ARAHAN TEKNIK ( JALAN ) 16 / 03

AN EFFECTIVE APPROACH TO PREPARE BILL OF QUANTITIES FOR

ENVIRONMENTAL PROTECTION AND ENHANCEMENT

Preface

There is an urgent need for the construction industry to address the issues ofenvironmental problems arising from the accelerated infrastructure develop-ment. In this aspect, Jabatan Kerja Raya (JKR) Malaysia has moved forwardin defining the environmental requirements by incorporating EnvironmentalManagement Plan (EMP) into tender documents. However, the success andeffectiveness of this approach does not rely solely on the EMP but also onthe need to enhance the commitment and awareness of all parties involved,particularly the developers/contractors, designers, consultants, academiciansand decision makers.

It is of utmost importance to produce tender documents which are clear andcomprehensive. A revision on environmental protection and enhancements inJKR Tender Documents has been done by itemising the environmental worksinto the Bill of Quantities to allow contractors to tender a realistic price.

This Arahan Teknik provides changes to the items in the Tender Documentwith regards to the Condition of Contracts, Instructions to Tenderers,Specification to Environmental Protection and Enhancements, Preamble toBill of Quantities, Bill of Quantities and Drawings.

The draft version of this Arahan Teknik had been presented during theNational Engineering Conference of Awam 2001 organized by UniversitiSains Malaysia in February 2002, Seminar on Best Earthworks ManagementPractices in Construction Industry which was jointly organized byConstruction Industry Development Board, Department of Environment andJKR Malaysia in March 2002, and during the Assistant Directors (Road)Meeting in Mac 2002. It was also presented during the Workshop onEnvironmental Consideration in Road Projects in April 2002 organized by theRoad Engineering Association of Malaysia (REAM) and JKR Malaysia.


ACKNOWLEDGEMENT
