Measurement of Building Work (a)

MEASUREMENT OF BUILDING WORK (A)

Task -01

1.1 Any construction work measurement is getting an important place. So we should know important and principles of measurements. We want to get correct and accurate measurement for this we use SMM7 this standard method of measurement provides a uniform basis for measuring building works and ombidies the essentials of good practice. Bills of quantity shall fully describe and accurately represent the quantity and quality of the works to be carried out. More detailed information than is required by these rules shall be given where necessary in order to define the precise nature and extent of the required work.

SMM7’s including following type of information Use of the tabulate rules 1. Generally 2.Classification table Quantities

1. Supplementary rules Descriptions Drawing information Catalogued or standard components Work of special types Procedure where the drawn and specification information required by these rules in

not available Fixing, base and background Composite item Work not covered Symbols and abbreviations Work to existing buildings General definition

For this information we can take measurement easily and quickly so SMM7 is more important for building works.

Principles of measurement practices

For the measurement quantity surveyor using by following stationeries this are called as surveyor’s stationeries.

the work time only after working these are removed or finished so that has cost such as,1.Water for work2.Supervision3. Temporary work.

Temporary road Hats / office Electric supply

4. Scaffolding.

2).Sectional trade bill

There would be a number of sectional trade bills in accordance with the scope, or complexity of the project. All the measured work in according with the SMM7 will be inserted in to sectional trade bills, such as,

*Bill No.2D-Ground work

*Bill No.3F-Masenry

*Bill No.4E-In-site concrete etc.

3).Preambles.

Preambles are clauses usually inserted at the head of each work section bills, and principally contained descriptions, together with another relevant information of which the contractor should be aware in pricing. Inserting the preamble in the BOQ the length of the work descriptions are reduced and the specifications is not necessary if they provide the information. Another procedure is to combine all preamble clauses in a separate bill, following preliminaries.

Functions of preambles

۩ Specify quality of materials.

۩ Specify the standard of the workmanship required .

۩ Assist in pricing measured work.

۩ Repetition of same information item by item will be avoided and hence the work

Descriptions will be more concise.

4).Money provision.

BCAS Page 10


There are two types of money provisions that are inserted in to a BOQ

1. Prime cost sums.

The term “Prime cost sum” (PC sum) is a sum provided in the bill of quantities for works or services to be executed by a nominated subcontractor, or for materials or goods to be obtained from a nominated supplier such sums are exclusive of any profit required by the main contractor and provision is made for its addition following the Pc sum general and special attendance by the main contractor on nominated subcontractors is provided as an item in the preliminaries bill. These can be entered either as fixed or time related charges.

A Provide the PC sum of Rupees 200000for the

Supply of 12 Nr sanitary appliances, to be

Obtained from M/S sanitaryware ltd. 200000 00

B Add main contractor’s profit

C Provide the PC sum of Rupees1500000 of or

The installations of a lift to be exacted by a

Nominated sub-contractor. 1500000 00

D Add special attendance %

E Add Main contractor’s profit %

2. Provisional Sums

Where the work cannot be descried and given in accordance with SMM (SL) rules, It shall be given as a provisional sum and identified as for either defined or undefined work. In defined work items a description and indication of the amount of work. Can be given and the contractor will be deemed to have made due allowance in programming, planning and pricing the preliminaries. Whore these details cannot be supplied the work is classified as undefined and the contractor will be deemed not to have made any allowance in programming, planning and pricing the preliminaries. Work by local authorities and statutory undertaking are the subject of provisional sums.

A Allow the general provisional sum of Rupees

100000 to cover the cost of any unforeseen

Works. This sum is to be expanded the

discretion of the Architect/Engineer. 100000 00

5).General summary.

There general summary is to provide monetary collection at the end of each group of work sections such as D-Ground works, F-Masonry the total of which are then trans tarred to the final summary.
