A Big Day at Western Depot

By: Buffs with additional contributions from Andy P

An early start for WD volunteers on Monday.  There was frost on the Cotswold Hills promising a calm day with a forecast of sun later.  My car showed signs of an air frost with ice on the glass from the roofline to halfway down the windows.  The early rising sun became garlanded with a halo which grew ever larger as the light passed through the rising mist and hazy cloud.

The early cohort of volunteers had opened the gates and very quickly our vehicles and trailers were moved to the car park.  The scrap and general rubbish were loaded for disposal and the trench plates which cover the yard lifted to provide a more reliable surface for the mixer when it arrived.
Meanwhile Duncan and Andy P set about placing the re bar mesh in place prior to the pour. The mesh was supported on pieces of brick to ensure it was inside the concrete slab
An anticipatory quiet fell over the Western Depot. Barrows were lined up ready, spades and shovels were clean and close to hand. The last cups of tea had been drunk and gloves were being nervously clasped as the team waited for the mixer to arrive.  Time ticked by until the cry “it’s here” was heard.  The mixer was backed as close to the barn as was safe and the delivery chute fixed in place.  Anticipation turned to readiness only to be paused whilst the samples were taken.

A small amount of the mix was taken to the accompanying van for a slump test and for test blocks to be made.  For the slump test a conical mould was filled with the mix and tamped down.  Before the mould was removed the top of the cone was levelled then with a swift lift the mould was off and placed beside the concrete cone.  The cone did not slump but stayed upright and in shape. A good mix for us to lay.
And then the hard work began.  A whir of barrows and shovels went into action filling the space between the shuttering.  ‘Don’t stand still or your boots will be filled’.  The team barrowed, shifted, shovelled and raked for about an hour to get the concrete approximately level.  The ramp was filled and the extra slab by the carpenters shop was started.
On to the levelling with the power screeder. Jason had confessed to having laid concrete slabs before so he became the natural choice to drive the powered vibrating beam. Naturally it took a little to get going but soon a level surface began to appear. 
It became obvious that there was too much concrete for the fill and many barrow loads of concrete were removed into an ever growing fleet of barrows. (Where did you find them all, Kay?)
Until all was smoothness and it was time for lunch. (Note to self: Must remember to thank Leonie for bringing the most welcome cups of tea!)
To generate the final polish on the new floor a rotary power float was used. To say that this requires both skill and courage to operate belies the comedic scope of the tool.  The first attempts demonstrated that this beast could be a bucking bronco or a magic roundabout.  Eventually Jason mastered the beast and with help from Andy and Maurice who applied the water and the floor was polished to a flat and plain surface.
As this was a construction job with many wheelbarrows and shovels used there has to be a hands up picture so here it is:
Thanks to Will, Mathew, Jason, David, Vince, Andy, Duncan, Kay and Maurice; not forgetting Reg who managed it all beautifully by keeping out of the way
