ABOUT THIS VIDEO
In this video Er. Vijish Shinde discuss about Detail Construction Process step by step Upto Project Hand over.
The 'construction process' (sometimes called the 'construction stage') is the physical processes of building, landscaping or refurbishing plus all the associated activities, such as demolition, site clearance, administration and so on.
The process of calculation of quantities and COST of various items in connection with the construction project is called an estimate.
The phases of building construction can typically be divided into five phases: initiation, planning, execution, monitoring, and the completion.
IN THIS NOTES, WE WILL KNOW ABOUT COMPLETE BUILDING ESTIMATION FROM SITE CLEANING TO PROJECT HANDOVER.
The process of site cleaning is much more complicated than a typical cleaning job due to the nature of the materials being removed from the work site. There will grass, trees, vegetation, disposal & unserviceable materials are in the site, so these items are to be cleaned before construction process is to be done. In site cleaning measurements are done in area (sqm) up to two decimal places, & take 1 m extra in all direction for site cleaning.
Excavation is the process of moving earth, rock or other materials with tools, equipment or explosives.
➢ All excavation operations shall include excavation and getting out the excavated materials. The excavation shall conform to the lines & levels shown in the drawings.
➢ Excavation can be done by mechanical or manual means as per choice/ ease of contractor and conditions of site. ➢ Excavation where directed by the Engineer-in-Charge shall be securely fenced and provided with proper caution signs, conspicuously displayed during the day and properly illuminated with red lights during the night to avoid accidents.
➢ Pumping out of water during excavation shall be measured in cum and shall be payable one time for the entire operation of excavation. Height for calculating volume shall be based on the difference of water level and the bottom level of the excavated pit.
➢ Excavation can be calculated in (cum) up to three decimal places as per given drawing or modified dimensions, & take extra 100mm in all each side. ➢ Any damages done by the contractor to any existing work shall be made good by him at his own cost.
Sand filling is done in footing we can’t place concrete directly on the earth soil because it affects the mix design.
➢ If the footing is placed directly on the earth surface, if small amount of vibration on the earth (during an earthquake) will make structure collapse. Sand is minimizing the resistance.
➢ Calculating quantity of sand filling in volume unit is in (cum).
➢ We have done sand filling 4” to 8”. (i.e. =100mm to 200mm height).
PCC is done below footing for provide footing hard base when we apply foam work it make stable base.
➢ Pcc height is taken 4” to 6” (i.e., 0.1m to 0.15m)
➢ It may calculate volume of pcc in (cum).
Footing is one of the most important parts of a structure which transfer loads of the structure to the underlying soil. The selection of footing depends upon the following steps.
➢ The depth of the soil at which safe bearing strength exists.
➢ The type and condition of soil.
➢ The type of super structure.
❖ Their are two types of foundation.
➢ Shallow foundation ➢ Deep foundation
1. Shallow foundation :- In this foundation depth is less then or equal to width. e.g.:- rectangle footing, trapezoidal footing, step footing, strap footing, combined footing, mat/raft.
1. Deep foundation :- In this foundation depth is more then its width. e.g. :- pile footing.
