A IFO A DALY COMPANY January 11, 2019 Mr. Jeff H. Edmonds, P.E. Director of Engineering Services City of Corpus Christi 1201 Leopard Street Corpus Christi, Texas 78401 Reference: Amendment 4 to Bond 2014 Proposition 2 - Ayers Street— SPID to Gollihar (Project No. E15106) Dear Mr. Edmonds: LAN respectfully requests that the City consider an amendment to our professional services agreement for the Ayers Street Pedestrian and Turn-Lane Improvements Project (E15106). The purpose of this amendment is to increase our compensation for additional bid phase services to evaluate and include an additive alternate related to the proposed paving improvements. Proposed Additive Alternate In November 2018, LAN met with City staff to discuss and respond to contractor questions prior to the bid date. These recent questions and previous contractor questions created concern that some contractors would not bid the project, or the bids would come in over budget due to the multifaceted pavement design. City staff asked for LAN's opinion on whether a redesign of the project for full depth reconstruction would result in more competitive bids and within the available budget. On December 13, 2018, LAN sent a letter summarizing that the as-bid design met the intent and criteria of the Bond project and is constructible but benefits from a full depth reconstruction (FDR) outweigh the negatives and may avoid potential cost overruns for unforeseen conditions. LAN recommended that the City reconsider FDR of the entire roadway within the limits of this project. On December 170, 2018, LAN met with City Engineering staff to discuss the above recommendations and agreed that before considering a redesign of the project, the project could be bid including an additive alternate that would allow the contractor to provide the unit costs for completing additional pavement reconstruction up to a full-depth reconstruction of the roadway where necessary. Scope of Amendment #4—Additional Bid Phase Services As mentioned above, LAN will include an additive alternate in the bid documents for the prospective contractors to include unit costs for completing additional pavement reconstruction up to the full depth reconstruction of the roadway. In order for us to revise our bid documents we need to do the following additional items not included in our original contract or previous amendments: 500 N.Shoreline Blvd,Suite 905 • Corpus Christi,Texas 78401 • 361.882.2257 • www.lan-inc.com AMEND. NO. 4 EXHIBIT "A" Page 1 of 4 Bond 2014 Proposition 2-Ayers Street(El 5106) Amendment 4 January 11,2019 Page 2 • Provide an exhibit and coordinate with a third-party geotechnical engineer to complete additional borings of the roadway. • Review the recommendations from the geotechnical engineer and analyze the borings and existing pavement strata. • In AutoCAD Civil 3D, generate additional cross sections of the existing and proposed roadway surfaces, analyze those cross sections, perform paving quantity take-offs, and revise the proposed surfaces as necessary. Additional cross sections will be included on approximately ten (10) new sheets included in the Addenda. • Based on the results of the additional geotechnical work and the additional cross sections, generate new concrete pavement demo details (this may be more than one detail depending on the Geotech and limits of existing pavement) and complete additional concrete pavement quantity take-offs, as necessary. • Revise/firm-up existing as-bid drawings to reflect the paving materials/limits, discovered through the above analysis, and include those revised sheets in the proposed Addenda. Drawings that will need to be revised include: o Drawing Index o General Notes (2 sheets) o Estimated Quantities (2 sheets) o Demolition and Removal Plans (10 sheets) o Limits of New Improvements &Overlay Plans (2 sheets) o Street Plan &Profiles (8 Sheets) • Modify bid form and front end documents. The following front end documents will need to be revised to reflect the additive alternate: o Table of Contents o Invitation to Bid and Instructions to Bidders o Bid Acknowledgement Form o Bid Form o Supplementary Conditions o Summary of Work o Alternates and Allowances o Measurement and Basis of Payment o Special Procedures • Modify the Opinion of Probable Construction Costs • Attend an additional pre-bid meeting, including pre/post discussions with City staff, review/respond to additional Bidder questions, prepare Addenda, and review bids, revise bid tabs to include new pay items, and provide recommendation for award. Summary LAN understands that this project is unique and has promised to deliver a project that is both complete and constructible. For that reason, we anticipate that we will require more fee to complete this additional scope of work during the bid phase. We respectfully request that the City consider an amendment to our professional services agreement for the Ayers Street Pedestrian and Turn-Lane Improvements Project(E15106). LAN AMEND. NO. 4 EXHIBIT "A" Page 2 of 4 Bond 2014 Proposition 2 -Ayers Street(E15106) Amendment 4 January 11, 2019 Page 3 is proposing a total additional fee of$31,745.00 for Amendment #4, a total restated contract fee of$661,975.00.
