In a situation like you are describing they are invaluable but it is a safer environment with regards to reflectivity as people are looking for it and know there are people working and it is active site. On the road people aren't really looking for cyclists or really anyone sometimes they aren't expected there are usually higher speeds of vehicles (not always and some job sites and loading docks can have fast moving vehicles and they aren't truly safe).

I should note that I just got a ProViz Reflect 360 cycling jacket and I do love the visibility when light hits it it really shows up though the inside of the jacket that mesh I am not a fan of and the jacket is a bit heavy but overall great purchase but I wouldn't trade it for decent lights but is a great addition and certainly one I am so far glad I made. Being more visible is important and having your own methods for making yourself seen is the key having ridden and seen plenty of cars at night who don't use headlights for whatever reason having to rely on them to make me seen is not a good thing. I love pancakes of all forms except human ones made from me ; )
