HIGHWAY SURVEYOR

1. Planning & Design

Before construction begins, engineers conduct:

• Feasibility studies
• Traffic surveys
• Soil investigation / geotechnical analysis
• Environmental impact assessment (EIA)
• Alignment and route selection
• Design of pavement, drainage, and structures

Outputs include: drawings, specifications, and cost estimates.

2. Site PreparationActivities

• Clearing and grubbing (removal of vegetation, debris)
• Demolition of existing structures
• Relocation of utilities (water lines, cables, etc.)
• Earthwork planning and site marking by surveyors

3. Earthworks

This is one of the most important stages.

Processes

• Cutting (removing soil/rock from high areas)
• Filling/Embankment (adding soil to low areas)
• Compaction using rollers
• Grading and levelling to achieve design slope and shape

Materials

• Natural soil
• Selected fill material
• Rock
• Stabilized soil (lime/cement treated)

4. Subgrade Preparation

The subgrade is the top of the compacted soil layer.

Tasks

• Achieve required density and CBR (California Bearing Ratio)
• Shape and level the formation
• Fix soft spots with soil stabilization or geotextiles

5. Sub-Base and Base Course Construction

These layers provide structural strength above the subgrade.

Sub-base (optional depending on design)

• Granular Sub-Base (GSB)
• Crusher run material

Base Course

• Water Bound Macadam (WBM)
• Wet Mix Macadam (WMM)
• Cement-treated base (CTB)
• Bitumen-treated base (BTB)

6. Pavement Construction1. Flexible Pavement (Asphalt Roads)

Layers include:

• Prime coat + Tack coat
• Binder course (asphalt)
• Wearing course (asphalt concrete, SMA, or mastic asphalt)

2. Rigid Pavement (Concrete Roads)

Steps include:

• Formwork setting
• Placing reinforcement (if required)
• Pouring and vibrating concrete
• Curing and joint cutting

7. Drainage Construction

Essential to extend pavement life.

Types:

• Side drains
• Culverts
• Cross drainage structures
• Stormwater systems
• Median drains

8. Structures Along the Road

• Bridges and culverts
• Retaining walls
• Box drains
• Underpasses and overpasses
• Guardrails and barriers
• Road signs and markings

9. Finishing Works

• Road shoulders
• Road marking (thermoplastic, paint)
• Traffic signs and signals
• Curbstones
• Landscaping
• Street lighting

10. Quality Control & Testing

Common tests:

• Soil compaction (Proctor, sand cone)
• Material gradation
• Asphalt density and temperature
• Concrete slump and strength tests
• Level checks using survey equipment

11. Safety During Construction

• Traffic management and signage
• PPE for workers
• Hazard identification and control measures
• Safe equipment operation
