Existing Ground Model Clause Samples
The Existing Ground Model clause defines the baseline understanding of the physical and geological conditions at a construction site as known before work begins. It typically outlines the data, surveys, or reports that constitute the agreed-upon ground conditions, and may specify how discrepancies between the model and actual site conditions are to be handled. This clause is essential for allocating risk between parties by clarifying who is responsible if unforeseen ground conditions are encountered during the project.

Existing Ground Model. 25 Developer shall create an integrated-model of the existing condition to create a digital terrain 26 model (DTM) using Bentley’s InRoads/Site/Survey Select CAD. The existing ground model must 27 include existing ground surface and subsurface elements (including the best available 28 information for: drainage structures, Utilities, and bridge and wall foundations), features utilizing 29 data from light detection and ranging (LiDAR), subsurface Utility evaluation, field surveys, and 30 existing plans data collection including currently available LiDAR or other existing ground 31 surface data (.dtm or .tin format). Developer shall verify the DTM for accuracy through field 32 procedures of locating well-defined and random check points (not included in the creation of the 33 DTM surface) systematically dispersed throughout the Site and compared to the DTM. 34 Developer shall comply with the requirements in the following manuals available from ADOT at 35 ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇▇/business/engineering-and-construction/EngineeringSurvey in creating 36 DTMs: (1) Manual for Field Surveys, (2) Location Survey P-codes for Bentley InRoads, and (3) 37 General Specifications for Photogrammetric Mapping. Developer shall include the existing 38 ground model in both DTM and LandXML format with the 3D Models.
