Requesting Project Mapping and Surveys Overarching Objective • Ensure all projects have the needed mapping and survey products in a timely manner • Develop and maintain a programmatic approach to correctly identify and request aerial photography, mapping, and surveying with established priorities that… – Meet all Division, Business Unit, and Consultant needs – Reduce changes and rework – Remove Photogrammetry, Location & Surveys, and consultants we utilize from the critical path for project delivery – Ideally, have mapping and surveys underway or completed “before the 12, 24, & 36 month clock starts” for project development 3

Requesting Mapping and Surveys Background & Continuing Issues • Project mapping and surveys require programmed funding, correct limits, and sufficient lead time to meet delivery schedules • Seek to take advantage of leaf-off flight season – (mid-December to mid-April) – Ideal aerial photography period is February & March • Insufficient coordination, incorrect project limits, and inadequate lead time resulting in late mapping and survey delivery • Limited number of qualified PEFs with capacity to perform aerial photography, mapping, and surveys work 4

Requesting Mapping and Surveys Ongoing Solution • Workgroup established late summer 2017 to address situation • Continue to develop a holistic, programmatic approach to scoping and scheduling mapping and surveys • Provided training for NCDOT Project Managers fall 2017 • Implemented process in fall 2017 with improved results • Still opportunities for improvement • Working on increased outreach and education as we get closer to starting this year’s Requesting Mapping & Surveys cycle 5

Requesting Mapping and Surveys Opportunities for Improvement • Start earlier in year and conduct pre-cycle training • Emphasize looking further out in STIP • Request the proper mapping/survey product for the corresponding stage of project development • Encourage greater utilization of existing statewide orthophotos and LiDAR elevation data • Repeat training webinars and encourage Consultant attendance • Working with Feasibility Studies Unit to generate initial mapping/surveys limits at completion of Express Design • Provide guidelines for mapping and survey limits based on project type 6

Roles / Responsibilities 7

Requesting Project Mapping and Surveys Photogrammetry • Perform flight and photo control planning for mapping and surveys that support NCDOT projects • Acquire controlled aerial photography for majority of projects • Use Limited Services Agreements with multiple firms to generate mapping products • Review and deliver mapping products 8

Requesting Project Mapping and Surveys Location and Surveys • Limited in-house resources to generate survey products • Utilize in-house staff to establish project control since this is the basis for all subsequent mapping and surveys • Use Limited Services Agreements with multiple firms to generate a variety of surveys used for transportation projects • Assist Division Project Development Engineers by serving as the primary contact in requesting, coordinating, and scheduling the appropriate Surveys and Mapping Products with Photogrammetry 9

Requesting Project Mapping and Surveys Division and Central Project Managers • Acquire PE funding • Establish project delivery schedule • Identify needed mapping and surveys products • Create and provide mapping and surveys limits – Submit mapping and surveys limits as a closed polygon in MicroStation dgn format 10
