                          Contract state that the employer will obtain this licence, but that the con-
                          tractor must comply with all other requirements of the Act and any conditions
                          attached to the licence (Clause 27). The contractor has to give notices as
                          required by the  Act and the Street Works (Registers, Notices, Directions
                          and Designations) Order 1992. Notice to start work must be given at least
                          7 working days in advance, and the work must be started within 7 days of the
                          notified starting date. The Street Works (Qualifications of Supervisors and
                          Operative) Regulations 1992 require a qualified supervisor and at least one
                          qualified operative to be full time on site. Road reinstatement requirements
                          are set out in the Street Works (Reinstatement) Regulations 1992 and a Code
                          of Practice issued by the Secretary of State.
                            A highway authority can direct the timing of works, require safety meas-
                          ures and stipulate avoidance of unnecessary delay or obstruction. A standard
                          charge for inspections can be made and the authority can also charge for the
                          occupation of a highway where works are unreasonably prolonged, and for
                          the cost of temporary traffic regulation.
                            The highway authority is required to keep a register of street works; this
                          can be of use to the contractor but, in the nature of things, it may not show
                          every service that lies underground nor provide exact information as to its
                          position. A highway (termed a ‘street’ in the 1991 Act) normally means all the
                          land between the boundaries of private properties fronting on a public road,
                          that is, including the road verges.
                            The diversion of existing services often requires joint action by the agent and
                          resident engineer. If need be, the resident engineer should arrange for meetings
                          with the district engineers of the authorities concerned, for example, county or
                          district roads department, gas, water, sewerage, electricity, telephone and TV
                          cable authorities. The resident engineer must see that the reasonable require-
                          ments of the various authorities are complied with by the contractor; on the
                          other hand he should help to resist any unreasonable requests being put upon
                          the contractor. Most authorities prefer to divert their own services; many will
                          not permit a contractor to undertake diversion of their equipment. Similarly
                          with respect to final road reinstatement, the road authority has power to do this
                          and may prefer to do so. A common requirement of a road authority is that a
                          trench for a pipeline, sewer, etc. laid along a road must be at least 1m away
                          from the road edge (i.e. fully in the road or fully in the verge), except where it
                          has to cross below a road edge.



                          12.15 Site drainage


                          Difficulty often occurs in draining a site where large scale earthmoving is tak-
                          ing place. The excavations disturb the natural drainage of the land and large
                          quantities of mud may be discharged to local watercourses during wet weather.
                          Complaints then arise from riparian owners and water abstractors down-
                          stream. If this possibility should occur the resident engineer should advise the
