Method Statement- Works to Build the Manhole in the lowest Basement

Hello Friends! Welcome to my blog. My name is Dipak Varsani, and I am the author of madaboutconstruction.com. I am a Civil Engineer by profession, and I have taken the journey as a Site Engineer in my company.

In this blog, we will discuss Method Statement which I had to prepare and got approved from an Engineer in my recent project to resolve the rainwater pipe blockages issue and for future maintenance if the same problem arises again. The pipe was getting blocked frequently, and the reason may be;
Pipe Size:- If the pipe size is too small, it can get choked up easily. In my case, the pipe size was 100mm.
The slope of pipe:- To flow the water with gravity force the minimum required slop is 1% (10mm in every 1000mm), and this is what we have provided during placement of rainwater pipe in our project.
Distance:- The distance from the bend in-floor up to Intermediate manhole or Petro Inter-septics tank or any other tank or manhole. If the distance is long then debris of stuff get accumu…

What is waffle slab?

Hello Friends! Welcome to our blog. We are Dipak Varsani and Stann Maina. We are Civil Engineer and building manager by profession respectively. We are the authors of madaboutconstruction.com. Today we want to mesmerise you with this new slab technology in building construction.


What is Waffle Slab? The slab with the holes underneath giving an appearance of waffles is referred to as the waffle slab. The waffle slab is usually used where large spans are required so that the column interfering with space can be avoided and where thick slabs spanning between wide beams are required. Wide beams are used instead of high beams so that the interference of the beam with the future services can be avoided.
Why have a waffle slab? Waffle slabs are relatively lighter and stiffer than their counterpart flat slab, they are also faster to cast than their counterpart. They also use 25% less reinforcement steel and 35% less concrete as compared to the flat slab. These percentages are subject to ch…
