Agenda 03/11/2025 Item #16F 2 (Change Order #6 to #20-7680 for the Pelican Bay Sidewalk Improvements Design)3/11/2025 Item # 16.F.2 ID# 2025-703 Executive Summary Recommendation to ratify administratively approved Change Order No. 6 under Agreement No. 20-7680 for the Pelican Bay Sidewalk Improvement Design with LJA Engineering, Inc. (f/k/a Agnoli, Barber, and Brundage, Inc.), adding $14,747.00 for additional engineering services and 365 additional days during the extended Phase 2 construction period, authorize the Chair to sign the attached change order, and approve the necessary Budget Amendment. (Project 50178) OBJECTIVE: To perform contract administration and engineering services during the extended Phase 2 sidewalk construction project. CONSIDERATIONS: Collier County Ordinance No. 2002-27, as amended, established the Pelican Bay Services Division Municipal Service Taxing and Benefit Unit (the “MSTBU”) of Collier County, Florida, for the purpose of providing street lighting, water management, beach re-nourishment, ambient noise management, extraordinary law enforcement service and beautification, including, but not limited to, recreation facilities, sidewalks, street and median areas. Historically, the Collier County Road and Bridge Maintenance Division (the “Division”) has maintained the asphalt sidewalks in Pelican Bay. Due to aging infrastructure and tree root intrusions, the existing sidewalks originally built in the early 1980’s have reached the end of their useful service life and can no longer be repaired to achieve the desired standards of the Pelican Bay Community. As a result, on behalf of the MSTBU, the Division issued Request for Professional Services No. 20-7680 seeking proposals for professional design services for a sidewalk replacement project on certain public roadways located in Pelican Bay, that ultimately resulted in the Board awarding Agreement No. 20- 7680 (the “Agreement”) to the top ranked firm, Agnoli, Barber & Brundage, Inc. now known as LJA Engineering, Inc. (“LJA”) on April 28, 2020 (Agenda item 16.F.3). The scope of work includes Construction Contract Administration services under Task 6 that require LJA’s services until construction of the Pelican Bay sidewalk improvement project is complete. Construction was implemented in two Phases: Phase 1 of the construction began on June 7, 2021, and was completed on February 21, 2022, and included an approximately 1.3- mile stretch of ADA-compliant sidewalk. Phase 2 construction began on June 6, 2022, and is anticipated to be completed by mid-year 2025, and includes an approximately 11.6-mile stretch of ADA-compliant sidewalk. Staff issued a Notice-To-Proceed to LJA on May 13, 2020, with a Final Completion date of June 17, 2022, a total of 765 days. Five Change Orders have been processed to address unforeseen conditions, increasing the total contract value by $118,643.00 for a revised contract amount of $433,537.00. The project time has increased a total of 900 days to address work included in the change orders, for a contract total duration of 1,665 days ending with completion of Phase 2 construction activities. Change Order No. 6 is a request to increase the value of Agreement No. 20-7680 by $14,747.00 for Task 6, “Construction Contract Administration” to respond to Requests for Information, prepare sketches or revised plan sheets as needed, coordinate with staff and CEI when questions arise or site meetings are needed; and to add 365 days during the extended construction period until the project is complete. This change order ensures that construction of approximately 11.6 miles of pavement in Phase 2 will achieve the desired standards of the Pelican Bay Community by preventing additional delays, future rework, public safety issues and increased liability to the County. This item is consistent with the Collier County strategic plan objective to plan and build public infrastructure and facilities to effectively, efficiently, and sustainably meet the needs of the community. The County’s Procurement Services Division administratively approved Change Order No. 6 as authorized under the Procurement Ordinance, Section Nineteen, Contract Administration, Section 19, Subsection 3.b. This item is consistent with the Collier County strategic plan objective to plan and build public infrastructure and facilities to effectively, efficiently, and sustainably meet the needs of our community. FISCAL IMPACT: Change Order 6 increases the overall contract by $14,747.00 for a total contract value of Page 3049 of 4027 3/11/2025 Item # 16.F.2 ID# 2025-703 $448,284.00. A budget amendment is necessary to transfer $14,747.00 from Pelican Bay Services Division Operating Fund (1007) to Landscape & Irrigation Capital Fund (3041), Pelican Bay Sidewalk Maintenance/Enhancement Project 50178. GROWTH MANAGEMENT IMPACT: This project meets current Growth Management Plan standards to ensure the adequacy and availability of viable public facilities and to remain in compliance with all regulatory programs. LEGAL CONSIDERATIONS: This item is approved as to form and legality and requires majority vote for Board approval. —SRT RECOMMENDATIONS: Recommendation to ratify administratively approved Change Order No. 6 under Agreement No. 20-7680 for the Pelican Bay Sidewalk Improvement Design with LJA Engineering, Inc., adding $14,747.00 for additional engineering services and 365 additional days during the extended Phase 2 construction period, authorize the Chair to sign the attached change order, and approve the necessary Budget Amendment.
