BY: _________________________________ BY: ________________________________ NAME: Pitkin County Board of Commissioners NAME: R. Bradley Martin, P.E TITLE: Pitkin County Board of Commissioners TITLE: Senior Vice president ADDRESS: 1670 Broadway Suite 3400 Denver, CO 80202 Attachment A Attachment A March 20, 2026 Subject: Proposed Scope of Professional Services, Geotechnical Data Report, ASE Site Walls, Aspen, Colorado. Proposal Number 2603-0452R Brian Lincoln, P.E. HDR, Inc. 1670 Broadway, Suite 3400 Denver, Colorado 80202 Dear Mr. Lincoln: GROUND Engineering Consultants, Inc. (GROUND) is pleased to submit a proposal to provide a geotechnical data report in support of the proposed site walls planned for construction at the existing Aspen/Pitkin County Airport (ASE) located at 233 Airport Road in Aspen, Colorado. Based on correspondence with the client and provided information, we understand new sound and retaining wall alignments are planned as part of the new terminal project. Based on provided information, our experience with similar projects, and as requested we propose the following: Geotechnical Data Report Components As requested, drill fourteen (14) test holes to evaluate the subsurface and to obtain earth material samples for laboratory testing. The test holes will be drilled at/near the locations requested by the client; however, the locations of the test holes will be determined in the field based on utility locate markings and accessibility. Prior to drilling test holes located within air-side pavements, the pavement will be cored with an approximately 6-inch diameter core bit. The test holes will be drilled to a depth of approximately 40 feet below existing grades (or until practical drill rig refusal, whichever occurs first) using solid-stem augers, hollow-stem augers, and/or ODEX down-the-hole air-percussion drilling equipment. The final depths of the test holes will be determined in the field as exploration progresses and the subsurface profile becomes evident. As requested, sampling will be attempted with a Standard Penetration Test (SPT) sampler every approximate 2½ vertical feet for the first 20 feet of each test hole, followed by sampling on approximate intervals of 5 vertical feet until a depth of approximately 40 feet below existing grades. Laboratory testing will be selected by HDR, based on the conditions encountered during exploration. Based on discussions with HDR, a laboratory testing program consisting of thirty (30) classifications (natural moisture content, Atterberg limits (liquid and plastic limits), gradation and hydrometer tests); ten (10) remolded direct shear tests (3-points Attachment A ASE Site Walls Aspen, Colorado 3/20/2026 Proposal No. 2603-0452R Page 2 of 8 each); ten (10) unconfined compressive strength tests; three (3) 1-dimensional consolidation tests; and three (3) suites of corrosivity tests (pH, water-soluble sulfates, water-soluble chlorides, and resistivity) was assumed. Laboratory tests will be billed per the fee schedule provided herein. Prepare a report summarizing the data obtained. Field and electronic logs of the test holes (PDF and gINT formats, respectively) will be provided, as well as laboratory testing results. An electronic copy (PDF format) of the report will be provided. Hard/paper copies are available upon request. Field work, data analysis and report preparation will be conducted under the supervision of a Colorado-licensed professional engineer. Fees Based on the proposed scope of services outlined above, we estimate a fee of $115,011.5 to provide the geotechnical data report. Our fees will be billed on a not-to-exceed (NTE) cost (external services including drilling and private locating) and time/unit rate basis (internal services including coordination, field logging, laboratory testing, etc.) in accordance with the fee schedule herein. This fee assumes normal work day (Monday to Saturday – 7 am to 6 pm) operations during annual spring ASE closure period between April 23 and May 21, 2026. It also assumes drilling can be completed within approximately two week-long mobilizations. If the scope cannot be completed within the NTE limit above, it will be necessary to either reduce this scope or increase the NTE limit. If additional services are required beyond the scope of services outlined above, we propose that our fees for the additional services be in accordance with the hourly and unit costs presented in the Fee Schedule within this scope of services. As times required for post-report consulting and development of additional parameters are difficult to forecast, we propose to provide these services on an hourly and unit cost basis in accordance with the Fee Schedule. Specifically, a rate of $160 per hour will apply for a project engineer or geologist, $200 per hour for a senior project engineer or geologist, and $235 per hour for a GROUND principal. GROUND will not proceed with additional services; however, without your prior approval and authorization. Considerations/Exclusions GROUND Engineering Consultants, Inc. will provide geotechnical data only, as described herein, and will not be the Geotechnical Engineer of Record (GEOR) for this project. Geotechnical analysis and the development of recommendations will be performed by HDR. We assume that the site will be accessible to a conventional, truck-mounted drilling rig and support truck hauling an air compressor. Our scope does not include snow removal, Attachment A ASE Site Walls Aspen, Colorado 3/20/2026 Proposal No. 2603-0452R Page 3 of 8 construction of access routes or drilling pads, fence removal, or any other measures necessary to obtain physical access to the test hole locations. Client will furnish right-of-entry for GROUND and GROUND’s Subconsultants/Subcontractors to make borings, surveys and/or conduct other surface or subsurface explorations. Furthermore, we understand that this work will be performed during the seasonal maintenance shutdown of ASE; escorts will be provided by HDR, if necessary. GROUND and its Subconsultants/Subcontractors will take reasonable precautions to reduce damage to property. Some damage to landscaping, pavements, etc., is inherent to geotechnical drilling and should be expected by the Client/Owner. GROUND will backfill the test holes with auger returns, patch paved areas with cold patch asphalt or grout and generally leave the site reasonably restored. For the test holes located within air-side pavements, GROUND will reinstate competent pavement cores using Utilibond or similar bonding compound. Additional site repairs including, but not limited to, more extensive site clean-up, restoring ruts/damage in landscaped areas, repairing broken irrigation systems, replacing cracked curbs or flatwork, more elaborate pavement repairs, etc., are outside of our scope of services. GROUND will notify public utilities through the Utility Notification Center of Colorado (UNCC / Colorado 811). GROUND will not be liable for damage to any private utilities as a result of exploration. By entering into an agreement with GROUND, the Client accepts this limitation and will either coordinate this utility identification and/or provide information to GROUND regarding the location(s) of on-site utilities. We have assumed that the Client will notify the property owner(s) within 48 hours of proposal execution. Evaluation/identification of hazardous/contaminated materials that may be present, is not included in GROUND’s scope of services, unless otherwise indicated. The Client/Owner must inform GROUND to the presence of hazardous/contaminated materials, known to them prior to performance of any subsurface exploration. Neither does our scope include fees associated with obtaining permits to complete our field services or to respond to municipal or other agency review of our report. We have assumed that the test hole locations and elevations will be surveyed by others on the project team, if necessary. As part of this proposed scope of services, GROUND intends to utilize the Client-provided site plan indicating existing features, Google Earth/Map imagery, and a hand-held GPS to determine the location of the test holes. Groundwater level observations will be performed during drilling operations; test holes will be backfilled upon drilling completion per Code of Colorado Regulations (2 CCR 402-2). In the event the Client desires additional/repeated groundwater level observations, Attachment A ASE Site Walls Aspen, Colorado 3/20/2026 Proposal No. 2603-0452R Page 4 of 8 GROUND must be notified prior to proposal/agreement execution so that necessary revisions to the scope and fee can be made. A contractor who relies upon GROUND’s reporting for development of their scope of work or cost estimates may find the geotechnical information to be inadequate for their purposes or find the geotechnical conditions described to be at variance with their experience in the greater project area. The contractor is responsible for obtaining the additional geotechnical information that is necessary to develop their work scope and cost estimates with appropriate precision. Schedule We propose to initiate the evaluation (public utility locates, scheduling drilling, etc.) within 3 days of being given notice to proceed (i.e., receipt of a signed copy of this proposal). We anticipate that preliminary subsurface information will be available upon request approximately 2 to 4 weeks after drilling completion, and that the report should be completed approximately 4 to 6 weeks after drilling completion. GROUND will attempt to adhere to this schedule; however, this remains dependent upon favorable weather conditions, subcontractor availability, site access, and buried utility locations, and therefore cannot be guaranteed. In any event, we will notify you of our progress and pertinent information, as it becomes available. Attachment A ASE Site Walls Aspen, Colorado 3/20/2026 Proposal No. 2603-0452R Page 5 of 8 Authorization Please review the General Conditions within this proposal, which contain a limitation of GROUND’s liability. Also note that GROUND reserves the right to alter the scope items if deemed necessary and withhold data and reports until we have received a signed proposal. If you have any questions, concerns, or comments regarding this proposal, please contact this office. If this proposal meets with your approval, please return a signed copy to this office at which time we will sign and return an executed copy to you. This proposal is valid for 30 days. If GROUND is requested to commence work before this proposal is signed, this proposal along with the attached General Conditions will constitute the terms of our contract. We appreciate this opportunity to work with you on this project. Sincerely, GROUND Engineering Consultants, Inc. Brian Knecht, P.G., P.E.

GENERAL CONDITIONS – ENGINEERING INTENT OF SERVICES: The services and any subsequent analysis and reporting performed by GROUND Engineering Consultants, Inc. (hereafter referred to as the Consultant) under this Agreement are intended to assist the Client in planning and/or designing the project. Any exploration, testing, and/or analysis associated with the services will be performed by Consultant solely to fulfill the purpose of this Agreement. Any changes in project plans or schedule, referenced within Consultant’s reporting should be brought to the attention of the Consultant, in order that provided geotechnical information be reevaluated and, as necessary, modified. Any geotechnical conclusions and information in Consultant’s reporting will rely upon subsurface exploration at a limited number of exploration points, as well as the means and methods described. The Client agrees to accept that subsurface conditions are interpolated between and extrapolated beyond these locations and it is not possible to guarantee the subsurface conditions are as indicated. Actual conditions exposed during any subsequent construction may be expected to differ from those encountered during site exploration. Additional exploration and laboratory analysis can always be performed to further evaluate the site’s subsurface conditions, albeit at additional time and cost. The Consultant is available to discuss the benefits of additional exploration and laboratory analysis with the Client. The Scope of Services presented reflects the Client’s preferences, objectives, budget, and schedule as understood by Consultant at the time of proposal preparation. The resultant information provided may not be sufficient for use by other parties or other purposes. In the event the Client or any user of Consultant’s reporting does not fully understand the earth conditions at the project site, the potential risks affiliated with those conditions, and the acceptance of responsibility to manage/mitigate these risks, Consultant encourages that they contact a representative of the Consultant for further assistance. Furthermore, if the information provided in Consultant’s reporting is not fully understood by the Client, our office should be contacted immediately. A contractor who uses Consultant’s reporting for development of his scope of work or cost estimates may find the geotechnical information and conclusions therein to be inadequate or insufficient for his purposes or find the geotechnical conditions described to be at variance with actual conditions or his experience in the greater project area. The contractor is responsible for obtaining the additional geotechnical information that is necessary to develop his work scope and cost estimates with appropriate precision. The Client agrees that it will require any contractor or subcontractor to indemnify Consultant and its officers, agents, and employees for any use of the information generated as a result of the scope of services provided with respect to this Agreement, or, failing to do so, will indemnify Consultant directly for any such use. ALL DEVELOPMENT CONTAINS INHERENT RISKS: It is important that ALL aspects of Consultant’s reporting, as well as the estimated performance (and limitations with any such estimations) of proposed project improvements are understood by the Client and Project Owner (if different). Utilizing reported information/parameters for planning, design, and/or construction constitutes understanding and acceptance of the indemnity provisions governing this Agreement, as well as understanding and acceptance of information/parameters provided, potential risks, potential deviation from actual site conditions, performance estimates, as well as the limitations inherent within such estimations and information provided. STANDARD OF CARE: In providing its services, Consultant shall perform in a manner consistent with that degree of care and skill ordinarily exercised by similar members of Consultant’s profession practicing under the same or similar circumstances with the same or similar scope of services. COMMENCEMENT: If Consultant commences performance of all or any portion of the services under this Agreement upon Client’s verbal or written authorization but without a signed agreement in place, Client shall be deemed to have approved and ratified this entire Agreement and the terms of this Agreement shall be fully enforceable in the same manner as if a signed agreement were in place. INFORMATION PROVIDED BY OTHERS: The Client agrees to assist Consultant by placing at its disposal available information pertinent to Consultant’s services. It is the responsibility of the owner or supplier of such documents, either electronic or non-electronic, to ensure that Consultant’s use does not violate any copyright or confidentiality that may be pertinent to the supplied information. The Client recognizes that it is impossible for Consultant to assure the accuracy, completeness, and sufficiency of such information either because it is impossible to verify, or because of errors or omissions that may have occurred in information provided by others. The Client agrees Consultant cannot and shall not be held accountable for information so provided by others. HAZARDOUS MATERIALS: Unless otherwise indicated in the scope of services for this project, nothing in this Agreement shall be construed as providing any type of service relating to an assessment of the possible presence of oil, hazardous materials, asbestos, radioactive materials or any other environmental contaminants, which may be subject to regulatory control, or for the design of systems to remove, treat, handle, or dispose of contaminated materials. The Client/Owner must inform Consultant to the presence of hazardous/contaminated materials, known to him, prior to performance of any subsurface exploration. RIGHT-OF-ENTRY: Unless otherwise agreed, the Client will furnish right-of-entry for the Consultant and Consultant’s Subconsultants/ Subcontractors to make borings, surveys, and/or conduct other surface or subsurface explorations. The Consultant and its Subconsultants/ Subcontractors will take reasonable precautions to reduce damage to property. However, cost of restoration or damage that may result from field operations is not included in the fee unless otherwise stated.

The time for completion of Consultant’s services shall be extended and compensation equitably adjusted. Client agrees that Consultant shall not be responsible for associated damages.

LIMITATION OF LIABILITY: The geotechnical engineering, engineering geology, and related services performed under this Agreement will be performed with the care and skill ordinarily exercised by similar members of Consultant’s profession practicing under the same or similar circumstances with a similar scope of services. No warranty, expressed or implied, is made or intended by rendition of consulting services or by furnishing oral or written reports of the findings and/or conclusions made. The economic or technical performance of this or any project cannot be guaranteed in any respect. In no event shall the Consultant be liable to the Client for any consequential, incidental, indirect, special, punitive or exemplary damages suffered or incurred in connection with this Agreement.

In addition, to the fullest extent permitted by law, the Client agrees to release, indemnify, and hold the Consultant, its past or present employees, owners, directors, or officers, harmless for any damage, liability, or cost, including reasonable attorneys’ fees, to the extent caused by Client’s negligent acts, errors, or omissions in Client’s performance in the project under this Agreement. CORPORATE PROTECTION: It is agreed to by all parties affiliated with this Agreement that the services provided by the Consultant that are in any way connected to this project shall not subject Consultant’s employees, owners, directors, or officers to any personal exposure for risks associated with any portion of this project. Therefore, and not withstanding anything to the contrary that may be contained herein or in any other document related to this project, the Client, future owners, future users, and/or any other trades or professional, agrees that as the sole and exclusive remedy for any claim, demand, or suit shall be directed and/or asserted against the Consultant, a Colorado Corporation, and not against any individuals, including Consultant’s past or present employees, owners, directors, or officers. DISPUTE RESOLUTION: This Agreement is to be governed by the law of the State of Colorado. In an effort to resolve any conflicts that arise between the parties to this Agreement, the Client and the Consultant agree that any dispute, controversy, or claim arising out of or relating to this Agreement shall be submitted to non-binding mediation before a mutually agreed upon mediator.

Described below are the terms and conditions for providing to you such notices and disclosures electronically when we send you documents for electronic signature. Acknowledging your Access, Intent, and Consent to Receive and Sign Materials Electronically To confirm that you can access this information electronically, which will be similar to other electronic notices and disclosures that we will provide to you, please verify that you were able to read this electronic disclosure and that you also were able to print on paper or electronically save this page for your future reference and access or that you were able to e-mail this disclosure and consent to an address where you will be able to print on paper or save it for your future reference and access. Further, if you consent to receive notices and disclosures exclusively in electronic format on the terms and conditions described above, please let us know by clicking the 'I agree' button below. By checking the 'I Agree' box, I confirm that:  I am establishing my intent to be bound to the transaction, and indicating that I am fully aware of the purpose for which the signature is being provided.  I can access and read this Electronic CONSENT TO ELECTRONIC RECEIPT OF ELECTRONIC RECORD AND SIGNATURE DISCLOSURES document; and  I can print on paper the disclosure or save or send the disclosure to a place where I can print it, for future reference and access; and  Until or unless I notify Pitkin County as described above, I consent to receive from exclusively through electronic means all notices, disclosures, authorizations, acknowledgments, and other documents that are required to be provided or made available to me by Pitkin County during the course of my relationship with you. Signing Documents without a Pitkin County DocuSign Account: Pitkin County may not require all document signers to be authorized users of the Pitkin County DocuSign Account. Please read the information below carefully and thoroughly, and if you can access this information electronically to your satisfaction and agree to these terms and conditions, please confirm your agreement by clicking the 'I agree' button at the bottom of this document. When you don't have a DocuSign account, you will be provided the opportunity to agree to the Legal Disclosure each time you open an "envelope" for signing, at this time, you can download and retain this disclosure. Pitkin County will forward completed documents that you've reviewed, processed or signed via email. Should you require copies of these signed documents (e.g., if they get deleted from your email account) you should request those documents from Pitkin County under the Colorado Open Records Act by contacting the Pitkin County custodian who sent you the document for signature. Signing Documents with a Pitkin County DocuSign Account: Electronic Record and Signature Disclosure created on: 3/20/2020 3:28:13 PM Parties agreed to: Greg Boyd, Brad Martin, Diane Jackson Please read the information below carefully and thoroughly, and if you can access this information electronically to your satisfaction and agree to these terms and conditions, please confirm your agreement by clicking the 'I agree' button at the bottom of this document. Getting paper or electronic copies At any time, you may request from us a paper or electronic copy of any record provided or made available electronically to you by us. For such copies, as long as you are an authorized user of the DocuSign system you will have the ability to download and print any documents we send to you through your DocuSign user account for a limited period of time (usually 30 days) after such documents are first sent to you. After such time, if you wish for us to send you paper or electronic copies of any such documents from our office to you, you may be charged a per-page fee. You may request delivery of such paper or electronic copies from us by following the procedure described below. Withdrawing your consent If you are an authorized DocuSign Account holder, you can decide to receive notices and disclosures from us electronically, you may at any time change your mind and tell us that thereafter you want to receive required notices and disclosures only in paper format. Described below is the process for informing us of your decision to receive future notices and disclosure in paper format and also how to withdraw your consent to receive notices and disclosures electronically. Consequences of changing your mind If you elect to receive required notices and disclosures only in paper format, it will slow the speed at which we can complete certain steps in transactions with you and delivering services to you because we will need first to send the required notices or disclosures to you in paper format, and then wait until we receive back from you your acknowledgment of your receipt of such paper notices or disclosures. To indicate to us that you are changing your mind, you must withdraw your consent using the DocuSign 'Withdraw Consent' form on the signing page of your DocuSign account. This will indicate to us that you have withdrawn your consent to receive required notices and disclosures electronically from us and you will no longer be able to use your DocuSign user account to receive required notices and consents electronically from us or to sign electronically documents from us. All notices and disclosures will be sent to you electronically Unless you tell us otherwise in accordance with the procedures described herein, we will provide electronically to you through your DocuSign user account all required notices, disclosures, authorizations, acknowledgments, and other documents that are required to be provided or made available to you during the course of our relationship with you. To reduce the chance of you inadvertently not receiving any notice or disclosure, we prefer to provide all of the required notices and disclosures to you by the same method and to the same address that you have given us. Thus, you can receive all the disclosures and notices electronically or in paper format through the paper mail delivery system. If you do not agree with this process, please let us know as described below. Please also see the paragraph immediately above that describes the consequences of your electing not to receive delivery of the notices and disclosures electronically from us.
