<br />CHANGE ORDER SUMMARY <br />Industrial Builders, Inc. <br />WP-42F.1S - Flood Control, 2nd St N, South of Pump Station Add $ 169,490.20 <br />Change Order No. 2 <br />Description: <br />Expose, lift, brace, and move existing fiber lines to allow sheet piling driving, excavation, and construction <br />of box culverts and storm sewer for the 2nd St. N Pump Station outfall. <br />Background: <br />After consideration of several options to relocation the fiber optic line, the recommended option has the <br />least impact to project schedule and the lowest overall cost. <br />Recommendation: <br />The budget of $169,490.20 is less than the remaining estimated unencumbered FY 2015 FMDA <br />Construction budget of $27,090,000. PMC recommends authorization of Change Order No. 2 for <br />$169,490.20. <br /> <br />WORK CHANGE DIRECT SUMMARY <br />Industrial Builders, Inc. WP-42A.2 2nd St N Pump Station Add $ 175,000 <br />Work Change Directive No. 4 <br />Description: <br />The changes in this Work Change Directive include the addition of a baffle wall in the wet well and the <br />addition of vanes in the pump spool between the FSI and the pump (5 pumps). The implementation of the <br />baffle wall will fix issues (identified in the physical model) with vortices in the wet well and improve the <br />flow approach uniformity to the FSI’s. The addition of vanes also improves pump suction velocities. <br />Background: <br />The Wet well physical model study concluded a limited number of modifications are necessary to correct <br />hydraulic flow conditions in the wet wells. Designer of Record (DOR) recently completed design changes <br />and the Contractor provided a Change Proposal that is currently under review. Implementation of DOR’s <br />design modifications is critical to project success and some of the materials have long lead items. Therefore, <br />Owner’s Rep recommends approval of Work Change Directive No. 4 to allow Contractor to order essential <br />materials while Contractor, DOR, and Owner’s Rep finalize Change Order pricing and schedule impacts. <br />Recommendation: <br />The budget of $ 175,000 is less than the remaining estimated unencumbered FY 2015 FMDA Construction <br />budget of $27,090,000. PMC recommends authorization of Work Change Directive No. 4 for $ 175,000. <br /> <br />Recommended_Contracting_Actions_Summary_2015-1008.docx 4
