Hogan was on site while construction was going on September 11th and 12th, 2019 to inspect lateral lines E-28 through E-24 on the 11th and E-23 through E-19 on the 12th. Trench depth and subgrade elevations were inspected in multiple areas and approved. It was confirmed by DA Hogan that there was 2" below each lateral line pipe per plan. Pea gravel from the pile of aggregate on site was tested and approved per specification. Heavy rainfall hit the site and left standing water and a small layer of soft soil on the subgrade. Since the subgrade was at the correct elevation it was deemed acceptable by DA Hogan to continue with import of base course aggregate. Base course aggregate was collected on site and tested/approved by AESI. In conclusion, all inspections were approved and the lateral lines were constructed per specification/drawings.

Hogan was on site on the week of September 23rd-27th, 2019 to inspect lateral lines W-17 through W-15 on the 23rd, W-14 through W-10 on the 24th, W-9 through W-4 on the 26th, and W-3 through W-1/ E-1 through E-5 on 27th. Trench depth and subgrade elevations were inspected in multiple areas and approved. It was confirmed by DA Hogan that there was 2" below each lateral line pipe per plan. Pea gravel from the pile of aggregate on site was tested and approved per specification. Heavy rainfall hit the site and left standing water and a small layer of soft soil on the subgrade. Subgrade in an area of 9,400 sf in right field of the baseball field is showing minor signs of being unsuitable. Wyser rehabilitated the soil to best of their ability and added geotextile structural fabric (Geogrid tensor TX 160) in between lateral lines W-16/W-15, W-15/W-14, and W- 14/W-13. In are between W-16 and W-13 the base course aggregate will be installed in one 12.2" lift to avoid unnecessary vehicle traffic to protect base integrity. After this addition, the subgrade was at the correct elevation and was deemed acceptable by DA Hogan to continue with import of base course aggregate. Base course aggregate was collected on site and tested/approved by AESI. In conclusion, all inspections were approved and the lateral lines were constructed per specification/drawings.

Geotextile structural fabric (Geogrid tensor TX 160) placed on soil in between laterals W-16 and W-13 to help support soil. 4. After Geogrid was installed lateral lines W-17 through W-10 were now accepted and could start import of base aggregate. D.A. Hogan & Associates, Inc.

A. Hogan Robert Harding, D.A. Hogan DATE: November 13, 2019 KrDA HOGAN RE: Edmonds Woodway High School, Synthetic Turf Conversion Punch List Inspection Substantial Completion Recommendation, Multipurpose Field (Synthetic Turf only) DA Hogan & Associates was on site for an inspection of work in progress on Wednesday, November 13, 2019. The following represents a preliminary punch list inspection for items related to the synthetic turf surfacing. SITE OBSERVATIONS / PUNCH LIST Softball Field 1. Manhole/Nyoplast Catch Basin/Synthetic Turf Cover on left outfield foul line, that lies on top of the detention chamber system, is not installed. Reinstall and provide flush transition. 2. Brush lines straight. This occurs throughout the field, but is more noticeable at the 50-yard line of soccer/football field, and extension of the soccer field mid field line. Pick lines at 50 YL/Mid field line. 3. Buried fibers were found on the soccer midfield line near 2nd base. Untrap fibers at this location and any other areas where fibers may have been glued or sewed down. 4. Multiple seams are visible in the field. Hand pick out fibers to untrap fiber and mask all seams. 5. Quick coupler valve between 3r1 base dugout and bullpen is not flush. Repair to flush condition, consistent with other quick coupler valve boxes. The record above represents the Engineer's understanding of the site conditions observed, discussions held, and decisions made during the visit. Any amendments or revisions to this record should be communicated to D.A. Hogan & Associates within seven days of receipt. D.A. Hogan & Associates, Inc. (206) 285-0400 Tel 119 First Ave. S., Suite 110 (206) 285-0480 Fax Seattle, WA 98104 6. Overall infill levels in the field are inconsistent, with layers of sand, and cork resulting in 1"-1.5" depth of infill (25mm-38mm). Bullpen and batting cage areas have up to same range of infill. Additional infill and/or grooming is required to result in approximately .75"-.50" of exposed fiber. Relevel infill. 7. Remove cork from wall drains in right field. Remove/clean up any cork outside of field. 8. Clean up loose fiber and rock/dirt debris on the field. Maintenance access, in particular, has heavy traffic causing dirt on the turf. 9. Trim J-hooks and long fibers throughout the field. 10. After field is brushed, and infill levels are brought to tolerance (+/- 5mm), this preliminary punch list will be completed in its entirety after additional infill is applied and leveled on the field surface. 11. Document quantities of sand/cork installed. 12. Provide GMAX tests 13. Provide warranty documents and O/M Manual 14. Provide O/M Manual for furnished equipment Photos 1. Install synthetic turf cover on nyoplast MH. Clean rock/dirt debris from synthetic turf. Edmonds Woodway High School Softball Field Field Report November 13, 2019 Page 2 of 5 2. Pick seams to untrap fiber, throughout field. Edmonds Woodway High School Softball Field Field Report November 13, 2019 Page 3 of 5 3. Brush Lines Straight and pick trapped fiber to expose all fibers of lines. 4. Synthetic turf covers at quick coupler valve and Nyoplast CB incomplete, or not flush with adjacent turf. .
