Our testing and observations for this date include the following: FO-1 : Field Observations made on this date. • DCPs For Lot 84 Passed • Project Management Review Passed ST-1 : In place field density testing was performed for Finished Subgrade Soils -Building. The field density testing was performed in general accordance with ASTMD1556, using the results of field one-point as compared to the laboratory proctors. One(1) in-place field density test was performed on this date. The testing results indicate that in-place compaction and moisture content at the location and depth tested meet or exceed the specified requirements outlined in the project plans and specifications. For additional details of our testing, please refer to the attached Field Density Test Report. Closing The testing and observations identified above have been reviewed by our project manager.

Michael Caldwell Monitoring: DCP 1 : DCPs For Lot 84 Passed We arrived Onsite to evaluate the building pad area for this residential lot.We understand the residence has been designed to be supported on a monolithic slab foundation.Upon arrival,the contractor had not finished excavating the footings.Our evaluation as documented in this report includes: 1)A visual description of the residential lot 2)Comments on any improvements that hal affect the foundations of the residence 3)Hand rod probing of the footing excavations 4)Performing Dynamic Cone Penetration(DCP)tests at representative locations 5)Soil Density tests on fill,it applicable. Visual Description of the Lot: The lot is generally slopes or is relatively flat,the lot slopes:front to back.Building locations are referenced from the street looking at the front of the residence.Maximum relief across the lot is approximately 3 feet.Surface water runoff appears to drain from front to back. Comments on Improvements: The site has been stripped of surface cover and topsoil, has been stripped but still appears to have a layer of organics that need attention.It appears that 8-10 inches of topsoil has been removed from the building pad area, Structural fill has been placed at the site to level the building pad.Based on our observations,we understand the pad has been filled according to the following: Section Thickness of Cut or Fill Left Front 24 inches of fill Left Rear 24 inches of till Center 24 inches of fill Right Front 24 inches of fill Right Rear— 24 inches of fill Future Footing Tests Hand Rod Probing:Our representative performed hand rod probing of the surface of the building pad.Hand rod probing of the bearing material generally showed an average penetration of approximately 4 inches. DCP Testing:Our representative performed Dynamic Cone Penetration(DCP)testing in general accordance with ASTM STP-399 at four representative locations to a depth of 36 inches. Our representative did not observe water within the DCP boreholes as noted below.

Results: Based on our observations and test results,the newly placed fill/existing soils appear to be suitable to provide support for the floor slab and footings, provided the floor slab has a loading of less than 150 pounds per square foot, and the footings have a design bearing capacity of 2,000,or less. Recommendations: To minimize the potential for future softening of the bearing materials due to water infiltration,the surface soils should be protected from construction traffic and inclement weather.The construction of the footings and structure should commence without delay.In the event that the subgrade soils become wet.or otherwise compromised from their current condition,should be observed and retested as necessary by Building and Earth Sciences. 610 Spring Branch Road (,.q 11 Dunn,NC 28334 Phone 910.292-2085 Fax 910292-2192 tame buildingendEarth mm Reviewed By Page 3 of 6 voicuiNG a tnam 03/20/2018 Field Observations Report Project Name: Lot 84 Cooper Creek CPC(CMT)Spring Project Number'. RD180139 Lake,NC Client Name: H&H Homes Placement#: FO-1 Contractor: H&H Homes Technician: Michael Caldwell Monitoring: DCP We note that our testing was isolated to the upper 3 feet of the sod profile from the finished subgrade elevation as observed on this date.As such,we cannot be aware of any soil or groundwater conditions below this depth that could adversely affect the support of the new construction.If additional information is required,please contact our office. 2: Project Management Review Passed Our client has authorized Building & Earth Sciences to perform an evaluation of the prepared building pad for this project. We understand that the structure will have a monolithic slab-on-grade floor system that will have foundations and a floor slab that will be supported by the newly placed structural fill soils.It appears that between 1.5 and 2.0 feet of structural fill soils have been placed to achieve the desired grades.The intent of our testing was to determine if the newly placed structural fill soils are adequate to provide a hearing capacity of 2,000 psf for the foundations,and have been compacted to 95%to support the floor slab for the new structure. Our evaluation included hand rod probing,advancing hand auger borings with DCPs and performing a density test on the surface. Based upon our hand rod probing the newly placed soils are firm and resistant to significant penetration.Hand auger borings were then advanced at 4 selected location across the building envelope to determine the consistency of the below grade soils.At 12-inch increments in the hand auger boring,to a depth of 3 feet,Dynamic Cone Penetrometer(DCP)Testing was performed In accordance with ASTM STP-399.With proper evaluation,DCP Testing can be correlated to both bearing capacity and percent compaction.Based upon the results of this testing,the below grade soils that will support the foundations and floor slab are acceptable. While on site,our representative also performed in place density testing to confirm compaction of the surface soils.Our testing was performed using the sand cone method in general accordance with ASTM D-155fi.Our results were compared to an in-field proctor that was performed in general accordance with ASTM 0-698.Based upon our tests results,the soils have been properly compacted at the surface. It is important to note that our testing was isolated to the upper 3 feet. As such, we are not able to comment upon the settlement characteristics of deeper soils. Additionally, inclement weather (rain or snow), as well as construction traffic across the pad. can compromise the stability and support characteristics of the surface soils.If the surface soils become compromised,It will be necessary to return to the site for re-testing.This decision should be executed by your onsite Quality Control and Superintendents. 610 Spring Branch Road Dunn,NC 28334 4(inti 11/44-:.7.1A Phone910-292- 2085 Fax 910.292-2192 ..:u.&NNnpandExnh.coin Reviewed By Page 4 of 6 03/20/2018 Field Observations Report Project Name: Lot 84 Cooper Creek CPC(CMT)Spring Project Number: RD180139 Lake,NC Client Name'.
