Preliminary Investigations (PI)

The following are standard Preliminary Investigations Forms, Templates and Files:

  • Bridge Site Data Submittal Form. This is a structural work order form, site data form, and work agreement between the District and Division of Engineering Services (DES), Structures Design or the District and a Consultant Design entity.
  • Bridge Site Data Submittal Form for Non-Standard Sound Walls & Retaining Walls. This is a structural work order form, site data form, and work agreement between the District and Division of Engineering Services (DES), Structures Design or the District and a Consultant Design entity.
  • Bridge Site Data Submittal Form for Sound Walls Carried on a Structure (with no widening or less than 150mm of widening). If a widening is to be done in excess of 150 mm then use the standard BSDS.dot form. This is a structural work order form, site data form, and work agreement between the District and Division of Engineering Services (DES), Structures Design or the District and a Consultant Design entity.
  • This information must be filled out by District Surveys. Prior to a survey crew going out to a site to generate a Digital Terrain Map (DTM), there needs to be an agreement on the Horizontal and Vertical control that will be adhered to all the way through the Construction phase and close out of a Project. Preferably real world coordinates (California), but, they can be what ever the District dictates and will hold constant through out the project.
  • A brief heads up advise on typical mistakes or omissions when producing a Foundation plan.
  • This is a checklist for producing a Foundation Plan.
  • This is an in depth explanation of how to fill out the Bridge Site Submittal Form and some history.
  • Methodology and construction of Foundation Plans.
  • This is a cell library to be added to CAiCE software so that the different data that has been electronically collected is placed on the correct levels when converting over to a MicroStation file(to be done under Tools in CAiCE).
  • This literally is the State border that the DTM/Foundation map should be placed on.
  • Instructions and limits of survey for field crews performing the field surveys.
  • This is a Feature Table that must be attached to the CAiCE Software (Under Tools).
  • Supplemental Vertical Clearance Calculation Sheet. To be used in conjunction with a Bridge Site Data Submittal Form when there are numerous critical clearance points that the Designer needs to be made aware of.
  • This form is used to list and give approximate locations of all utilities at the site.
