Transcript of "site investigation"

  1. 1. SITE INVESTIGATION PREPARED BY SARINA
  2. 2. <ul><li>Site Investigation (SI) is the exploration or discovery of the ground conditions to enable engineers to make informed design decisions. </li></ul><ul><li>  </li></ul>
  3. 3. OBJECTIVE OF SI <ul><li>The British Standard Code of Practice BS 5930:1991 gives a list of the objects of site investigation as follows: </li></ul><ul><li>  </li></ul><ul><li>To assess the general suitability of the site and environs for the proposed works </li></ul><ul><li>2. To enable an adequate and economic design to be </li></ul><ul><li>prepared, including the design of temporary works </li></ul>The British Standard Code of Practice BS 5930:1991 gives a list of the objects of site investigation as follows:
  4. 4. <ul><li>3 . To plan the best method of construction </li></ul><ul><li>4. To determine the changes that may arise in the ground and environmental conditions , either naturally or as a result of the works, and the effect of such changes on the works, and the environment in general </li></ul>
  5. 5. STAGE OF SI <ul><li>DESK STUDY </li></ul><ul><li>2. SITE RECONNAISSANCE </li></ul><ul><ul><li>3. DETAILED SITE EXPLORATION AND SAMPLING </li></ul></ul><ul><ul><li>4. FIELD TEST / IN-SITU TESTING </li></ul></ul><ul><ul><li>5. LABORATORY TESTING </li></ul></ul><ul><li>6. REPORT </li></ul>
  6. 6. <ul><li>This is essentially the collection of a wide variety of information relating to the site. </li></ul><ul><li>e.g. maps, drawings; details of existing or historic development, local authority information; geological maps, memoirs, records; details of utilities, services, restrictions, right-of way, ownership of adjacent property; aerial photograph. </li></ul>
  7. 7. <ul><li>An early examination of the site by appropriate </li></ul><ul><li>experts is most desirable. </li></ul><ul><li>eg. Geologist, land surveyor, soils engineer, hydrologist etc. </li></ul><ul><li>Information should be collected on the overall </li></ul><ul><li>site layout, topography, basic geology; details </li></ul><ul><li>of access, entry and height restrictions </li></ul>
  8. 8. <ul><li>HOW MANY BH OR OTHER SI METHOD </li></ul><ul><li>CRITERIA OF TERMINATING BH </li></ul><ul><li>FIELD TEST;CRITERIA & FREQUENCY </li></ul><ul><li>SAMPLING TYPE; CRITERIA & FREQUENCY </li></ul><ul><li>REFERENCE NOTE;FOR BUILDING & ROADS PROJECT </li></ul><ul><li>DOCUMENTATION; DRAWINGS </li></ul>
  9. 9. Projek Jarak 9m) Kedalaman Bangunan satu tingkat 10 - 30 6 -9 m dari dasar asas Bangunan ‘Multi Storey’ 15- 30 2 kali lebar struktur Lebuh raya 250 - 500 Minimum 1- 1.5m di bawah subdred Empangan tanah 40 -80 Minimum 12- 15 m atau 3 m dalam batuan keras PROJECT DISTANCE (m) DEPTH Sigle storey 10 - 30 6 -9 m from foundation base ‘ Multi Storey’ 15- 30 2 X Structure width Highway 250 - 500 Minimum 1- 1.5m below subgred Soil dam 40 -80 Minimum 12- 15 m atau 3 m in hard rock
  10. 10. <ul><li>Investigation of detailed geology and sub-surface soil conditions using surface surveys, trial pits, headings, boreholes, sounding, geophysical methods, as appropriate; survey of groundwater conditions over a signification period of time </li></ul>
  11. 11. <ul><ul><ul><li>MACINTOSH PROBE </li></ul></ul></ul><ul><ul><ul><li>CONE PENETRATION TEST, CPT </li></ul></ul></ul>
  12. 12. <ul><li>SHALLOW EXPLORATION </li></ul><ul><ul><li>TRIAL PITS </li></ul></ul><ul><ul><li>TRENCH </li></ul></ul><ul><ul><li>HAND AUGER </li></ul></ul>
