This document summarizes an internship project presentation on the construction of a raft foundation and building. It includes details on the raft foundation specifications, column construction process, beam and slab forming and reinforcement, materials used including cement, sand and aggregates, and a timeline for the project. The presentation provides technical information on the construction stages and specifications to complete the foundation and overall building by December 2026.

Specification;
Area of Raft :506.17 m
• Thickness of Raft :550mm
• Grade of Concrete :M25(1:1:2)
• Grade of Steel :Fe500D
• Bottom reinforcement :20mm @110mmc/c (both ways)

5. COLUMN :
• Layout of columns:
Check the location of columns from the datum location. If any deficiency take
place within permissible limits, made adjustments accordingly, otherwise
reconstruction of column is done.
Filling of starters:
Starters make the actual positions for const of column made of mortar or lean
concrete. Thickness varies from 4-6mm. Make the base to shuttering.

• Reinforcement of Columns:
Reinforcement is done as per given in drawings. Check should be made to the
splice length. As the lateral ties spacing varies along the length of column hence
spacing should be properly maintained.
Shuttering of columns;
Shuttering is either made of wooden or steel(Preferably steel). Vertically of
shuttering could be checked by using plumb bob and thread. Cover block must be
provided for better finishing of column.

8. Construction of beam and slab:
• Formwork of beam and slab :
Form work of main beam is first laid on the column, then secondary
beam shuttering is placed. After it, slab formwork is laid.
Shuttering is supported by tubular scaffolding which can be
adjusted later on .

• Reinforcement of slabs :
Firstly reinforcement of beam is done as per given in drawings. Care should be
taken for curtailed bar and maintain the spacing of sttruips. Then steel of slab is
laid down to the required spacing. Top bar and sunken portion should be properly
checked.
Levelling of beam and slab:
After the reinforcement the level of beam and slab are checked
a) Marking with the paint on the column bar at equal level mean of water pipe
b) Joint the all point by means of thread then with the help of tape check the
level of beam and slab. If required adjustment by mean of jack in scaffoldings.
