SB MAINTENANCE SCHEDULE NEEDED!
Does anyone know where we might find a template building maintenance schedule for a mechanical signal box?
We're looking to adopt Banbury North Signal Box (mostly brick, GWR type 7A) and Network Rail are asking that we have one. (yes, you'd have thought NR would have such a thing, but they've asked us for one).
The schedule needed is for the building envelope only (- no need for a schedule for the equipment). It's the normal cycles of inspection, painting and pointing sort of thing we need. Any help gratefully received

Following the professional builder's restoration of the fabric and structure of St Albans South box, including the external paintwork, concluded in early 2008, we started repainting the exterior in 2012. But the wet weather that year defeated us, and the external repaint was concluded in 2013 by employing a professional painter. We have to keep touching up odd bits, particularly at the south (staircase) end as this gets the worst of the prevailing wind, rain and sun, plus wear and tear on the stairs handrail. We expect to do a further complete external repaint probably 5 years after the last, ie in 2018.

The internal paintwork was done in 2008 entirely by our volunteers. The interior paintwork of the operating (1st) floor was cleaned and repainted mainly by one of our volunteers over the past Winter. We expect to repeat the exercise 'as and when' required, but probably not for another 7-8 years. The ground floor paintwork, where we have our museum display, is in reasonable order and gets a 'spring-clean' with a vacuum cleaner most years.

External brickwork: Examine yearly for loose pointing etc. It is very possible that the box was built with lime mortar but more recent repairs/repointing have been carried out with a cement mortar. Wherever/whenever possible, replace the cement mortar with lime mortar.

Roof/rainwater goods (ie gutters/downpipes) Check yearly for slipped/broken slates on the roof. Check gutters and downpipes (and associated drains) twice a year in Spring and after leaf-fall has ended for blockages, leaks etc. Repair any leaking gutter joints ASAP to minimise damage by water.

Have a look at https://www.historicengland.org.uk/images-books/publications/ - Historic England publish a lot of useful advice on the maintenance of historic buildings, often downloadable as a PDF file.

Best wishes in your endeavours - we'd be happy to entertain a party from your group at St Albans South, I'm sure!

I've just come across my copy of the BR Civil Engineering Handbook No.10 "Code of Practice - Cleaning and painting of Bridges, Buildings and Structures", 1954 edition. This goes into great detail about surface preparation and application of paint to a wide variety of surfaces - but does not give any guide to how often surfaces should be repainted.

One thing that may be of particular concern to your maintenance is to determine if any of the paint is lead-based. If it is, you will need to use personal protective equipment and other precautions when you do any work on such paint. It might be a good idea to see if NR can give you any information - they should have a register of hazards present at the box. (At St Albans South there is a short length of asbestos-cement troughing - every year or two someone from NR pops in to check it is still in place and in good condition!)
