The EMP should form part of the Bid Documents and shall be considered alongside the specifications. Thereby the prescriptions detailed in the EMP are mandatory in nature and also contractually binding. The EMP will also equally applicable to sub-contractors including nominated sub-contractors if any. The Contractor will be responsible for the compliance with the requirements of the EMP. With the assistance of the Construction Supervision Consultant (CSC) the “Engineer� on behalf of the Employer the Road Development Authority (RDA) will monitor the compliance of EMP by the Contractor. The bidders are advised to carefully consider the EMP requirements stated under item 2.0 “Construction phase� when preparing the bid and pricing the items of work. The prescriptions and clauses detailed in the EMP are integral component of the specifications for relevant item of work unless separate items are included in the Bill of Quantities. Thus separate payments will not be made in respect of compliance with the EMP. In case the Contractor or his sub-contractor/s fails to implement the EMP recommendations after informing in writing, the Engineer will take whatever actions it is deemed necessary to ensure that the EMP is properly implemented. If the contractor or his sub-contractor/s still fails to comply with EMP requirement, the “Engineer� may levy a penalty based on the level of non-compliance, cost incurred to rectify the damages caused by such negligence and/ or recover the cost from contractor’s payments. The Contractor through an appointed dedicated / qualified Environmental Officer shall assist the Engineer to discharge his duties as required in the EMP implementation by (a) maintaining up to date records on actions taken by the Contractor with regard to implementation of EMP recommendations (b) timely submission of reports, information and data to the Project Management Unit (PMU) through Supervision Consultant (SC), (c) participating in the meetings conveyed by the Engineer and (d) any other assistance requested by the Engineer. 1 Environmental Management Plan Environmental Protection and preventive measures Locations/ Mitigation Institutional Issues Project phase cost Responsibility Implement Supervision 1.0 Advance Works 1.1 Design for culverts, leaderways, silttraps and catch pits (a) RDA should obtain prior consent from relevant authorities such as Locations of - RDA Irrigation Department (ID), Department of Wildlife Conservation existing, proposed (DWLC), Sri Lanka Land Reclaimation & Development Corporation & abandoned (SLR&DC) etc., for any proposed construction works on/at areas belong culverts, to these institutions leaderways, side drains, bridges, RDA should obtain prior consent from relevant public if any land use of proposed silttraps people is likely to be interfered temporarily or permanently by the and gated structures of proposed drainage improvement work. canals, toe walls, roadside downward slopes along the proposed road section are given in Annex - I, (also refer design drawings for culvert locations and proposed drainage management plan) (b) For culverts appropriate designs should be considered to allow overland Refer Annex – I Design -do- flow and sheet flow from the pavement or cross drainage without any existing, proposed cost blocking & abandoned For leaderways appropriate designs should be considered for smooth culverts, flow without any blocking leaderways, side drains, bridges, For silttraps appropriate designs should be considered for trapping of proposed silttraps silt in proper manner and gated 2 Environmental Protection and preventive measures Locations/ Mitigation Institutional Issues Project phase cost Responsibility Implement Supervision For catch pits appropriate designs should be considered in order to structures of drain out rain water without blocking / flooding canals, toe walls, roadside Designed drainage facilities must be capable of disposing of the runoff downward slopes generated in a given water catchment without inundating the road along the proposed road pavement, Pedestrian footpaths and any other adjacent properties and section are given utilities or land uses in an event of a fifty year return period flood�. in Annex - I, (also refer design drawings for culvert locations and proposed drainage management plan) 1.2 Applicable -do- Designed rehabilitation and improvements must safely and adequately throughout the meet the expected level of services including estimated traffic loads and road capacities for the design lifespan.
