BACKGROUND/JUSTIFICATION:
Change Order #3 due to a combination of existing unsuitable subgrade material and receiving consistent
rain during the 2019 construction season a couple of soft areas along the project continue to fail testing.
The contractor has spent considerable time trying to farm and dry both areas in question throughout the
spring and early summer months of the project but the areas are still failing. Project representatives from
the City (Hakanson Anderson), the Contractor (R.L. Larson) and material testing firm (Braun Intertec) met
onsite to review options. Due to project time constraints and unpredictable weather, Braun has provided
a couple of recommended revised street sections to consider.
Hakanson Anderson has discussed the options with Braun Intertec and after review of the costs and
potential for resolving the issues we are recommending that the areas ( —800 feet of Maciver Avenue and
from 800 feet of 85th Street) have the top 7" of subgrade material removed and replace with 3 inch minus
recycled concrete material to proposed finished subgrade elevation. The remaining street section will be
installed as originally planned.
A negotiated unit price for the 3" minus recycled concrete material of $25.25/Ton has been agreed upon.
This unit price includes all costs for delivery and placement of the material. All other unit prices shall be
paid at the contract unit prices. The Change Order #3 is estimated at $108.140.00.
