City of Flagstaff Work Plan for Construction Manager at Risk Contract
Florence-Walnut Railroad Underpass
Federal Transportation Enhancement Project No. TEA-FLA 0(005)A
City of Flagstaff
October 6, 2010
The City of Flagstaff submits this work plan for review and approval for design phase and construction services using a Construction Manager at Risk (CM@Risk) delivery method for the Florence-Walnut Railroad Underpass presented here under the provisions of Special Experimental Project No. 14 (SEP-14) for the use of innovative contracting practices. Both the City of Flagstaff and the State of Arizona approve this contract method as defined in Arizona Revised Statutes, Title 34.
The City of Flagstaff has successfully completed six CM@Risk projects in the past: the Empire Avenue Extension Project, the Alpha Shade Hangers at the City of Flagstaff Pulliam Airport, the Fourth Street Overpass Project, Wildcat Hill Waste Water Treatment Plant Upgrade, Cedar Avenue Bridge and the Aquatic & Multigenerational Center.
General Description of CM@Risk:
CM@Risk is a delivery method wherein the CM@Risk firm participates in the design phase by evaluating cost, schedule, and implications of alternative designs, constructability reviews and value engineering. During construction, the CM@Risk assumes the risk for price based on a Guaranteed Maximum Price (GMP) and schedule. The CM@Risk contracts directly with the trades and subcontractors -and has a single point of responsibility for the delivery of the project.
CM@Risk contractors are chosen on a qualification based selection process, similar to selection of Architectural/Engineering consulting services. The owner advertises for Statements of Qualifications, forms a selection committee and proceeds to evaluate, interview and select the contractor based on qualifications provided.
The advantages of CM@Risk are:
Purpose and Expectations
CM@Risk has been chosen for this project, allowing us to use the contractor's railroad experience and expertise, while minimizing or eliminating construction delays. All of the CM@Risk advantages listed in the prior section will be utilized when working with the BNSF Railway on this unique project.
Recently a City project did require a Contractor to work within the BNSF right-of-way and one difference between the traditional competitive bid process versus a qualification based selection was highlighted. The competitively bid process requires bidding the project and the City Council awarding the project before a contractor starts acquiring the project insurance. Specifically, in the creation of a Quiet Zone in Flagstaff where the BNSF insurance endorsement requirements were emphasized at the pre-bid conference, a smaller contractor competitively bid and subsequently was awarded the project. The Contractor was not able to obtain the BNSF insurance endorsements and the City concurred that the contractor exhausted all practical means to obtain the insurance. The City had to terminate the contract then used a qualification based method to select a contractor that had recent experience working within the BNSF right-of-way.
This work will be within the BNSF right-of-way and the City's previous experience has shown the insurance endorsements required by BNSF cannot be obtained unless the contracting company is of a certain size or has previous work experience within the BNSF right-of-way. The City expectation is by utilizing the qualifications based CM@Risk process to have some certainty that the chosen contractor can obtain the BNSF insurance endorsements.
Project Description and Scope of Work
General Project Description
The underpass is planned for a location just west of downtown, in an area where the BNSF tracks separate two historic neighborhoods; the Townsite neighborhood on the north side and La Plaza Vieja on the south side.
The underpass will be about 50 feet in length, 14 feet in width, and 9 feet in height. The exact length will be determined by BNSF in their design process, and will be long enough to accommodate the planned third track. The width is planned at this time for 14 feet; however the City is exploring whether it is possible to make the tunnel wider to make it more inviting for users.
A short section of concrete trail, about 225 feet in length and 10-12 feet in width, is planned to connect Walnut Street on the north side with Florence Street on the south side through the underpass.
Existing grades are very favorable for an underpass at this location; the tracks are elevated on a berm that is high enough to allow the underpass without lowering the surface of the trail. The running grade of the connecting trail between the two streets will be less than two percent.
The City is considering other amenities to make the facility more inviting, such as hardscaping, seating, and public art.
An updated cost estimate for the underpass is $567,440. The City will fund the $67,440 overmatch through its FUTS program.
Benefits of the underpass
The proposed underpass, as a stand-alone project, will significantly enhance mobility for pedestrians and bicyclists in this area:
Scope of Work
The CM@Risk contractor will begin the project with a design phase services support role to the City. The contractor will work with the designer, through the City Project Manager, to offer value engineering and constructability assessments.
Design phase services by the CM@Risk may include the following:
Prior to construction, the City and the CM@Risk contractor will negotiate a GMP to construct and deliver the project. The CM@Risk will be responsible for construction means and methods, and will be required to solicit bids from pre-qualified subcontractors to perform the work. The CM@Risk is responsible for self-performing a minimum of 45% of the construction work.
Construction phase services by the CM@Risk may include:
The CM@Risk method will include the following sequential phasing:
Phase I - Construction Manager at Risk Selection Process
The Request for Statement of Qualifications (RSOQ) will advertise according to State of Arizona and City of Flagstaff procurement requirements and will include a general description of the project, scope, and project evaluation criteria.
The RSOQ evaluation criteria includes:
Maximum Score = 100 points
The evaluation committee members will score the Statement of Qualifications (SOQ). Upon review of the SOQs, the committee reserves the option of interviewing the three most qualified firms.
After interviews have been completed, the committee will select the most qualifying team to perform as the CM@Risk contractor. After the CM@Risk contractor has been selected, the City and the contractor will prepare the project scope and negotiate a fee for the design phase services and construction services. If an agreement cannot be reached with the first firm selected, the City reserves the right to contact subsequently ranked firms for negotiation to enter into a contract for CM@Risk services.
Phase II - Design Phase Services
Design phase services include the CM@Risk contractor working with the design consultant, through the City's Project Manager, to develop plans, specifications and special provisions. The CM@Risk contractor will also lead the effort for value engineering and constructability reviews during this phase.
Design Phase services will also include:
Phase III - Construction Services
The CM@Risk and the City will negotiate a GMP based on the current design and the CM@Risk estimate for the remaining design features. The primary duties of the CM@Risk during the Construction Phase will be to:
On the following page is a schedule for the completion of the project.
Measures & Reporting
In the City's experience, the CM@Risk process provides innovations in project development, design and construction, and ultimately result in reduced project duration and budget savings. Aside from budget and schedule goals, the emphasis of this process will be on project quality and value.
Two separate reports will serve as important measurements in project delivery. The initial report will describe the selection process for the CM@Risk contractor. This includes the development of the scope, fee negotiation, reactions by the industry if applicable, any innovations proposed by respondents and any major problems encountered and how they were resolved.
The second and final report will be submitted upon completion of the contract and project acceptance by the City. The final report will contain an overall evaluation of the project from the City and the Contractor along with any suggestions and recommendations for improving the process. In addition, the City will discuss the relationship with the Contractor, quality of the final product, number of changes to the original scope of work, additional cost, problems encountered and benefits received. Both reports will be forwarded to FHWA Headquarters.
