An architectural drawing is a technical drawing of a building (or building project) that is used by architects to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to enable a building contractor to construct it, as a record of the completed work, and to make a record of a building that already exists.

Calculation of Loads:

• Dead load calculation:

(a) Dead load of column:

Height of column : (slab thickness x 2) + (Height of each floor x 2) = (0.25 x 2) + (3 x 2) = 6.5 m

Total volume of concrete = 0.3 x 0.3 x 6.5 = 0.585 m^3

Unit weight of RCC = 25 kN/m^3

Dead load on column = 25 x 0.585 = 14.62 kN

(b) Dead load of beam:

Total volume of concrete = 0.3 x 0.45 x 1 = 0.135 m^3

Dead load of beam = 25 x 0.135 = 3.375 kN

Unit weight of building materials as per IS 875 (Part 1)

(c) Dead load of slab:

Slab is always designed for span 1m.Hence , assume size of slab = 1m x 1m

Thickness of slab = 0.25m

Self weight of slab = 1 x 1 x 0.25 x 25 = 6.25 kN

(d) Dead load of walls:

External wall: Thicknes = 0.23 m , Unit weight of brick wall= 20 kN/m^3, Height of wall = 3m

Load of wall on beam = 3 x 0.23 x 20 = 13.8 kN

Internal wall: Thickness = 0.15 m

Load of wall on beam = 3 x 0.15 x 20 = 9 kN

• Live load calculation:

According to IS 875 (Part 2)

Following are the live loads for different buildings:

Sl. No.	Description	UDL Load (kN/m2)	Concentrated Load (kN)
1.	Bathrooms and toilets in all types of buildings	2	1.8
2.	Living and bed rooms	2
3	Office rooms in
	(i) Hostel, hotels, hospitals and business building with separate store	2.5	2.7
	(ii) In assembly buildings	3	4.5
4.	Kitchens in
	(i) Dwelling houses	2	1.8
	(ii) Hostels, hotels and hospitals	3	4.5
5.	Banking halls, class rooms, X-ray rooms, operation rooms	3	4.5
6.	Dining rooms in
	(i) Educational buildings, institutional and mercantile buildings	3	2.7
	(ii) Hostels and hotels	4	2.7
7.	Corridors, passages, stair cases in
	(i) Dwelling houses, hotels, and hostels	3	4.5
	(ii) Educational, institutional and assembly buildings	4	4.5
	(iii) Mercantile buildings	5	4.5
8.	Reading rooms in libraries
	(i) With separate storage	3	4.5
	(ii) Without separate storage	4	4.5
9.	Assembly areas in assembly buildings
	(i) With fixed seats	5
	(ii) Without fixed seats	5	3.6
10.	Store rooms in educational buildings	5	4.5
11.	Store room in libraries	6 for a height of 2.24 2kN/m2 for every 1m additional height	4.5
12.	Boiler rooms and plant rooms in
	(i) Hostels, hotels and hospitals, mercantile and industrial buildings	5	4.5
	(ii) Assembly and storage buildings	7.5	4.5

• Wind load calculation:

Wind load is designed only when the height of building exceed 10 m .

The height of building design is 6m which is less than 10m so, we will not consider wind load.

Codes referred :

IS 875:1987 (PART 1) for Dead load

IS 875:1987 (PART 2) for Live load

IS 875:1987 (PART 3) for Wind load

IS 456:2000 for RCC

Result:

• The plan is designed by considering Vastu Shastra concept
• The load calculations are done as per IS code consideration.
