Excavation. Once the layouts of the construction points and grid line have been completed, the excavation works begin. The Excavation depth depends on the recommendation by the soil investigation report. But it’s safe to say that the minimum excavation level for the footing to rest should stick to 1 Meter below the ground level. Excavation […]
Compacting and Laying PCC. Compacting of the excavated surface should perform once we reach the desired excavation level. A layer of crushed gravel and sand is added during the compaction. Standard compaction procedure the final compacted layer should be checked in order to reach the desired degree of compaction is not less than 95 %
Foundation Bars and Column Starter Bars. Once the laying of PCC has been set up, the TMT bar work for foundation and foundation Beams are the next activity. In this stage the reinforcement of foundations is being prepared according to the structural drawings along its formworks . The proper and standard concrete cover should be
Concreting of Foundation. The concrete to be poured should be properly vibrated for the concrete specifically the aggregates to fully spread into the footing for column. Installation of column reinforcement on the previously installed column starter but should be continued after this procedure. A proper concrete cover should be considered before closing the formworks. Here
Backfilling and Compacting. Once the substructure like foundation structures including the solid blocks have been installed completed backfiling and compacting should take place. Backfilling and compacting should be done partially to make sure that the required degree of compacting has been met until reaching the bottom of the tie beam level. Here are the some
Concreting of Slab. Once the ground floor columns have been cast it’s time to prepare the project for beams and suspended slab reinforcement activity. Like any other structural members beam and slab reinforcement should be followed strictly. Shuttering or formworks for slab and beam should be properly checked before concrete pouring Here are the slab
Formwork of Slab Beam and Slab. When the column casting has done the beam and slab shutting has starts . In this step rainforcement also has done and cover provied as same in structural drawings. Here are the Formwork work, done by Maa kalika infrastructure, in the presence of Civil Engineer Mr. Bhaskar Prasad.
Rebaring of Column and Plinth Beam Rainforcement When the footing of concrete in was done the next step to consider is rebaring of column and beam. In case of rebaring the standard development length of bar should be measured. The standard development length is considered 50 times more then the the rod diameter. Here are

Formwork of Column and Concreting. When the rebaring of column has done the formwork and work begin. Proper cover should be observed during this procedure. A vibrator should be properly vibrated in columns.
Shuttering oiling for good smooth finishing Using Suttering oil before before casting a column,slab,beam, etc.it helps ensure a successfull and high quallity concrete casting process.It helps easy removal of the shuttering at time of deshuttering the member whereas the oil must be of good condition. Not too much burnt oil has to be used.
