National Building Research Organisation (NBRO) receives requests from developers for their building construction activities through Project Approving Agencies such as Urban Development Authority (UDA), Department of, Coast Conservation and Coastal Resource Management (CCD), Central Environmental Authority (CEA) and Sri Lanka Tourism Development Authority (SLTDA) for obtaining a clearance from NBRO for the proposed development activities including pilling and deep excavation. The main objective the clearance is to assess the impacts of a particular proposed development to adjacent properties and surrounding environment especially during the construction of the building. The requirement is enacted by the UDA as per their newly published Gazette. |
The clearance of NBRO is a written statement with comments issued to a developer who submits the request to NBRO, including completed required documents. |
This Standard Operating Procedure (SOP) was developed by NBRO to standardize the activities performed under the Geotechnical Clearances Process. This document will provide step by step procedure for each and every activities of the programme. |
STAGES OF THE APPLICATION |
There are three main types of clearances; |
Since 2013, NBRO and Norwegian Geotechnical Institute (NGI) have joined to conduct studies on ground subsidence and landslide studies. The agreement signed then on technical cooperation was extended later to continue the project "Institutional Cooperation on Mitigation of Natural Disasters due to Climate Change" for the five years from 2018 to 2022.
Over the years, the NGI strengthened technical capacity of NBRO by training staff locally and at the NGI. Every year NGI experts visit and together with NBRO staff, conduct advanced surveys. NBRO staff has been trained in GPR techniques and satellite image processing related to landslide and ground subsidence studies. In addition, NGI donated various equipment including an advanced ground penetrating radar system for subsurface mapping, various antennae for horizontal ground scanning and vertical borehole scanning, automated rain gauges, camera drones for aerial mapping and fast computers with dedicated software for image processing.
Royal Norwegian Embassy (RNE) in Colombo provided financial assistance to this project.
