Half the money seems extremely high for a FIOS project. However, it all depends on the hours of involvement that the manager dedicated to this that you might think the person may be meritorious of some bonus, even a larger oner at the end of the year for his/her efforts if you were to offer one.

If you read the contract that you have with the management company, it may stipulate that the manager may have to be compensated for overseeing a capital improvement project. FIOS is a project whose installation may run into thousands for a property. In some cases, there is drilling in basements and you wish to ensure that all the holes are completely patched with fire-rated caulking; also, you wish to have wire mold appropriately placed and covered; finally, there is liability in the event the workers are not careful in laying the cables on the floor without regard for residents. If the installation work is done smoothly and well, it may be thanks to the coordination of the manager and the superintendent.

Many boards feel that these improvement projects do not take time to oversee, but they may consume time. Otherwise, Board members should be highly involved to ensure that the installation met your standards and to avoid further compensation to the manager.
