🔹 Understanding the Contractor’s Delay Claims Process with FIDIC 2017 🔹

In construction, delays are often unavoidable. According to the 2017 FIDIC Red Book, contractors can submit claims for additional payment or time extensions if they encounter delays caused by the employer. Here’s a breakdown of the process:

1- Identify the Delay Event: Recognize any event impacting the critical path and compare the original and actual schedules.

2- Determine Entitlement: Verify if the delay is excusable or compensable based on contract terms.

3- Submit Notice of Claim: Submit a notice within 28 days of the delay event to maintain eligibility for compensation.

4- Engineer’s Initial Response: The engineer has 14 days to respond to the claim with their preliminary assessment.

5- Fully Detailed Claim: Submit a comprehensive claim with all supporting documents within 84 days.

Also helps contractors manage delays professionally, ensuring clarity and compliance with FIDIC standards.

🏷Unlike most retail companies that only require simple line items list on invoice Most construction businesses is complex & have to provide collection of detailed documents, providing proof of labor & materials supplied within billing period

🚧𝐖𝐡𝐚𝐭 𝐈𝐬 𝐂𝐨𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐨𝐧 𝐈𝐧𝐯𝐨𝐢𝐜𝐞?

🚧𝐈𝐧𝐯𝐨𝐢𝐜𝐢𝐧𝐠 𝐈𝐧 𝐂𝐨𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐨𝐧 𝐏𝐫𝐨𝐣𝐞𝐜𝐭

Invoicing process vary based on contract agreed upon owner & contractor, but larger construction projects will most likely be on progress billing structure

Contract type(Lump sum, T&M, etc.) ultimately decides how & when to make payment

🚧𝐏𝐫𝐨𝐠𝐫𝐞𝐬𝐬 𝐁𝐢𝐥𝐥𝐢𝐧𝐠

Pay contractors based %work completed, allow client to control cash outflows to match project progress Typically, issuers make payment on monthly schedule & at certain completion% (30%,60%, etc.)

🚧𝐏𝐞𝐫𝐜𝐞𝐧𝐭𝐚𝐠𝐞 𝐎𝐟 𝐂𝐨𝐦𝐩𝐥𝐞𝐭𝐢𝐨𝐧(𝐏𝐎𝐂)

Accounting Method for long-term projects where Revenue & Expenses recognized based on periodical work% complete(Monthly basis)

Most common way to determine project’s POC is 𝐂𝐨𝐬𝐭-𝐓𝐨-𝐂𝐨𝐬𝐭 𝐅𝐨𝐫𝐦𝐮𝐥𝐚 by comparing estimated & actual project costs
%Complete= Total Cost To Date/Total Cost Estimated

Recognized Revenue = %Complete x Contract Amount

👉Plumb Bob (ቱምቢ)

💫A plumb bob, plumb bob level, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line.

It is a precursor to the spirit level and used to establish a vertical datum.

It is typically made of stone, wood, or lead, but can also be made of other metals.

The instrument has been used since at least the time of ancient Egypt to ensure that constructions are "plumb", or vertical.

It is also used in surveying, to establish the nadir with respect to gravity of a point in space.

It is used with a variety of instruments (including levels, theodolites, and steel tapes) to set the instrument exactly over a fixed survey marker or to transcribe positions onto the ground for placing a marker.

👉COMPONENTS OF A BRIDGE

🏷What is a bridge ?

⏺A bridge is a structure constructed along a traffic crossing or over obstacles such as river, to make movement of vehicles easier.

⭐️COMPONENTS

▶️The bridge components can basically be divided into two parts or discuss under two headings

🚧A. Sub - structure components

🚧b. Super - structure components

💫Sub - structure are the components below the bearing , on the other hand, components above the bearings constitutes superstructure.

⏺There are various types of bridge being constructed as a result of the technological developments, hence the components of each bridge solely depends on the type of construction made, but the major components for a convectional type of bridge are:

a. Abutments
b. Wing walls
c. Piers
d. Pier cap
e. Bearing
f.  Foundation

❇️1. ABUTMENTS:  Bridge abutments are vertical supports at the bridge ends.

⏺They are the end points of a bridge components which acts as a retaining walls in resist earth pressure in the approach areas .

❇️2. WING WALLS : wing walls are located very close to the abutments.

⏺They are act as a retaining walls in resisting earth in the approach areas.

❇️3. PIER:  This part of the bridge components are vertical supports provided between bridge span.

⏺Their main function is to transfer the loads coming on the superstructure to the foundation.

❇️4. FOUNDATION: Foundation is the key element of a bridge components.

⏺The function of any foundation is to transmit to the subsoil the loads of the structure.

⏺Similarly, the function of the bridge foundation is to transfer the loads coming on substructure and superstructure to a large area and hard strata.

❇️5. BEARING: Bridge bearings are components of the bridge that provides a resting surface between the bridge piers and the bridge deck.

⏺The main function of the bearing is to control movements and reduce the stress involved.

❇️6. DECKING: A bridge decking forms the surface for traffic, it is supported by beams and girders.

👉Why Do Concrete Cracks Occur?

💫The causes of cracking in concrete can be summarized as follows:

1. Thermal Expansion and Contraction: Concrete expands and shrinks in response to temperature changes.

2. Excessive Heat of Hydration: High temperatures during the curing process can lead to cracking.

3. Delayed Curing: Postponing the curing process can weaken the concrete.

4. Improper Casting: Issues during the casting process can contribute to cracks.

5. Settlement of the Structure: Natural settling can create stress, leading to cracks.

6. Heavy Loads: Excessive weight placed on the concrete can cause it to crack.

7. Water Loss: Shrinkage occurs when water evaporates from the surface of the concrete.

8. Insufficient Vibration: Lack of proper vibration during placement can result in air pockets and weak spots.

9. Inadequate Cover for Reinforcement: Insufficient coverage of reinforcement can result in damage.

10. High Water-Cement Ratio: A higher ratio can increase workability but also raises the likelihood of shrinkage.

11. Corrosion of Reinforcement Steel: Rusting steel can expand and crack the surrounding concrete.

12. Rapid-Setting Mixtures: Some fast-setting options have a higher potential for shrinkage.

13. On-Site Water Addition: Adding water after mixing can negatively alter the concrete's composition.

14. Admixture Overdosage: Excessive use of admixtures can adversely affect concrete performance.

15. Incorrect Admixtures: Using the wrong type of admixture can lead to problems.

16. High Temperatures: Elevated temperatures can accelerate curing and increase the risk of cracking.

17. Low-Quality Cement: Poor-quality materials can compromise the integrity of the concrete.

18. High Absorption of Aggregates: Aggregates that absorb too much water can disrupt the balance of the mix.

19. Improper Mix Design: Errors in mix design can lead to inadequate strength and durability.

20. Issues with mass concrete include casting delays, hydration-induced overheating, temperature differentials, unmonitored temperatures, and inadequate insulation that fails to meet requirements. Other concerns involve the full use of cement without pozzolanic material substitutes.

🏷By addressing these factors, the likelihood of cracking in concrete can be significantly reduced.
