We maintain over56,000 street lights


Project overview

IntroductionThis information pack has been issued to give you as members and local councillors, a greater awareness of the works which will be carried out in your area. We hope that by reading this pack you will gain a better understanding of the work processes that will be undertaken, what you need to do, and who to contact for assistance if required.It is essential to Balfour Beatty Living Places (BBLP) and Cambridgeshire County Council (CCC) that Parish/Town Councils and interested residents fully understand the changes that are being proposed in their areas. It is also important to understand there will be minor disruption whilst work is undertaken and most importantly that the necessary works are completed in order to achieve the project objectives and associated benefits to the County.

Each stage of the project has been laid out in this document to help you understand exactly what will be happening and why. If you feel that you require any additional information, guidance or to arrange a meeting to run through the information in this pack please feel free to contact:

Keeley Russell from Balfour Beatty [email protected]

or Cambridgeshire County Council [email protected]

who will be happy to help you.

We hope that by working together we can help yourselves and therefore the residents in your area to understand the processes and the importance of the works that we will be completing over the coming years.

We look forward to improving the lighting in your area soon.


Project overview

The backgroundAs with many Authorities, Cambridgeshire County Council was faced with the problem of an aged and inefficient lighting stock. Many of the old street lighting columns in Cambridgeshire were nearing the end of their life, and would soon present a hazard both structurally and electrically if not replaced. Outdated materials such as concrete, cast iron, and aluminium are prevalent throughout the County.The orange light provided by the majority of the old street lights is inefficient, offers poor light control and will soon be obsolete. The inefficiency of the existing lights places a huge burden on Council budgets with the cost of energy also rising year after year.

Under the previous lighting agreement these inefficient lights were designed to run to extinction, meaning they were allowed to completely burn out before finally being replaced. This meant that old lights are frequently out throughout the County, resulting in a perception of poor lighting to residents and resulting in a very inefficient system of travelling throughout the County sporadically changing lights.

Cambridgeshire County Council acknowledged that intervention in the lighting asset was required but faced a huge financial challenger to carry out improvements on this scale. Around this time central government funding in the form of PFI (Private Finance Initiative) Credits became available and this was a key opportunity for the Authority. The CCC project team succeeded despite stiff competition from other Authorities to secure the credits and funding to address the challenges it faced.

In July 2011, the 25 year PFI contract commenced with Balfour Beatty appointed to work in partnership with CCC to undertake the replacement and maintenance works throughout the County. The first phase of the project is the replacement and upgrading of the failing columns and inefficient lighting which will be completed over a five year Core Investment Programme (CIP). This will result in a safer, innovative, efficient lighting stock with improved performance standards.

As part of the central government funding in the form of PFI Credits the County Council are required to make a reduction of 10% of the street lighting assets across the County. As traffic routes are being completely redesigned (and the savings from redesign are already factored into the contract) the columns for removal can only be taken from residential roads. This means that some residential roads may see several columns being removed and not replaced. However, we anticipate that by using a combination of more efficient lighting and good design there will be minimal impact in the area.


Project overview

What are the benefits?As an innovative, forward thinking County, the partnership has procured a solution that will drastically reduce the energy used and CO2 produced, and will leave the Council with a legacy of reduced running costs and a future proofed asset. The benefits to the Authority, residents and stakeholders are enormous and are listed below:

The improvements will reduce energy consumption by approximately 46%. This equates to approximately 8.5 million kWhrs a year! That’s enough to power 1,454 average UK homes for a whole year and at today ’s energy prices that will save in the region of £850,000, meaning that much needed funds can be released to other service areas.

Introducing more efficient white lights in residential areas which have a better colour rendering abilityMeaning that colours can be defined and facial recognition improved.

Conversion of every bollard in the County to solar powered or high reflective bollardsTherefore avoiding a need for a mains supply and reducing energy costs.

The Central Management System (CMS) will allow lighting and switching levels to be changed remotely. This will allow the asset to be adapted to reflect future changes in standards, address alterations to local infrastructure, rises in energy charges and revised carbon emission targets. The CMS will also bring a reduction in the need for night time scouting.

Improved performance and response times to faults and emergencies

A reduction in burning hours and dimming of lights when traffic flow and pedestrian footfall has reduced

Low wattage LED sign lights, and the de-illumination of signs where possible


TYPE OF COLUMN DESCRIPTION CHANGE

‘Deemed to Comply’ columns These are columns that have been identified as being structurally capable of lasting the full length of the contract

The column will remain but the lantern will be replaced with a new white light

‘Non-Deemed to Comply’ columns These are nearing or achieved life expiry and will be replaced during the Core Investment Programme

These will be replaced with new columns. The new columns are likely to be slightly taller than the previous ones in residential roads and will be fitted with a new white light

Parish/Town Council owned columns

Columns that are owned and maintained by the Parish or Town Council

There will be no change to these columns unless by special request charged to the Parish and Town Councils

Columns of special interest Some historic columns are of special interest and have particular requirements under the contract

This varies depending on the specifics of the contract

Project overview

The workIn order to realise the huge benefits, the area in which the work is being carried out will experience some disruption. This will be in the form of excavations, barriers on site, and the presence of personnel and associated plant/equipment.It must be remembered that we will be upgrading approximately 56,000 units over a five year period, therefore the works will be noticeable throughout the County. A detailed description of what’s involved and what to expect when the work is carried out is covered later in this document.

The equipment types which will be used throughout the PFI have been identified, agreed and set out within the contract. These will be standardised throughout the County to ensure uniformity and simplify maintenance.

The table below identifies the type of lighting existing in the County and the changes that will be made to the street lights.

A programme of work has been produced for the Core Investment Programme (CIP) with every division in the County covered. There are two categories for the road types, identified as either traffic routes or residential areas. The table below describes the approach for each of the types of road.

TYPE OF ROAD APPROACH

Traffic route Traffic routes will be completely redesigned to achieve a lighting class set out in the standards. ‘Deemed to Comply’ columns will remain where possible and absorbed into the new designs, however, most columns will be replaced. The location of many columns are also likely to change

Residential roads Columns in most residential roads will be replaced on a one-for-one basis (i.e. close to the existing column) but typically located at the back of the footpath. ‘Deemed to Comply’ columns will remain but ‘Non-Deemed to Comply’ will be replaced with new columns. As part of the PF I funding, 10% of columns will be removed and not replaced. These removals need to be primarily taken from residential roads. In certain residential roads the lighting will be redesigned to achieve a particular level in line with the standards


Project overview

Lighting levelsThe lighting levels for each street have been set out in the contract.Throughout the Core Investment Programme the current orange lanterns in residential areas will be replaced with a new white light. This is a brighter light, which spreads further, illuminating more of the highway.

These lights will dim by 40% from 10pm until 6am. This dimming process will not be implemented immediately and only after a street has been fully completed. On traffic routes lights will be replaced by a gold type light and will dim in two stages: 20% between 8pm midnight, and a further 20% until 6am.

Column removalsThe decisions on which columns are removed from a street are based on a policy approved by the County Council and utilise technical skills and knowledge to minimise the impact on the street as a whole.Considerable time is given by the designers when identifying removals and we are always sensitive to the impact these decisions may have. The consultation process should identify any significant issues with a particular removal so that it can be addressed and if possible alternative found prior to the commencement of the work.

When selecting columns for removal; where possible we try to keep the first in the road, the last in the road, columns near a junction, columns lighting school areas and avoid removing two columns in a row. This is a contentious issue and may be the cause of many queries throughout the process.

SupportWe know that communities often consider street lighting as a key feature of maintaining and enhancing levels of safety and wellbeing. We are always willing to provide assistance and support to ensure that the outcome is satisfactory.For general comments relating to street lighting faults, general enquiries or if you are concerned about the impact of these changes in your area, we can be contacted on 0800 7838 247 or by email: [email protected]. We will be happy to talk you through any details or queries and if required we can arrange for someone to meet with you.

In addition, representatives of Balfour Beatty would be pleased to attend any meetings at any stage to explain the future works.

As is the case with many new and innovative projects there will be significant changes which unfortunately will not please everybody. Rest assured however that the contract has been set up to implement Cambridgeshire County Council policy and Balfour Beatty supports this through all of our works and procedures.

Consultation and engagementAny comments received during the consultation period will be taken into account when formalising the ultimate solution.Whilst every effort is made to accommodate individual needs, final decisions are made based on the overall impact on a community, and the achievement of the best lighting solution possible.

It is essential that comments on removals and concerns on designs are reported as early as possible so that any issues can be addressed prior to the commencement of works. Expectations should be managed as it will not be possible to meet all individual and often conflicting wishes in all circumstances.

The following table describes the consultation process to be undertaken by the partnership prior to the commencement of work in an area with their appropriate timescales. Please note that the timescales stated are minimum values only.

Please note the response times for each action and the deadlines set, as these are extremely important. It is critical that any comments are made as soon as possible.

CambridgeshireStreet Lighting PFIDrawings

We maintain 2,300 illuminated bollards


Drawings

Understanding the informationYou will receive an email with the drawings of the proposed street light installations and removals in your area for your comment and consideration.If you have any direct comments please feel free to contact Balfour Beatty either by phone on 0800 7838 247 or via email at [email protected].

You can also choose to view the drawings online and submit your feedback electronically. To do this please follow the step by step guide laid out below which shows you how to access the necessary information to allow forto understand the street lighting designs in your area.

Step 1: Accessing the websiteGo to the specifically designed website www.lightingcambridgeshire.com

To access the new drawings for your area click on ‘New Lighting’ in the menu bar.

Step 2: Selecting the drawingsThis page shows the entire street list for scheduled works, separated by area, and the timescales for commencement. By clicking on the name of the street, a map will appear showing the location and type of street lights due to be installed, replaced or removed.

Step 3: Viewing the drawingsTo assist in viewing the map, click on the icon to zoom in or out as desired. It can also be re-orientated.

Some drawings will show a street in its entirety whereas others, due to the length of the road, are split. The splits are from left to right and separated by a ‘cut line’. These cut lines are imaginary lines used to split up the roads into sections so that more of a road can fit onto a drawing by stacking sections onto a single drawing. Generally a cut line will start at Cut Line A in the top left of a drawing and follow on through to the bottom right. A visual representation of this is shown on pages 16 and 17 in Figures 5, 6 & 7.


Drawings

Understanding the information (continued)Step 4: Understanding the drawingsAlthough the drawings may appear to be very complicated, they are produced in a uniform fashion to make them easy to understand. The descriptions and annotated diagrams below have been drawn up to assist in understanding these but if you do have any additional queries please contact Balfour Beatty and we will try to assist.

Each street light on the map has two sets of numbers. Numbers in the form of “CC7”, for example are old Cambridgeshire County Council numbers which will be written on the existing columns on all roads that have not yet been through the replacement programme. The new numbers, typically a letter followed by a number and then three more letters, i.e. “L1PEG” are numbers which will be affixed to all new and deemed-to-comply columns which have undergone the programme of works. This new numbering system gives each column in the County an individual ID which allows for much more accurate identification of columns.

Signs are also afforded numbers, denoted by the letter S followed by an individual number, of either 3 or 4 digits, i.e. S6543.

As can be seen from the annotated figures, there are various symbols of varying colours associated with these different numbers, each of which represents a different item.

� Those with a green circular symbol are ‘Deemed to Comply’ and so will remain as they are, apart from a lantern change to upgrade to the new lanterns.

� Those that are represented with a red cross hair are ‘Non-Deemed to Comply’ and are due to be replaced with a new column.

� Those that are represented with a red cross hair and thick red ring have been highlighted for removal and not to be replaced.

� Those with a blue circular symbol are new columns which will be installed as part of the programme of works.

� Triangular symbols in blue are new signs to be installed.

Step 5: Providing feedbackComments should be made by contacting Balfour Beatty either by phone on 0800 7838 247 or via email at [email protected].

� Triangular symbols in red represent old signs which are being removed.

� Triangular symbols in purple are non-illuminated signs to be replaced.

� The symbols with letters represent the various electrical works to take place. Different colours (black/orange) denote different cable types:

D – Disconnection of an old column/illuminated sign.

T – Transfer of electrical supply from an old column/ sign to a new one.

N – New Service to be installed for a new column/sign.

Explanation of cut linesCut lines are used to break-up long roads so that they fit onto the A3 drawings, these drawings are used on site and are a key tool. Originally the design model starts off as a single road, as the road exists in real space. The cut lines are then placed at even points, as displayed in Figure 5 below, splitting the road into segments. These segments can then be displayed on the A3 drawings, as displayed in Figures 6 & 7 on the next page, following on from each other in a linear fashion.

CambridgeshireStreet Lighting PFIStreet lighting upgrade process

We maintain 3,900 illuminated traffic signs



Pre-installationInitial planning

� Initially, an overall plan is created to give a high level outline of the order in which each area will be completed.

� A mix of column heights, install difficulty and complexity must be maintained throughout to ensure that an even workload is kept for a steady workflow throughout the installation period. Local factors such as events will also be considered when planning works.

� Clashes with other works and unforeseen circumstances on site mean that priorities can change and that the programme can alter.

Site survey and pre-design Information � An on-site survey is undertaken to visibly assess the

area to be lit and review the existing lighting equipment. In addition, the surveyor will carry out electrical feed inspections and check for hazards and obstacles (such as drives, trees, buildings and road layouts).

� Check for the presence of underground and overhead services.

� Liaise with local Tree Officers to identify conservation areas and trees with Tree Preservation Orders attached (TPOs).

� Ascertain whether the road has any listed buildings or is in a conservation area.

� Define whether the road is a traffic route and/or has any conflict areas (i.e. junctions, roundabouts etc.)

� Decide on specific design levels.

� Identify removals to achieve the 10% overall reduction



Pre-installationDesignThere will be two types of design used within Cambridgeshire:

One for one replacements:

� Primarily in residential areas.

� Majority of new columns will be placed within 3m of the old columns.

� Some columns will be permanently removed and not replaced.

Complete re-designs:

� Used on specified traffic routes, and certain residential streets.

� Road lighting will be completely redesigned to new lighting standards.

� New columns may be placed in completely different positions to the old columns which will be removed in most cases.

A lighting designer can face many challenges, and must balance many factors when lighting a road. From the outside, it may appear that a column position has not been carefully considered, however, this would never be the case. For example, the siting of a column adjacent to a tree is always avoided where possible, but other factors may mean that this is a necessity. In many cases columns are moved out of trees as part of the redesign.

When completing their designs, our specialist design team must consider:

� The safety of our workforce and the avoidance of installing lighting columns adjacent to overhead lines. Installations must consider guidance in accordance with G39 & HSE GS6 guidance.

� Underground services – an electrical service has the potential to kill our workforce. Where possible high voltage cable must be avoided, therefore this could dictate which side of the road the columns are located. Conversely we must also look to install adjacent to a low voltage cable so that the column can receive its power supply. Other services (such as gas, telecoms and water) must also be considered. Guidance stated in HSE GS47 must be followed.

� The locating of columns adjacent to trees will always be avoided where possible. Tree branches and leaves can impinge on the light levels and also increase maintenance activities. It must be stated that it is not always possible to avoid this. NJUG guidelines will be considered.

� Lighting levels must be achieved and maintained, and moving columns on request from residents could mean that we do not achieve the dictated targets.

� Hazards and obstacles identified from the survey, such as drives, buildings and road layouts.

� Conflict areas – these are lit to higher levels and column positioning becomes more stringent.



InstallationThe works on site will follow a set process, which is explained in detail and chronological order below.The columns are not replaced in one visit, and the work will be completed over a period that can take up to and in some cases beyond six weeks. Every effort will be made to minimise disruption and it is important to remember that works will be taking place on a large number of roads at the same time. You will also see barriers on site and numerous visits whilst the work is undertaken.

If barriers are out on site guarding excavations, yet there are no workmen, this does not mean that the site has been abandoned or forgotten. It means that the next part of the process will be carried out imminently. All parts of the process required specialist skill sets and this is why numerous visits are required.

Please remember, this is a huge task with approximately 56,000 units being replaced over a five year period. Although we work as quickly as we can to the highest standard possible, it is inevitable that you will see works going on throughout the County. Providing that work sites are left in safe conditions when unattended, this is absolutely normal.

Marking out � Once the final drawings are issued, the designer

responsible for the drawing goes out onto site and marks out the position of the new street lights with a circular mark on the ground in non-hazardous marking paint.

� The designer will also mark columns to be removed by affixing a laminated notice.

� It must be noted that it is not always possible to install the column where it has been marked. Underground services drawings are not always 100% accurate and the services may block the proposed column position.



Column install � Upon receiving the construction drawings from the

design team, the first stage for the operations team is to send a column install crew to dig small holes and install the lighting columns without the lanterns attached.

� The final position will be subject to the presence of underground services.

� Please note from the picture (right) that the new column is situated adjacent to the existing one and the new lantern is not yet installed.

Lantern install � For the next part of the process, a team of

electricians will fit the lanterns to the top of the pre-installed columns.

Excavation works � Once the new column is ready, our excavation teams

will visit the site and dig a section around the column to expose an electrical supply. Although you can see the cables, they are insulated and perfectly safe.

� Normally the joint bay will be concentrated around the column but, additional trenching may be required if there is no electricity supply near to the new column. All of the excavations will be fully cordoned off with barriers in accordance with our stringent health and safety systems.



Electrical connections � After the appropriate electrical cable is exposed, a team

from the District Network Operator (DNO) will connect the electricity supply to the street light. DNO is a new term that is used for what once was referred to as the Electricity Board. The DNO that operates in Cambridgeshire is UK Power Networks.

� Although we plan and provide programmes of works for them, they are a self-governing body and do not come under direct control of Balfour Beatty. As such any columns you see with DNO signs are waiting for DNO works and we are unable to continue until the DNO complete their works.

� There can often be delays attributed with the DNO side of works, such as the discovery of unsafe cabling. This can lead to delays to the completion of works whilst the DNO use the opportunity to undertake improvements to their network.

� There are three forms of electrical connections which may be used:

New connections – connecting the column to the main electricity supply via a new joint.

Disconnections – making safe an old connection which is no longer in use.

Transfers – transferring the electrical supply from an old column into the new column.

Here you can see an exposed, but insulated and safe cable which has been transferred from an old column into a new column.

Removing the old street lights � Once the new lantern and column are in light, the

redundant column can be removed.

� Once taken out of the ground, the old street light is fully disassembled and all of the components are sent to be recycled.



Reinstatement � Once the old column has been removed, all of the

excavations will be filled and reinstated.

� To do this, our team of engineers will fill the excavation and top it off with a matching surface material. The surface will be fully smoothed and left in the same condition as it was prior to the works.

Quality control � On completion of the works, the installation is

inspected and tested to ensure that the installation complies with the appropriate standards and contractual requirements and is in working order.

� Any issues identified will be rectified.

Independent certification � Further to the checks above, all streets and installations

are put forward for an Independent Certifier’s (IC) check. The IC is an expert independent body that will inspect the quality of all works on a monthly basis.

� Results are reviewed and only street lights which have passed the stringent checks are passed as completed.

� Any street lights which fail the review are re-entered into the works programme and will be rectified as soon as possible. They will then be re-assessed in the next available check.

Completion � This completes the work in the street and it will be

returned to its normal condition but with the improved lighting solution.



Site safetyYou will see disruption on site, and barriers deployed to cover excavations. This is a normal part of the process, and should not be called in for attention unless the barriers have been disturbed.

The pictures below show some examples of some safe and unsafe sites.

� If you see an excavation such as those with a green tick, do not worry, the site is safe and we will be there to finish the works as soon as we can.

� If you see a site like those with a red cross, this is unsafe! Please contact us on 0800 7838 247 and we will come to rectify it as soon as possible.

This site is perfectly acceptable, and is simply work in progress.

This site is dangerous, and Balfour Beatty should be contacted immediately.

This hole is open, and Balfour Beatty should be contacted immediately on the numbers stated on the barriers.

This excavation is safely covered by barriers.


CambridgeshireStreet Lighting PFIFrequently asked questions

We maintain 3,900 illuminated traffic signs



I’ve received a leaflet about the street lighting replacement work. What happens next?The leaflet indicates that the works will take place in approximately 40 days. You will receive an additional notification letter two to four weeks before Balfour Beatty commences work in your area. At the same time as this, the streets will be marked to indicate the new column positions.

In the meantime, if you wish to view the plans for works on your street you can visit www.lightingcambridgeshire.com. We would also encourage you to liaise with your local Council so that you can understand the overall impacts in your area.

When will you be doing work in my area?The website www.lightingcambridgeshire.com provides indicative timescales for when the works will be started. After accessing the website, click on the ‘New Lighting’ tab and find your street. This is an indicative high level plan and is subject to change.

What does the work involve?The work involves the upgrading of approximately 56,000 lighting units. They are being upgraded to a more efficient light source and in the majority of cases, the works will involve the replacement of life expired lighting columns. Where columns are replaced, excavations are required to transfer and upgrade the supply cables. Newer columns will not be replaced, and the lantern only will be exchanged.

Will the new columns be in the same position as the old columns?In most residential streets, the new columns will be located at the back of the footpath and as close to the existing column as permissible. If possible, this will generally be within 3m of the current column positions.

New columns on traffic routes and in areas that require a more uniform light may be in different positions. This is because the current lighting standards require a minimum light level and a consistency of lighting which may not be achievable without changing the position and spacing of the lighting columns. Additional lighting may be required for safety at road junctions.

If a new column is installed outside my house, will I be disturbed by light shining through my window?The latest design technology helps to ensure that light is mostly directed down towards the road and pavement – but there may be a small amount of backward light. If you feel that the light is too bright please contact our customer care team (either call us on 0800 7838 247 or email us at [email protected]) and we will carry out tests to ensure that the levels of illumination onto your property are not in excess of acceptable standards. A shield can be fitted to street lights where it is considered that the light level on a property needs to be reduced.

Who can I speak to if I have a problem with a new column location?If you have any issues with a newly installed street lighting column or would like to put in a request to move an existing column due to be replaced, please contact our customer care team.

Either call us on 0800 7838 247 or email us at [email protected]

A street light has been located in a tree, what can be done?Whilst every effort is made to avoid locating lights near to trees, in some circumstances it is unavoidable. Where this has happened, and the tree is on private property and over-hanging the highway, Balfour Beatty will ask the land owners to trim the tree or can arrange this on their behalf. If the tree is on public highway, and does not have a Tree Preservation Order, Balfour Beatty will trim the tree so that it does not impair lighting levels.

A new street light has been installed but it is not working, who do I contact?If an old or new street light on your road is not in light at night, please report it to us on 0800 7838 247 or email us on [email protected] and we will endeavour to fix it as soon as we are able to.



What do I do if I am concerned about the safety or condition of the works being carried out in my area?For all enquiries or comments regarding on site operations, please contact our customer care team (either call us on 0800 7838 247 or email us at [email protected]). For safety concerns, please contact us on the telephone number immediately.

Why are some columns being removed and not replaced?Under the terms of the funding for the PF I contract, Cambridgeshire County Council is required to identify savings of 10%. As part of this, a decision was made to reduce the lighting stock across the County by 10%.

As traffic routes are being completely redesigned (and any savings from more efficient design are already taken into account) removals can only be taken from residential areas. This means that some residential areas may experience 40% or more in street lighting reduction. The new installations are being constructed in accordance with the contract specification. These changes are in line with Authority’s policy and will greatly benefit and enhance the County.

Can the Council legally turn off lights?Yes. There is no statutory requirement on local authorities in the UK to provide public lighting, the law states that:

� The Highways Act empowers local authorities to light roads but does not place a duty to do so.

� The Council has a duty of care to road users and has an obligation to light obstructions on the highway.

� The Council has a statutory duty under the Highways Act to ensure the safety of the highway and this includes any lighting equipment placed on the highway.

� The Electricity at Work Regulations imposes a duty on owners and operators of electrical equipment to ensure its safety.

Why are the new lights white and not yellow like the old ones?The current yellow lanterns will be replaced with a new white light throughout the County, providing a brighter light which spreads further, illuminating more of the highway. These lamps are much more efficient and provide a white light which is clearer and safer for drivers and pedestrians.

Where can I express my views on the street lighting installation service?A questionnaire will be delivered to your house and is available online at www.lightingcambridgeshire.com/feedback.aspx which will enable you to make comments. All completed questionnaires will be evaluated with a view to improving the service to the public.
