I need both VIII and Robyn to attend if possible. 1. Steps Under Ponte – The structural drawings do not match the landscape plans. SP303 shows the steps to be 2-7X1-0 and the L4-34 shows them at 3-0X1-0. The concrete was poured per SP303, but the stone was ordered per L4-34. We need to discuss a new pattern for the stone here that works with the SP303 drawings. 2. Wildlife Observation Decking – L5-01 indicates that the decking pattern is not to be installed in line with the steel framing below. To be honest, I am unsure of what the pattern for the decking is supposed to be. I believe that it would be better if it lined up with the steel framing that it sets on. We need to review and discuss. 3. The railing mock up welding has been redone and needs to be reviewed tomorrow for approval. 4. RFI 64 – We need an answer on this ASAP. 5. We started drilling the piers for the switch back ramp on the north bank on Ponte and it appears that some of the piers are right in the middle of the duct bank feeding Savoye 2 (see SP315 attached). The centerline of the first set of piers should be about 1.8’ east of the VP102 exterior wall. The duct bank centerline should be about 5.7’ east of the VP102 exterior wall. The centerline of the second set of piers should be about 8.5’ east of the VP102 exterior wall. The duct bank encasement should be 2’ wide. There should be a minimum of 1.3’ clearance if the duct bank was installed in the correct location. Can the duct bank location be verified? One other item, has the gas line for VP102 been installed? It was to be adjacent to and follow the duct bank alignment. 6. Olden has stated that the soil on the north bank at Ponte is unsuitable for soil nail walls. We dug a test pit and Kleinfelder has observed and indicated that they agree. We are waiting on the report for this now. That being said, we might need to change this section of wall to cast-in-place, either matching the walls under the bridge (spread footer) or the walls south of the bridge (pier supported). See SP204 attached. Thanks, Eric
