CHANGE ORDER NO. TWO TO CONTRACT K-1516-86: BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY AND JORDAN CONTRACTORS, INC., DECREASING THE CONTRACT AMOUNT BY $161,547.50 FOR A REVISED CONTRACT AMOUNT OF $1,656,492.50 FOR THE WOODCREST INTERCEPTOR PROJECT AND FINAL ACCEPTANCE OF THE PROJECT.
Body
BACKGROUND: The Woodcrest Interceptor improvements were recommended by the Wastewater Master Plan (WWMP), adopted by the Norman Utilities Authority (NUA) in November 2001. The WWMP proposed the enlargement of interceptors to meet obligated and future capacity demands.
The Woodcrest Interceptor Project replaced and upsized the existing interceptor.
