches be attempted and some compactive effort put into the native soils due to the unconsolidated nature of the material. A return visit for test strips and proof rolls was scheduled for later in the day. A BEI representative returned to the site at approximately 12:00 to observe the placement and compaction of 3"-o structural fill. A test area was established and a first lift thickness of 6-inches was placed and a few passes with a vibratory smooth drum roller were placed on the lift. A second 6-inch lift was placed and subsequently compacted. A loaded dump truck was used for proof rolls on the material and significant deflection and pumping under the tires was observed. A second test area using a lift thickness of 1.o-feet was established. A proof roll was conducted with another loaded dump truck and a similar amount of deflection and pumping was observed. Provided that the contractor can achieve acceptable levels of compaction of the 3"-o fill material and 95%max.dry density(per ASTM 1557)of the top 1.0-feet of 3/4"-0 crushed aggregate a first lift thickness of 1.o- feet is acceptable for the fill in the building pad. February 28,2014: A BEI representative visited the site at approximately 10:30 a.m.and observed 3"-o crushed aggregate fill being placed and compacted on the building pad. The pad was approx.50%covered with crushed aggregate and the lift being placed was approx.1.o-feet in thickness. Loaded gravel trucks were in the process of delivering the aggregate and were observed traveling on the freshly compacted lift. Some deflection of the aggregate mat is present under the truck traffic but appears to be improving with sustained traffic and compaction. Item#2 of Addendum No.2 was discussed with representatives of Kipco Inc.and Chambers Construction,3.o-feet of compacted crushed aggregate is required beneath the bottom of the perimeter footings. BEI,Kipco Inc.,and Chambers Construction reviewed the perimeter footing details(t4/Sheet S3.1 and ao/Sheet S3.2). .......... .. . ....

CONSTRUCTION OBSERVATION REPORT Date: March 8,2013 Project: Giustina Resources—Liberty Professional Center Project No.: 12-181:01 BEI Field Representative: Matthew Renner Re: Column Footing and Perimeter Footing Over-Excavation March 4,2013 A Branch Engineering,Inc.(BEI)geotechnical representative visited the site of the Liberty Professional Center at approximately 10:00 to observe the over-excavation and placement of CLSM material underneath the future column foundation footings. Kipco Inc.was on-site and in the process of excavating to the existing bar-run gravel at the column footing locations,CLSM was concurrently being delivered and placed as work conditions allowed. Five excavations were open with the bottoms of the excavations visible and found to be advanced to satisfactory depths. During the time of the site visit 8-footing excavations,primarily along the southern portion of the building footprint were observed;either filled with CLSM,open,or in the process of excavation. No sidewall caving or sloughing was observed in any of the open excavations. March 9,2014: A BEI geotechnical representative visited the site of the Liberty Professional Center at approximately 9:00 to observe the over-excavation and compaction of aggregate fill underneath the future perimeter footings to be placed along the edge of the building footprint. At the time of the visit Kipco Inc.was in the process of over-excavation along the northern building edge. The depth of the excavation was being set by Kipco Inc.with a laser level and was to accommodate 3-feet of compacted aggregate underneath the perimeter footing. The subgrade material exposed was consistent and appeared to match the descriptions of the test pit logs(silty fine-grain sand). Aggregate removed from the footing excavations was free of contamination from native soils and placed back in the excavation to be compacted with a back-hoe mounted hoe-pack. March 8,2014: A BEI geotechnical representative visited the site of the Liberty Professional Center at approximately 1:30 to perform density tests on compacted 3/4"-o aggregate fill placed underneath future perimeter footings. The fill was compacted and brought to grade along the north and east boundaries of the building pad. Density tests were taken at 4-locations along the north and east boundaries,the results of the tests ranged from 95%to loo+%of a modified proctor(AASHTO T-18o).

Re: Base Rock—Proof Rolls October 1S. 2014: A representative from Branch Engineering,Inc.(BEI)visited the above referenced site to observe proof rolls with a to CY loaded haul truck on the shared roadway accessing the Giustina site parking lot and the site to west that is yet to be developed. Proof rolls were conducted across the full width of the roadway from the approach at International Way to the northern end of the roadway. Minimal or no deflection of the base rock under the load was noted. The proof rolls were discussed with Jack Makarcheck from Chambers Construction and a return visit to perform density tests the following day was scheduled.
