    Who dream'pt this up then? Some spare lastminute.com dosh washing around in the Cooncil methinks?

    1. This outlines the supply & installation of bi-directional solar LED lights along the Union Canal towpath.

    2. The location of the sections of towpath are:

    LOT 1 - from Viewforth over bridge to the Harrison Road over bridge
    LOT 2 – from Harrison Road over bridge to Ashley Terrace over bridge
    LOT 3 - from Ashley Terrace over bridge to North Meggetland over bridge
    LOT 4 - North Meggetland over bridge to Allan Park Road footbridge
    LOT 5 - from Allan Park Road footbridge to Slateford aqueduct

    3. The proposed extent of the installations are shown on a map included with the tender documents.

    4. The tenderer is deemed to have inspected the site and made themselves aware of any special circumstances.

    5. All materials and equipment shall comply with relevant British Standards specifications.

    6. The contractor shall include for any material and works which may not be specified but which are implied and necessary for the satisfactory completion of the installation.

    7. All work must be carried out to a standard acceptable to the City Development Department and British Waterways Scotland. The method of installation must receive British Waterways Scotland and Historic Scotland approval via a Method Statement which must be provided to CEC within 2 weeks of the tender being awarded. The Method Statement should detail a method of installation that anticipates:

    - no damage to the monument (i.e. the historic structure of the canal);

    - no extrication of water from or discharging of water in to the canal;

    - no use of heavy machinery along the towpath; and

    - the towpath remaining open during the works.
    (2) EQUIPMENT
    1. White LEDs are to be embedded along the edges of the towpath at 10m intervals in pairs to delineate it for pedestrians and cyclists when light levels are low (i.e. from dusk until dawn). The towpath is generally around 1.8m wide, has a type 1 base of 75mm depth and is surfaced with bitumen (50mm)/Fibredeck (10mm). It is known that there are utilities along significant lengths of the towpath below a depth of 135mm from the towpath surface. The units should be positioned 100mm from the path edge.

    2. Due to the historic monument status of the canal LEDs are not to be installed under bridges or on their approaches (for the length of the masonry training walls). Either side of the bridge approaches 4 pairs of red solar bi-directional LEDs should be embedded along the towpath at 5m intervals at its edges instead of white LEDs. The locations of the over bridges are shown on a map included with the tender documents.

    3. In line with the middle of the access points a pair of green LEDs should be installed, one on each side of the towpath. Either side of these LEDs there should be 2 pairs of red solar bi-directional LEDs embedded along the towpath at 5m intervals at its edges instead of white LEDs. The locations of the access points are shown on a map included with the tender documents..

    4. The LED units should be installed by coring of the towpath surface and securing with epoxy resin. The LED units should sit flush with the towpath and have a low, smooth, profile. The LED units should be no larger than 150mm in diameter.

    5. The LED units' power system should be self-contained within the unit and switch off automatically during daylight hours to conserve energy. The LEDs must be visible for at least 500m where there is no obstruction.

    6. Contractors may propose the make and manufacturer of the lights and these will be assessed according to the Method Statement Award Criteria (No.2). The City of Edinburgh Council is looking to appoint one contractor to supply and install the Solar LED lighting for the lots as stated in our tender document. The City of Edinburgh Council encourages small, medium enterprises (SME''s) to enter into partnership agreements as stated in 1.20 of this tender.

    "Bi-directional solar LEDs should have the ability to be recharged and perceived even through thick overgrown undergrowth and multiple canine waste depositions."

    Nice slippy 15cm plastic lumps underfoot and underwheel should at least encourage more people to go slowly on the approaches to the bridges.

    Ah they have similar lights to these as cats' eyes now on the Lang Whang. I was amazed one night returning from East Calder to discover my CatEye was lighting up the cats' eyes for miles ahead. THen Druidh told me that they are solar powered. Spoil sport.

    They were quite bulbous to begin with and you tended to cycle around them but bits have brken off or been flattened so you can take a straight line now.

    I know we've talked about this before, but was there a planning decision? do they need to consult? I'm not strongly pro or anti (can see good and bad aspects), but as my flat overlooks it, I would at least like to have been consulted.

    Amusing that, again, the bit which needs attention (the bridges) is not treated while the bit which is foolproof is now to be fitted with lights... sigh!

    Maybe they'll do something about the lack of retroreflectives on the chicane gates for that interminable winter darkness.

    The cobbled bits under the bridges do encourage you to slow down, but they don't half shake your bike to pieces in the process.

    I observed on the other thread that it would have made more sense to cobble the approaches, but have the actual conflict zone in something with a normal amount of grip.

    I agree on the reflective gate option, although last time I went through one set had been torn open (with signs of motorbikes having used the path).

    Float the lights IN the canal for the guys who drove on the ice...

    hmmmm....out my window I can see two blokes in tracksuits with a long tape measure who appear asking a grey-haired pedestrian for advice/directions?

    Wonder if they are bidding on this? Not sure they inspire confidence!

    Dave - the Union Canal is a scheduled monument. This means that all its original features, including the cobbled areas under most bridges, are heavily protected from development. That is probbly why the lights will not extend under the road bridges or the cobbles ever be repalced with a nice smooth surface.

    SRD - British Waterways, which owns the Union Canal, is a statutory undertaker. This means it can undertake all sorts of canal related development on "operational land" without the need to secure planning permission (Classes 35 and 36, Town and Country Planning (General Permitted Development) (Scotland) Order 1992 - if you want chapter and verse). So installing these lights might not require planning permission.

    I'm not saying any of this makes any sense to current users of the canal - but there is a reason for it.

    Ah, interesting. That must be why they've also failed to treat the cobbles over the two aquaducts (which are in quite a dangerous state, IMO).

    Every day a schoolday!

    @ Dave,

    I just dismount and walk. The sight of a 100ft drop on one side and a potential splash on the other leave me wanting at least 3 points of contact at all times ;-)

    Has the tendering completed for this LED light on the canal thing, do you know? Someone's been doing some very precise marking out on the towpath today. Around Meggetland, there's a regular pattern of white spots each side of the path, and at every junction the spots change colour to green (to indicate the junction approaching) and red (for the very middle of the junction).

    This is really going to look like a runway or a motorway when it's done.

    These have now been installed as far as Harrison Park. The spraypainted dots continue on to Meggetland

    I unexpectedly ended up staying at work until 4AM last night. Er. This morning (internal clock now completely busted)

    Anyway, as it was unexpected I just had my "it's a bit dull / it's raining / there's a haar / it's getting dark" rear light with me. However there appeared to be a general lawlessness and disregard for authority going down so I decided to sneak carefully home in the dawn without a white light up front :O

    But it takes more than being subjected to 19 hours of rolling-rioting coverage on News 24 to lose all bearing of your inner moral compass so I kept to the cycle path where possible.

    This meant I ended up coming along the canal for a bit as far as Leamington - and for the first time seeing the lights in all their glory.

    They are really cool. Bright and effective, without being dazzling (the street and building lighting around the canal does that for you).

    However there were 2 teeny-weeny little problems with them...

    1 - they don't extend to under the bridges. Which is just silly as that's probably where they'd be most useful, because it's where the path is narrowest

    2 - they are red alongside all the entry/exit paths and in the run up to the bridges. But not at the speed chicane gates. It's OK if you're expecting them, but an unwary or inebriated cyclist might happily follow the white trail of fairy lights and ride smack into the black-painted fences across the path.

    They look really nice - unfortunately the night setting on my mobile phone wasn't having any of it and I couldn't get some pictures, but I'll take my camera and gorillapod tonight and try for some shots on my way home tomorrow morning (with front light of course).

    "might happily follow the white trail of fairy lights and ride smack into the black-painted fences across the path"

    But at 6mph they won't hurt themselves much...

    And of course they will dismount and walk through them...

    This picture "sort of" came out. But in reality, much brighter. You will have to click link and use your imagination a bit though!

    "This picture "sort of" came out."

    Thought that was the black cat in the coalhouse joke pic, but the bigger version is quite impressive.

    Today spray-painted dots have appeared on the towpath between the Slateford aqueducts. I assume funding's been found for an extension of the lights.

    Interestingly (well, a little) there are no dots on the shorter newer aqueduct over Slateford Road. There's a lead-in of red dots on each side. Presumably they can't/aren't allowed to drill holes for the lights in the aqueduct.

    EDIT: Looks like they're doing LOT 5 in the spec at the top of this thread...

    The lights are now in place right up to the start of the big viaduct/aqueduct. There has been some chat on towpath as shared path etc. It does have a disadvantage in that you could get very wet along with your bike on one side of it but I feel that once you leave these lights behind and get across the aqueduct/viaduct the issues of showing your adherence to the accepted communal nature of the route is not so intense. Some joggers, dog walkers, the odd baby in a pushchair but generally traffic thins out and it is just cyclists going to and fro Heriot Watt - after the Heriot Watt turn off you would be lucky to meet another soul, even in these hyper busy weeks of the fair weather commuters coming into play. Path tarmaced til Heriot Watt and dry until Addiston Farm turn off. Little damp after that in stretches until Falkirk then it gets wet....

    Today the towpath has been marked with yellow splodges all the way from Hailes Quarry Park to the aqueduct at Slateford. These are spaced like the LED lights closer to town, with a circle for most marks and a cross where I'd expect a red LED.

    I don't know if these are to mark installation, or part of a tender process, but either way it's clear that someone is thinking of taking the lights all the way to Wester Hailes.
