👉An *approached slab*

💫is a structural element commonly used in civil engineering, particularly in the construction of roadways and bridges.

⏺It serves several essential functions to ensure the longevity and safety of the structure.

🏷Here are the primary functions of an approach slab:

1. Transition Smoothness: The primary purpose of an approach slab is to provide a smooth transition between the road pavement and the bridge deck. This helps to minimize the impact on vehicles moving from the pavement to the bridge and vice versa, reducing discomfort for drivers and preventing damage to the vehicles.

2. Settlement Mitigation: Approach slabs help mitigate the differential settlement between the bridge abutment and the adjoining roadway.

The area around the abutment may settle differently due to the differences in foundation conditions and loading. By bridging this gap, the approach slab prevents abrupt changes in the surface level.

3. Load Distribution: These slabs distribute the loads imposed by vehicles from the roadway to the abutment and the ground below.

This distribution reduces the stress concentrations that could otherwise lead to structural damage or failure.

4. Erosion Control: By covering the area between the bridge and the pavement, approach slabs help protect against erosion caused by water runoff.

This is particularly important in preventing the undermining of the bridge abutment and the road.

5. Maintenance of Road Profile: Approach slabs help maintain the designed profile of the road by preventing the formation of a dip or bump at the bridge-roadway interface.

This is crucial for road safety, as sudden changes in the road profile can be hazardous to drivers.

6. Safety and Comfort: By ensuring a seamless transition, approach slabs contribute to the overall safety and comfort of the traveling public.

They reduce the risk of accidents caused by unexpected changes in road elevation.

7. Durability: The use of an approach slab can extend the lifespan of both the roadway and the bridge by preventing structural damage caused by differential settlement and erosion.

⭐️In summary, approach slabs are vital components in bridge and roadway construction, ensuring a smooth, safe, and durable connection between different structural elements.

👉Advantages & Disadvantages of Cost Planning

🏷Cost Planning (CP) is a statement of how design team proposes to distribute available money among building elements & can be adjusted to design requirement.

⏺Starts with development of a figure (or cost) to allow client to decide whether project is feasible.

💫Early cost planning has major benefits for construction projects.

▶️Is used to monitor & control estimated project construction costs to ensure you get accurate expenditure & progress information at every stage.

💫Cost Planning is the use of Cost Model for "Should-Cost" Forecasting to make informed decisions for:

•Budget Requirement Requests
•Cost Estimations
•Output Quantities
•Capacity Management
•Risk Analysis
•Various Time Frames
•Standard Rates
•Defining Targets to Measure Efficiency & Effectiveness

⏺Quantity Surveyors prove there is added value in getting them involved on the ground level of a new project, rather than at the end of the design process.

✓Advantage Of Cost Planning:

•Early cost checks ensure preliminary estimate is more accurate.
•Better understanding of market conditions.
QS has an in-depth understanding of the property market & access to historical information which can assist developers in evaluating various feasibility options for a particular site or project.
•Saves time & money if the architect of redrawing, quantity surveyor creating budgets & contractor on agreeing amendments.
•Balanced expenditure distribution may produce more rationalized design
•Rational expenditure distribution throughout design is achieved
•Closer alliance between design team assist in understanding each other.
•QS is familiar with design at earliest stags
•Better chance of comparing different projects
•Working drawings are likely to be available sooner
•Cost consideration will be given more attention since QS is involved in early stage of design process.
•Since there is checking system on cost, there is a possibility that fewer changes will be made to BQ. Discussions among designers can be made before production of final design saving time in making an adjustment to any changes to cost & design.
•Cost planning provides basic information on cost comparison between different projects.

✓Disadvantage Of Cost Planning:

•More preparation is necessary for early stages of design
•Architect is likely to be more restricted in his method of working
•QS requires greater knowledge of design factors pricing that affect cost
•Architect & QS are likely to be involved in more work
•Designers may have some limitation in their work style
•QS need to be equipped with past experience & knowledge pertaining to cost & factors influencing cost

🚧 𝗕𝗮𝘀𝗲 𝗶𝘀𝗼𝗹𝗮𝘁𝗶𝗼𝗻 is a passive structural control technique where a collection of structural elements is used to substantially decouple a building from its foundations resting on shaking ground, thus protecting the building's structural integrity.
The main feature of the base isolation technology is that it introduces flexibility into the connection between the structure and the foundation. In addition to allowing movement, the isolators are often designed to absorb energy and thus add damping to the system. This helps in further reducing the seismic response of the building.
There are two basic types of base isolation systems; elastomeric bearings and sliding systems.
In this approach, the building or structure is decoupled from the horizontal components of the earthquake ground motion by interposing a layer with low horizontal stiffness between the structure and the foundation.
The second basic type of base isolation system is typified by the sliding system. This works by limiting the transfer of shear across the isolation interface. Many sliding systems have been proposed and some have been used. One commonly used sliding system called is “spherical sliding bearing" In this system, the building is supported by bearing pads that have a curved surface and low friction. During an earthquake the building is free to slide on the bearings. Since the bearings have a curved surface, the building slides both horizontally and vertically. The forces needed to move the building slightly upwards place a limit on the horizontal or lateral forces.

👉LST Testing?

🚧Low Strain Integrity Testing (LST), also known as Pile Integrity Testing (PIT) or Sonic Echo Test, is a non-destructive test method used to assess the quality and integrity of piles or deep foundations, especially bored piles or driven piles.

▶️The test is designed to detect potential issues such as cracks, voids, reductions in cross-sectional areas, or other abnormalities that may affect the pile's performance.

🏷Purpose of Low Strain Integrity Testing:

Quality Assurance: To verify that the pile has been constructed according to design specifications.

Defect Detection: To detect flaws such as cracks, necking (reduction in diameter), bulging, soil inclusions, or voids.

Length Verification: To estimate the length of the pile if documentation is unavailable or uncertain.

Post-Construction Assessment: To check for damage after installation, particularly for driven piles.

💫How It Works:

LST involves generating low-strain stress waves at the top of the pile and measuring their response.

The process uses the principle of wave propagation, where stress waves reflect off changes in material properties, such as discontinuities or changes in pile cross-section.

💫Equipment Used:

Hammer or Hand-held Impactor: A small hammer is used to tap the top of the pile, generating low-strain stress waves that propagate through the pile.

Accelerometer/Geophone: This sensor is placed on the pile head to measure the velocity of the reflected waves.

Data Acquisition System: The system records the response of the pile (reflected waves) and displays it on a computer screen for analysis.

💫Test Procedure:

1. Preparation:

The top of the pile should be accessible and clean, with a flat, smooth surface to ensure proper wave propagation.

Attach an accelerometer or geophone to the top of the pile.

2. Impact:

A light impact (typically with a handheld hammer) is applied to the pile head.

3. Data Collection:

The stress wave generated by the impact travels down the pile. Any changes in the pile's material or cross-section, such as cracks or voids, reflect part of the wave back to the pile head.

The accelerometer records these reflections, and the data is displayed as a time-domain graph (velocity or displacement vs. time).

4. Analysis:

The time taken for the wave to travel down the pile and reflect back is analyzed to identify any anomalies.

A sharp change in the graph indicates a potential defect or change in material properties.

The pile length can be estimated by measuring the time it takes for the wave to reflect from the pile toe and using the wave speed in concrete.

💫Results Interpretation:

Good Pile: A smooth wave reflection at the expected time, with no intermediate reflections, indicates a pile free from major defects.

💫Defects or Anomalies:

Cracks or Voids: Intermediate reflections (before the wave reaches the pile toe) indicate cracks or voids.

Necking (Reduction in Diameter): A reflection indicating a sudden reduction in the cross-sectional area.

Bulging (Increase in Diameter): A change in wave reflection pattern that suggests an increase in pile diameter or material stiffness.

Pile Breakage: A large reflection occurring much earlier than expected indicates the pile may be broken or has a significant defect at that depth.

💫Advantages:

Non-Destructive: No damage is done to the pile during testing.

Fast and Efficient: Testing can be performed quickly, and results are typically available immediately.
Cost-Effective: Compared to more invasive methods like core drilling, LST is relatively inexpensive.

Limitations:
Shallow Depth Sensitivity: LST is more effective at detecting defects near the top of the pile and may not always identify deeper defects accurately, especially in long piles.

Interpretation Skill: The accuracy of the results depends on the experience of the operator and the complexity of the pile or soil conditions.

Not Suitable for All Piles: LST works best on concrete piles and may not be suitable for piles with highly variable materials or non-uniform cross-sections.

👉Four Main Types of Irrigation Systems

🚧1. Surface irrigating

Ideal for landscapes with medium to fine soil textures, a surface irrigation system can use one of three methods: basin irrigation, furrow irrigation, and border irrigation. Properties with mild or regular slopes are well-suited to surface irrigation. However, one disadvantage to this method is the minimal filtration rate, leading to salt/mineral buildup in the soil.

🚧2. Sprinkler irrigation

In sprinkler irrigation, a standard sprinkler system provides water to plants.

A system of pipes supplies water to the spray heads, which then spray tiny droplets into the area.

Although sprinkler irrigation helps any slope, the water distribution can sometimes become unpredictable in hot or windy weather.

Also, it is typically the most expensive of irrigation methods and consumes a significant amount of energy.

🚧3. Drip irrigation

Drip irrigation, also called micro-irrigation or trickle irrigation, does double duty to preserve both water and nutrients.

Water is applied in the plants’ root zone, from a drip system either above or below the soil. One of the most significant advantages is the ability to customize water drip rates depending on the soil or plant type using individual emitters.

When properly designed, installed, and operated, a drip irrigation system can be the most efficient method available – and result in a beautifully flourishing landscape.

🚧4. Subsurface irrigation

A subsurface irrigation system is one of the most popular options, delivering water underneath the soil.

If the water table is low, trickle or drip devices placed below the below can be used as a “back-up,” watering at the plants’ roots.

Because the water is beneath the surface, this method decreases usage by avoiding evaporation. Depending on the property, setting up and maintaining subsurface irrigation systems can become costly.
