Introduction
According to NEPA, the selected items should be determined as classified exclusion items (CE) or found to have no significant impact. In addition, it is expected to reduce problems with usage rights and utilities. KYTC surveyed many states engaged in design or, reviewed and construction AASHTO materials associated to design and construction as component of the development of primary processes. KYTC is paying attention in collecting information and data about the execution performance of primary design and construction project.

Design-Bid-Build Project Delivery
Before starting a project, designing and constructing buildings, bridges, or any type of improvement method is an important consideration because it can have aN important impact on costs, risks, moreover overall progress (Abdelrahman Youssef, 2017). The following sections explain the most common categories of the project delivery techniques.
Once the bid is chosen, owners establish a agreement with the selected contractor or starts work on project. As a traditional method of the projects delivery, the DBB technique is usually the very familiar method in the business. The traditional form of the construction project delivery is DBB. The common methods of DBB are as follows:
1) The owner appoints a designer to create the plan and specifications of the project, or completes the design in-house;
2) After the design is completed, then project is subscribed;
3) Once the contractor is chosen, then project is build.
For projects that use DBB delivery technique, design is totally completed before contractor bids for the project. Other feature of DBB delivery technique is that there has been a little communication among the different parties that have traditionally been involved.
Comparison of Design-Bid-Build and Design/Build
One of the differences between DBB and DB is the order of project phases. DBB is end-to-end. Conceptual planning is primary stage, followed by preliminary design, engineer selection, project approval and final design, contractor selection, as well as final construction. Before the beginning of the next phase, each phase is completed in order. Using DB can save time because construction overlaps with project approval and final design, or there is no separate selection procedure for designers / engineers (Minchin, Li, Issa and Vargas, 2013). The overlapping levels in the DB allow the design to be finished during construction. Time saving is the foreseeable benefits of DB delivery, as well as many other organizations have documented proof of time saving. Compared to the DBB agenda for the similar project, DB projects completed under the Federal Highway Administration's SEP-14 procedure show a standard time savings of 14%. In addition, the Florida Department of Transportation’s top 11 DB projects saved 37% of their time. Table 1.1 below emphasizes the differences in roles and responsibilities of various parties between DB and DBB project delivery. Through DB delivery, the initial cost of the agent can be saved. With the DBB delivery, design can be completed before construction starts. Nevertheless, as mentioned earlier, the database project has not completed the intensive preliminary design. Hence, the first costs related with the database are restricted to the proposal application (RFP) creation, historical soil data collection, primary design, bid analysis, moreover possible subsidy costs (Sullivan, Asmar, Chalhoub and Obeid, 2017). Another benefit of database delivery is that a agenda can be determined early in the procedure. Because the design has not been completed after the timetable is determined, one may question the correctness of the timetable. Nevertheless, the AASHTO Design and Build Procurement Guide note that a DB has shown less progress development than the DBB. This is most likely because of DB's capability to enables DBT to new during a construction, which can help to ignore delays or change orders.
Federal and state-level DBT procurement regulations enable utilize of the most valuable selection strategies, including price, quality, schedule, and other aspects (if deemed to be in best interest of agency). General DBT procurement is one or two steps. Step by step, interested bidder submits their qualifications as well as past performances and technical advice. In case of a two-step approach, first of all, bidders who interested are required to present a report of past performance, organizational charts, team qualifications, key personnel resumes,...
