47 STAs said that they maintain the in-house capability to perform surveying and mapping services, with 34 STAs maintaining photogrammetric capabilities.

38 STAs indicated that they were moving toward a greater use of private sector forces for mapping and photogrammetric services. 10 STAs plan to maintain their current mix of in-house and private sector sources.

30 STAs indicated that their State has a standard operating procedure that establishes surveying standards and specifications on when is it considered practicable to contract surveying and mapping work to private sector sources. Additionally, the survey indicated that STAs consider aerial mapping and LiDAR to be the most practicable service to be accomplished by the private sector.

The table below identifies mapping and photogrammetric services and the number of STAs that maintain in-house capabilities for each service based on results of the survey.

Full results from the survey can be found on the Office of Program Administration’s Consultant Services website at: http://www.fhwa.dot.gov/programadmin/consultant.cfm

In summary, the performance of surveying and mapping activities are commercial activities similar to engineering and architectural consultant services. The benefits of private sector services in the engineering and design areas are widely recognized as providing value to the STAs by providing technical expertise and resources, which may be difficult or expensive for the STAs to maintain in-house. The technology in the field of photogrammetry and mapping is very sophisticated and potentially expensive to maintain a high level of expertise in-house. A qualified and capable private sector exists that can provide STAs with these services.

We ask that Divisions monitor the States use of private sector sources for mapping and surveying as part of the annual stewardship and oversight activities. STAs should be encouraged to periodically evaluate the potential for engaging private sector sources for surveying and mapping services and to report significant changes in their practices to FHWA.

Please contact John McAvoy, Acting Consultant Services Program Manager, 360-619-7591, [email protected] with any questions regarding this survey.

Alabama Alabama Replied: "ALDOT did not include any information for question 1. It would take substantially longer than 24 hours (several weeks but most likely several months) to provide the specified information. ALDOT uses the private sector to provide aerial photography and mapping and has no desire to perform such services in‐house. ALDOT, as well as cities and counties, uses consultants as needed for conventional surveying."

New Hampshire NHDOT has not used photogrammetric mapping for federally funded projects. The scale of projects in the State’s ten year transportation plan does not justify the cost of photogrammetric mapping. The Department has piloted the use of photogrammetric mapping for a state‐aid highway project in 2011, using the 2010 statewide orthoimagery. The use of the photogrammetric mapping for this project was limited based on the resolution of the available orthoimagery.

IA

Yes. Iowa DOT staff collects engineering/topographicsurveydataand photogrammetric mapping to support the planning anddesign of proposedtransportation i mprovement projects. In addition toin‐housesurvey capabilities, the Iowa DOT contracts asignificantamount ofsurveywork,aerialimageryacquisition, airborne LiDAR andmobilemapping toprivate consultants.

TheIowaDOTcentralofficecurrentlyhas astaff of 19individuals devotedtosurveyandphotogrammetric services. Eachof theIowaDOT’s 6districtofficeshaveapproximately3to4 individuals devotedtoboundary/right‐of‐waysurveying.

Thetrendhas been towardagradualincrease in theuseoftheprivatesectorforthecollection ofengineering/topographicsurvey.Thetrendhas beengradualin large partbecause although theIowaDOThasexperiencedsurveystaffingreductions, theproductivelyoftheremaining staff has been significantly increased due to technological advances in boththecollection equipmentandtheprocessing software.Overthepast10years therehasbeen littleornochange in the percentage of work contractedtotheprivatesectorin theareaof photogrammetric services. IowaDOTrelies on theexpertise offeredby privateconsultants tobroaden capabilities to includethe acquisition and processingof airborneLIDARandimplementing advancements inaerialimagerytechnology.

TheIowaDOThas surveystandards andspecifications whichcan be foundin Chapter40, Design SurveySpecifications, of theIowa DOT Design Manual.Thefollowing i s alink tothatdocument: (http://www.iowadot.gov/design/dmanual/manual.html?reload). However, this document does not address the decision process to beused todetermine when asurveyprojectwillbe completedbyIowaDOT staff oraconsultant.Theprimaryfactorin determining survey/photogrammetrywork assignments is the project delivery schedule that is establishedforall projects in theIowaDOT’s development pro gram.Everyeffortis madeto maximizethenumberof survey/photogrammetryprojects thatareaccomplishedbyIowaDOTstaff, butwhen theworkloadexceeds internalresources or the workforce is not sufficient to meet completion dates, then consultants arecontractedforthework. Tofacilitatethis process, theIowaDOTmaintains anumberof ‘on‐call’surveyconsultants and one aerialservices/photogrammetryconsultant that can be called upon to accomplish multiple assignments. Theuseof theprivatesectorhas been significant in being abletodelivertheIowaDOT’s transportation program sincethattime. Numerous privatesectorfirms havebeen i nvolvedon aproject‐by‐project basis aswellas alargenumberof projects completedthrough the‘on call’ consultant contracts. In addition toassisting in thedevelopment ofstandard projects, and providing expertise in implementing new technologies,theIowaDOThas encouragedtheuseof consultants to pursueuniqueservices suchas SUE (SubsurfaceUtilityEngineering), railroaddatacollection andperforming aeronauticalsurveys.
