Design LoadingsBackfill / Ballast Material – Bulk Dry Density assumed to be 16 kN/m3•Minimum allowable soil bearing pressure shall be no less than 80 kPa•Steel Structure Self Weight – 4700 -5700 kg approx.•Tower Reactions (unfactored):•

Vertical (Fz) = 53 kN•Horizontal (Fx) = 51 kN•Moment (My) = 1085 kNm•

The above tower reactions are service loads for the Load Combination 1.0 Dead + 1.0 Wind and are•applied to the buried foundation structure at the base of the tower (Ground Level)

Design Load Combinations.Dead: Tower Self Weight + Steel Structure Self Weight + Backfill Material Self Wt•Wind: Tower Horizontal Reaction + Tower Moment Reaction•Service: 0.9 Dead + 1.35 Wind•Ultimate: 0.9 Dead +1.35 Wind•

Geotechnical InvestigationIt is recommended that a site study be conducted to verify that the soil parameters equal or exceed•the requirements shown above.

Important Note:Please contact ARE directly with questions or concerns, or if just unsure about the aforementioned details and requirements.

Preloaded High Strength Structural boltsThe bolts shall be in accordance with DIN 6914 / ISO 7412.•The bolts shall be installed and preloaded in accordance with BS EN 1090-2:2008 Execution of steel structures and aluminum•structures - Part 2: Technical requirements for steel structures.The slip resistances of the structural bolts were calculated in accordance with EN 1993-8: 2005. It is•understood that the steel will be hot dipped galvanized after fabrication and a bitumen coating willbe applied. The bitumen coating is not suitable on the surface of these joints and therefore it isnecessary to mask the faying areas prior to the application of the bitumen paint.The friction coefficient factor is taken as 0.2 which is recommended for hot dipped galvanized surfaces.•

Preloaded bolt installationThe contact surfaces shall be free from all contaminants, such as oil, dirt or paint.•Burrs that would prevent solid seating of the connecting parts shall be removed.•The preloading force required for an M24 bolt is 198kN and shall be preloaded using the torque control method or other•methods described in EN 1090-2:2008.

Torque control methodIn the torque control method the torque is applied in two steps.•

The first step, after bedding of the joint, is to apply a torque of up to 75% of the required torque value to all the bolts.1.The second step is to apply an additional torque to each bolt such that the total applied to the bolt is up to 110% of2.

the required nominal torque value. The extra 10% is to offset the subsequent torsional relaxation of preload in the connection when the tightening wrench is removed.

Site Control(A) - Earth material shall be excavated 6.3m-sq x 2.1m deep.Excavation walls shall be properly sloped to avoid cave-in.

(B) - Minimum allowable soil bearing capacity shall meet or exceed 80 kPa. Subsoil layer (bearing strata) shall be leveled prior to placing foundation structure in excavated hole. A layer of coarse sand may be used to provide good contact between foundation and compacted subsoil layer.

(C) - Backfill using excavated soil. Backfill material shall be free fromall organic materials and be mechanically compacted in layers not exceeding 250mm. Backfill material must be equal to or exceed a drybulk density of 16 kN/m3.

(D) - Distance from top of kingpost flange to grade shall be 100mm. A slope gradient of 3% to 5% is recommended to mitigate soil saturation andto facilitate runoff away from tower.

Note: For more details and analysis results, refer to the design review report "Direct Burial Foundation System for a Wind Turbine" revB, prepared by JOR Consulting Civil & Structural Engineers.
