METRO FLOOD DIVERSION PROJECT <br /> <br /> <br />TAG_CONTRACTINGRECOMMENDATION_MFDA-HMG-TO09A16_2016-1101 1 <br />Technical Advisory Group Recommendation Meeting Date: 11/01/2016 <br />RECOMMENDATION FOR ACTION: <br />The Technical Advisory Group has reviewed and recommends approval of the following Contract Action(s). <br />SUMMARY OF CONTRACTING ACTION: <br />The Owner’s Representative prepared the following Contract Action(s) for the Technical Advisory Group <br />List description of Contract Action(s): <br />HMG <br />MFDA – Task Order 9, Amendment 16 – Hydrology and Hydraulic Modeling $119,426 <br />Add scope and budget for additional subtask K Phase 8 Model Update <br /> <br />BACKGROUND: <br />Houston-Moore Group, LLC (HMG) is the Engineer of Record for the hydrology and hydraulic modeling used to <br />support the design of the proposed flood control improvements. HMG has provided these engineering services <br />under Task Order 9 from June 14, 2012, to the present time. See the table below for a summary of the <br />amendments to the Task Order. <br />The existing scope and budget for Subtask K, Phase 8 Model Update, estimated the level of effort required to <br />complete the Phase 8 modeling but was less than the actual level of effort required for model geometry and <br />hydrograph updates, updates of the historical, tributary, Red River, and extreme event models after recalibration, <br />floodplain mapping of revised model events, updates to the Phase 8 model report, and QA/QC review of the work. <br />This amendment adds scope and budget to subtask K for the actual level of effort required to update the Phase 8 <br />hydrologic models, floodplain maps, and report incorporating the most recent data. <br /> <br />Summary of Contracting History and Current Contract Action: <br />Original <br />Agreement or <br />Amendment <br />Budget ($) <br />Change <br />Original <br />Project Cost <br />Revised <br />Project Cost <br />Project <br />Start <br />Project <br />Completion <br />Comments <br />Task Order 9 <br />Amendment 0 <br />$ - $194,341 $ - 8-Mar-12 30-Sep-12 Initial authorization of subtasks A-F. <br />Task Order 9 <br />Amendment 1 <br />$0 - $194,341 13-Sep-12 30-Nov-12 Added F.I Extreme Rainfall Events, and F.II <br />Extreme Event Evaluations. <br />Task Order 9 <br />Amendment 2 <br />$95,000 - $289,341 14-Sep-12 30-Sep-13 Added F.III Tributary Peak Model Runs to <br />Support the Maple R.
