PWD RATE-2022
effective from 21 June 2022
Annexure-A
NOTES ON PLINTH AREA RATES (PLAR)
1. PLAR are the rates to assess the cost of buildings when detailed architectural and structural design are not available.
2. PLAR are formulated by studying plenty of variables, data, and assumptions only to provide
hints on the cost of construction over a couple of years.
3. A wide range variation of actual cost from PLAR directs to study- (i) architectural & structural
design, (i) site condition, (ii) finish schedule, (iv) decision built up.
4. Exclusive works related to the high density of cost like exclusive ornamental works/cladding are
beyond the scope of PLAR.
5. PLAR never resembles an actual cost; instead, it's a probabilistic cost for fund conformity after a time-dependent tender and agreement procedure to run a smooth project.
6. PLAR costs for buildings are to be assessed after confirming the building category namely
'standard', 'super', and 'special'.
7. 'Special' category for office buildings is to be decided by Chief Engineer, PWD, and Chief
Architect, Department of Architecture.
8. PLAR includes 22.703% extra cost for providing contractor's profit, overhead charge, and VAT.
SCOPE OF PLINTH AREA
The plinth area is the area bounded by the exterior perimeter of a floor or the perimeter formed by joining the lines on the outer faces of columns in the floor, including any area kept opening whatsoever, except the courtyard open to the sky.
SCOPE OF BUILDING CATEGORY
The category of buildings should be understood by the terms standard, super, and special according to the facilities and finishing components provided there. As a guide- The standard category of buildings is made in quality and provided with general basic facilities and finished components are mostly of local materials, bricks, sand, cement, and lime-based but have a hygienic finish in toilets, lavatories, and kitchens.

Notes:
*1. The cost of Retaining walls etc included in Table-4,
*2. Floor height (h) is considered as 3.35 meters (11'-0"),

Notes:
1. For building with more than 1 (one) basement, the member weightage rate shall be taken from the immediate left cell(s) of the selected column for each additional basement.
example: For 20 storied building with 3 no. of basements, values from column-20 to be read on the basis of no. of story
**for the 1st basement- Tk. 4363 to be taken
**for the 2nd basement-Tk. 4493 to be taken from the immediate left column, i.e. from column-21
**for the 3rd basement- Tk. 4602 to be taken from 2nd left column, i.e. from column-22
2. For building with more than 36 stories, the member weightage rate for the topmost floors shall be the same as the top floors rate for 36-storied buildings. And member weightage rate for the remaining floors (not in the table) shall be successively increased by 1.5% from the ground floor for each additional story up to 45 stories.
example: For 38 storied building member weightage for the 36th floor shall be the same as the 34th floor of 36 storied building, i.e. Tk. 274.
Member weightage for the 2nd floor shall be the same as the ground floor of 36 stoned buildings, i.e. Tk. 6137.
Member weightage for the 1st floor shall be the same as the ground floor of 37 storied buildings, i.e. (1.015 x Tk. 6137) Tk. 6229.
Member weightage for the ground floor shall be (1.015 x 1.015 x Tk. 6137) = Tk. 6323
