The project consisted of the construction of a 150' monopole telecommunications tower at 1010 Aldrin Drive in Eagan, Minnesota. Edge Consulting personnel arrived on -site to inspect the caisson foundation excavation and inventory the structural reinforcement steel. It was found that all reinforcement steel was in general accordance with ATC's tower foundation plans, and the soils generally matched the geotechnical report prepared by Pinnacle Engineering. Concrete for the tower foundation was supplied by Cemstone. One set of five concrete test cylinders was cast in total by Edge Consulting Engineers for the tower caisson foundation, and Soils and Engineering Services (SES) reported that the 28 -day compressive strength requirement of 4,000 psi was achieved. Scope of Work: • Check soil conditions for general compliance with the geotechnical report. (Soil type, depth, groundwater depth, etc.) • Check overall excavation dimensions for general compliance with plans. • Check reinforcing steel for proper quantity and placement • Check for proper concrete cover on reinforcing steel • Cast five (5) concrete cylinders for compression testing at each pour location Edge will also attempt to spot check various other items such as the anchor bolt height, use of bonding agent, placement of bolt cage within the pier, etc. However, limited time will be available and it should be understood that the contractor is still the guarantor of the work and Neil_ Armstrong _(274262)_Foundation_Report 1 of 2 9/03/2010 responsible to construct the foundation according to applicable plans, specifications and standards. Limitations: • Due to inaccessible nature of the caisson foundation excavation, soil conditions and bearing capacity at the base of excavation could not be effectively verified.

The contractor had the rebar cage tied and finished drilling the caisson foundation and were ready to install concrete the next morning. 8/6/10 Edge Consulting arrived on site in the morning. The contractor had finished drilling the caisson Field Report No. 1 foundation the previous day. The rebar cage was inserted into the caisson foundation and was held up off the base with chains connected to the drill rig then released once enough concrete was poured to hold the rebar cage. No groundwater was encountered so there was no need to flood and add slurry to the excavated caisson foundation. The contractor had put casing in the entire length of the drilled foundation to maintain the side walls. 8/6/10 The drilled caisson foundation had been drilled to specified depth, casings inserted to maintain the sidewalls; the rebar cage installed, and concrete installed. By the end of the day the contractor had removed all casings and installed concrete. Once the concrete neared the top of the foundation the reveal was set, leveled and anchor bolts positioned on top of the reveal with approx. 12'/4" of bolts being exposed. The excavation of the drilled tower foundation was advanced using conventional excavating techniques. Soils encountered generally matched the geotechnical report and consist of grayish brown sitly, sandy soils with a little clay; trace gravel and cobbles. No groundwater was encountered. The rebar for the tower foundation was inventoried at the time of the inspection. The inventory was based on visual observations and all rebar installed was in general accordance with American Towers foundation plans. (5) Five concrete test cylinders were cast in total. The contractor ordered and poured a 5,000 psi concrete mix from Cemstone. The cylinders were stored on site until concrete was set. A slump test was also performed for quality verification and was found to be adequate. The concrete test cylinders will be scheduled for pickup and compression testing at a later date.

The tower site is located off of Aldrin Drive within the City of Eagan, Minnesota. An existing asphalt parking lot provides access to the compound. 1.2 Purpose of Report The purpose of this report is to provide information regarding observations made by Edge Consulting Engineers, Inc. at the point of substantial completion. A visual review of the tower installation was completed. Items which did not match tower and site construction plans or standard installation practices have been noted. If applicable, a recommendation for correction has been provided. 1.3 Scope of Work The above noted tower was inspected following the general guidelines outlined in the most recent EIA /TIA standard (EIA /TIA - 222 -G). Specifications outlined in Sabre's Tower Erection Drawings were also observed. This inspection will serve to satisfy the special inspection requirements of the Minnesota State Building Code (Section 1305). A tower climb was completed by Edge Consulting personnel. The climber ascended & descended the tower along the fixed safety climb and a visual inspection of the tower was performed from this vantage point. Many assessment items noted are based on a general visual inspection completed during the tower climb. However, it is not within the scope of work to physically check or closely observe every member, bolt, connection, etc. • Tower Members o Visually checked for obviously bent, missing, or loose members on the tower. Any bent, missing, or loose members which are observed will be photographed and the approximate height will be documented. o Checked for any loose or missing bolts on the tower. While climbing the tower personnel visually inspected connections for obviously loose bolts. Any missing or loose bolts have been photographed. o Checked existing climbing facilities and platforms (specific carrier) to be sure they were secure. • Tower Finish o Visually inspected the overall paint and /or galvanizing condition during the tower climb. Areas of obvious rusting or chipping have been noted and photographed. • Tower Lighting (If applicable) o Visually inspected conduits, junction boxes, and fasteners to see if they were weather tight and secure. Obvious defects in the wiring condition have been noted. Finally, any obvious signs that a light is not functioning correctly have been reported. Neil Armstrong Tower Inspection 9/30/2010 • Tower Base Foundation o Visually observed the above ground portion of the tower foundation for obvious signs of settlement or movement. Excessive erosion around the foundation has been noted (if present). Finally, it will be noted if standing water is observed in the vicinity of the tower foundation. o Visually checked that all nuts and lock nuts at the tower base are secure and tight. If grouting is required, the grout condition will be noted. Finally, the condition of the concrete above grade has been observed for signs of cracking and spalling. • Tower Profile o Edge Consulting personnel has prepared a tower profile that contains the following information: • Antenna and Feed line ■ Elevation • Type • Size • Manufacturer • Connectors and hangers • Walkways, platforms, floodlights, etc. • Elevation • Arrangement • Antenna Installation (If applicable) o For the specific carrier, Edge personnel visually inspected the antenna elevation and noted if any of the following were identified: • Members - bent, broken, loose and /or missing bolts • Elements - bent, broken, loose and /or missing bolts • Corrosion condition • Feed Lines • Hanger condition, quality, corrosion • Flanges and seals • Line condition - Dents, abrasions, holes, leaks, jacket condition ■ Grounds Leads - Bonded both ends • Ground Kits - Secure, weather tight 1.4 Limitations and Exceptions It should be understood that the contractor is still the guarantor of the work and responsible to construct the tower site according to applicable plans, specifications, and standards.
