📐Bench Mark (BM) Shifting – Surveying Details

Bench Mark (BM) shifting is the process of transferring a known Reduced Level (RL) from an existing/old Bench Mark to a new location where a permanent reference point is required.

1. Basic Concept

BM (Bench Mark): A fixed point having a known RL/elevation.

BS (Back Sight): First staff reading taken on a known point after setting up the level.

FS (Fore Sight): Staff reading taken on the point whose RL is to be determined.

HI (Height of Instrument): Elevation of the line of collimation.

RL (Reduced Level): Elevation of a point with respect to the adopted datum.

2. Main Formula

HI = RL of Known BM + BS

Then:

RL of New BM = HI − FS

For example, if the old BM has RL = 100.000 m, BS = 1.250 m and FS = 0.850 m:

HI = 100.000 + 1.250 = 101.250 m

RL of New BM = 101.250 − 0.850 = 100.400 m

3. Differential Levelling

When the new BM is far away, several instrument setups and Change Points (CPs) are used. The FS on one setup and BS on the next setup are taken on the same stable change point.

A useful check is:

ΣBS − ΣFS = Last RL − First RL

4. Important Field Practices

✅ Keep the BM and change points stable and undisturbed.
✅ Keep BS and FS distances reasonably balanced to reduce errors.
✅ Check the level bubble before observations.
✅ Focus the eyepiece and objective properly to minimize parallax.
✅ Record readings immediately and verify calculations.
✅ Use a suitable datum and maintain consistent RL references.

Note: A BM should be established on a permanent, stable structure or approved survey monument—not on loose or temporary ground.

👉Types of Foundations Used in Buildings

💫Foundations are the structural elements that transfer building loads safely to the supporting soil.

🌟The selection of foundation depends mainly on soil bearing capacity, structural loads, groundwater conditions, column spacing, settlement requirements, and site constraints.

☄A. Shallow Foundations

Generally used when suitable bearing soil is available at a relatively shallow depth.

1. Isolated (Pad) Footing

Supports a single column.

Suitable where soil has adequate bearing capacity.

Common for individual RCC columns.

☄2. Strip (Wall) Footing

A continuous footing provided below a load-bearing wall.

Suitable for uniform soil and moderate wall loads.

Distributes the wall load over a wider soil area.

☄3. Combined Footing

Supports two or more columns on one footing.

Useful when columns are close together or a column is near a property boundary.

Can help reduce eccentric loading.

☄4. Raft (Mat) Foundation

A large reinforced-concrete slab supporting several or all columns/walls.

Useful where soil has low bearing capacity or columns are closely spaced.

Can reduce differential settlement when properly designed.

B. Deep Foundations

Used when adequate bearing strata are not available near the ground surface or when loads/ground conditions require deeper support.

🚧1. Pile Foundation

Consists of piles extending into deeper soil or rock.

Transfers structural loads through end bearing, skin friction, or both.

Suitable for weak surface soils and heavy loads.

🚧2. Well/Caisson Foundation

A large hollow foundation sunk into the ground.

Commonly used for heavy structures and foundations subjected to scour or water-related conditions, particularly bridge works.

🚥Important Note

The foundation type should not be selected from soil type alone.

A geotechnical investigation and structural design are normally required to determine the appropriate foundation size, depth, reinforcement, allowable bearing pressure, and settlement criteria.

Local building codes and site conditions must also be considered.

📐How to Mark an Offset Using a Total Station

🌟Angle & Distance Method

Offset marking with a Total Station is a precise surveying technique used to locate points away from a known reference or control line. It is based on simple right-angle triangle geometry and allows surveyors to accurately transfer design coordinates to the ground.

🔹 Key Components

Base distance (a): Distance measured along the reference line.

Offset distance (b): Perpendicular distance from the reference line to the required point.

Slope distance (c): Distance measured from the Total Station to the offset point.

Horizontal angle (θ): Angle turned from the established reference direction.

🔹 Required Data

✅ Known control/reference point or line
✅ Total Station properly set, centered and levelled
✅ Reference direction/back sight
✅ Required horizontal angle
✅ Required offset or measured distance

🔹 Basic Procedure

1. Set up the Total Station over a known control point and carefully center and level it.

2. Backsight a reference point and establish the correct orientation.

3. Turn the required horizontal angle from the reference line.

4. Enter or measure the required distance using EDM or stake-out mode.

5. Mark the calculated point accurately on the ground.

6. Recheck the angle and distance before fixing the final survey point.

🔹 Right-Angle Offset

For a perpendicular offset, the offset direction is set at 90° to the reference line. This method is commonly used for establishing building corners, road offsets and setting-out points.

🔹 Common Applications

🏗️ Building and structural setting-out
🛣️ Road centerline and edge offsets
📍 Column and footing positioning
🚰 Boundary and utility layouts
📐 Construction alignment and control points

Important: Always verify the Total Station's centering, levelling, orientation, prism/target setup and measurements before marking permanent points. Actual site setting-out should follow the approved survey drawings and project specifications.

🚗WHY YOU LOSE CONTROL IN CURVES

🌟Taking a curve safely is all about maintaining the right balance between speed, tyre grip, braking, weight transfer, and road geometry.

☄A small mistake can quickly turn into skidding or loss of vehicle control.

🔹 1. Excess Speed

Entering a curve too fast increases the lateral force required to keep the vehicle on its path. If the available tyre grip is insufficient, the vehicle may skid.

Higher speed = Higher risk

🔹 2. Wet or Loose Road Surface

Rain, mud, gravel, sand, and other loose materials reduce tyre–road friction. With less available grip, the vehicle can lose traction more easily.

Less friction = More possibility of sliding

🔹 3. Braking Inside the Curve

Heavy braking while cornering can shift load toward the front axle and reduce available rear-tyre traction. This can contribute to oversteer or instability.

✅ Best practice: Reduce speed and brake smoothly before entering the curve whenever possible.

🔹 4. Incorrect Camber

Proper road camber helps with drainage and can support stable vehicle movement through curves. Poor or inappropriate cross-slope design can negatively affect handling and safety.

🛣️ Safe Driving Tips

• Slow down before entering a curve.
• Steer smoothly and avoid sudden movements.
• Keep tyres properly inflated and in good condition.
• Avoid harsh braking while turning.
• Adjust your driving to weather and road conditions.
• Never assume every curve can be taken at the same speed.

📌 Key Point

Safe cornering depends on SPEED + FRICTION + WEIGHT TRANSFER + ROAD GEOMETRY.

⚠️ Always follow posted speed limits and drive according to actual road conditions.

Drive safe. Arrive safe. 🚘
