Explanation:

1. Flooring quantity is measured in square meters (m²), which represents the area of the floor.

2. The length and breadth for measuring the flooring are taken as the inside dimensions of the room, from wall to wall of the superstructure. This ensures that the area being measured corresponds to the floor space inside the walls where the flooring material is applied.

3. Height is generally not involved in the calculation of flooring area unless there is a requirement for volume calculations, such as in the case of raised floors or for materials like concrete flooring.

 Additional InformationTypes of Flooring Measurements:

1. For tiled flooring, the measurement is based on the total area covered by tiles, excluding any spaces like doorways or areas not covered by the flooring.

2. For wooden or vinyl flooring, measurements are usually taken from wall to wall, inside the room, and may include allowances for any cutting or wastage.

3. For raised flooring, the area may be calculated similarly to conventional flooring but might involve adjustments if the height of the floor needs to be factored into the design or material estimate.

Explanation:

To calculate the total quantity of brickwork, we need to find the volume of the wall. The volume is calculated by multiplying the length, width, and height of the wall.

Given:

• Length = 7 m

• Width = 0.3 m

• Height = 3 m

Formula

Volume = Length × Width × Height

Substitute the values:
Volume = 7 m × 0.3 m × 3 m = 6.3 m³

So, the total quantity of brickwork required is 6.3 m³.

Explanation:

As per IS 1200 Part I, which deals with the measurement of building works, the measurement guidelines are:

• Length: To be measured to the nearest 0.01 meters (1 cm).

• Area: To be measured to the nearest 0.01 square meters (1 cm²).

• Volume: To be measured to the nearest 0.01 cubic meters (10 liters).

Additional InformationIS 1200 Part I - General Principles of Measurement of Works in Building Construction:

1. Purpose:

   • IS 1200 Part I provides the standard methods for measurement in building construction to ensure uniformity and consistency in the way work is measured and reported.

   • It helps avoid discrepancies in quantity calculation and provides guidelines for accurate recording of measurements on construction sites.

2. Application:

• IS 1200 Part I is applicable to all building works, including residential, commercial, industrial, and infrastructural projects.

• It is used by contractors, engineers, quantity surveyors, and project managers to ensure that the work is measured consistently and in accordance with established norms.

Explanation:

 (as per IS 3861:2002 – Method of Measurement of Plinth, Carpet, and Rentable Areas of Buildings):

• According to IS 3861:2002, the plinth area of a building is defined as the built-up covered area measured at the floor level of the basement or any storey.

• In common construction practice, it is measured at the floor level of the ground floor, which is the finished floor level of the building.

Additional Information.

1. Top of the damp-proof course

   • It is a moisture barrier just above the ground level.

2. Mid-level of the foundation

   • The foundation level is beneath the ground and not the reference point for measuring plinth area.

3. Top of the plinth

   • The top of the plinth refers to the level at the top of the foundation wall or base, but the plinth area measurement is considered at the top of the damp-proof course.

Concept:

According to IS 1200 (Part 8)

Wire netting used as encasement shall be described (including meshes and wires) and shall be measured in square metres.

Steel rolling shutter/grills shall be described and measured in square metres. The width shall be measured as the outer distance between the backs of the two guide channels of the rolling shutters and the height shall be the distance between the still and the centre of the hood cover.

Gates shall be described and enumerated or measured in square meters; hangings, guide rails and fastenings shall be described and included with item.

The mass of steel sheet, plate and strip: rolled steel sections. Steel rods, steel reinforcements, and steel strips; forged steel, steel casting, and steel tubes shall be taken from relevant Indian Standards. So these are measured in kg.

Site perforated pipes shall be described and measured by mass in kilogram. Deductions for perforations/slots shall, however, be made if its area exceeds 0·02 m².

Explanation:

General rules for measurement are:

All works shall be measured subject to the following tolerances:

(i) Dimensions shall be measured to the nearest 0.01 meter.

(ii) Areas shall be measured to the nearest 0.01 sq.m.

(iii) Cubic contents shall be worked up to the nearest 0.01 cum.

Except: 

1. The woodworks should be measured nearest to 0.002 m.

2. Thickness of slab which shall be measured to the nearest 0.005 m.

3. Structural steelworks to the nearest 0.001 m. 

4. Thickness of roadwork (where the thickness is less than 200 mm) to the nearest 0.005 m.  

Explanation:

The capacity of doing work by artesian or skilled labour in the form of quantity of work per day is known as out turn of the labour.

Concept:

Central line method

It is one of the methods for preparing an estimate.

Calculation of length of the wall is done first, and then multiply it with the breadth and depth of the wall to find out quantity.

This is a method that is suitable for rectangular, circular buildings having no inter or cross walls. Hence it is suitable for a wall having the same width.

Calculation:

Center to center length of wall = 5 + 0.3 = 5.3 m

Center to center width of wall = 4 + 0.3 = 4.3 m

So, Total centre line perimeter = 2 × 5.3 + 2 × 4.3 = 19.2 m

Total volume of brickwork = Total center line perimeter × width of wall × height of room - Volume of door opening

Concept:

Dry volume of cement mortar = 1.33 × wet volume of cement mortar

Bulk density of cement = 1440 kg/m3 

Weight of 1 bag of cement = 50 kg

Calculation:

Given, L = 5 m, H = 3.5 m, T = 0.3 m, Plaster thickness = 0.012 m

Plaster required for both side of wall = 2 × 5 × 3.5 × 0.012 = 0.42 m3 

Dry volume of cement mortar = 1.33 × 0.42 = 0.5586 m3 

Volume of cement required = 0.5586/4 = 0.13965 m3 

Cement bags required = 0.13965/50 × 1440 = 4 bags

 The capacity of doing work by artesian or skilled labour in the form of a quantity of work per day is known as outturn of the labour.

Explanation:

Lead:

• The distance between the source of availability of material and the construction site is known as Lead
• Lead is measured in km
• The cost of conveyance of material depends on lead

The environment lead on the metalled roads are arrived at by multiplying by a factor as follows:

•  For Sandy tracks – Lead × 1.4
•  For metal tracks – Lead × 1.0
•  For cartze tracks – Lead × 1.1

Explanation:

Deduction in plastering are made in the following manner:

i) No deduction is made for ends of beams, posts, rafters, purlin, etc.

ii) No deduction is made for opening up to 0.5 m2 and no addition is made for jambs, soffits, and sills of these openings. 

iii) For opening more than 0.5 m2 and up to 3 m2 the deduction is made for one face only. No addition for jambs, soffits, and sills of these openings.

iv) For opening above 3 m2 the deduction is made for both faces of openings and the jambs, soffits, and sills shall be added.

Explanation:

Material statement: The total quantities of all the items of materials required for the completion of the construction is shown in Material statement.

Bar bending schedule: Bar Bending Schedule, commonly referred to as “BBS” is a comprehensive list that describes the location, mark, type, size, length and number, and bending details of each bar or fabric in a Reinforcement Drawing of a Structure.

Work charged establishment: The work charged establishment will include the temporary establishment as are employed for the execution or the immediate technical supervision or departmental stores in connection with the specific work.

Explanation:

The quantity of work which can be done by an artisan for trade working of 8 hours is known as out - turn work.

The outturn for different types of work are as follows:

1. Sawing of softwood = 5.5 m2 per mason per day

2. Earthwork in the excavation in foundation trenches = 2.10 m³ per mason per day.

3. Cement concrete work = 5 m³ per mason per day.

Concept:

The trapezoidal formula is given as,

\(V=\frac{L}{2}\left[ \left( {{A}_{1}}+{{A}_{n}} \right)+2\left( {{A}_{2}}+{{A}_{3}}+\ldots +{{A}_{n-1}} \right) \right]\)

Calculation:

The section across the embankment would be trapezoidal in shape.

For extreme edge (1): Top Width = 2 m, Heigth = 3, and

Bottom width =  2 + 2 × 3 + 2 × 3 = 14 m

\(⇒ A_1 = \frac{Top\;width+Bottom\;width}{2}× h=\frac{2+14}{2}× 3=24\;m^2\)

For extreme edge (2): Top Width = 4 m, Heigth = 5,

Bottom width = 4 + 2 × 5 + 2 × 5 = 24 m

\(⇒ A_2 = \frac{Top\;width+Bottom\;width}{2}× h=\frac{4+24}{2}× 5=70\;m^2\)

The volume of earthwork \(\Rightarrow V = \frac{L}{2}\left[ {\left( {{A_1} + {A_2}} \right)} \right]=\frac{100}{2}\left[ {\left( {{24} + {70}} \right)} \right]=4700\) m³.
