z. Construction Contract Amendment with Kraemer North America, LLC for Change Order 2A
for an Amount not to Exceed $1,954,869.81 for the US Highway 85 (Highlands Ranch
Parkway to Dad Clark Gulch) Widening Project, Douglas County Project Number CI
2022-021, CDOT Project Number STU 0852-118 (23474).
Arthur E. Griffith, Transportation CIP Manager — Department of Public Works Engineering
September 20, 2022, Douglas County Board of County Commissioners (BOCC) awarded
Kraemer North America, LLC (KNA) a construction contract for $101,284,008.09 to widen
and reconstruct the section of US 85 between Highlands Ranch Parkway and Dad Clark
Gulch, (located a half mile north of County Line Road). On April 8, 2025, the BOCC
approved Change Order 1A increasing the total contract amount to $106,732,009.90 and
through the most recent progress payment, ending May 25, 2025, KNA has billed the County
$104,706,523.14 and they are substantially complete and approximately 75 days ahead of the
September 29, 2025, required completion date.
As of December 31, 2024, Douglas County has received State and Federal reimbursement
payments totaling $33,223,000 and collected approximately $15,000,000 from the developers
in the Chatfield Basin for this project.
Change Order 2A for $1,954,869.84 represents approximately 1.9% of the original contract
amount; and this change order is required in order for KNA to complete the County’s US 85
project. Most of the additional costs for Change Order 2A is related to utility relocation
delays that required an increase in detour pavement to accommodate additional construction
phasing, ($600,000), the need to maintain a safe construction work zone by providing
additional days of temporary truck mounted mobile impact attenuators, ($185,000), the need
to mitigate poor subgrade conditions (soft spots) at various locations on US 85 within the
project limits, ($685,000) and this change order includes additional concrete pavement for
southbound US 85 south of Highlands Ranch Parkway to improve safety and traffic
operations transitioning from 3 lanes back down to 2 lanes through a combined vertical and
horizontal curved section of US 85, ($485,000).
The funding associated with this Construction Contract Amendment for Change Order 2A
has already been encumbered in Douglas County Purchase Order 2025367, Fund 225, BU
801201.446744 utilizing reimbursement payments received from CDOT in December 2024;
and therefore, no additional funds need to be budgeted for this request.
