FOR BRIDGE CONSTRUCTION

I.      Criterias of AMDAL, UKL-UKL and SOP

Sub projects which require environmental Standard Operating Procedure (Environmental
SOP) are those which excluded from the AMDAL and UKL-UPL’s criterias (table below).

II.     Objective

The objective of this environmental SOP is give environmental safeguard consideration
(physic, biology, social, health) on the planning, construction and maintenance stages.

III. Bridge Subproject Description

Basically, this environmental SOP describe environmental mitigation for minimize negative
impacts of road subprojects activities. The activities of bridge subprojects group into pre-
construction, construction, as follows:

1. Pre-construction Stages
      a. Socialization
          The socialization can be carried out by install announcement billboard, on the places
          which is easy read by public, for examples as figure below:

                    It will be rehabilitate/reconstruc
                                 bridge .....
                              length ......... m

        The socialization is in order people know about activities, and then social impacts can
        be early anticipated.
     b. Filed Survey & Measurement
        The field survey and measurement carried out after socialization.
2.    Construction Stage
     a. Worker Recruitment
        The construction worker recruitment must give priority to the local communities, in
        order to prevent social jealous impact from local communities to workers from
     b. Material Mobilization
        Material mobilization (especially for soil) must use truck with canvas closer.
     c. Basecamp
        Base camp must be completed with toilet and trash can.
     d. Land Preparation
        If there are trees cutting in land preparation, it is required do replanting.
     e. Soil Works (cut and fill)
        Soil works (especially cutting) potentially disturb to existing underground facilities.
        Contractors must looking for information about those before do soil works..
     f. Bridge Work
        Bridge works potentially have impact on stability of riverside. Contractor must keep
        riverside stability.

   g. Asphalt Works
      During asphalt works, it is may occur traffic jam on surrounding of the existing road.
      Contractor must be concerned on this and do traffic management in order to minimize
      or prevent traffic jam impacts.

IV. Environmental Standard Operating Procedure (Environmental SOP) For Bridge

The environmental standard operating procedure (environmental SOP) is present in tabel
below. The table contain:
1. Environmental Safeguard, environmental component which must be kept.
2. Environmental Standard Operating Procedure (SOP), mitigation measurement that
   must be carried out in order to keep environmental safeguard.
3. Threshold, threshold which must be reached from mitigation measurement.

                         - If there are underground facilities in the subproject
                            location, the contractors must coordinate with the
                            utilities owner, before soil works implementation.
                            The contractor is responsible to keep these utilities.
                         - If the utilities broken during soil works, the
                            contractor must repair according to the request
                            from its owner.
