Design, build, finance and operate (DBFO) started life as a precursor and transition to motorway tolling, designed to create an operating industry which took a long-term commercial view and which might manage tolled motorways in the future. With this in mind, the Conservative Government announced in November 1992 that private-sector companies might be invited to bid for DBFO projects, with remuneration from the government according to usage.
The DBFO concept was included for consultation in 'Paying for Better Motorways: Issues for Discussion' (May 1993). A preliminary note on the principles applying to DBFO was published in April 1994. Welcomed by the City and industry, financial advisers Hambros/Pricewaterhouse then carried out a more intensive consultation on risks.
As a result of this consultation exercise, the DBFO form of contract was developed. In summary, the private sector, over the 30-year life of the contract, assumes responsibility for the operation and maintenance of a length of existing road (where appropriate) and the detailed design and construction of specified improvement schemes and their subsequent operation and maintenance. These responsibilities lead the private sector to focus on delivering whole-life cost efficiencies. DBFO has developed into a method of procurement worth pursuing in its own right as an alternative to other forms of procurement using conventional funding arrangements.
Contracts for the first eight DBFO projects were all awarded in 1996 (sometimes referred to as tranches 1 and 1A). These involve the private sector in managing about 600km or 5 per cent of the existing Highways Agency network and delivering 11 road improvement schemes with an estimated capital value in excess of £550m. Ten of the 11 schemes were completed and opened to traffic by Spring 1999, with the remaining scheme, the A30 Honiton to Exeter Improvement, opened in the Spring of 2000.
Reimbursement on these contracts is primarily by means of shadow tolls paid according to usage of the project road, plus bonus elements for safety enhancements and charges for lane closures and penalty points for not achieving set operating standards.
The first four DBFO projects were the subject of a National Audit Office (NAO) report published on 28 January 1998, and a subsequent Public Accounts Committee hearing on 23 February. The conclusion of the latter was that the Highways Agency (HA) had made significant value-for-money (VFM) savings in the order of £100 million. A separate analysis of the first eight projects shows that they delivered VFM savings averaging 15 per cent.
The VFM of DBFO projects is established by placing each risk associated with the project with the party best able to manage that risk. Principal risks transferred to the private sector in the first eight DBFO projects included construction cost (including unforeseen ground conditions), opening date, operation and maintenance over 30 years, and traffic. Risks retained by the Department for Transport (DfT) included completion of the statutory procedures, land assembly, additional works required by the Secretary of State and events such as extreme weather conditions.
Three DBFO projects were out to tender when the Accelerated Review was announced soon after the General Election in 1997. These were:
These projects were subsequently cancelled. A number of other projects (A40 West London Approach & A36 Wessex Link) have also been considered for DBFO status but have been rejected. Information for all these projects is presented in 2c - Tranche 2 project fact sheets (Historic summary of DBFO projects).
Approved as part of the accelerated review of the trunk road programme conducted in summer 1997, the A13 DBFO provides a vital link in the transport infrastructure to assist regeneration in East London, improving east-west access to Docklands, the Lower Lea Valley and other parts of east London.
Following a pre-qualification exercise, four bidders were selected and tenders invited in August 1998. Tenders were returned in March 1999 and bidders shortlisted in August 1999. A provisional preferred bidder was selected in December 1999. The successful tender was awarded to Road Management services [RMS (A13) plc]. The contract signature was made in April 2000 and work commenced on 11 July 2000. At contract award the project was transferred to Transport for London (TfL), who are now responsible for this DBFO contract.
The A13 Thames Gateway DBFO project is the first example of a DBFO reflecting the government's integrated approach to transport. This is achieved by a new payment mechanism that moves away from the all-vehicle shadow-toll payment mechanism used on previous DBFO contracts, replacing it with a combination of:
This mechanism was the starting point for the development of payment mechanisms for two new DBFOs announced by Lord Whitty in December 1998 (see below).
The A1 Darrington to Dishforth DBFO project contains two upgrading and widening schemes, with a capital value of about £245 million. Construction has been completed on this project.
The A249 DBFO project contains three improvement schemes with a capital value of about £100 million. The contract was signed in February 2004.
The M25 DBFO project comprises the existing Area 5 network and Dartford Crossings - which together form the Project Road. Once let, a DBFO Company will assume responsibility for the operation and maintenance of the Project Road and a programme of capital works including the widening of up to approximately 102km of the existing M25, generally to dual 4 lane standard. The project is currently at the preferred bidder stage.
DBFO is not just a procurement option used in England. The Scottish Office awarded the A74(M)/M74 DBFO in April 1997 and the Welsh Office the A55 in December 1998. Both contracts are expected to deliver VFM savings, although in the case of the A74(M)/M74 DBFO, a National Audit Office (NAO) report concluded that the net benefits may be less than the £17 million calculated by the Scottish Office. The price, however, can be expected to remain VFM.
The project road comprises sections of the trunk road network in the Counties of Leicestershire, Northamptonshire and Bedfordshire, and to a lesser extent Buckinghamshire and Oxfordshire. Centred on the A6 and A43 trunk routes where they intersect at Kettering, it also includes sections of the A421 and A428.

The section of the strategic north-south A6 trunk road included in this project extends from the southern outskirts of Leicester to the north side of Luton. Whilst principally rural in character, this section of the A6 passes through a number of towns and villages.
The A43 trunk route forms an important north-south connection between the A1 to the south-west of Stamford and Junction 10 on the M40 to the north of Oxford. The route is generally rural in character, with discontinuities at the two major urban areas, Kettering and Northampton.
The A428 is an east-west route linking Coventry in the West Midlands to Cambridge and the east ports beyond via the A14. The A421 is a rural primary route, which currently extends from Bicester to the A6 south of Bedford. The Bedford Southern Bypass, which has now been constructed, will provide a link between the existing A421 to the south of Bedford and the A428 to the east.
The A428 Norse Road Link scheme was withdrawn following the roads review of July 1998 and the remaining schemes (A43 &A6 trunk routes) were conventionally procured under the TPI.

The Cumbria to Bradford project road runs from the A590/A592 junction at Newby Bridge via the A590, A65, A629 and A650 to the eastern terminal point of the proposed Bingley Relief Road. In addition to its strategic function as a trans Pennine route, the project road serves as a connecting route between intermediate centres of population. It also acts as a recreational route for tourism interests associated with the Lake District and Yorkshire Dales National Parks and Bowland Area of Outstanding Natural Beauty. This scheme was part of the Government's accelerated roads review and was subsequently suspended. The conclusion of the review was such that the DBFO tender period for this scheme was terminated.
The component schemes will be undertaken as follows:

The project road comprises sections of three trunk road routes, the A21 London to Hastings trunk road, the A259/A27 South Coast trunk road and the A26 trunk road between the A27 and the port of Newhaven. The A21 trunk road runs southwards from the A25 at Sevenoakes to the outskirts of Hastings. The A259/A27 trunk road from Hastings to Brighton is part of the Folkestone to Honiton South Coast Trunk Road. It is the only strategic east-west route across England south of the M20, M25 and M4 corridor and it links the major towns of Folkestone, Hastings, Eastbourne, Lewes, Brighton, Worthing, Portsmouth, Southampton and Bournemouth. The A26 trunk road provides access to the port of Newhaven from the A27 at Beddingham. This scheme was part of the Government's accelerated roads review and was subsequently suspended. The conclusion of the review was such that the DBFO tender period for this scheme was terminated.

The A40 is an important strategic radial route running in a generally east/west direction from inside the M25 to London's West End. At its western end it connects with the M40 motorway, Junction 1 while at its eastern end it connects with central London via the A501 and M41. The project road is one of the main arterial routes into central London. Starting in Buckinghamshire it passes through the Boroughs of Hillingdon, Ealing, Hammersmith and Fulham, the Royal Boroughs of Kensington & Chelsea and the City of Westminster. It is extensively used by commuters, tourists and commercial traffic from and to the Midlands.
The A40 West London Approach DBFO project, together with its two constituent schemes was cancelled in July 1997 as it was considered likely that this improvement scheme would encourage car commuting.

The Wessex Link DBFO Project was also cancelled in July 1997. The result of the Roads Review in respect of the relevant schemes is as follows:
In addition, the core requirements for the A13 contract have been amended to include provision of monitoring equipment to improve accident response times and variable message signs to inform road users of congestion, delays and public transport alternatives.

The following facts were correct as of the date of award for this project:
The A13 trunk road is a strategic East London/Thameside radial route. At its western end it connects with the City of London while its eastern end includes the new A13 Bypass to Wennington. The route is of major importance to industry located along the A13 and provides commercial vehicle links from East London and Docklands to the East Coast. These schemes are key to improving east-west access to Docklands, the Lower Lea Valley and other parts of East London, north-south local access and to supporting regeneration in a major part of the Thames Gateway. The Project will allow full use of the East India Dock Tunnel. The A13 passes through the London Boroughs of Tower Hamlets, Newham, Barking and Dagenham and Havering. The schemes included in this project are:

Sir John Bourn, head of the National Audit Office, reported to Parliament today that the Scottish Office had managed an effective competition for the £214 million contract to complete the upgrading of the *A74(M)/M74 in Scotland to three-lane motorway and to operate the road until 2027. The private sector partnership with Autolink Concessionaires (M6) plc is expected to bring benefits which offset the higher cost of financing the project privately.
These benefits include construction of the road in around 22 months, compared with an estimated 36 months for a conventionally financed project. Early delivery of the road will increase the cost of the contract for the Scottish Office, but these extra costs are expected to be matched by the additional benefits to road users resulting from advanced completion.
The National Audit Office found that:

Notes for Editors
*In April 1997, the Scottish Office signed a contract with Autolink Concessionaires (M6) plc to upgrade the existing 28 kilometre section of the A74 between Paddy's Rickle Bridge and Cleuchbrae in Scotland to motorway standard, and to operate and maintain the 92 kilometre length of the M74 between Millbank and the border. In return, the Scottish Office will make payments to Autolink based on the volume of traffic using the road, subject to a maximum in each year - so called "shadow tolls".

UK Highways A55 Ltd has been awarded the contract to design, build, finance and operate (DBFO) the A55 extension across Anglesey, Welsh Office Transport Minister Peter Hain announced today.
It is the first roads project solely within Wales to be procured by Private Finance. Work is expected to take about three years and be completed in 2001.
Mr Hain said:
"The importance of this project is reflected in the fact that it was the only scheme exempted from the strategic review of the Welsh trunk road programme,
"The new road will bring a better quality of life to people living and working along the existing A5 on Anglesey and will increase economic prosperity in North West Wales. In particular it will aid the economic regeneration of the island as a whole and Holyhead in particular. It will improve both road safety across Anglesey and communications with the rest of Wales and beyond into Europe."
The project will be:
The additional lengths of existing trunk road have been included in the DBFO project to improve traffic management at the approaches to Britannia and Menai Bridges and allow greater operational flexibility during closures of either bridge for maintenance or in extreme weather.
Notes
UK Highways A55 Ltd is a consortium made up of Laing, Tarmac and Hyder.
The concession period will be for 30 years during which time the contractor will design the new scheme, fund its construction, manage and maintain the network of the roads within the project. In return the Government will pay shadow tolls on a formula based upon the number of vehicles using the road and lane availability. After this time responsibility for the operation and maintenance will revert to the Government.
The concession includes the design and construction of around £100m of new roads and the operation and maintenance of the A5/A55 trunk road between Llandegai and Holyhead.

In a recent speech (spring 2004), Steve Rowsell, the Highways Agency director for procurement, outlined future developments in the delivery of privately funded road schemes in England. Highways Agency's Procurement Strategy stated that the spending plans included in the 10 Year Plan allow for 25% of the additional capital investment in the trunk road and motorway network coming from private finance.

A consultation document, "Improving DBFOs" , was published in 2003. The aims were to:
The document provided an opportunity for the industry to help shape future DBFO procurement and operations. Over 50 responses were received (figure 4.1 shows a breakdown of the types of respondents). Following the consultation, a working group has been established to review the responses and workshops/ dialogues which are taking place with selected respondents.
The three principle messages received from the respondents were that the Agency should work towards:
Is paying over 30 years similar to a credit card transaction and therefore more expensive?
No. We are paying for a high quality road service which over 30 years is expected to deliver better value for money than conventional forms of procurement.
But can payment over 30 years represent value for money (VFM)?
Yes. The NAO concluded in its report on the first 4 DBFOs that the Agency can be expected to deliver VFM savings of about £100m. First 8 projects delivered average savings of 15 per cent.
A major principle of DBFO contracts is that the risk is placed with the party who is best placed to manage and deal with it as this provides best value for money. The private sector is reasonably expected to be able to assume and manage a wide range of the risks associated with designing, building and operating a road better than the public sector under traditional methods of procurement. The placing of risk appropriately in this way is likely to provide better value for money than placing risks with those not well able to manage them. The fact that the DBFO procurement process for each scheme has taken care to identify and allocate risks through a highly competitive process gives assurance that the contract terms were the best obtainable from the market for deals of this type at the time.
What risks are transferred?
DBFO contracts transfer a range of risks, including outturn cost of construction, future maintenance and level of traffic. Efficient risk management underlies VFM.
The allocation of risk and reward between the contracting parties should be clearly defined and private sector returns should be genuinely subject to risk. The DBFO Co will be expected to assume the majority of the risks associated with the design, construction, maintenance, operation and financing of the Project. These risks will include the risks of construction and maintenance to time and to budget and making whole life cost judgements.
What if the DBFO company performs poorly?
Remedies are available in the contract to ensure that the DBFO company's performance improves.
One of the main operational issues for the Agency is how to ensure that the DBFO Co complies with the terms of the DBFO contract, post-award. Under the terms of the DBFO contract the Agency appoints representatives to monitor the construction, operation and maintenance carried out by the DBFO Co to ensure that it complies with its contractual obligations.
The DBFO contracts contain a penalty point mechanism, which attributes points, for failure to perform under the contract. The allocation of penalty points has specific threshold triggers and increased monitoring requirements. Once a specified number of penalty points has been exceeded, the Agency has the right to terminate the contract. The Agency also has a number of other remedies arising from non-performance, including the right to remedy any default and invoice the DBFO Co for its costs.
Who regulates the DBFO Co under the Contract?
DBFO roads remain part of trunk road and motorway network and hence the Secretary of State remains the Highway Authority and will ensure that standards are met. (Also, see above)
Will DBFOs inhibit change?
No. Contracts make provision for technical or commercial change. The DBFO contracts represent the Agency's current approach on how to meet the demands on each project road. Over each 30 year contract period however, circumstances will change and the Agency therefore has reserved the right to change the service specification during the contract period, because it retains responsibility for strategic management of the whole network. To do this, a change procedure is required within each contract. Bidders however will not enter into an agreement where the Agency can change the specification at extra, unanticipated cost to them. The solution is that the DBFO contract contains scope for possible changes required by the Agency, and for a method of adjusting the payment mechanism to allow for changes in costs or effects on traffic flow.
What are the user benefits?
Bidders judge the best long-term value in their construction proposals to minimise the need for repairs. Less long-term maintenance means less disruption to traffic - good news for road users.
Why is the Government allowing profit-led private companies, with no regard for public opinion, to take over road building?
No. Traditional procurement uses private contractors. DBFO contracts extends the principle of private sector management skills but does not bring in private sector ownership.
How long between the ITT and the Contract award date?
Experience of the DBFO tendering process to date has shown that we can expect a contract to be awarded some 11 to 16 months after inviting tenders, subject to bidders submitting well-thought-out tenders that represent value for money.
What is the effect on statutory procedures?
The Secretary of State for the DfT remains the statutory highways authority throughout the period of the DBFO contract and the situation regarding statutory requirements including planning applications will remain unchanged. The Highways Agency's main role is to monitor the performance of the DBFO company, taking appropriate action to ensure that any expressed local concerns are addressed.
What will be the environmental impact of the contract?
The DfT, via the Highways Agency, does carefully and properly maintain trees and shrubs planted as part of new highways schemes. The work itself is normally carried out by agents. These include Forest Enterprise England (an agency of the Forestry Commission); local authorities; or private-sector consultants, as appropriate. On DBFO contracts it is a requirement that the successful contractor puts similar maintenance arrangements in place.
Which third parties will the DBFO Co's have to liaise with?
The DBFO company is required to liaise with the local highway authorities, emergency services and others as part of their obligations under the contract. In addition, the Secretary of State for the DfT remains the statutory highway authority. The Highways Agency's main role is to monitor the performance of the DBFO company, taking appropriate action as necessary, to ensure that any expressed local concerns are addressed.
In carrying out its responsibilities, a DBFO company is required to liaise with existing and adjoining local authorities and ensure that their operation and maintenance procedures are compatible with those which will continue to apply on roads adjoining the project road.
Do Shadow Toll Payments encourage DBFO Co's to generate increased levels of traffic?
We do not accept the argument that payments to operators related to use will act as an incentive to generate traffic. Operators will not be able to offer direct incentives to encourage additional journeys on the project road. The incentive is for the DBFO company to operate the road at maximum efficiency and safety with a minimum of time when lanes are out of use. This is in the interest of road users and the efficiency of the trunk road network.
Shadow tolls from the government, linked to usage of the road, provide an incentive for efficient management. Beyond this incentive, the DBFO company is not able to influence the growth of traffic using the road and sustainable development policies are not undermined.
The payment mechanism does not increase traffic volumes. DBFO companies have a very limited influence over road usage, and payments are capped for traffic volumes above a certain level. The incentive is for the DBFO company to manage and maintain the project road well enough so that it operates at maximum efficiency.
The NAO has criticised the Agency for using a Shadow Toll based payment mechanism. What has happened since the NAO report?
As acknowledged by the NAO, the Highways Agency was already developing a new mechanism before the reports were published. This new mechanism was used for the first time for the A13 Thames Gateway project in East London. A minimum of 70 per cent of income paid to the private sector will relate to their performance in keeping the road, footways and cycle ways available to users. The private sector will also receive some volume related payments for long vehicles (HGVs, buses and coaches), and the payment mechanism also includes payments related to the safety record of the project road.
Further payment mechanisms were devised for the A1 Darrington to Dishforth DBFO contract and the A249 DBFO contract in North Kent. These incorporate incentives for the private sector to deliver a service in tune with the government's objective of reducing congestion. Active Management Payment Mechanism.
The procurement process - how are projects awarded?
Prequalification - A contract notice is published by the Agency in the Official Journal of the European communities inviting requests from interested parties ("candidates") to prequalify with a view to later being invited to tender for a DBFO Contract in respect of the Project. The prequalification document provides additional information and describes the procedure ("prequalification") for selection of candidates with whom the Agency wishes to invite to tender and enter into negotiations. It should be read in conjunction with the Public Works Contract (Negotiated Procedure) Notice published in the Official Journal. The Agency will wish to be satisfied that each candidate selected to tender for the project has the appropriate qualities and resources available to it, to undertake the tasks required of the DBFO Co. Candidates are selected in accordance with the negotiated procedure and are required to supply standard corporate information.
Tender - in order to initiate the tendering process, the Agency sends to Tenderers a set of tender invitation documents (the "tender invitation documents"), including a draft of the DBFO contract (the "draft agreement"). The tender invitation documents set out the Agency's position regarding the definition of obligations and the allocation of risk. Tenderers are required to submit a tender on that basis (the "Standard Bid"). The Agency will also consider variant bids subject to compliance with the specified requirements (a "variant bid").
At tender stage a substantial amount of information is made available to the Tenderers, including any existing design information. For early DBFO Projects, this information was provided by way of dataroom document facilities, but more recently have been provided to Tenderers at the start of the tender period on CD-ROM. Tenderers are required to propose their own designs for the Project, and are encouraged to incorporate innovative ideas which deliver good value for money for the Agency. During the tender period, Tenderers are required to agree, in principle, with the Agency any significant departures from standard, outline proposals for structures and any proposals for new or alternative standards.
In addition to their technical proposals, Tenderers are required, in their Standard Bid, to stipulate the amount of DBFO Payments, which they propose on the basis of the obligations and allocation of risk as set out in cash flow projections, which include forecast cost, revenue data and financing proposals.
Tenderers are also encouraged to propose alternative obligations or allocations of risk as Variant Bids. They are required to state the effects on DBFO Payments of such Variant Bids, with the same level of detail defined as that of the Standard Bid.
Negotiation - The Agency negotiates with Tenderers to refine and finalise the definition of obligations, the allocation of risk and the attendant payments to be included in the DBFO Contract. At the conclusion of the negotiations the Agency selects the successful Tenderer (the "DBFO Co") on the basis of the most economically advantageous tender.
Award - DBFO Contracts are awarded under the negotiated procedure applicable to Public Works Contract Regulations 1991 (SI 1991/2680) ("the Regulations"), which implement the EC Works Directive (93/37/EEC). The basis for the award of a DBFO Contract will be the most economically advantageous bid against the criteria set out in the Tender Invitation Documents. Value for money, which is achieved by minimising cost while maintaining the required service levels and allocating risk to the party (Public or Private Sector) best able to manage it, is a key factor in the Agency's evaluation of Tenders.
Public sector comparator - To ensure that each potential DBFO project satisfies the twin tasks of value for money and optional risk transfer, the Agency prepares a Public Sector Comparator (PSC) before deciding whether to invite bids for projects under DBFO conditions.
For each DBFO project, the Agency needs to decide whether the proposed contract offers value for money compared with conventional procurement. A Public Sector Comparator is calculated by costing what the public sector would have had to pay to procure the construction of the relevant schemes and the operation and maintenance of the project road over 30 years by traditional means. The calculation includes an assessment of the risk resting with the Agency under conventional procurement.
The Agency prepares an assessment of Net Present Value (NPV) of the PSC, and compares this with the NPV of the projected payment under the DBFO contract (although the Agency has also to take into account other value for money considerations, which may not be quantifiable but may be significant, for example, environmental considerations or other policy objectives). Taking into account all these considerations, the Agency's Accounting Officer (the Agency's Chief Executive, who is answerable to Parliament for the Agency's commitments) needs to be satisfied that value for money is best achieved by means of the DBFO contract.

The result of the comparison between the public sector comparator and the winning DBFO bid were calculated using an 8 per cent real discount rate, which was the Treasury's recommended rate for assessing road projects when these contracts were awarded in 1996. The Highways Agency undertook sensitivity tests to assess the impact of different discount rates. The effect of using a 6 per cent real discount rate (which then became the recommended rate for assessing road projects), reduces the total saving to about £229 million (14.4 per cent). The advice in Her Majesty's Treasury (HMT) book entitled "Appraisal and Evaluation in Central Government" (The Green Book) has now been revised and the discount rate reduced to 3.5%.
Note 1: A Public Sector Comparator (PSC) is a benchmark against which value for money, in undertaking projects under the PFI, are assessed. The PSCs used by, for example the Highways Agency, are cost estimates for a notional project that has the same scope, outputs and timing as the PFI project. Costs are compared over the whole life of the contract and therefore include the operational/maintenance costs as well as the construction and financing costs. The PSC differs from the PFI project in that it is assumed to be undertaken under a traditional procurement route, resulting in greater risk being retained by the public sector, the costs of which are estimated in the PSC.
Under DBFO contracts, the private sector assumes substantial risks, including those relating to designing, building and operating the roads. Generally, the private sector is expected to be able to manage these risks better than the public sector, thereby providing better value for money.
A highly competitive procurement process helps ensure that the agreed terms are the best on the market at the time.
