Mountain Street Fayetteville, Arkansas 72701 Attn: Mr. Wade Abernathy Re: Construction Materials Testing and Special Inspections Testing Budget Arts Corridor — Bond & Parking Fayetteville, Arkansas GTS Project No. 22-11017 Mr. Abernathy: This letter is issued as an update to GTS's budget for the above referenced project. The original proposal was issued for GTS's testing and inspection services for $100,780.00. Through GTS's most recent invoice dated November 2022, the total amount billed for this project by GTS is $100,200.74. Additional fees have been accrued since our last invoice in the amount of $42,335.57 bringing the total cost of fees to $142,536.31 to date. A summary concerning the unanticipated overages and anticipated additional fees related to this project is provided below. SUMMARY OF UNANTICIPATED ITEMS The unanticipated increased fees can be attributed to the increased number of site visits requested for technician and engineering staff and added time on site during these site visits during the course of construction. Additionally, additional site visits resulted in sampling of additional test cylinders and performing laboratory tests on concrete specimens due to the increased number of pours. Details regarding these items are outlined on the following pages. Earthwork At the start of construction, the earthwork contractor performed mass site grading operations in very small sections using smaller equipment than what we typically see and experience in commercial earthwork operations. Sections of the building pad were mass site graded in small quadrants before moving to a new section. This ultimately resulted in added trips for our staff to observe conditions and perform density backfill testing. Furthermore, during site grading, several remedial site visits were made to the site by engineering staff due to poor soil conditions and the existing trash fill present on -site at �( undercuts depths. Remedial work associated with portions of the trash fill resulted in undercutting and utilizing geosynthetics and base rock to stabilize the site soils. These items resulted in additional fill material being placed and added density trips to the project site.

Geatechnicat & Testing Services During concrete construction for the columns, the concrete contractor did not have availability of taller column forms at the start of the project. Specifically, the contractor was only pouring 1-3 columns per pour versus the anticipated 6-8 columns. This resulted in increased visits (5 times the budgeted number) to inspect reinforcing steel and perform concrete testing for the ground tier columns and walls as well as the columns located at tiers 2 through 6. Additionally, ground level wall concrete placement pours were conducted in 10 pours versus the budgeted 4 resulting in increased site visits. The added number of trips for concrete testing has resulted in increased trips to retrieve cured cylinders the day after concrete pours and has also resulted in added test specimens. In all, GTS has cast 1,332 test specimens compared to the budgeted 949 cylinders. A summary of the budgeted versus actual pours is presented below in Table 1. Table 1: Budgeted Pours vs Actual Pours per Level for Columns and Walls Areas Level Pours Per Level 27 Budgeted � 5 Overage 22 Level 13 4 9 Level 9 4 5 Level 7 4 3 Level 5 4 1 Level 6 4 2 Ground level walls 10 4 6 Total Pours 50 24 26 PT Slabs Additional trips and time was also incurred for pre -pour post -tension inspections due to incomplete work specifically related to partial installation of reinforcing steel and post -tension cables. GTS performed additional "reinspection" trips after hours (between midnight-2:00 am) immediately prior to concrete pours to observe completed and work corrected items prior to concrete placement. All PT slab pours required reinspections with the exception of 2 placement pours. Added time was spent beyond what was budgeted for stressing operations. GTS observed tensioning device equipment malfunctions and equipment pump issues related to the cold weather. In these instances, stressing occurred a period of several days versus the budgeted 1 Geotechnical Engineering I Construction Materials Testing I Environmental Due Diligence City of Fayetteville Arts Corridor — Bond & Parking Fayetteville, Arkansas GTS Project No. 22-11017 Page 3 of 6 GTS, In c. Geatechnicat & Testing Services day of stressing per slab pour. Additionally, GTS performed 2 additional inspections to observe "lift off' PT cables as directed by the structural engineer to verify recorded elongations. Guardrail Strand Stressin Since late January of 2023, GTS has been observing stressing of the guardrail cabling. GTS has conducted 13 trips resulting in approximately 73 hours of staff time associated with the guard rail stressing. The increased time is due to a number of factors. A quick general summary of several contributing items is presented below: 1) The complexity of the stressing sequence per the shop drawings is much greater than what was anticipated per the structural drawings. GTS notes the shop drawings were not available during developing our initial budget. 2) Added on -site time was required due to the contractor not performing stress sequencing correctly. GTS provided additional oversight and monitoring during stressing operations. 3) Stressing operations extended over a duration of 2 months and resulted in additional trips to complete work. In summary, trips and additional lab testing are presented in Table 2 below. d and Lab Testing Services Density Testing Units Trips Budgeted Quantity 18 • 32 —Overage 14 Proofrolls/Sub rade Evaluation Trips 5 13 8 Reinforcing Steel Inspections Trips 33 57 24 Fresh Concrete Testing Trips 73 123 50 Post Tension Slab Inspections/Tendon Stressing Trips 22 47 25 Concrete Test Cylinders each 949 1,332 383 Guardrail Strand Stressing Hours 40 72.76 32.76 Cancelled Onsite Technician Trips 0 9 9 Cancelled Onsite Engineering Trips 0 6 6 Further, multiple instances have occurred on days GTS was scheduled by the contractor to be onsite for testing or inspections, we were notified by the contractor upon arrival that the testing and or inspections were cancelled. The fees associated with these cancellations were not accounted for in our original proposal are presented in Table 3 below.

GTS Project No. 22-11017 Page 4 of 6 Geatechnica! &Testing Services REMAINING WORK Upon review of the work remaining, GTS estimates the following trips and tests will be required to complete this project as outlined below: Site Work Site work associated with the drives, pavements and hardscapes is incomplete at this time. The following testing is anticipated for these areas: • 7 trips for density testing • Commercial driveway on the west side of the site — 1 trip and 1 set of cylinders • Colonnade Sidewalk — 3 trips and 3 sets of cylinders • Sidewalk along the South Side of Building - 2 trips and 2 sets of cylinders • Curb and Gutter — 3 trips and 3 sets of cylinders • Transformer Pad and Dumpster Pad — 1 trip and 1 set of cylinders • Storm Inlet structures — 2 trips • 8 trips to retrieve cured cylinders on days GTS is not already on -site Based on the above, we estimate a total of $4,700 site work testing associated with the pavements, sidewalks and hardscapes. Stair Towers and CMU Work Construction has recently started at the elevator tower and work is incomplete at the stair tower. We anticipate the following trips related to structural steel inspections and CMU inspections and testing: • North Stair Tower: Structural Steel Observations - 2 trips • South Stair Tower: HSS Weld Connections and Structural Steel Observations - 2 trips • Colonnade Structure: Welded Connections and Structural Steel Observations — 3 trips • South Stair Tower - low -lift -grouting resulting in 3 grout lifts per pour. GTS to inspect rebar prior to grout placement resulting in 7 tiers and the roof level with 24 trips • Estimate 1 set of grout prims per tier — 8 total grout sets • Tier 3 West CMU Walls 4 trips to inspect masonry construction and reinforcing steel • 1 sample of grout obtained for grout prisms Based on the above, we estimate a total of $12,350 for testing and inspections associated with the stair towers.
