When a concrete contractor needs to do any type of commercial concrete pumping on the grounds of a historic church, they must do so with great caution. Below are some tips that contractors in this situation should keep in mind.
They should ensure that any stained glass windows are covered before they begin
Many historic churches feature beautiful, intricate stained glass windows, which were produced and fitted centuries ago. Concrete contractors who need to, for example, pour concrete over a historic church's yard or car park must ensure that any stained glass windows that are facing their work area on the grounds are properly covered.
The reason for this is as follows; the old stained glass windows that are typically found in this type of building (many of which could be classed as artefacts, and are highly valuable, from an artistic, cultural and monetary point of view) could be irreversibly damaged if they any wet concrete that spews out of the concrete pump lands on them. This is because the removal of this concrete would involve using a tool with sharp edges to scrape it off, and this scraping motion could scratch the pane.
As such, concrete contractors working on projects like this must do their utmost to protect these windows. Depending on the windows' positions, this might involve these contractors using scaffolds or ladders to access and place plastic sheeting over these panes.
They should check the church's schedule to ensure that no weddings or funerals will be taking place whilst they're working
Historic churches, that have beautiful architectural features, are favoured by many people who want to get married or who need a place in which to host a funeral. It is important for concrete contractors to keep this in mind and to try to arrange to use their pumping equipment at a time when the church is not scheduled to be used for a wedding or a funeral.
There are two reasons why it would be inadvisable for a contractor to work during these events. Firstly, the loud sounds that the concrete pump will make could disrupt the funeral or wedding proceedings and upset those attending these events. Secondly, there is a chance that the pump might spray small drops of wet concrete onto the people as they walk into or out of the church; this could be distressing (particularly if the concrete lands on a bride or groom, or on a casket).
