Transportation Committee
FROM: Bob Giberson, Public Works Director.
BY: Dave Sorensen, Project Manager
DATE: April 25, 2014
SUBJECT: Cascade View Safe Routes to School
Project No. 91210301, Contract No. 13 -043
Supplemental Agreement No. 3
ISSUE
Execute Contract Supplemental Agreement No. 3 with David Evans and Associates, Inc. to provide a contract time
extension and cost increase for design services for the Cascade View Safe Routes to School Project.
BACKGROUND
The design services contract for $38,783 with David Evans Associates for the Cascade View Safe Routes to School Project
began February 21, 2013 and will expire June 1, 2014. Supplement No. 1 was for additional Right -of Way work and
Supplement No. 2 was for a time extension only. Supplement No. 3 is needed for additional time to complete the right -of-
way negotiations and subsequently design services costs have also increased for this Safe Routes to School Project.
DISCUSSION
The design contract warrants additional funds for the added design expense for the following reasons:
• Expanded scope of the drainage system and performing underground utility locates within the project area.
• Adding Historical Research Associates to develop an Archeological Monitoring Plan and assist with Tribal
Consultation. This plan was required by the Washington State Department of Historical Preservation as a condition
of our Project's 05 -05 approval. Without this approval the project cannot move forward.
• Redesign of the trail to provide more separation from the cemetery parcel.
• Adding bid assistance by David Evans Associates, Inc. during the bidding process.
FINANCIAL IMPACT
The cost negotiated for this increase with David Evans Associates, Inc. for $24,075.00 is reasonable for the size and scope
of this project and is within budget.
Contract Budget
Design Contract $38,783.00 $84,000.00
Additional Design Work (Supp. No. 3) 24,075.00 0.00
Right -of -Way (Supplement No. 1) 25.675.00 78,000.00
Totals $88,533.00 $162,000.00
The remaining design budget is intended to be used to meet the education /encouragement component of the grant award.
RECOMMENDATION
Council is being asked to approve Supplemental Agreement No. 3 to Contract No. 13 -029 in the amount of $24,075.00 with
David Evans and Associates for the Cascade View Safe Routes to School Project and consider this item on the Consent
Agenda at the May 5, 2014 Regular Meeting.
