Title
CONTRACT NO. K-1314-65: A UTILITY RELOCATION AGREEMENT BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY AND THE OKLAHOMA DEPARTMENT OF TRANSPORTATION (ODOT) FOR RELOCATION OF SEGMENT B WATER LINE LOCATED AT BRIGGS STREET AND SEGMENT C WATER LINE LOCATED AT BROOKS STREET IN CONNECTION WITH THE I-35 WIDENING PROJECT WITH 100% OF THE COST BEING REIMBURSED BY ODOT.
Body
BACKGROUND: As part of the widening of Interstate 35 (I-35), three waterline crossings owned by the Norman Utilities Authority (NUA) must be lowered as directed by the Oklahoma Department of Transportation (ODOT). The relocations are required because the existing waterlines (or portions thereof) are within four vertical feet of a proposed roadway improvement. Generally, this clearance is required to ensure that existing utilities do not impact the roadway construction. Any utility, such as telephone, electric, gas, cable as well as water and sewer utilities operated by the NUA, must be relocated to provide the required clearance.
In February and March 2013, meetings were held with representatives of ODOT and the Department of Public Works to discuss seven potential conflicts between the I-35 project and existing water and sewer utilities. On March 11, ODOT transmitted four letters to the Public Works Department describing potential conflicts with utilities. On June 25, 2013, the NUA was contacted by the Public Works Department and design consultant SAIC regarding the proposed relocation of the existing 24-inch waterline crossing I-35 at Briggs Street. Subsequent discussions with Public Works and SAIC staff revealed the need to also relocate existing 12-inch waterline crossings at Brooks Street/I-35 and at 24th Avenue SW/Highway 9.
DISCUSSION: The I-35 Waterline Relocations project will design and construct the following highway crossings:
1. Waterline A, Highway 9 at 24th Avenue SW: relocate approximately 355 feet of 12-inch waterline with 180 feet of 24-inch steel casing (estimated cost $114,000);
2. Waterline B, I-35 at Briggs: relocate approximately 450 feet of 24-inch waterline with 380 feet of 36-inch steel casing (estimated cost $409,000);
3. Waterline C, I-35 at Brooks: relocate approximately 415 feet of 24-inch waterline with 260 feet of 24-inch steel casing (estimated cost $152,000).
The I-35 Waterline Relocations project (WA0196) was funded in the amount of $675,000 under a separate agenda item. The NUA will design, bid and construct the work illustrated on the I-35 Waterline Relocations Map and be reimbursed by ODOT upon completion. The design will be completed by SAIC under Contract K-1314-66 at an estimated cost of $62,000; $12,000 is attributed to Waterline A at Highway 9/24th Avenue SW and $50,000 is attributed to Waterlines B and C at the Briggs and Brooks crossings of I-35, respectively.
ODOT has requested that the NUA execute and submit the attached Utility Relocation Agreement which sets forth general requirements for performing the relocations and obtaining 100% reimbursement from ODOT. Contract K-1314-65 is for Waterlines B and C estimated at $561,000. Attachment A details the estimated project budget.
RECOMMENDATION: Staff recommends that the NUA approve Utility Relocation Agreement K-1314-65 with the Oklahoma Department of Transportation.
