Does your council publish road works on roadworgs.org or on its web site? This may tell you what the work is for (look for references to "nga").
Look at council planning data (should be published on council web site) to see if any applications have been made for DSLAMs in your area.
FTTC is often done with a fibre feed from a "remote" exchange as the "head end" so the fibre goes there and doesnt touch your local exchange. In the case of smaller exchanges in particular this is a very logical way of doing it.
Of course it is possible that they are just laying new cables are building new ducts which are nothing to do with FCCT.
