Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

17 FUNCTIONAL AREA DEFINITION The design functional area receives inputs from the planning function for the purposes of producing the scope of the planned facility and deciding final parameters and ele- ments from the alternatives input. At NYSDOT this includes 3D design models, specifications, and contract documents including bid and proposal documents that are passed for- ward to the procurement function. DESIGN FUNCTION DELIVERABLES Responses to the survey questionnaire revealed the deliver- able types or datasets shown in Table 5 as being received, processed, or sent through the design functional area. Responses are indicated by two numbers: response count fol- lowed by percentage of total responses for the functional area. ADVANCED PROCESSES NYSDOT performs a best practice in the design functional area by creating a 3D design model of the project. This practice is efficient as it serves two main purposes that reduce input procedures and efforts internally, externally, and across the project life cycle. • Internally: The 3D design model is passed to the pro- curement, construction, and O&M functional areas where design data are extracted for the deliverables in those functional areas, thereby reducing redundant resource input and increasing accuracy within the organization. • Externally: The 3D design model is shared with the contractor, allowing technology-savvy individuals to perform virtual construction [4D (three dimensions plus construction project scheduling) CAD scheduling and virtual reality constructability review] and 5D (three dimensions plus construction project estimate) CAD estimating, thereby reducing redundant resource input and increasing accuracy within the external proj- ect organizations. • Life cycle: The 3D design model acts as the shell for a 3D design model that can follow the project’s life- cycle stages, acting as an information repository by allowing input and extraction of data throughout the project’s life. FDOT performs advanced processes in the design func- tional area as follows: • The development of a project compact disc (CD) contain- ing all the design documents and deliverables required for their electronic bid letting process. • As the CD gets processed between the design and pro- curement functional areas, their process enables checks for completeness, compliance with statutes and direc- tives, versioning, and QA. Case Study #1 NYS DOT • Work-Flow Process Diagram. Figure 6 (page 14) shows a data work-flow diagram for design functional area. • Software Applications Utilized. Table 6 displays the software applications and data formats extracted from the IDEF0 diagram for NYSDOT design functional area (see Figure 8). • Hardware and Networks. Microsoft Windows 2003 Server networks are utilized. • Challenges and Process Adjustments. The NYSDOT reported the following barriers and challenges to advanced processes implementation: – Justification of efficient process change compared with cheaper, but less efficient, processes. – Development of functional area culture or mindsets to make efficiency changes, specifically 3D design and modeling. – Proprietary file formats that prevent efficient data exchange between software applications, specifically in regard to DTMs. Case Study #2 FDOT • Work-Flow Process Diagram. Figure 9 shows a data work-flow diagram for design functional area. • Software Applications Utilized. Table 7 displays the software applications and data formats extracted from the IDEF0 diagram for FDOT design functional area. • Hardware and Networks. Linux and Microsoft Win- dows 2003 Server Networks are utilized. • Challenges and Process Adjustments. FDOT reported the following barrier and challenge to advanced processes implementation: – State statute required for electronic signature substitute for engineer’s plan stamp.
