👉Waffle Slab

🚧Waffle slab is a reinforced concrete roof or floor containing square grids with deep sides and it is also called as grid slabs.

▶️This kind of slab is majorly used at the entrance of hotels, Malls, Restaurants for good pictorial view and to install artificial lighting.

▶️This a  type of slab where we find a hollow hole in the slab when the formwork is removed.  Firstly PVC trays (pods) are placed on shuttering then reinforcement is provided between the pods and steel mesh is provided at top of the pods and then concrete is filled. After concrete sets, the formwork is removed and PVC pods are not removed.

▶️This forms a hollow hole in it in which hole is closed at one end.

▶️The concrete waffle slab is often used for industrial and commercial buildings while wood and metal waffle slabs are used in many other construction sites.

▶️This is one of the types of concrete slabs.

💫Where to use Waffle Slab & Waffle slab details:

⏺A waffle slab has a holes underneath, giving an appearance of waffles.

⏺It is usually used where large spans are required (e.g auditorium, cinema halls) to avoid many columns interfering with space. Hence thick slabs spanning between wide beams (to avoid the beams protruding below for aesthetic reasons) are required.

⏺The main purpose of employing this technology is for its strong foundation characteristics of crack and sagging resistance.

⏺Waffle slab also holds a greater amount of load compared with conventional concrete slabs.

🔰Types of Waffle slabs:

▶️Based on the shape of Pods (PVC Trays) waffle slabs are classified into the following types:

⏹Triangular pod system and
Square pod system

🎲Advantages of Waffle slabs:

❇️Waffle slabs are able to carry heavier loads and span longer distances than flat slabs as these systems are light in weight.

❇️Waffle slab can be used as both ceiling and floor slab.
Suitable for spans of 7m – 16m; longer spans may be possible with post-tensioning.

❇️These systems are light in weight and hence considerable saving is ensured in the framework as the light framework is required

🏷Disadvantages of Waffle slabs:

⏺Waffle slab is not used in typical construction projects.

⏺The casting forms or moulds required for precast units are very costly and hence only economical when large scale production of similar units are desired.

⏺Construction requires strict supervision and skilled labour.

👉TYPES OF CLAIMS

💫Change Order Claims

⭐️Claims for additional compensation or time due to changes in the scope of work.

⏺These changes can be initiated by the owner or discovered during construction.

💫Delay Claims

⭐️Claims for additional time or compensation due to delays. These can be caused by the owner, contractor, subcontractors, suppliers, or external factors such as weather.

💫Disruption Claims

⭐️Claims arising from events that disrupt the planned work sequence, leading to inefficiencies and increased costs.

💫Acceleration Claims

⭐️Claims for additional costs incurred when a contractor is required to speed up work to meet deadlines, often due to delays for which they are not responsible.

💫Differing Site Conditions Claims

⭐️Claims due to unexpected site conditions that differ significantly from those described in the contract documents or reasonably anticipated.

💫Defective Work Claims

⭐️Claims related to the repair or replacement of defective or non-conforming work.

💫Breach of Contract Claims

⭐️Claims arising from one party not fulfilling their contractual obligations, such as failure to pay, poor workmanship, or not meeting deadlines.

💫Termination Claims

⭐️Claims resulting from the termination of the contract, whether for convenience or cause.

💫Payment Claims

⭐️Claims for non-payment or delayed payment for work completed or materials supplied.

💫Force Majeure Claims

⭐️Claims for delays or additional costs due to unforeseen events beyond the parties' control, such as natural disasters or political instability.

💫Warranty Claims

⭐️Claims arising from defects discovered after project completion during the warranty period.

💫Misrepresentation Claims

⭐️Claims based on incorrect or misleading information provided by one party that leads to increased costs or delays.

💫Subcontractor Claims

⭐️Claims made by subcontractors against the main contractor or vice versa, are often related to payment issues or scope changes.

💫Prolongation Claims

⭐️Prolongation claims refer to the claim for additional costs incurred by a contractor due to extending the project duration beyond the originally agreed-upon completion date.

Dynamic cone penetration penetrometer

➪ Dynamic cone penetration
penetrometer or DCP is a tool used
for evaluating the strength of soil on site.
➪ It also helps with monitoring the condition of granular layers and sub
grade soils in pavement section over time.

➪ It can be the right choice for site
with soft soil

➪ it is also applied when the CBR value of compacted soil sub-grade beneath the existing road pavement is to be determined. Continuous reading can be taken down to depth of 800mm or when an extension rod is fitted to be a depth up to 1200 mm.

➪ The DCP is simple and portable
instrument. It consists of hardened conical tip, standard diameter steel
rod , and standard weight hammer (8kg) , which is dropped from the top of the rod against an anvil to advance the tip into the ground.

👉🏾 ይህ መሳሪያ በተለይ ለስላሳ የአፈር አይነት ይመረጣል

የዚህ መሳሪያ ምርመራ ውጤት በ DPI (penteration index) ይገለፃል።
የ አፈሩ DPI ማለት ምን ያህል አፈሩ በመዶሻው እንቅስቃሴ እንደተሰረሰረ ይነግረናል። ይህም በ millimeter ይገለፅልናል። ጠርከር ያለ የአፈር አይነት አነስ ያለ DPI value አለው ማለት ነው ምክንያቱም በቀላሉ ስለማይሰረሰር።

DPI እንዴት calculate እንደሚደረግ ሌላ ጊዜ እናያለን።

DCP test results are expressed in DPI.

DPI is defined as the amount of vertical movement of the DPC cone produced by one drop of hammer. It’s expressed in millimeters. Strong souls have lower DPI than weaker soil.

Next time we will show you how to calculate DPI value.
