BSH/HGW/Clean Air Zone Traffic Signs

Surface Dressing will be carried out as part of a programme of work to include several sites. A variety of aggregates and binders will be required to meet the individual characteristics of each site. Micro Asphalt will also be ordered as part of a programme of works. Sites will be substantially located in an urban environment with constraints relating to traffic management within the City of Bristol boundary (and possibly that of other neighbouring authorities).

Work will usually be ordered as a programme of work with the majority of the work relating to footpaths, although some carriageway may be included. There may be a requirement to carry out preparation and or regulating work prior to the final installation. Sites will be substantially located in an urban environment with constraints relating to pedestrian and traffic management within the City of Bristol boundary (and possibly that of other neighbouring authorities).

Work may be ordered per individual site, or grouped within an area or may be part of a programme to reinstate markings following surfacing work. Preparation may be required including the setting out and or the removal of existing markings. Cold applied resins to be used unless otherwise specified for high friction surfacing. In some instance sites may require limited preparation or at existing sites where the removal of existing surfacing may be required. Sites will be substantially located in an urban environment with constraints relating to traffic management within the City of Bristol boundary (and that of other neighbouring authorities).

For the delivery of minor maintenance and new highway improvements using a schedule of rates as the basis including works of a similar nature off the highway.

For the delivery of larger scale, complicated traffic and highway schemes, and works off highway of a similar nature.

Various types of Minor Structural and Civils repairs with some small scale reconstruction works on all associated highway structures, including bridges and highway retaining walls. Undertaking of routine structural maintenance repairs and associated civils works to all types and construction of bridges (including swing bridges), culverts, subways and retaining walls. The work will involve routine programmed structural repairs and/or some civil reconstruction work to several small highway structure sites. There will also be an element of reactive emergency damage repair works due to RTC damage, although this Work will be expected to be undertaken during normal working hours. Sites will be substantially located in an urban environment with constraints relating to simple traffic management arrangements with limited working areas within the City of Bristol boundary (and that of other neighbouring authorities).

Large to medium scale Structural repairs and Civils reconstruction works on all associated highway structures, including bridges and highway retaining walls. Undertaking of routine structural maintenance and associated civils works to all types and construction on bridges (including swing bridges), culverts, subways and retaining walls. The work will involve routine programmed structural repairs and/or civil reconstruction work to several sites as well as larger scale works on discrete sites. There will also be an element of reactive emergency damage repair works due to RTC damage, although this will be expected to be undertaken during normal working hours. Sites will be substantially located in an urban environment with constraints relating to traffic management with limited working areas within the City of Bristol boundary (and that of other neighbouring authorities).

Maintenance programmed painting works to parapet railings and barriers to all highway structures. Structures to include bridges, retaining wall parapets, subway parapets, sign gantries and other ancillary highway structures. The programmed painting work to also include for the application of proprietary anti-graffiti coating systems to highway structures. The programmed work will be allocated into packages of several small sites or individually where a whole structure is to received and complete repainting. Sites will be substantially located in an urban environment with constraints relating to traffic management with limited working areas within the City of Bristol boundary (and possibly that of other neighbouring authorities).

Structural steelwork repairs/modifications and structural component replacement plus fabrication work using various forms of welding and mechanical connection methods. Undertaking of routine programmed structural steelwork repairs/modifications or replacement to bridge and retaining wall parapet railings including repairs or replacement to life expired or corroded structural components of all types of bridges and other highway structures, including bridge expansion joint plates, decking systems etc, including a degree of offsite fabrication in within a workshop. There will also be an element of reactive emergency damage repair works due to RTC damage, although this will be expected to be undertaken during normal working hours. Sites will be substantially located in an urban environment with constraints relating to traffic management with limited working areas within the City of Bristol boundary (and that of other neighbouring authorities).

Programmed structural geotechnical inspections, Routine programmed maintenance and associated stabilisation works to structural embankments and Cuttings as well as natural rock formations adjacent to the public highway. Work to involve routine cyclical de-vegetation and inspection of all formations and where necessary the undertaking of the required stabilisation work which may involve total or partial reconstruction, geotextiles and mesh stabilisation measures, anchoring stabilisation, or the installation of catch netting or other geotechnical control measures. Undertaking structural soil and site investigation including submitting reports. Sites will be substantially located in an urban and semi-rural environment with constraints relating to traffic management and other ecological and historical constraints with limited working areas within the City of Bristol boundary (and possibly that of other neighbouring authorities).

Provision of traffic management projects to facilitate road maintenance or event works.
