👉The key difference between Bitumen grades 60/70, 80/100, and others lies in their penetration value.

* Penetration Value: This measures how far a standard needle penetrates the bitumen under specific conditions. A higher penetration value indicates softer bitumen.
Here's a breakdown:

🏷Bitumen 60/70:

   * Penetration: 60-70 dmm (decimetres per minute)
   * Characteristics: Harder, more viscous, better for hot climates and high-traffic areas. Offers greater resistance to deformation.

🏷Bitumen 80/100:

   * Penetration: 80-100 dmm
   * Characteristics: Softer, more flexible, suitable for colder climates. More prone to deformation under high temperatures.

📜In Summary:

* Higher Grade (e.g., 80/100): Softer, more flexible, better in cold climates.
* Lower Grade (e.g., 60/70): Harder, more durable, better in hot climates and high-traffic areas.

⭐️Note: The specific application of each grade depends on various factors, including climate, traffic volume, and desired pavement performance.

👉How to evaluate project delays and their impact on schedule

》𝐏𝐫𝐨𝐣𝐞𝐜𝐭 𝐃𝐞𝐥𝐚𝐲𝐬 𝐂𝐥𝐚𝐬𝐬𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧

•Non excusable
•Excusable
-Compensable
-Non compensable

》𝐂𝐨𝐧𝐜𝐮𝐫𝐫𝐞𝐧𝐭 𝐃𝐞𝐥𝐚𝐲𝐬

•Experienced on construction project when 2 or more separate delay events occur during the same time period

•Multiple causes to a critical path delay with both contract parties involved the same critical path delay involved.
In the absence of one party’s cause, the other party’s cause will govern

•Schedule has more than 1 critical path with a separate delay affecting each at the same time (very rare)

-𝐃𝐞𝐥𝐚𝐲 𝐌𝐢𝐭𝐢𝐠𝐚𝐭𝐢𝐨𝐧:

•Contractor has an implied obligation to accelerate to mitigate delays, when possible

•Further/additional acceleration might be possible, but might also have a price tag

•Further or additional mitigation cost needs to be evaluated against time extension cost.

-𝐑𝐞𝐜𝐨𝐯𝐞𝐫𝐲 𝐒𝐜𝐡𝐞𝐝𝐮𝐥𝐞𝐬 & 𝐏𝐫𝐨𝐩𝐨𝐬𝐚𝐥𝐬:

•Requesting a Recovery Proposal to recover from an Owner-caused delay limits Contractor’s right to the added Float in non critical paths created by owner-caused delay

•Unrealistic Recovery Schedules can be used to hide delay Contractor delays & delay concurrency.

𝐃𝐞𝐥𝐚𝐲 𝐐𝐮𝐚𝐧𝐭𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐌𝐞𝐭𝐡𝐨𝐝𝐨𝐥𝐨𝐠𝐲

•Total_Time Schedule Approach
•Adjusted As-Planned Schedule Approach
•Adjusted As-Built Schedule Approach
•Contemporaneous Time Frame Analysis

•Are delays or delay portions that extend into the future
•They are time estimates
•They affect Critical path
•Specifications calls for approval of projected delays (Fragnets) before they can be incorporated into schedule

𝐄𝐥𝐞𝐦𝐞𝐧𝐭𝐬 𝐨𝐟 𝐂𝐨𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐯𝐞 𝐀𝐜𝐜𝐞𝐥𝐞𝐫𝐚𝐭𝐢𝐨𝐧

•Based on owner’s unjustified refusal to grant a EOT or FAILURE TO ACT

•Requires that:
–Cause exists that would justify EOT
–Proper request for a time extension
–Denial of that request
–Demand (Express/Implied) that performance be completed on time
–Actual acceleration

𝐁𝐞𝐬𝐭 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞

•Enforce contract requirement for
-good baseline schedule & schedule updates with narrative for each as required
-Formal notice announce potential delay
-Fragnet showing Critical Path impact -Timely submittal of all the above

•Do not waive contract by your act or failure to act.

•Use “Notice of Event” tool to establish a track record of communication on potential delays
This will reduce surprises at project end

•When scope is added to Critical Path, shift risk to contractor as soon as possible

•Analyze & negotiate delays on monthly basis

•Demonstrate good faith even if Contractor is not cooperating

👉𝑯𝒐𝒘 𝒕𝒐 𝒔𝒆𝒍𝒆𝒄𝒕 𝒕𝒉𝒆 𝒃𝒆𝒔𝒕 𝒅𝒆𝒍𝒂𝒚 𝒂𝒏𝒂𝒍𝒚𝒔𝒊𝒔 𝒕𝒆𝒄𝒉𝒏𝒊𝒒𝒖𝒆?

🏷You would think that with the progress made in software & communication, construction projects would have become more efficient.

However, delay & cost overruns affecting more than 90% of the world’s infrastructure projects.

These delays & cost overruns ultimately lead to disputes between contractor & client.

For any delay analyst, starting point in deciding which methodology to use to assess any delay & its impact, is determined by reference to criteria extracted from the Society of Construction Law Protocol (2nd Edition 2017) (“Protocol”) :

•to review relevant contract conditions
•nature of causative events
•nature of project
•to ensure a proportionate approach, value of project or dispute
•time available
•nature, extent & quality of records available
•nature, extent & quality of programme information available; & forum in which assessment is being made

Protocol classifies way in which critical path is determined & has sub-divided into 3 types:

-Prospectively
-Contemporaneously
-Retrospectively

Why Protocol deems critical path as important, is that it's only delays which lie on critical path that can delay completion & thus qualify for EOT

Protocol (Guidance Part B: Core Principle 11; para 11.4 (d))defines as follows:

1)Impacted As-Planned Analysis:

Prospective in its methodology, predicts effect of certain delay, by inserting event on a model of original baseline programme to determine impact of those activities

2)Time Impact Analysis:

Contemporaneous method, takes into account progress & timing of delay events impacting the works, requires reliable records, including as‐built data to update the programme, including an up-to-date & reliable baseline programme being integral for its function

3)Time Slice Window Analysis:

Contemporaneous method also known as time slice analysis, relies on analysis of contemporaneous progress information is considered to be dynamic as it considers dynamic nature of critical path, breaks construction period into separate time slices & examines effects of delay as it occur

4)As-Planned vs. As-Built:

Contemporaneous method, most basic method of delay analysis & is quick & easy to use and prepare.

No changes are made to the programme as it is a straightforward comparison between planned vs. actual work

5)Longest Path Analysis:

Retrospective method to determine as-built critical path. Delay analyst must develop detailed as-built programme then trace longest continuous path backwards from actual completion date to determine as-built critical path.

6)Collapsed As-Built (CAB) (or But For):

Retrospective method known as But For method, carried out on a single-base as-built programme, relying on a simulation of a “what if” scenario based not on contractors’ intentions, but rather contractor’s actual sequences & durations.

👉Stair

1. Tread Depth
The depth of the stair tread should allow a foot to comfortably rest, typically between 25 to 30 cm.

2. Riser Height
The height of the riser should be convenient, typically between 15 to 18 cm, to ensure easy climbing or descending.

3. Step Width

The width of the stairs should accommodate one or two people, typically at least 90 cm.

4. Handrail
The handrail should be installed at an accessible height, typically 80 to 100 cm above the stair surface.

5. Slip Resistance

The stair surface should have anti-slip materials to prevent accidents.

6. Landing Space
Landing spaces should be provided after every 12 steps for resting.

7. Angle of Staircase
The staircase angle should be appropriate, typically between 30 to 40 degrees, for ease of use.

8. Load Capacity
The staircase should be designed to support the weight of people and potential loads.

9. Headroom Clearance
There should be enough headroom clearance, typically at least 2 meters, to avoid obstruction.

10. Aesthetic Integration
The staircase design should harmonize with the overall architecture of the building.

👉what are the Types of joints in concrete constructions

1)Construction Joints
2)Expansion Joints
3)Contraction Joints
4)Isolation Joints

⭐️1)construction joint :-

⏺A separation provided in a building that allows its component parts to move with respect to each other; a joint where two placements of concrete meet.

⭐️2)An expansion joint or movement joint:-

⏺is an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes

⭐️3)A control joint or contraction 
joint :-

⏺is a joint that is put in the concrete to control cracking. For example, when they sawcut joints into the concrete pavement, these are control joints.

⭐️4) isolation joint

⏺accommodate anticipated differential horizontal and vertical movements that occur between a pavement and a structure.

Their purpose is to allow movement without damaging adjacent structures.

👉Several tests are used for quality and strength of cement, including:

1. Fineness test: This test is used to determine the particle size of cement. The fineness of cement affects its rate of hydration and strength development.

2. Soundness test: This test is used to determine the ability of cement to resist volume change and cracking due to hydration. This test is important to ensure that the cement does not cause expansion or cracking in concrete.

3. Setting time test: This test is used to determine the time it takes for cement to set and harden. This test helps to ensure that the cement has the proper setting time for the intended application.

4. Compressive strength test: This test is used to determine the strength of cement after it has hardened. The compressive strength of cement is important to ensure that it can withstand the loads placed on it.

5. Tensile strength test: This test is used to determine the tensile strength of cement. This test is important for applications where cement may be subjected to tensile stresses.

6. Heat of hydration test: This test is used to determine the amount of heat released during the hydration of cement. This test is important to ensure that the heat generated during the hydration process does not cause cracking or other damage to the concrete.

7. Chemical analysis: This test is used to determine the chemical composition of cement. This test is important to ensure that the cement meets the desired chemical specifications and does not contain any harmful materials.
