#Numerical on Preliminary Estimate of Buildings and Roads

Q₁. Prepare a preliminary estimate of a building project with a total plinth area of all buildings of 1500 sq m. Given that-

i) Plinth area rate - Rs. 950.00 per sq m.

ii) Extra for special Architectural treatment- 1.5% of the building cost.

iii) Extra for Water supply and Sanitary Installations- 5% of the building cost

iv) Extra for internal installations- 14% of the building cost

v) Extra for services- 6% of the building cost

vi) Contingencies-3%

Vii) Supervision charges- 8%

 

Q2. Prepare a Preliminary estimate of a four storeyed office building having a carpet area of 2000 sq m for obtaining the administrative approval of the Government given the following data. It may be assumed that 30 percent of the built-up area will be taken up by the corridors verandahs lavatories, staircases, etc., and 10% of the built up area will be occupied by walls.

(i) Plinth area rate is- Rs. 1050.00 per sq m

ii) Extra due to deep foundation at site - 1% of building cost

iii) Extra for special Architectural treatment- 0.5% of building cost.

iv) Extra for water supply and Sanitary installations- 6% of building cost

v) Extra for Electric installations- 12.5% of building cost

vi) Extra for other services- 5% of building cost

vii) Contingencies-2.5%

vii) Supervision charges- 8%

 

Q₃. Prepare a preliminary estimate of a multi storied office building having a carpet area of 1600 m². The circulation area is 30% of the building and 10%  is occupied by the wall area. The rate is $ 70 per m².The cost of electricity and sanitary installation is 10% of the building cost. External services are taken as 2% of building cost. Contingencies and supervision charge 4% and 5% of overall cost respectively.

Q4. Prepare a preliminary estimate of a building having a plinth area equal to 1600 square meters.

Given that

i. Plinth area rate= $ 200 per m²

ii. Extra for architectural work=  1 ½ % of building cost

iii. For electrical installation= 10% of building cost

iv. For water supply and sanitary installation= 5% of the overall cost

v. Contingencies and supervision charge 4% and 5% of overall cost respectively

Q₅.  Find the preliminary estimate of the road having a length of 10 km. The width of the road is 8 m and the thickness is 0.2 m. The rate per km for the given road is 8,000$. Take 10 to 30 % of the overall cost for supervision and technical services

Q_6. Prepare a preliminary estimate of a multi storied building having a carpet area of 2200 sq. m. 22% of the built up area will be taken up by corridors, veranda, staircase etc. and 14% of built -up area will be occupied by walls.
*Note:-Assume the plinth area rate Rs. 16,000/- per sq. m. and provide for water supply and sanitary fitting and electrical installation, contingencies and other services.

 

Q₇. Prepare an approximate estimate of building project with total plinth area of all building is 80 sqm. and from following data.

Plinth area rate Rs. 40000 per sqm .

Cost of water supply @ 7½%of cost of building

Cost of Sanitary and Electrical installations each @ 7½% of cost of building

Cost of architectural features @1% of building cost.

Cost of roads and lawns @5% of building cost.

contingencies @ 4%

Determine the total cost of building project?

 

Q₈. Prepare the rough estimate for a proposed commercial complex for a municipal corporation for the following data.

Plinth Area = 500m2 /floor

Ht. of each storey = 3.5m

No. of storey’s = G+2

Cubical content rate = Rs. 1000/m3

Provided for a following as a percentage of structured cost water supply & Sanitary arrangement-8% Electrification -6%

Fluctuation of rates - 5%

Contractors profit - 10%

Petty supervision & contingencies- 3%
