Just found this in a 1992 KM:
>>>>>18
Who Qualify: Whenever a Kingdom Hall building project is undertaken, volunteers from the congregation(s) that will use the new or renovated facility and from nearby congregations provide the general labor force. Some of these become trained and thereafter qualify as experienced or even skilled workers so that they can submit Kingdom Hall Construction Worker Questionnaires.
19
Those specifically needed by the Regional Building Committees month by month are those who have experience in the construction trades and who volunteer to assist with needed Kingdom Hall construction. These must be in good standing in the congregation and approved by the local body of elders. If you are in this category, could you arrange your affairs to assist with this feature of Jehovah?s service? (Neh. 4:6) If so, obtain a Kingdom Hall Construction Worker Questionnaire from the presiding overseer or secretary in your congregation and submit it right away.<<<<<<
I'm surprised.
