Common use of Existing Ground Model Clause in Contracts

Existing Ground Model. 35 Developer shall create an integrated-model of the existing condition to create a digital terrain 36 model (DTM) using Bentley’s InRoads/Site/Survey Select CAD. The Existing Ground 37 Modelexisting ground model must include existing ground surface and subsurface elements 38 (including the best available information for: drainage structures, Utilities, and bridge and wall 39 foundations), features utilizing data from light detection and ranging (LiDAR), subsurface Utility 40 evaluation, field surveys, and existing plans data collection including currently available LiDAR 41 or other existing ground surface data (.dtm or .tin format). Developer shall verify the DTM for 42 accuracy through field procedures of locating well-defined and random check points (not 43 included in the creation of the DTM surface) systematically dispersed throughout the Site and 44 compared to the DTM. Developer shall comply with the requirements in the following manuals 1 available from ADOT at ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇▇/business/engineering-and- 2 construction/EngineeringSurvey in creating DTMs: (1) Manual for Field Surveys, (2) Location 3 Survey P-codes for Bentley InRoads, and (3) General Specifications for Photogrammetric 4 Mapping. Developer shall submitinclude the Existing Ground Modelexisting ground model in 5 both DTM and LandXML format with the 3D Models.

Existing Ground Model. 35 18 Developer shall create an integrated-model of the existing condition to create a digital terrain 36 19 model (DTM) using Bentley’s InRoads/Site/Survey Select CAD. The Existing Ground 37 Modelexisting ground model Model 20 must include existing ground surface and subsurface elements 38 (including the best available 21 information for: drainage structures, Utilities, and bridge and wall 39 foundations), features utilizing 22 data from light detection and ranging (LiDAR), subsurface Utility 40 evaluation, field surveys, and 23 existing plans data collection including currently available LiDAR 41 or other existing ground 24 surface data (.dtm or .tin format). Developer shall verify the DTM for 42 accuracy through field 25 procedures of locating well-defined and random check points (not 43 included in the creation of the 26 DTM surface) systematically dispersed throughout the Site and 44 compared to the DTM. 27 Developer shall comply with the requirements in the following manuals 1 available from ADOT at 28 ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇▇/business/engineering-and- 2 and-construction/EngineeringSurvey in creating 29 DTMs: (1) Manual for Field Surveys, (2) Location 3 Survey P-codes for Bentley InRoads, and (3) 30 General Specifications for Photogrammetric 4 Mapping. Developer shall submitinclude submit the Existing 31 Ground Modelexisting ground model Model in 5 both DTM and LandXML format with format. 32 110.10.2.5.2 InRoads Files (Design Files) 33 Developer shall prepare InRoads Design Files including template library (*.itl), the 3D Modelspreference 34 files (*.xin), alignment files in both *.alg and LandXML formats, and new design surfaces in 35 LandXML format.

Existing Ground Model. 35 18 Developer shall create an integrated-model of the existing condition to create a digital terrain 36 19 model (DTM) using Bentley’s InRoads/Site/Survey Select CAD. The Existing Ground 37 Modelexisting ground model Model 20 must include existing ground surface and subsurface elements 38 (including the best available 21 information for: drainage structures, Utilities, and bridge and wall 39 foundations), features utilizing 22 data from light detection and ranging (LiDAR), subsurface Utility 40 evaluation, field surveys, and 23 existing plans data collection including currently available LiDAR 41 or other existing ground 24 surface data (.dtm or .tin format). Developer shall verify the DTM for 42 accuracy through field 25 procedures of locating well-defined and random check points (not 43 included in the creation of the 26 DTM surface) systematically dispersed throughout the Site and 44 compared to the DTM. 27 Developer shall comply with the requirements in the following manuals 1 available from ADOT at 28 ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇▇/business/engineering-and- 2 and-construction/EngineeringSurvey in creating 29 DTMs: (1) Manual for Field Surveys, (2) Location 3 Survey P-codes for Bentley InRoads, and (3) 30 General Specifications for Photogrammetric 4 Mapping. Developer shall submitinclude submit the Existing 31 Ground Modelexisting ground model Model in 5 both DTM and LandXML format with the 3D Modelsformat.
