5 Past Engineering and Construction Dollars Committed From 2010 to present, DC Water committed more than $2.8 billion for engineering and construction projects in the areas of:Blue Plains upgrades and improvementsCombined sewer overflow (CSO), outfall rehabilitation, and pumping station projectsSanitary pumping facilities and trunk sewer upgradesWater distribution and water facility upgradesWater main and sewer break repair along Spring Place, in Washington, DC.Our Capital Improvement Program (CIP) for the next 10 years is valued at $3.8 billion, and over the next 20 years, $8.4 billion.
6 We Will Work with you!Over the last 3 years (FY 2011 – FY 2013), DC Water has awarded:71 Design, Construction, and CM contracts with an award value of $2.01 billionOf this total, over 33% (or $674 million) was awarded to:Minority Business Enterprises (MBEs), Women Business Enterprises (WBEs), Local Small Business Enterprises (LSBEs), and Certified Business Enterprises (CBEs)MBEs and WBEs have been awarded $584 millionLSBEs and CBEs have been awarded $90 millionFor Design-Build contracts, the prime firms indicated that they will continue to pursue opportunities to exceed the goals of:MBE = 32% and WBE = 6% for construction contractsMBE = 28% and WBE = 4% for A/E contracts
7 MBE and WBE Requirements DC Water’s MBE and WBE Fair Share Objectives are:Objectives are based on goals established by EPA Region 3: DC, DE, MD, PA, VA, & WVDC Water’s policy is to meet or exceed EPA objectives for MBE and WBE participation in prominent and leadership rolesServicesFair Share Objectives (%)MBEWBEProfessional (A/E Agreements)284Construction326Note that some of the projects discussed today may or may not have EPA small business goals. DC Water continues to encourage the use of small businesses.
