Saturday 27 July
The all change in the title refers to the weather, we've gone from baking heat to miserable wet in less than 36 hours. Is it any wonder that the English are obsessed by the weather. Anyway, the bricklayers said it was too wet today, the mortar was washing out. There was, therefore, a slight shift in emphasis, the Gantt chart got shuffled, the critical path went awry, the project manager's hair turned a little lighter grey. All things being even, we still had a productive day.

Alastair is always first out of the blocks to get the mixer going so that the builders can make a start.

Raising the channel south wall on the down side is (was) next on the agenda.

Stuart went off to do the gardening, the vegetation has taken over at Gallery Crossing (to the south of the work site) and this needs to be cleared ready for any harvest traffic.

Back at the culvert, the old mortar on the down side south wall was was proving harder to shift than most of the other parts dismantled along the channel.

In the vain hope that the weather was going to get better, bricklaying did start. The forecast said 10% chance of rain, it didn't mention the 100% chance of heavy drizzle though.

This is where the plan gets modified, the forecast change in the weather hadn't materialised so the decision was made to do the concreting around the up side cess outfall walls.

Promotion to mixer operator brings with it extra responsibilities, no extra money though 😉

We have spotted that the copings on Bridge 11 wing walls need to be re-seated, there are cracks along the mortar joins. Roger decided to investigate the up side north end, in the vain hope that just the large corner would need to be refitted.
|
Sometimes it's best not to look 😊 |
The mortar in the middle void of the coping must have been attacked by ants (or some other critter) there's definite signs of habitation in the patterns formed

We are proposing to lay a new pipe from Culvert 11B to 11A, currently the flow runs under the adjacent field where the pipe has collapsed. In readiness for this work the area needs to be cleared again, just in case the budget stretches to doing the work this year.

Using the wheel to measure the pipe run from Culvert 11B up to Culvert 11A arrived at 126 m, measuring on Google Maps satellite imagery shows 122 m, that's a margin of error we can work with.
|
Is the unicycle accurate? |
The up side north wall only needs to have the top headers added now, the decision to take it back down to the water level has paid off.

Did we mention it was the Heritage Diesel Gala this weekend, the intensive timetable meant we had more passing trains than usual for a Saturday. With the thick overcast the headlights made spotting approaching trains a lot easier.
