Analyzing subsurface geological conditions ghp design and vertical borehole installation

Analyzing Subsurface Geological Conditions: GHP Design and Vertical Borehole Installation


Introduction colorado s unique geological history

Introduction: Colorado’s Unique Geological History


Introduction why is subsurface analysis so important

Introduction: Why is Subsurface Analysis So Important?

  • Design Considerations

  • Liability

  • Cost of Installation

  • Change Orders?

  • Schedule Preparation and Management


Tools that can be used to analyze the subsurface conditions of your project

Tools that can be used to Analyze the Subsurface Conditions of your Project

  • Google Earth

    • Google Earth Geological Layers

    • Aerial View

  • Google Maps

    • Terrain

    • Street View

  • Water Well Permits

    • Aqua Map

    • Well Construction Reports

  • Geotechnical Site Specific Soils Report


Google earth geological map overlay

Google Earth: Geological Map Overlay

  • Geological Map Overlay

    • Used to identify both the overburden and the underlying bedrock formations

    • Shows major geological structures such as fractures, faults, tilted bedrock

    • Can expose bedrock that could contain voids such as caves or fractures

    • Easy to identify glacial and river terrains

Google earth aerial view

Google Earth: Aerial View

  • Google Earth Aerial View

    • Used to identify if bedrock is presence at or near the surface

    • Linear striations can indicate tectonic activity and dipping bedrock

    • Major outcropping visible indicates harder rock such as sandstone or granites

    • Can define glacial and river boundaries

Google Earth: Aerial View


Google maps terrain view

Google Maps: Terrain View

  • Google Maps Terrain View

    • Terrain can be used to identify bedrock, alluvial fans, landslides, river and glacial deposits

    • Steep terrain indicates hard bedrock

    • Terrain inconsistent with surrounding terrain can indicate landslides, alluvial fans, and/or glacial moraines

    • Flat terrain in a valley indicates deeper overburden deposits

    • Flat terrain can also indicate horizontal bedrock such as seen in the western slope as buttes or mesas


Google maps terrain view1

Google Maps: Terrain View


Google maps street view

Google Maps: Street View

  • Google Maps Street View

    • If you can’t personally visit the site, street view can be used to help visibly confirm your analysis

    • Can also be used to identify any site restrictions that may present difficulties for drilling operations


Water well permits aqua map

Water Well Permits: Aqua Map

  • Used to locate onsite and/or nearby water well permits

#4620


Water well permits well permit search

Water Well Permits: Well Permit Search

  • Well Permit Search

    • Look up Permit # in Well Permit Search

    • Click tab Located at Bottom and Open Downloaded Documents


Water well permits construction report

Water Well Permits: Construction Report

  • Water Well Construction Report

    • Review the drillers log and compare to your analysis

      • Does it confirm your analysis?

      • Are there any discrepancies?

      • What is the vicinity of the log to your project location?

    • Depth to Groundwater and Yield (GPM)

      • Establishes if groundwater may be present

      • Yield defines the volume of water in the formation

      • Beware; large volumes of water can come from 1-3’ fractures which will be sealed up with the grout

      • Sandstone tends to hold larger amounts of water that could be exposed to the loop pipe over longer depths


Water well permits construction report1

Water Well Permits: Construction Report

  • Download Construction Report

    • Review Driller’s Log

    • Look at Depth to Groundwater and Yield (GPM)


Geotechnical subsurface soils report

Geotechnical Subsurface Soils Report

  • Soils Report

    • Each new construction project should have this report available at your request

    • Gives an indication of near sub surface conditions (depths 0-45’ in many cases)

    • Indicates overburden thickness and type

    • Can determine bedrock depth and type in many cases

    • Valuable for estimating excavation costs and schedule


Understanding subsurface conditions how it can impact your project

Understanding Subsurface Conditions: How it Can Impact Your Project?

  • Design

    • Reduces liability with the design

    • Could reduce costs by limiting over-design

    • Help determine the most cost effective design for the heat exchanger

  • Costs

    • Complicated geological conditions will increase installation costs

    • Understanding the subsurface can help identify proposals that haven't taken complicated subsurface conditions into consideration

  • Scheduling

    • Complicated subsurface conditions can affect your construction schedule

    • Drilling operations take up space and limit other contractors to execute their work

    • If it is likely potential problems may arise due to the subsurface, you can mitigate the impact to the schedule by scheduling drilling operations early or during a period that will minimize impacts to other construction activities
