WHEREAS, the Mountain Lakes Red Trail bridge is a historic stone arch bridge dating to the time of the Princeton Ice Company’s operations between 1884 and the 1920s; and
WHEREAS, the bridge was determined to be in a significant state of disrepair and, in 2021, an application was made to the New Jersey Historic Trust for a grant to offset the cost of the work required for rehabilitation; and
WHEREAS, the New Jersey Historic Trust awarded a grant of $395,218.00 to Princeton to effect the rehabilitation of the Red Trail stone arch bridge; and
WHEREAS, designs for the rehabilitation of the Red Trail bridge and replacement of the Green Trail bridge were completed and bids were solicited and received in 2025: and
WHEREAS, by Resolution 25-138 adopted on April 14, 2025, Princeton Council awarded a contract to Colonnelli Brothers, Inc. for the Rehabilitation/Replacement of Two Pedestrian Footbridges in the Mountain Lakes Preserve for an amount not to exceed $947,200.00; and
WHEREAS, upon commencement of work and dismantling of the bridge it was discovered that the stone arch and the wingwall footings were in a condition that was unforeseen at the time of design, including large stones protruding vertically above the stone arch and footings that were no longer in alignment to facilitate reconstruction of the wingwalls; and
WHEREAS, in order to fully evaluate the conditions, redesign the arch and new footings, and negotiate additional costs, Princeton suspended the work and Colonnelli Brothers, Inc. demobilized for the duration of the suspension; and
WHEREAS, negotiations between Princeton and Colonnelli Brothers, Inc., in good faith, resulted in a compromise of a reasonable cost to complete the additional work of remobilizing, demolition of the existing footings, forming and constructing new reinforced concrete footings, and constructing a modified reinforced concrete arch relief slab; and
WHEREAS, the negotiated cost of this construction due to unforeseen conditions is $314,670.00, which is an increase of 33.221% of the original contract total, resulting in a new not-to-exceed construction contract amount of $1,261,870.00; and
WHEREAS, Princeton has complied with the requirements of N.J.S.A. 40A:11-16.7 et seq. regarding changed conditions for construction contracts and N.J.A.C. 5:30-11.9 et seq regarding the approval process for change orders which exceed the 20 percent limitation; and
WHEREAS, Princeton Engineering staff recommend authorizing Change Order #1 to Colonnelli Brothers Inc. in the amount of $314,670.00 and an extension of time to complete the work of 120 days;
NOW, THERFORE, BE IT RESOLVED by the Council of the Municipality of Princeton, County of Mercer, State of New Jersey, as follows
