Engineering Services and HDR first met on October 15, 2014 to discuss potential cost saving measures. At that time, the plans and specifications were substantially complete in accordance with the approved Final Engineering Letter Report. A number of cost saving measures were identified regarding utilities, pavement material, and street section. A second meeting was held on November 12, 2014 to identify which cost savings measures to implement. The street section (surface improvements within the Right-of-Way) decision was put on hold due to upcoming City Council bike lane discussions impacting this, and other, projects. Progress on the other cost saving measures with respect to utilities was also put on hold at this time. The bike lane discussion with City Council stretched through multiple council meetings and into the first quarter of 2015, and culminated with a direction from Council to keep the proposed bike lanes in the street pavement. After the first quarter of 2015, HDR was instructed by Mr. Jerry Shoemaker to proceed with developing and submitting a contract amendment for proceeding with the identified cost saving measures while keeping the bike lanes in the street. Additionally, in July 2015. Mr. Chris Hale arranged for a coordination meeting to be held between the consultants that have street improvement projects that converge at Six-Points to discuss project timing, coordination of improvements, and potential street-scaping improvements at Six-Points. The HDR project team participated in the coordination meeting at City Hall on July 29, 2015, and also participated in subsequent hdrinc.com 555 N.Carancahua,Suite 1600,Corpus Christi,TX 78401-0849 Texas P.E. Firm Registration No.754 (361)696-3300 AMD. NO. 1 EXHIBIT"A" Page 1 of 6 Mr.Jeff Edmonds February 16,2016 Page 2 of 6 meetings with City Staff at the project site to discuss what street-scaping improvements could be utilized. These additional meetings and design changes necessitated further revisions to the contract amendment and, in-turn,further negotiations. Finally, a public meeting was held on November 9, 2015 to present the various street section alternatives to the stakeholders. The overwhelming majority of stakeholders in attendance expressed their preference for the 3- lane section with the off-street cycle tracks and sidewalks. The HDR project team has since been given direction by Mr. Hale to proceed accordingly. The Alameda cost saving measures and design revisions are summarized below: Pavement(Task 1) The City is requesting HDR to modify the plans, specifications, and bid form to accommodate a base bid for asphalt pavement and an alternate bid for rigid pavement. The base bid form and alternate bid form will each contain all associated project bid line items. Water(Task 2) The City requested HDR remove the water stub-outs at the side streets. The stub-outs were intended for future connection when/if the City removes/abandons the existing lines in the rear easements. The proposed waterline in Alameda will remain 12 inches per the Water Master Plan. Wastewater(Task 2) The City is requesting HDR remove the wastewater stub-outs at the side streets. The stub-outs were intended for future connection when/if the City removes/abandons the existing lines in the rear easements. The proposed Cured-in-Place Pipes(CIPP)of the trunk main will remain in the plan set. Gas(Task 2) The City is requesting HDR remove the gas line casings intended for crossings across Alameda Street.This will require close coordination between the contractor and the City Gas Department for installation of new gas lines crossing Alameda.The new gas lines will need to be installed to miss the storm sewers, existing and proposed water lines and the existing sanitary sewer line. Roadway Section and Storm Water(Task 3&4) In general,this modification impacts all roadway and intersection details. The primary revision to the proposed street section is that the bike lanes will be removed from the street 555 N.Carancahua.Suite 1600,Corpus Christi,TX 78401-0849 Texas P.E.Firm Registration No.754 (361)696-3300 AMD.

This will reduce the back-of-curb to back-of-curb width from 54ft to 40ft. One design consideration to be aware of when utilizing a narrower street section, however, is that the existing storm sewer trunk main,which is behind the north-bound curb and gutter, is being kept in place and utilized. Therefore, it is ideal for the new storm drain inlet risers to be installed in approximately the same offset locations as the existing inlets they're replacing. So,with that understanding, by moving the curb and gutter 7ft closer to the centerline, accommodations need to be made to get the storm water from the gutter to the inlet risers. After considering various configurations, HDR proposes utilizing flumes covered with 6in thick reinforced concrete(likely precast)covers to convey the storm water from the gutter to the inlet riser 7ft behind the curb. The addition of the cycle tracks adjoined to the 5ft sidewalks will require specific detailed design efforts in routing them through the corridor with existing encroachments and ramp alignments and configurations at each intersection. These unique ramp configurations will require custom detailed designs not yet seen or utilized in Corpus Christi. Revised Traffic Control Plan and Construction Phasing(Task 5) Due to the pavement reduction width of 14 feet,the traffic control plans will require revisions. The reduced pavement width impacts how much pavement is available for traffic during construction. The following item was initially proposed to be completed as part of this contract amendment; however, it was discussed at the fee negotiation meeting on August 21, 2015 that this item would be eliminated from the contract amendment for the following reasons: • Streetscaping—it was determined that the street layout of Alameda between 6-Points and Clifford Street will remain as originally proposed with only the center raised median being removed. 555 N.Carancahua,Suite 1600.Corpus Christi,TX 78401-0849 Texas P.E.
