Geographic Extent The project area is comprised of five parts, as generally shown in Appendix A, Map of Project Areas. The Project Areas are: Project Area 1 Denver Region and Urbanized Area (Approx. 2,655 square miles) Project Area 1a - Urbanized Area Subset (Approx. 700 square miles) Project Area 2 Eastern Plains Project Area (Approx. 1,300 square miles) Project Area 3 Mountainous Project Area (Approx. 1,870 square miles) Project Area 4 - Weld County Project Area (Approx. 1,100 square miles) - Optionally acquired 3

4 These areas combined cover approximately 7,000 square miles of the greater Denver metropolitan region. This potentially includes all of the following counties: Adams, Arapahoe, Boulder, Broomfield, Clear Creek, Denver, Douglas, Gilpin and Jefferson and portions of Weld and Grand. Exact product boundaries shall be defined by a shapefile provided by DRCOG plus a buffer equivalent to the width of a city block, or approximately 300 feet wide. Respondents should understand that the need for DAT in the project areas listed above is contingent on member participation and funding. Depending on the cost breakdown by project area, not all project areas may be chosen for the final scope of work. Tasks and Deliverables The Contractor, contingent upon execution of a subsequent contract, shall furnish all materials, supervision, labor, equipment, and transportation, unless otherwise specified in this RFP to complete the following tasks and deliver the listed products. Task 1 Establish a region-wide network of Ground Control Points (GCPs). The Contractor will establish a region-wide network of GCPs across the DRAPP 2014 project area. This network of GCPs will consist of both hard panels and photo-identifiable points ("well-defined points"). All points will be established using the criteria and a methodology developed with and approved by DRCOG. Requirements of the Contractor include: 1. Submit a GCP plan for establishing sufficient ground control, and of the necessary accuracy, to perform the Data Acceptance Testing of the digital orthophoto processing. 2. Paneling, surveying, and recording of hard control points. All points will be surveyed to an agreed level of accuracy, by a Colorado licensed professional surveyor, following industry standards. Panel point locations will be described and sketched on GPS Log Sheets kept during GPS field observations. Hard control point (panel points) locations will be determined by extending GPS baselines from NGS first order or better control stations utilizing Survey Grade GPS receivers. 3. The identification, surveying, and recording of photo-identifiable points. All points will be surveyed to an agreed level of accuracy, by a Colorado licensed professional surveyor, following industry standards. 4. The combined hard and photo GCPs should be distributed throughout the project area. Deliverables: 1. Within 15 days of contract execution, a preliminary document (GCP Plan) outlining the Contractor s proposed approach for establishing a network of ground control points across the project area is due to DRCOG. This document should, at a minimum, address the following topics: a. Proposed approach for the selection and placement of hard panels. b. A similar statement on the approach for photo-identifiable GCPs. c. An overview of the surveying approach to measure the location of each point. 4

5 d. A summary of the proposed accuracy specifications to be followed in capturing all the points. 2. Within 60 days of contract execution, but before the commencement of imagery acquisition by the digital orthoimagery vendor, the identification, placement, surveying and recording of a network "hard" GCPs across the project area. 3. Within 60 days of contract execution, the identification, surveying, and recording of a network of photo-identifiable GCPs from across the project area. 4. A summary of all hard and photo-identifiable GCPS, delivered as an ESRI shapefile(s) or ArcGIS file geodatabase and in a datasheet (PDF), with geodetic data as attributes. Attribution should include: a. A unique reference ID b. Actual coordinates (in Lat/Long, UTM, and Colorado State Plane) c. Ellipsoid height d. Orthometric height e. Geoid model f. Brief text description of the physical location of the monument. g. Statement of GPS level of accuracy (especially for photo-identifiable points) h. Statement on what datums and adjustments were used to establish the coordinates i. Photos of the point (in the datasheet only) Task 2 Data acceptance testing review of 2014 Digital orthoimagery The Contractor will perform a comprehensive review of every tile of the 2014 DRAPP imagery, in accordance with the Data Acceptance Testing methodology outlined in their response to DRCOG s Request for Proposals. The DAT process will include at least all of the checks outlined in the attached appendix (Appendix C - Data Acceptance Testing Criteria). The DAT Contractor will also perform subsequent review on all imagery that is rejected through the first DAT review. The DAT process will verify the positional accuracy of the imagery and ensure its aesthetic and functional quality. In general terms, the DAT review will examine all the imagery for the following types of errors: 1. Images that do not meet the project s accuracy specifications: Horizontal accuracy of well-defined ground features depicted on delivered ortho images and mosaics shall be as follows, all expressed as 90% confidence interval values: o o o 1-foot ground sample distance (GSD) pixel size products: ±4 feet 6-inch GSD products: ±2 feet 3-inch GSD products: ±1 foot 2. Misalignments in linear features (roads, curbs, building edges, etc.) resulting from poorly aligned mosaics or other imagery processing errors. 3. Warped or wavy bridges/overpasses/viaducts/railroad lines/warehouses/other large linear physical features. 5

6 4. Obvious seams between images. 5. Blurred or out-of-focus imagery, blemishes, noise, smears, or other artifacts introduced in the acquisition or processing of the imagery. 6. Pronounced changes in color balance and contrast. 7. Dark shadows or bright/washed-out spots in the imagery. 8. Buildings that obscure more than 20 percent of adjacent roadways and other transportation features. 9. Obscured valley bottoms in the mountain areas. Criteria Scoring: The Contractor shall evaluate each of the parameters outlined in the criteria (Appendix C - Data Acceptance Testing Criteria). Each parameter shall be scored on a Pass/Fail basis, governed by the rejection condition set out in the Performance Controls section. Overall rejection of any tile may be based on any of the four categorical requirements Positional Accuracy, Aesthetics, Metadata, or File Format. At a minimum, tiles shall be scored as a fail under any of the following conditions: A fail on any parameters weighted 3 or higher. A fail on any parameter in more than one of the categorical requirements. More than two fails on any of the aesthetic parameters. Other failures will be evaluated on a case-by-case basis. The Contractor may also assign any tile a provisional pass if they deem the error minor enough to simply alert the orthoimagery vendor to the problem and have them fix it without further review. The Contractor shall report the results of this testing to the Project Manager who will in turn relay the results to the imagery contractor for remediation. Deliverables: 1. A DAT plan providing a detailed account of the DAT methodology. 2. DAT testing reports documenting review process and outcomes for each dataset reviewed. Reports should be submitted documenting review of pilot, interim and final imagery. Task 3 DAT Review of Associated Data Products. The Contractor will examine all other data produced as part of the imagery production process. This will include the following: 1. Flightlines and overlap documentation; 2. Ground control and AT data/reports; 3. Metadata; 4. DEM used for orthorectification, with metadata; 5. All calibration and analytical reports produced by the Orthoimagery Vendor. 6

7 Deliverables: 1. Reports reviewing the materials listed above, with statements about acceptance or failure. Task 4 Project Management, Reporting & Customer Service The Contractor is expected to communicate frequently with the DRCOG Project Manager to ensure that the project stays on schedule and that product quality meets specifications. This includes: Status reports to DRCOG s Project Manager (via phone or ), as requested; Attendance at DRAPP partner meetings, as requested; Attendance at project meetings with all DRAPP vendors, as requested; Invoices, submitted within 60 days of the completion of each task; The Contractor may be called on at various times throughout the term of the contract to provide expert advice on matters relating to the quality of the digital orthoimagery. Task 5 OPTIONAL: Provide QAQC of LIDAR and Derivatives, if acquired. Contingent on funding, DRCOG may pursue a LIDAR acquisition in portions of project areas 1, 2, and 3. DRCOG may require an independent vendor to review deliverables, which will include the following: Raw Point Cloud; Classified Point Cloud; TIN; DEM; 1 ft (Area 1a only) and 2ft Contours (Area 1 only); System Calibration, Collection, Processing, and QAQC Reports. If the respondent has experience with evaluation of this type of information, the RFP response should include a summary of their expertise, proposed methodology for performing DAT and a description of how results would be reported to DRCOG. The optional pricing form (Appendix D - Pricing Form) shall also be submitted. Please note that this task is optional and does not have to be addressed in the RFP response. Term The awarded contract will begin on the date it is executed by DRCOG and ends, unless sooner terminated under the Terms and Conditions of the Contract or extended by a contract amendment, on May 31, Subject to the availability of funding and Contractor performance, the awarded contract may be extended for another consecutive term, scheduled approximately for the time period between January 2016 and May of

Deliveries to Participants by the Imagery Acquisition Vendor Customer Service Period ends for DRAPP vendors Notification of Additional Work The Contractor agrees to notify DRCOG in writing within 30 days of all new contracts entered into by the Contractor throughout the duration of the DRAPP contact. The DRAPP participants will review this information in light of its potential impact on the ability of the Contractor to continue to successfully serve the DRAPP project. DRCOG may seek written assurance from the Contractor that they have the resources and capacity to take on additional work without any impact on the DRAPP project. Notification of Changes in Project Personnel The Contractor agrees to notify DRCOG in writing within 30 days of any change in personnel assigned to this task. The DRAPP participants will review this information in light of its potential impact on the ability of the Contractor to continue to successfully serve the DRAPP project. DRCOG may seek written assurance from the Contractor that they have the resources and capacity to continue the project without any impact on the DRAPP project. Liquidated Damages Contractor acknowledges that timely, accurate, and complete delivery of imagery and related digital products is crucial to the success of this project and that DRCOG will suffer financial loss if the work is not completed within the milestone and delivery dates specified in the contract. The parties also recognize the delays, expense, and difficulties in proving in a legal proceeding the actual loss suffered by DRCOG. Accordingly, instead of requiring any such proof, Contractor and DRCOG agree that as liquidated damages for delay, Contractor shall pay DRCOG as follows: Liquidated damages shall be assessed against the Contractor for every calendar day a documented and mutually agreed-upon milestone or delivery date set forth in the contract is not met. If the milestone falls on a Saturday, Sunday, or a holiday, the deadline for performing the obligation falls to the next working day. The amount of liquidated damages is as follows: 8

9 Days one (1) through fifteen (15): 0.05 percent of the total contract price Days sixteen (16) through thirty (30): 0.10 percent of the total contract price Day thirty-one (31) and each day thereafter: 0.15 percent of the total contract price After sixty days, the Contractor shall be in default, at which time DRCOG may, at its option, terminate the contract, recover liquidated damages through the date of termination, and additionally, seek damages for breach. DRCOG at its sole option may also choose to waive all or any portion of liquidated damages due. Such a waiver must be in writing signed by the DRCOG Executive Director, and a waiver by DRCOG with respect to a failure to meet any one or more milestone or delivery dates shall not be deemed as, nor construed to require, a waiver with respect to failure to meet any other milestone or delivery dates. Liquidated Damages applied to the Orthoimagery Vendor For the information of the DAT Contractor, DRCOG may seek liquidated damages from its Orthoimagery Vendor for imagery that fails the DAT review a fourth time and/or misses a deadline. The text from their contract is outlined below: "In the event that a scheduled delivery fails DAT review more than four times, DRCOG may, at its option, (i) require delivery of those tiles that have failed DAT review but in such case the price paid for such delivery shall be reduced by a mutually agreed amount or, in the absence of mutual agreement, a prorata amount determined with reference to the number of failed tiles as compared to the total number of tiles within the delivery, or (ii) DRCOG may declare Contractor in breach and seek damages and any other remedies available to DRCOG for such breach." 9
