I'm doing a senior design project, which is design an academic building for Wentworth Institute of Technology.
Please see attached for project details.
- Recommendations for the type of foundation we must use in 5-6 story academic building.
- Soil parent material
- Depth to groundwater
- Bedrock type
- Bedrock depth
- Boring logs for the site.
Review this geotechnical information and how it relates to your project (i.e., foundation design, road work, grading, etc.). As part of the report, provide a topographical map of the site that includes the following information:
- Site topography
- Significant land features (wetlands, rivers/streams and other water bodies, existing roads,
- Scale and orientation
As you start your senior design project, you will immediately see that you need information on thesoils and bedrock that exist at your site.
You will have to request the information you need from your "Geotechnical Consultant". But to start the process, you first have to do your own library research tofind whatever information there is for your site. At a minimum, your design team must find the sitetopography and the general description of the soils that are on the site. Now, having this initial information, you will position the structures and facilities that your group is planning. Based on thetopography and the neighboring streets and roads, and the wetlands or rock outcrops, where do youwant to locate your building(s), and parking lots and detention basins (if needed) also, where are the major utilities, particularly those affected by gravity.
To start this process, your group should go the WIT library and search out the U.S. Geological Survey topographic plans (also called Quad or Quadrangle Sheets) for your site. Then, for sites in Massachusetts, look up the appropriate Soil Survey for the county you are in. Most counties are available in hardcopy, but a few are on-line now.
Now go through the following steps:
• Look for the air-photo map with your site and determine the soil units and boundaries for the land parcel you are going to develop.
• Determine what the symbols refer to - the particular soil formation name. What type of soilisexpected? Getacopyofthedescriptionsforeachunitonyoursite.
• What is the geological origin for each soil unit? You will need to know the geological originfor the soils. The variation of soils on the site may affect where you locate buildings and other facilities.
• Determine the general engineering properties for the soils on your site by digging through thevarious tables. At a minimum you need to determine the gradation of soils and plasticity. How much passes the No. 200 sieve? What is the D10 and the Cu? What are the Atterberg Limits? What is the expected permeability of the soils? Are cobbles and boulders expected?
• What other information is available on the site soils? Shear strength? Compressibility?
