Any deviations or changes have been discussed on site with the appropriate parties and/or the Engineer of Record for the structures in question. A summary of said deviations or changes is listed on page 3 of this document. The evaluations performed for these observations are based on the visible evidence observed at the time of our visit to the site and our application of generally accepted principles of structural engineering. We performed a visual examination only. No material testing, subsurface investigation, or design work has been performed as a part of this submittal. The conclusions and recommendations of this submittal represent our opinion of the existing conditions reviewed in this submittal, and there is no claim, either stated or implied, that all conditions were observed. Clark Reder Engineering, Inc. is not responsible for the conclusions, opinions, or recommendations made by others based on the information included in this submittal or for future changes in conditions. This report is not to be considered a guarantee of condition and no warranty is implied.

Half couplers were stood off from the container with approximately 1-2” of washers and M10 bolts. a. It was noted that some bolts were tightened at an angle other than 90 degrees relative to the container wall. For these locations, it is recommended that the coupler is slid up or down on the truss chord to resolve this angle such that the bolt is perpendicular to the container wall and truss chord. 2. Half couplers were connected to pipes which were then cheeseboroughed to truss chords rather than the half coupler directly attaching to the truss chord. 3. Base header utilized as W8x21 rather than the specified channel. The steel was cut every 10’ for maneuvering. a. W8x21 was beam clamped to half cheeseborough on both sides of the flange. The half cheeseboroughs were then connected to the truss chords. 4. 8’ spans of 20.5” box truss was placed between each vertical. a. The extra spacing resulted in the edge vertical truss legs overhanging approximately 6” from the edge of the container. 5. Horizontal truss legs extend approximately 6” from the downstage edge of container. 6. Wood padding was located on the upstage rung of the bottom truss and upright positions. Upstage padding was not tap screwed to container roof a. Downstage padding was tap screwed to container roof 7. The horizontal pipe on the upstage was not evenly spaced out every 2’ however a 3 pipe per container ratio was maintained. a. Additionally, the amount of connections was doubled to 2 per horizontal 8. Stage left and stage right horizontal pipes were double braced and cantilevered to accommodate vertical truss overhang. 9. Video wall extended above the vertical truss legs approximately 2’ a. 1.5” schedule 40 pipe was cheeseboroughed to truss and cantilevered up to reach video wall attachment point. b. Several of the above-mentioned cantilever supports are absent from some uprights. 10. Screen is tilting slightly back into the container. 11. Containers are located on a bed of crushed 4”-6” rock and leveled. a. Some container corners are elevated above, and not contacting, rock bed. It is recommended to place additional crushed rock in the corner container area such that the entire container base is supported. 12. Some cheeseboroughs are unattached or loose. It is recommended that these cheeseboroughs are attached or tightened.
