Construction work for highways

Tender description

Bristol City Council intends to consolidate several highways work streams into 1 new framework and 2 term tender contracts all of them are to be launched and fully operational on 1.4.2017. Framework to include: (Surfacing) — Lot 1 Machine Laid Surfacing, Lot 2 Surface Dressing and Micro Asphalts, Lot 3 High Friction Surfacing and Coloured Surfaces, Lot 4 Slurry Seal and Preventative Treatments, Lot 5 Road Markings, Lot 6 Highways and Associated Works up to 1 000 000 GBP, Lot 7 Highways and Associated Works over 1 000 000 GBP, Lot 8 Highways Drainage, Lot 9 Drainage Engineering, Lot 10 Minor Bridge Repairs and Walling Works, Lot 11 Painting Works to Highway Structures, Lot 12 Steel Fabrication to Highway Structures and Lot 13 Geotechnical and Ground Investigation. To include preparation work such as road planning and or the adjustment of ironwork. Surfacing and or reconstruction work to be carried out using a variety of bituminous materials. The work may range from an individual site to a programme of work comprising of several sites which will be located substantially in an urban environment with constraints relating to traffic management within the City of Bristol boundary (and possibly that of other neighbouring authorities). 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). The work may be at new sites requiring limited preparation or at existing sites where the removal of existing surfacing may be required. The work may be ordered by individual site or as part of a larger programme of works. Cold applied resins to be used unless otherwise specified. 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. 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). A range of works orders from small maintenance jobs ranging between 10 000 GBP and 20 000 GBP to traffic and highway schemes where the works is not of a complicated nature up to 1 000 000 GBP within the City of Bristol boundary (and possibly that of other neighbouring authorities). Most of the works shall be in order of less than 250 000 GBP. The value of the works offered under this Lot is usually dependant on the success of major scheme bids to central government grant funding and the work usually consist of larger scale, complicated traffic and highway schemes within the City of Bristol boundary (and possibly that of other neighbouring authorities). To include routine highway gully cleansing, jetting and logging of works on an electronic hand-held device and to also include highway subways and footbridges. The provider will be required to disposal of waste at an approved location. The provider will be expected to undertake routine inspection and servicing of mechanical and electrical pumping stations and control equipment. To carry out surveys, locate blockages and establish the condition of drainage systems including submitting detailed reports to client. To carry out routine cleansing of trash screens and water courses. To carry out emergency cleansing of gullies or trash screens and remove flooding from the highway in and out of hours providing emergency call out 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). Drainage engineering work to repair, upgrade or the installation of new highway, watercourse and sustainable drainage infrastructure. Work will be varied and ranging from the replacement of a gully grating and frame or repairs to a head wall to the installation of a complete drainage system involving deep excavation and confined spaces. This work will require fully trained and experienced confined spaces operatives to enter excavations and drainage infrastructure. 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). Structural repair and Civils reconstruction works to associated highway structures. 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 small 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 off-site 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).
