OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Pavement sub grade filling continued within the NE project limits. The material used is an onsite
generated urban fill consisting of F - C gravel and sand, little silt containing various debris such as
wood, brick, slag, ash, glass, metal, organics ETC. The material was also recently tested for organic
content and was shown to contain 11.3% organic material content. The material was recommended to be
amended to achieve a reasonable organic content. The site contractor was directed to use the material
to finished sub grade elevation in pavement areas without amendments despite the recommendations of the
geotechnical engineer. 12 - 18" thick lifts were placed and graded utilizing the Deere D6 bulldozer.
Each lift was compacted utilizing the IR 10 ton drum roller. Some minor rutting and weaving conditions
were observed during densification.
Installation of drainage utilities was performed at the West side of building 2. The trench was
carried down to design elevation utilizing the Deere 380 excavator. CB 11 was installed. The structure
