    • Hydrological data
    • Traffic studies
    • Materials engineering
    • Zoning assembly
    • Land use information like deeds
    • Environmental assessments
    • Impact assessment

4.2.3. FINAL DESIGN PHASE

After approval of preliminary design, basic services for final design are as follows:

  1.  Preparation of final drawing plans 
  2. Preparation of revised estimate of probable total cost of the project
  3. Furnishing the necessary data for the application of regulatory permits.
  4. Preparation of basic construction documents for review and approval of the client.
  5. Furnishing required copies for necessary documents.
  6. Provision of periodic status reports

4.2.4. BIDDING OR NEGOTIATING PHASE


Services under this phase may include:

  3. Assisting in determination of contractors, subcontractors, and materials suppliers.
  4. Advice on acceptability of materials and equipment proposed by contractors and suppliers.

4.2.5. CONSTRUCTION PHASE


Services in this phase include consulting and advising the client during construction.

*Most Civil Engineers are not willing to assume the responsibilities associated with construction phase services without providing resident project representative services at the site.

  1. Review work of constructors through design concepts and shop and erection drawings.
  2. Review test reports on materials and equipment.
  3. Visiting the project site to observe and check progress and quality of work.
  4. Providing services by a full-time resident project representative and by supporting staff.
  5. Issuing instructions from the client to the contractors - interpret and clarify; preparation of change orders, special inspections, testing of work, recommendation to the acceptability of work.
  6. Recommend the client on corrective actions or contractual measures that may be exercised by the client.
  7. Preparing sketches required to resolve problems due to actual field conditions.
  8. Determining progress of work and preparation of payments due.
  9. Observing and assisting performance tests and initial operation of the project.
  10. Preparation of record drawings from information submitted by the contractor.
  11. Conducting final inspection and reporting the completion of the project, recommend final payments to contractors and release retained percentages.

4.2.6. OPERATION PHASE


The civil engineer may assist in the start-up of the project operations.


  • Preparation of a manual for both operation and maintenance requirements
  • Provide assistance in adjusting and balancing equipment
  • Identify deficiencies and assisting in obtaining corrections
  • Perform inspection before the end of the warranty period
  • Assist in operator training
  • Set up job classifications and salaries
