Recognition Scheme >

Temporary Site Laboratories

Overview

Civil engineering projects have temporary site testing facilities for the testing of building materials such as fine aggregates, coarse aggregates, and concrete cubes at construction sites. Testing of all these building materials is normally being done at temporary construction sites which is required across the construction industry in which the project size is more than 50,000 Sq.ft area (Constructed area). Site testing laboratory which is having area of 50,000 sq. ft or more can apply for this recognition program.

To ensure the quality and competency of the temporary site testing laboratories, NABL has launched a recognition scheme for such laboratories. This scheme is voluntary and an independent quality assurance scheme, which is not covered under APAC & ILAC MRA.

This recognition scheme is developed for the testing of the following basic building materials at the construction site, with the defined test parameters for the following materials.

  1. Fine Aggregates
  2. Coarse Aggregates
  3. Concrete
This recognition scheme will give confidence in the test result/report issued by temporary site testing laboratories, which is very much necessary to ensure the quality of materials used for building construction.
The scheme is applicable only to temporary site testing facilities. Mobile testing facilities are not included in this scheme at present.

The competency of the temporary site testing laboratory will be determined through the results of the onsite assessment (including test witness), participation in proficiency testing program (PT), and records in accordance with this specific criteria.

The temporary site testing laboratory will get recognition for the project duration (however it will be maximum of 5 years). The starting date of the project will be the commencement certificate from the authority and end date will be getting the occupancy certificate from the authority. The onsite surveillance will be conducted in every 10 months & before 12 months. In case of shorter project duration surveillance will be conducted in 6 months. The Unannounced assessment may be conducted during the recognition period.

Application Fee (non-refundable, to be paid along with the application) ₹ 11,000
Annual Recognition Fee (per year from the date of recognition) Note: Annual Recognition fee is payable in advance and is non-refundable and non-adjustable. ₹ 24,000
Overhead Charges ₹ 11,000
Assessment Charges (payable after the completion of the assessment visit to the lab) Comprising of
  • Travel, Boarding, Lodging
  • Honorarium for NABL Assessors
  • Overhead Charges
Travel, Boarding and Lodging expenditure The lab will make the travel arrangements for assessors as per the following entitlements. Any travel or boarding and lodging beyond the following entitlement shall be agreed upon in advance by the lab under the intimation to NABL. The laboratory shall not make any cash transactions/money transfers in any mode etc. with the assessor. Also, lab shall ensure the safety and security of the assessor visiting their premises for conducting assessments. Travel If the journey is more than 300 km, travel to be made by Air in economy class (Apex fare). If the journey is up to 300 km, travel may be made by train in 2nd AC Class / AC Chair Class or by AC Bus. If the outstation journey is made by own car, the reimbursement will be restricted to 2nd AC class fare by train. Travel within the city by taxi will be reimbursed on the production of receipts/bills. In the absence of taxi bills or travel by own car within the city, claim will be reimbursed @ ₹ 15 per km. Any other relevant expenses during the travel will be reimbursed only on the production of receipts/bills. Boarding and Lodging A single occupancy AC accommodation to be provided for each Assessor in a reasonably good hotel/guest house and arrangement for local transportation from temporary residence to the lab site and airport/railway station/bus stand to be made. The lab shall pay for meals of the Assessor/ Observer during the stay, within reasonable limitations. Note: The travel, boarding & lodging for Observer/ NABL Officials joining assessment as Observer, shall be borne by NABL.
Honorarium for NABL Assessors
– by Lead Assessor ₹ 5,500 per day
– by Technical Assessor/ Expert ₹ 5,000 per day
