(GTO) has visited the above referenced project site on several occasions to check the soil subgrade conditions and backfill in the Drillers Lane road extension area for the shop building under construction. Observations included the stability of the proposed subgrade under dynamic loading (proofroll) for the entire length of the road extension, as well as compaction testing in general accordance with Virginia Department of Transportation requirements. Our staff has exercised the degree of care normally associated with a project of this type. All inspections were performed in general accordance with 2012 IBC Section 1704 requirements for special inspections. A fully -loaded, pneumatic -tired tandem axle dump truck was observed on -site at proposed subgrade elevations and stone base elevations to proofroll the proposed roadway. Minimal deflection and rutting within this cut to grade subgrade section of the proposed roadway was observed. This observation indicates an acceptable condition for the roadway subgrade. GTO personnel checked the in -place density of the soil subgrade. The subgrade soils were checked by our laboratory for maximum dry density. In addition, field density testing using nuclear methods (ASTM D2922) were performed to check backfill placement. Test results indicate soil subgrade as of March 25r^, 2019 appears to conform to project specifications with regards to in -place density.

(GTO) has visited the above referenced project site to check as -constructed conditions of the extension of Drillers Lane under construction. Roadways checked as part of this project include the new Drillers Lane extension that was being constructed during our site visit on March 26th, 20196. GTO obtained one subgrade at previously un-sampled areas and returned it to our laboratory for subgrade stability analysis in general accordance with VTM-8 (California Bearing Ratio). Our staff has exercised the degree of care normally associated with a project of this type. All inspections were performed in general accordance with 2012 IBCSection 1704 requirements for special inspections and Virginia Department of Transportation samplingand testing requirements. Test results indicatethe subgrade soils within the aforementioned section of roadway, when properly compacted to Virginia Department of Transportation requirements for subgrade soils, do have an average CBR value of 5, which should be adequate for use in design of the roadway pavement structure for the short road extension.

(GTO) has visited the above referenced project site on April 12t^, 2019 to check stone base compaction on the roadway extension for the existing Drillers Lane at the new building construction. Testing was performed in general accordance with Virginia Department of Transportation requirements. Our staff has exercised the degree of care normally associated with a project of this type. On April 12N, 2019, GTO personnel observed the stone base already placed. The stone subbase area was proofrolled using the available fully loaded, tandem axle on -road dump trucks delivering stone to the site and observed by GTO personnel. In addition, thickness was checked at the proposed compaction test locations and was found to be in excess of eight inches at every location. The area appeared to be stable and sufficiently prepared to test for in -place density. GTO personnel checked the stone base placement. The Virginia 21A stone was tested for maximum dry density using the one -point proctor method (VTM-12), resulting in a weight of 144.9 pounds per cubic foot at an optimum moisture of 7.8 percent, requiring an in -place density of at least 137.7 pounds per cubic foot. In addition, field density testing using nuclear methods (ASTM D2922) were performed to check backfill placement. Test results indicate stone base as of April 12m, 20198 appears to conform to project specifications with regards to in -place density.

Box 260 Earlysville, Virginia 22936 RE: Asphalt Testing Foster Well and Pump Shop Building COT Albemarle County, Virginia GTO Project No.: 18G-265-070 Dear Mr. Foster: As requested, an engineering representative of Geo-Terrain Organization, Inc. (GTO) has visited the above referenced project site on several occasions to check asphalt compaction on the intermediate base and surface topping course on the extension of Drillers Lane. Testing was performed in general accordance with Virginia Department of Transportation requirements. Our staff has exercised the degree of care normally associated with a project of this type. The fresh hot mix asphalt was checked for temperature and was measured to be 277 degrees Fahrenheit for the intermediate course, and 295 degrees Fahrenheit for the surface course. A short roller pattern established at the outset of the project indicated six passes of the smooth drum roller is satisfactory for compaction of the IM-19.0 intermediate base course, and seven passesforthe SM-9.5A topping course. A short control strip was performed using the recommended six passes of the roller to establish the maximum in -place asphalt density of 143.5 pounds per cubic foot (pcf) for the intermediate course, requiring a minimum passing test to achieve a density of at least 136.3 pcf. Likewise, the same was performed for the surface course using the recommended seven passes, establishing a maximum in - place asphalt density of 140.4 pounds per cubicfoot (pcf), requiringa minimum passingtestto achieve a density of at least 133.4 pcf. Tests were performed every 50 lineal feet of roadway in the extension. Based upon observed results, it appears the asphalt was placed and compacted in general accordance with VDOT requirements. Please seethe field test results listed below for additional information. ➢ Intermediate course, 50 feet from existing pavement, density 141.2 pcf ➢ Intermediate course,100 feet from existing pavement, density 140.6 pcf ➢ Surface course, 50 feet from existing pavement, density 138.6 pcf ➢ Surface course, 100 feet from existing pavement, density 137.2 pcf Thank you for the opportunity to assist you in this capacity.
