... Project-Level Issues Project-level issues are those that are specific to the project under consideration and include such items as project size, cost, and schedule, as well as project risk management, risk allocation, and possible certification for sustainable design and construction (e.g., LEED certification)
From page 20...
... Because each of the three main delivery methods (DBB, CMR, and DB) can be applied to projects of all sizes, it seems clear that project size needs to be considered in combination with other issues, such as schedule, agency staffing, and risk management in order to determine an appropriate project delivery method.

... . Many experts believe that DB results Advantages/Disadvantages of Each Project Delivery Method 21
From page 22...
... Early constructor involvement may result in a better understanding of the project risks, and more efficient risk allocation can be achieved. This delivery method is conducive to team work.
From page 23...
... The type of project delivery method selected by an owner will have a profound impact on risk allocation. Some methods allow the owner greater flexibility in allocating risks to the parties involved.
From page 24...
... DBB In DBB, the owner has a clear opportunity to define sustainable design with LEED criteria. The builder's lack of input in DBB means that there will be little opportunity to take advantage 24 A Guidebook for the Evaluation of Project Delivery Methods
From page 25...
... Agency-Level Issues Agency-level issues relate to the owner agency. These will include items such as experience with various delivery methods, workforce requirements, staff capability, agency goals and objectives, agency control of the project, and third-party agreements.
From page 26...
... . The owner's responsibilities in DBB are spread throughout the project (mainly focused on dealing with the designer at the beginning of the process and 26 A Guidebook for the Evaluation of Project Delivery Methods
From page 27...
... DBB Transit agencies have more experience with DBB than other project delivery methods. This experience helps them to gradually build up capability in their staff at all levels of the organization.
From page 28...
... CMR The agency can work with CMR during the design phase and when negotiating the GMP to develop project goals and objectives in alignment with agency goals and ensure that they 28 A Guidebook for the Evaluation of Project Delivery Methods

... This delivery method may encourage a better owner-constructor relationship than DBB, one that can facilitate the achievement of agency goals [Portland Mall Project and Weber County Commuter Rail]
From page 30...
... However, some experiences with DB show that DB contractors have been successful in obtaining responses from project stakeholders by exerting pressure on them. Constructors have different 30 A Guidebook for the Evaluation of Project Delivery Methods
From page 31...
... . Public Policy/Regulatory Issues This section examines the choice of project delivery method in relation to public policy/ regulatory issues such as existing laws, mandated social programs, labor unions, and so forth that establish the legal environment in which the project must be delivered.

... 32 A Guidebook for the Evaluation of Project Delivery Methods
From page 33...
... Issue 16: Federal/State/Local Laws Research done on federal and state laws suggests that transit agencies may not be able to use some project delivery methods. Some states require transit agencies go through several steps before being allowed to use an alternative delivery method.
From page 34...
... . Currently, the FTA accepts all types of project delivery methods; specifically, they modified their evaluation process to accommodate DB and DBOM in the 1990s.
From page 35...
... Lifecycle Issues This section looks at the project delivery methods in a long-term, post-construction context. Lifecycle issues are those issues that impact not only the maintainability of a project and the cost Advantages/Disadvantages of Each Project Delivery Method 35
From page 36...
... CMR The owner of a CMR project can benefit from all the advantages of DBB and also the constructor's advice on maintenance of the end product if the constructor has previously operated similar facilities. DB As quality control is transferred to the design-builder in DB and the details of the design are not known at the time that the project is awarded, many owners have some concerns about the 36 A Guidebook for the Evaluation of Project Delivery Methods
From page 37...
... DBOM This delivery method works much like DB; however, as operation and maintenance are included in the contract and the constructor is in charge of operating the facility after it is built, the owner is less concerned about ensuring the quality and maintainability of the end product. Issue 21: Sustainable Design Goals Sustainable design is becoming ever more important in achieving sustainability goals for projects.
From page 38...
... The effect of various delivery methods on facilitating sustainable construction is the focus of this discussion. DBB With DBB, an experienced constructor does not have the opportunity to give sustainable design features as inputs during the design phase.
From page 39...
... The qualifications-based selection process may reduce the possibility of hiring litigious contractors. DB Some research shows that the size and frequency of change orders are less in DB than in other project delivery methods (Riley, Diller, and Kerr 2005)
From page 40...
... Conclusion This chapter discusses the advantages and disadvantages of various project delivery methods in relation to each of the pertinent issues discussed. It should be noted that in many cases, the advantages and disadvantages listed are not absolute and should be considered in comparison with competing delivery methods.
