Build Photos

Here are a few photos of the site from Friday 9th November...

Keeping the rock face beautiful

The houses in terrace D at the east end of the site look out on a sandstone rockface to the north (and over the river to the south).  The problem with building houses at the bottom of a rockface is we have to ensure that residents and their visitors are not put in danger from possible rockfalls!

A common way of dealing with this is to cover the entire rockface with wire netting - not particularly attractive, as this photo from a different site shows.  Unfortunately this is the type of solution that the first contractors we asked to look at the risk proposed...  In our case the stone wall above the face would have been covered in net too.
However we now have a more acceptable proposal (below) which looks at the risk that each particular section of rock presents and uses bolts of varying lengths depending on the condition of the rock.  We are now looking to progress a solution of this type as quickly as possible, so that we can get on with building Terrace D.

It's November and the first house walls are six foot high

Hot off the press, these photo's were taken just before today's progress meeting with the contractors and design team.  The walls of terrace A are now rising - one leaf of the cavity wall goes up, then the insulaltion is fitted with the basalt cavity ties passing though it, before the other leaf of the wall is built.


Terrace A is actually a couple of weeks behind programme at the moment, but enough progress has been made to get a good feel for this part of the street, and also to see that there will be a good view from the north bedrooms of terrace A over the bike store to the fields and trees beyond.

The next picture shows the retaining wall that will be at the back of the common house toilets and guest rooms being propped whist it is underpinned.  The floor of the common house main building is in the foreground.

Meanwhile the rock anchoring to the retaining wall behind Terrace F, the 3 storey units, has been completed.  This wall isn't going anywhere!



Terrace B is also making progress.  These are the foundations of plot 10:-


The weather hasn't been the best, and there is a lot of water about.  Fortunately the fishing season is now over and no one else needs to pass through the site

We've had some sample gabion baskets made up.  The one on the left is made up of the crushed remains of the buildings we demolished whilst the one on the right is from sandstone from the site.  Unfortunately there is unlikely to be enough material from the site suitable for putting in gabions, especially as it is unlikely that we will be able to use brick at the front of gabions due to the risk of weathering...
so we are also looking at using some imported material.  In the photo below we have limestone in the gabion basket to the front and sandstone in the one to the rear.  Despite the fact we are in a sandstone area in Halton Gorge, the nearest quarries, around the Kellets, are limestone.  Ironically the sandstone has to be transported from a quarry near Chorley.  On the left is the reclaimed sandstone.  We are looking in more detail at the costs, aesthetics and environmental impacts of the various options before taking a decision.

The missing link - at the Lune Aqueduct

Five or ten minutes cycle ride downstream from Forge Bank, another construction project is well underway.  British Waterways are carrying out various repairs and improvements to the Grade 1 Listed aqueduct which carries the Lancaster Canal over the River Lune.

If you are reading this and don't live in Lancaster, you might not know that both the river and the canal have tarmaced cyclepaths alongside them, but until now they have been linked by some steep and narrow steps.



Not only are the steps being widened...


but also a new cycle path is being built up a relatively gentle ramp to link the riverside cyclepath to the towpath...


...emerging just before the canal crosses over the A683 Caton Road on another bridge.  
According to workmen on site, the ramp is due to open in January 2012


Why am I writing about this on the cohousing blog?  Because once the new ramp is open, it will be much easier to cycle from Halton to a whole host of destinations close to the canal, including the Dukes Theatre, canalside pubs, the Gregson Arts and Community Centre, White Cross and the Hospital.  The towpath isn't lit, so its not the first choice after dark, but the rest of the time it makes a excellent route to the whole east side of the city centre and beyond.

Latest pictures from the site

Okay, these photos are a few days old sorry - I only just got around to downloading them.  Block laying above floor level started on Wednesday so look out for more pictures next week...

The common house - you can see a black heating duct popping up through the  floor which will allow heat to be piped from the woodchip boiler and solar thermal panels on Halton Mill

The foundations have been laid to allow part of the building that will contain the toilets, laundry, guest rooms and play room to be rebuilt, this time with wheelchair access 

Here's the surface water drain coming through the common house.  We still have to fit electricity, heat, phones and TV alongside it.  The sewer goes a different way, fortunately

This is an example of what contingency is for.  We were going to reuse this gable wall, but having seen the state of the below ground section we are now going to have to rebuild it.  Steps will go up to Terrace F from the right hand side of this photo. 

At Terrace D the groundworkers are still removing rock, some of which will go in gabion baskets.  The rock removal is expected to take 3 weeks.

At Terrace F, sub contractors are installing rock anchors into the existing wall so that we can reuse it confident that it was not on the verge of collapsing.
