Our services were provided on a part-time basis and included observation of an installed Ufer grounding rod. Results of our site observations are included with this report. On August 27, 2009, a Soilogic field engineer observed the grounding (Ufer) steel placed in the foundation wall for the referenced project prior to concrete placement. The steel observed consisted of one (1) #4 bar approximately 24 inches in length positively tied to the vertical reinforcing steel in the foundation wall located approximately 10 feet west of the southeast corner of the residence and extending above the foundation wall forms in that area.

Box 1608 Fort Collins, Colorado 80522 Attn: Mr. Jason Phillips Re: Reinforcing Steel, Perimeter Drain and Damp Proofing Observations 5621 Evening Primrose Lane (Lot 41-Fossil Lake Ranch 6th Filing) Fort Collins, Colorado Soilogic Project # 09-1014 Mr. Phillips: Soilogic Inc. (Soilogic) personnel have completed the construction observation services you requested for the referenced project. Our services were provided on a part-time basis and included the observation of reinforcing steel placed for footing foundations and foundation walls as well as observation of the installed perimeter drain system and below grade area damp proofing. Results of the completed observation services are included with this report. On August 25, 2009, a Soilogic field engineer observed the horizontal reinforcing steel placed for footing foundations, and perimeter column pads for the referenced residence prior to concrete placement. The reinforcing steel observed for the basement and garage counterfort footing foundations consisted of three (3) #5 bars placed in the longitudinal direction and #4 bars placed in the transverse direction approximately 12 inches on center. The reinforcing steel observed for the perimeter basement column pads consisted of four (4) and five (5) #4 bars placed each way with four (4) #4 bars placed each way for the garage perimeter column pads. Concrete coverage was checked and appeared to meet minimum requirements. At the time of our site visit, the reinforcing steel observed appeared to have been placed in general accordance with the provided construction plans. (Larsen Structural Design project #1342 dated: July 9, 2009.) Digital photographs of the reinforcing steel observed are available upon request.

The reinforcing steel observed for the basement foundation walls consisted of two (2) #4 bars placed continuously at the top and bottom of the walls with #4 horizontal bars placed at approximately 12 inches on center and #4 vertical bars placed at approximately 30 inches on center, tied to the vertical dowels extending from the strip footing foundations. The reinforcing steel observed for the garage stem walls consisted of two (2) #4 bars placed continuously at the top and bottom of the walls with #4 vertical dowels placed at approximately 48 inches on center. The reinforcing steel observed for the counterforts consisted of two (2) hooked #4 horizontal bars at 24 inches on center with two (2) #4 vertical bars at 24 inches on center tied to dowel bars extending from the footing foundations. The reinforcing steel observed for the basement column pads consisted of one (1) pad containing three (3) #4 bars placed each way and two pads containing five (5) #4 bars placed each way. Lap lengths and concrete coverage were checked and appeared to meet minimum requirements. At the time of our site visits, the reinforcing steel observed appeared to have been placed in general accordance with the provided construction plans. (Larsen Structural Design project #1342 dated: July 9, 2009.) Digital photographs of the reinforcing steel observed are available upon request. On September 2, 2009, a Soilogic field engineer observed the installed perimeter drain system and below grade damp proofing for the referenced residence prior to backfilling. The damp proofing consisted of a grey spray -on bituminous coating that appeared to cover all exterior below -grade areas of the foundation walls. The perimeter drain system consisted of rigid 4" perforated HDPE pipe placed at approximate foundation bearing elevation around the exterior perimeter of the basement area of the structure. At the time of our site observation, the perimeter drain system and damp proofing appeared to have been installed in accordance with generally accepted construction practices. 5621 Evening Primrose Lane Fort Collins, Colorado Soilogic # 09-1014 3 We appreciate the opportunity to be of service to you on this project.

Box 1608 Fort Collins, Colorado 80522 Attn: Mr. Jason Phillips Re: Foundation Bearing Observation 5621 Evening Primrose Lane (Lot 41-Fossil Lake Ranch 6lb Filing) Fort Collins, Colorado Soilogic Project # 09-1014 Mr. Phillips: Soilogic, Inc. (Soilogic) personnel have completed the openhole observation you requested for the referenced single family home. The results of our observations are included with this report. On August 21, 2009, Soilogic personnel observed the foundation bearing materials for the footing foundations for the referenced residence. We understand the residence will be a two-story wood frame structure constructed over a full basement. At the time of our field observations, the basement and garage areas had been excavated to approximate foundation -bearing elevation. The exposed material in the garage and basement areas consisted of light brown to brown clayey sand. The clayey sand is consistent with those materials encountered at the time of our geotechnical subsurface exploration report completed for the subject property and outlined in a report dated May 6, 2009. The light brown to brown clayey sand extended to the depth explored of approximately three (3) feet below basement foundation bearing in two (2) completed hand auger borings. Dynamic cone penetrometer tests indicated the clayey sand was medium dense to dense. The clayey sand would be subject to low volume change potential with variation in moisture content at current moisture and density conditions.
