I believe the answer is:
builder
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">construction worker</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for builder that I've seen before include "Bob the - - (TV)" , "Constructor" , "Construction worker" , "Bob, eg" , "One involved in construction" .)
