PLANNING SURVEYS

• PLANNING SURVEYS

  FACT FINDING SURVEYS: Economic Studies - Involves gathering details on the current infrastructure, its usage, population distribution in the area, population growth trends, existing products in the agricultural and industrial sector, and projections for future development in this sector.
• PLANNING SURVEYS

  FACT FINDING SURVEYS: Financial Studies - Focuses on identifying sources of income and analyzing various financial factors. These include funding sources, estimated revenue from vehicle taxes, and toll tax.
• PLANNING SURVEYS

  FACT FINDING SURVEYS: Traffic/Road Use Studies - Gathering information on current road infrastructure, daily traffic volume, traffic flow patterns, and the types of vehicles such as passenger cars, buses, and trucks. It also covers load capacities, average speeds, and future traffic growth trends.
• PLANNING SURVEYS

  FACT FINDING SURVEYS: Engineering Studies - Assess topographical conditions, soil characteristics, and any specific challenges related to construction, drainage, and maintenance.
• These are the three (3) Highway planning:

  • Planning and Assessment
  • Design and Preparation
  • Construction and Maintenance
• These are the three (3) Railway planning:

  • Planning and Feasibility
  • Design and Construction
  • Operation and Improvement
• ENGINEERING SURVEY STAGES (TYPE): MAP SURVEY -

  • Alignment avoiding valleys, ponds, and lakes.
  • Approximate location of the site
  • Finding suitable alternative routes. Approximate location of the site
• ENGINEERING SURVEY STAGES (TYPE): Reconnaissance Survey -

  • To locate variables such as lakes and drainage structures that are not present in the map.
  • To determine the soil type along the routes of all feasible routes
• ENGINEERING SURVEY STAGES (TYPE): Preliminary Survey -

  • To collect detailed and necessary physical information on topography
  • To compare proposals given good alignment
  • To finalize the best alignment
• ENGINEERING SURVEYS STAGES (TYPE) : FINAL LOCATION SURVEY -

  • A detailed layout of the selected route where the center line will then be established.
  • Staking the right of way and the highway and structures for construction.
  • Putting Temporary Bench Marks (TBM) under structures and drainage.
