Design-Bid-Build (DBB) Construction Manager / General Contractor (CMGC) (Similar to CM at Risk) Design-Build (DB) Design-Build-Operate-Maintain (DBOM) Design-Finance-Build-Operate-Maintain (DFBOM) Build-Operate-Transfer (BOT) Delivery Options: Public Works Projects

Typically led by governmental bodies. Public sector staff oversees project activities, including planning, engineering and construction. Activities proceed sequentially. Project development generally contracted to planning and engineering consultants. Engineering work (PS&E) is completed prior to soliciting construction bids. Construction procurement follows typical low-bid procedures. Generally financed by public taxes, fees or grants. Design-Bid-Build

Involves “alliancing,” a popular project delivery scheme in Australia, UK, etc. Agency contracts with an engineering firm as designer of record. Agency selects a construction manager/general contractor (CM/GC) for the project to provide design input and act as owner’s representative. Agency retains designer and CM/GC, and facilitates a “marriage” for project development. CM/GC and Agency negotiate guaranteed construction price (GMP) as design is finalized. CM/GC completes construction Construction Manager / General Contractor

Planning and conceptual engineering (15%- 35%) completed by agency/consultants. Final design and construction carried out by single contractor, with single contract. Engineering and construction activities proceed in parallel, rather than sequentially. DB bidding may be “low-bid” or “best- value.” Transfers interface risk between design and construction from owner/agency to DB contractor. Design-Build

12
Similar to DB, but contractor is also responsible for operating/maintaining system for specified period in addition to design and construction. Contractor may hold responsibility for procuring and commissioning rolling stock. Provides “implied warranty” between system constructor and system operator. Transfers interface risk between design/ construction and operations/maintenance from agency to contractor. Design-Build-Operate- Maintain
13
Comparison of Delivery Methods: DBOM
14
Similar to DBOM, but contractor arranges and/or provides financing for construction through private capital markets. Contractor typically repaid through “availability payments” or similar mechanism, guaranteed by owner/agency. Transfers financing risk from agency to contractor, in addition to design, construction and operation risk. Design-Finance-Build- Operate-Maintain

Comparison of Delivery Methods: DBFOM
16
Closest method to complete privatization. Agency selects contractor (“concessionaire”) Responsibility for designing, financing, constructing, operating/maintaining system is transferred from agency to concessionaire. Concessionaire may accept revenue risk in addition to DBOM risks. Transfers virtually all risks from owner/agency to private sector. Common delivery method in Europe, Asia, Australia and South America. Build-Operate-Transfer
