Daily align with QA Team discussing upcoming walks and FOKs. Went over specs per FOK and upcoming walks in GSEF1, GSEF2, CMDF 1, CMDF 2. Met with our FE team at RPL10 and completed a walk through for each room. Verified spacing in between ladder racks support and worked with FE team to have it corrected. Verified splicing, cable management, and routing. Verified cleared issue #6394 in CMDF1. Created checklist with FE team to prepare for the 100% walk.

Created L1 checklist for 45 different shipments to the warehouse. Met with Meta, DPR, and other GCs for 11am to discuss upcoming weekly Wednesday walks with needed personnel to better align our scheduling and progress. Qa Team meeting discussing IES QA/QC Workflow Process.

Walked CMDF2 and took measurements to ensure that the racks placed were at the correct locations before being anchored. Racks were landed according to prints. Super Chance informed us about issues he noticed in the field, took pictures and created formal issues in ACC, listed below: Issue #6395 GSIDFNX05 MOFE Door Issue #6393 GSIDFNX05 Labeling Conflict Richard reviewed splice cassette alignment with chance to ensure that they were aligned with the FE labels Walked the GSIDFNX05 and noticed that Clear Core left fiber clippings on the floor and that the fiber dressing in both the 432 can and the 1u unican fiber enclosure was not up to standard, they were called back to correct the dressing.

Completed a field walk with the FE team through the GSEF's 1/2, CMDF 1/2, and IDFNX5. Photos of the temporary 2 post rack in GSEF 1 for the temporary splices were taken. Temp splices of two 192 fibers in IDFNX5 were completed by Clear Core. SFE Paul informed us that the horizontal ladder runway in both CMDF's will have to move away from their respective walls by approx. 5" to allow for adequate space for the fiber to be routed within the bend radius. The changes will be redlined after installation per Hargis. This will also allow for the horizontal crossovers to be installed with out the overhead support. As the CMDF's have been buildout to spec, the FE's are reviewing to see if this will be a change order.
