O. Box 373 Vail, Colorado 81658 (.lonS(cDgsconw.com) Job No. 112 111 B Subject: Review of Structural Steel Inspection Reports, Millcreek House, Lot 3, Vail Village First Filing, 303 Mill Creek Circle, Vail, Colorado Dear Mr. Stevenson: As requested, we have reviewed the structural steel reports made to date for the subject project. Hepworth-Pawlak Geotechnical is performing construction observation and testing services for the project, submitting our reports under the above job number. The inspection ofthe structural steel connections for the project was performed by West Slope Inspection and Testing (WSTI) as a subcontractor to Hepworth-Pawlak Geotechnical. Doug Young with WSTI, who performed the inspections, is a certified inspector for welded and bolted connections. The structural steel construction is essentially complete at this time. Four inspection reports were�nade for site visits Yo the project by WSTI between October 1, 2013 and March 1, 2014. These reports are attached. The inspections indicate the structural steel connections were made in general wnformance with the project plans and specifications or have been resolved as acceptable by the structural engineer. The structura] engineer (MJ Mueller Company) provided letters regarding the acceptance of non-conforming connections and these letters are also attached. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH — P�I�/-I�AK� ����AL, INC. � � ' s�i ��°e o �� 0 d' � ���. P �a• r. , � David A.

Also inspected higla stren.gth bolting at steel beam, column, and joist connections main level framing. The field welding & lugh strength bolting inspected above appeared to be in general conformance with the plans, and the quality requirements of the AWS Dl .l Structural Welding Code & the AISC/RCSC Specification for A325/A490 bolting except as note beIow. 1) Noticed angle clitps at one side of steel beam to wall embed connections were not weided, as there did not appear to be enougtx room between the s#eel beam & concrete wall to perform the welding. Noticed this condition as noted in report # 1 at basemenUgarage elevator framing Ievel grids 1 to 2.5 & ground level framing grid �/5. Also observed this condition on this visit at ground ievel framing grid C/3 . Steel erectors had welded top flange of steel beams to embed plates with multi pass welds at side were angle clips could not be welded basement/garage elevator framing connections. Top flanges of beams gzound level framing weze not welded Before a final report could be issued some docurnentation would need #o be pxovided regarding this condition as being acceptable or not to the structural engineer. 2) Noticed angie connection clips were not installed/welded at one side of the tube page 2 of 2 steel truss main level framing grid A.8/4. It appeared #hat the wall embed plates were misaIigned with the tube steel huss connections. 3) Noticed or�ly one angle clip was installed/welded at steel beam to wa11 face plate connection main 1eve1 framing grid Cl5.4. Appeared to be a wall pocket too close to beam to weld 2°d angle clip. 4) Some of the steel beam & joists connections had been field welded in lieu of bolting varies locations where bolt holes did not align. Connections had generally been welded three side with 1/4" filtet welds. Have structural engineer review/approve. 5} Welding & bolting was being completed were steel members had been cut loose ground floor framing grid C to D between 1 & 2, and a few bolts needed tightened varies areas. Also beam conzxection clips needed welded main floor fi•aming grid C.2 at 5 .8 & 6.
