(a) "Persons" include an individual, firm, partnership, corporation, association or other organization, or any combination of any thereof.

(b) "Contractor" is deemed synonymous with the term "builder" and, hence, any person who undertakes or offers to undertake or purports to have the capacity to undertake or submits a bid to, or does himself or by or through others, construct, alter, repair, add to, subtract from, improve, move, wreck or demolish any building, highway, road, railroad, excavation or other structure, project, development or improvement, or to do any part thereof, including the erection of scaffolding or other structures or works in connection therewith.
