40 NCHRP Synthesis 46-04: The Impact of Geotechnical Investigation Scope on Construction Claims, Change Orders, and Overruns Dear: The Transportation Research Board (TRB) is preparing a synthesis on the impact of geotechnical investigation scope on construction claims, change orders, and overruns. This is being done for NCHRP, under the sponsorship of the American Association of State Highway and Transportation Officials, in cooperation with the Federal Highway Administration. Construction claims and change orders due to unanticipated or variable subsurface conditions frequently lead to significant project cost increases and/or schedule delays. The goal of the study is to evaluate and document the magnitude, frequency, and nature of claims, change orders, and overruns resulting from subsurface conditions, and to examine the effect of geotechnical investigation practices on these undesirable outcomes. This survey is the most critical component of the project effort. We are particularly interested in identifying practices that have been successful in reducing such occurrences. The survey is broken into three parts. Part One contains questions related to subsurface investigation practices. Part Two includes general, mostly qualitative questions about claims, change orders, and cost overruns. An optional Part Three requests specific quantitative information regarding claims, change orders, and cost overruns. We anticipate that for some agencies, the information requested in Part Three may not be readily available. If quantitative information requested regarding claims, change orders, and/or cost overruns is not readily available, please skip to the end to submit the partially completed survey rather than abandoning the survey altogether. No responses will be received until you click to submit the survey. Your cooperation in completing the questionnaire will ensure the success of this effort. If you are not the appropriate person at your to complete this questionnaire, please forward it to the correct person. State geotechnical engineers are, in large part, the primary contacts for this survey. It is likely that state construction engineers are better equipped to respond to Parts Two and Three of the survey. To address this, participants are encouraged to share the survey response effort among personnel by following the Instruction 3 below.

41 Please complete and submit the survey by February 11. We estimate that Parts One and Two of the survey will each take approximately 20 minutes to complete. The completion time for optional Part Three may be considerable, but it will vary greatly depending on the availability and accessibility of data. If you have questions, please contact the principal investigator, Andy Boeckmann, at 573-424-0017 or boeckmanna@missouri.edu. Any supporting materials or additional documents that might be useful for this study would be much appreciated and can be sent directly to Andy by email or using the postal address at the end of the survey.

QUESTIONNAIRE DEFINITIONS For the purposes of this survey, the following definitions are used: • Claim: A claim is a legal demand by a contractor for additional compensation or time when the contractor believes he/she is entitled to it under the terms of the contract documents. Potential claim resolutions include denial/rejection, a change order for additional compensation or additional time, or other resolutions involving dispute review boards, mediators, or courts. • Change order: A change order is a formal modification of the scope of work established in contract documents, often including adjustments to compensation and/or schedule. • Cost overrun: A cost overrun refers to instances when the cost of a project or bid item at project completion exceeds its initially contracted cost. • Site characterization: The process of identifying and describing below-ground features via subsurface investigation, including, but not limited to, exploratory borings and laboratory testing. The description of features includes assignment of geotechnical design parameters.

Please use the comment field below to add any explanation, qualification, or clarification to your responses. Optional Part Three, cont’d Page exit logic: Page Logic IF: Question “Does your agency keep data related to or that could otherwise be used to identify claims, change orders, and cost overruns that resulted from subsurface conditions or site characterization practices?” #33 is one of the following answers (“No, and I’m ready to submit my responses from previous pages.”) THEN: Jump to page 11 - Summary of Responses & Submit Button Flag response as complete The remaining questions request the same quantitative information (total number and total costs of claims, change orders, and cost overruns) from the previous page, but the requests are specific to claims, change orders, and cost overruns that have resulted from subsurface conditions or site characterization practices. We recognize such information may not be readily available. If the information is not readily available, you can proceed with estimates, or you can submit your responses from the previous pages and exit the survey by selecting the last response to Question 33 below.

62 33. Does your agency keep data related to or that could otherwise be used to identify claims, change orders, and cost overruns that resulted from subsurface conditions or site characterization practices? Optional Part Three, cont’d Page exit logic: Page Logic IF: Question “If you realize none of the information requested on this page is available, please check the box below and click “Next” at the bottom of this page to skip to the final page of the survey." is one of the following answers (“I don’t have the information requested on this page, and I’m ready to submit all previous responses.”) THEN: Jump to page 11 - Summary of Responses & Submit Button Questions 34 through 42 relate to quantifying the number and costs of claims, change orders and cost overruns experienced by your agency that have resulted from subsurface conditions or site characterization practices since 2009. Responses to these questions should reflect only those claims that can be attributed to subsurface conditions or site characterization practices. We recognize that both records availability and claims filing processes and definitions vary from agency to agency. Please use the comment field at the bottom of this page to add any explanation, qualification, or clarification to your responses. If only some of the data is readily available, please fill in the appropriate fields and leave the others blank. If you realize none of the information requested on this page is available, please check the box below and click “Next” at the bottom of this page to skip to the final page of the survey. Yes, at least some records are available. No, but I can provide reasonable estimates. No, and I’m ready to submit my responses from previous pages. I don’t have the information requested on this page, and I’m ready to submit all previous responses.

What is the cumulative cost of overruns that can be attributed to subsurface conditions or site characterization practices? 42. What is the cumulative total contract cost for projects with cost overruns that can be attributed to subsurface conditions or site characterization practices? Please use the comment field below to add any explanation, qualification, or clarification to your responses. Optional Part Three, cont’d In addition to the cumulative totals of claims, change orders, and cost overruns requested in previous questions, we are also interested in additional information specific to individual claims, change orders, and cost overruns that can be attributed to subsurface conditions or site characterization practices, dating back to 2009. A list of the types of information of interest is included below. Please note we are not requesting the data but inquiring about its availability.

65 43. Is the type of information requested below readily available? Please enter contact information for the agency contact from whom we can request such information. Yes No I don’t know. Hidden unless: Question “Is the type of information requested below readily available?” #43 is one of the following answers (“Yes”,“I don't know.”)

66 Types of information of interest for individual projects with claims related to subsurface conditions or site characterization practices dating back to 2009: Type of project (bridge, roadway, other) Project bid cost Final project cost Project contract arrangement (design-bid-build, design-build, public private partnership, construction manager/general contractor, other) Claim filed by prime or sub? Project dates (start, end, and date of claim, change order, or overrun) Cost of the resolved claim, change order, or overrun Brief description of the nature/cause of the claim, change order, or overrun, including the type of geotechnical element Any additional, non-subsurface conditions claim, change order, or overruns for the project? Cost/magnitude of the subsurface investigation (performed prior to claim, change order, or cost overrun) Any available subsurface investigation data (e.g., a geotechnical report). A point of contact for the project. Thank You! Thank you for taking our survey. Your response is very important to us.
