Helion Energy Shielding Structure -Foundation February 24, 2023 Helion Energy 3. Action Item 3 (Resolved) — It was noted that the wood forms for the keyway blockouts did not match the geometry per the contract plans. Possible solutions were discussed in field; however, it was agreed that the best solution was to reconstruct the key forms to the geometry shown on the plans.The corrected keyway blockouts had been installed at the time of SO#4 and were in conformance with the plans. See Figure 4. 4. Action Item 4 (Resolved)—At the adjacent building column footing locations, the longer threaded rods with large steel plate washer(6"x 6")was noted to be elevated above the Styrofoam layer,which deviated from detail 4/SF6 of the contract plans, however, PSE finds this acceptable, and no adjustment is required prior to the concrete pour.The change should be documented in the as-built drawings. See Figure S. 5. Action Item 5 (Resolved) — Final covers/protection had not yet been installed in the form savers of the pilaster dowels by S03.Andersen was notified that final efforts should be made to protect exposed threads to ensure ease of installation of the future pilaster reinforcement bars. At SO#4, workers were packing the form savers with foam and duct tape covers.All instances appeared to be resolved. See Figure 6. 6. Action Item 6—Instances of irregular elevation and angle of the pilaster dowels and top of form savers were observed at most of the pilaster locations during SO#3. Some slight inconsistencies in elevation and plumb- ness remained during SO#4. Further review and correction should be made by Andersen to the greatest extent possible prior to the concrete pour to correct the irregularities and ensure ease of installation of the future pilaster reinforcement bars. In particular, instances of form savers at low elevations should not be tolerated. Instances of form savers at elevations slightly above measured grade are acceptable and may be protected with pack grout following the pour. See Figure 7. 7. Action Item 7—One instance was noted in the northwest corner of the foundation where both #5 anchor reinforcing bars were placed on the same side of a cast-in anchor.The bars shall be relocated such that they are on either side of the anchor bar. Andersen was notified of the correction while on site during SO#4 and was working to correct the error. See Figure 8. 8. Out-of-Conformance Item 1 (Resolved)—Outstanding remnants of tie wire and mylar sheets that had fallen to the bottom of the excavated slab area appeared to be sufficiently cleared at the time of SO#4. 9. Out-of-Conformance Item 2 (Resolved)—One instance of a large concrete block noted near the rebar cage region at the SW corner of the foundation, which was noted during SO#3, appeared to be removed at the time of SO#4. 10. Out-of-Conformance Item 3 (Resolved) — One instance of a large steel rod noticed near the middle of the foundation on the south edge, which was noted during SO#3, appeared to be removed at the time of SO#4. 11. Out-of-Conformance Item 4 (Resolved)— Instances of concrete dobies no longer used for maintaining clear cover,which was noted during SO#3, appeared to be removed at the time of SO#4. PAGE 12
