Funktionsentreprenad Brounderhåll : en pilotstudie i Uppsala länMattsson, Hans-Åke January 2006 (has links)
<p>Before 1992 the Swedish Road Administration (SRA) carried out all bridge maintenance and minor repair for all bridges in Sweden by themselves. The bridge maintenance crew in a county consisted typically of 3-6 workers and a bridge-engineer.</p><p>SRA and some contractors suggest that it could be a good idea for SRA to procure bridge maintenance in one or two counties for a long-time, e. g., seven to ten years. The bridge maintenance crew could be a model for this.</p><p>The aim of the research project is to present an updated model for procurement of bridge maintenance based on functional requirements. The base for this updated model will be the findings and conclusions that could be drawn from a real project – a case study. The research project shall continuously follow-up the performed maintenance and document how the contractor is planning and performing the work. The research will specially focus on measurable verifying methods for the performed maintenance. The results from the research project will be evaluated and compared with standard maintenance methods and the results will hopefully be used to update current regulations. The hope is also that the contractor will develop new and effective maintenance methods with the larger freedom a functional contract enables.

SRA and some contractors suggest that it could be a good idea for SRA to procure bridge maintenance in one or two counties for a long-time, e. g., seven to ten years. The bridge maintenance crew could be a model for this. The aim of the research project is to present an updated model for procurement of bridge maintenance based on functional requirements. The base for this updated model will be the findings and conclusions that could be drawn from a real project – a case study. The research project shall continuously follow-up the performed maintenance and document how the contractor is planning and performing the work.

The hope is also that the contractor will develop new and effective maintenance methods with the larger freedom a functional contract enables. At the end the final goal is to reduce the cost for the society for bridge maintenance in the future. The basic idea behind performance contract is that the client makes measurable functional demands with regard to the finished product, instead of presenting technical solutions. As an example the client could demand a certain friction and smoothness for the road surface. These functional demands should be formulated so that they have a direct relevance for the safety and flow of traffic. It is important that these functional requirements are divided into a target level and an absolutely lowest possible level (acute level). A contractor should maintain the target level both as an average functional level during the contract period and when the contract is completed. For the acute level there should be stipulated a maximum allowable time before corrective action needs to be taken. The methods that have been used in the research project are interviews, meetings, literature studies, reports, follow-up, statistics, participating in seminars, the authors own inspections, annual reports and so on. Since the author didn’t find anything published about bridge management on performance contract, to the author’s best knowledge, the literature studies have been concentrated on nearby topics, e. g., highways on performance contract and bridge maintenance in general et cetera. The research project has so far consisted mostly of a pilot study. From the beginning the idea behind the project was: • To procure bridge maintenance for the small and mid-sized bridges, • in one or two counties, • for a longer time, e. g., seven to ten years. • The value of a maintenance contract could be in the range of about 100 MSEK for the whole time. Since this is the first project of its kind in Sweden the owner (SRA) did not dare to let this pilot project be too voluminous. What will be tested and followed by this research project is to use contracting for maintenance based on functional requirements for all 400 bridges in Uppsala County in Sweden and for a period of three years and with an option for three more years. Uppsala County is situated some 20 km to 200 km north of Stockholm. To summarise the actual contract: • A contractor should perform bridge maintenance for all 400 bridges in Uppsala County. • The contract was three years (1 Sept. 2004 – 31 Aug. 2007) with an option for three more years (1 Sept. 2007 – 31 Aug. 2010). • The bridges were deemed to be in satisfactory condition if the contractor verified that they met the functional requirements in SRA’s regulations once a year. • Repair of 25 bridges during the contract’s first three years. • If the option for three more years will be used, then there will be some additional bridge repairs. • The contractor was expected to contribute in the research project. There were six contractors that requested the tender documents, but only three of them submitted an offer to SRA, see table below. Contractor Submitted offer Vägverket Produktion 20 387 943 SEK DAB-Domiflex AB 23 728 040 SEK NCC Construction 28 620 000 SEK (Advance 2 000 000 SEK) All of the three contractors deemed to have met the standards of a contractor set by SRA. Vägverket Produktion (VP) was the lowest bidder and therefore it was contracted by SRA for this project. Interviews were carried out with all six contractors that had requested tender documents. All of them thought that a multiyear bridge maintenance contract was an interesting idea. Large companies tend to want large contracts and small companies tend to settle for smaller contracts. All of the contractors thought that it was easy to calculate the 25 bridge repairs compared to bridge maintenance on functional demands. According to the contract VP should repair 25 bridges during a three year period. VP divided these repairs in three equal parts: nine bridges 2005, eight bridges 2006 and eight bridges 2007. The functional requirements for the bridges should be verified once a year according to the contract. Both representatives for SRA and VP carried out bridge inspections during the first year and it was noted that the representatives had a different view on some of the discovered defects on the bridges. The representatives had a different view mainly on the bridges’ structural members’ slope and embankment end, edge beam and surfacing. It is important to specify how to measure and interpret the results from inspections regarding defects in functional requirements.

Acute defects needs to be more precisely defined but could be surfacing against bridge, settling in slope and embankment end and flushing. These defects should be rectified as soon as possible. Non-acute defects could be rectified when there is enough work for the contractor to carry out but not later then October 31st every year. The research project will continue to follow-up and evaluate the first three years of the pilot study. The research project will also follow-up and evaluate if the option for extending the contract three more years will be used. According to the contract, if the option will be used, there need to be a meeting between the client and the contractor not later than 31 Aug. 2006 and a settlement need to be reached not later than 30 Sep. 2006. It is of interest to study the possibility to use, in future tender documents, the indicator Lack of Capital Value and/or the average permissible level of defects in functional requirements for the bridge stock. Further research should also be focused on how defects on different members of the bridge evolve and the cost associated to rectify them. It is of interest to know how many defects that are evolved during a normal year for the 400 bridges in the study. If one knew the number of defects one can estimate the costs to rectify these. The estimated cost can then be included as information for the potential contractor in future tender documents. So far SRA’s representatives are satisfied with the project and with the good relationship that evolved between SRA and the contractor. SRA is also satisfied with the increased focus on the bridge functional requirements. If this project will continue to show good results then SRA will consider procure bridge maintenance on similar contracts for more counties. / QC 20101119

Funktionsentreprenad med helhetsåtagande : – en studie av Norrortsleden / Performance-based constructionand maintenance contracts : - A study of NorrortsledenBjerneling, Linda, Åberg, Mikael January 2011 (has links)
Detta examensarbete är en utvärdering av arbetssätten i byggprojektet Norrortsleden och genomfördes på Trafikverket i Solna under hösten 2010 och början av 2011. Norrortsleden är en tvärförbindelse mellan E4 och E18 norr om Stockholm. Byggprojektet är två-delat där ena halvan genomfördes i en traditionell entreprenadform och den andra i en så kallad funktionsentreprenad med helhetsåtagande. Denna rapport fokuserar på den senare av dessa två. Examensarbetet ämnar finna, genom att använda Norrortsleden som exempel, vilka för- och nackdelar som funktionsentreprenad med helhetsåtagande för med sig. Detta görs utifrån tre olika aspekter: organisatoriskt, ekonomiskt och kvalitetsmässigt. För att åstadkomma detta har intervjuer med beställarorganisationen (Trafikverket) och entreprenören (NCC), ekonomiskkalkyl och en upplevelseenkät genomförts. Dessa har visat på ett antal positiva effekter med entreprenadformen men även på en del förbättringsområden. Entreprenadtypen har visat på förbättrat samarbete mellan beställare och entreprenör samt på stimulerande arbetssätt utan att kvaliteten blir lidande. Dock har det även visat sig att förvånansvärt få tekniska innovationer uppkommit och att entreprenadtypen kan ha en negativ inverkan på konkurrenssituationen i den svenska byggbranschen. Förutom detta, identifierades vilken typ av projekt som är lämpat för denna entreprenadtyp / This master thesis is an evaluation of the working methods used in the construction project of Norrortsleden. This thesis was conducted at the Swedish Transport Administration during the fall of 2010 and the beginning of 2011. Norrortsleden is a transverse route connecting E4 with E18 north of Stockholm. The construction project was divided into two halves in which one half was a traditional form of construction contract and the other a so-called performance-based construction and maintenance contract. This thesis focuses on the latter half and intends to find, by using Norrortsleden as a case, what the advantages and disadvantages this particular contract type entails. This is done from three different aspects: organizational, financial and quality. To achieve this, interviews at the Swedish Transport Administration and at the contractor (NCC), economic analysis and a questionnaire were conducted. These have highlighted the positive effects as well as some areas of improvement of this contract type. One of the positive effects is the improved cooperation between the STA and the contractor without compromising the quality of the end-product. However, it has also been proven to be surprisingly few technological innovations arising from this project and the risk of negative competitive effects has also been identified. Apart from this, the thesis has identified which types of projects are suitable for this contract type.
