§ 120-l. Letting of contracts. 1. Whenever any work to be performed or   materials  to be furnished in or about any improvement to be made by two   or more municipalities under the provisions of this act shall involve an   expenditure of any sum of money  exceeding  five  hundred  dollars,  the   municipal  bodies  or boards of the contracting municipalities, by their   official action  taken  in  joint  meeting  as  herein  provided,  shall   designate  a time when they will meet at their usual place of meeting to   receive proposals, in writing, for doing  the  work  or  furnishing  the   materials, and such joint meeting shall order the chairman and secretary   thereof  to  give  notice,  by  advertisement  inserted  in  one or more   newspapers  published  or  circulating  in  the  municipalities  jointly   contracting,  at least two weeks before the time of such meeting, of the   work to be done or materials to be furnished, of which at  the  time  of   such  order  they  shall  cause  to be filed in the office of such joint   meeting particular  specifications;  all  proposals  received  shall  be   publicly opened by such chairman in the presence and during a session of   such  joint  meeting,  and  of  all others who choose to attend the said   meeting; not more than one proposal  shall  be  received  from  any  one   person, directly or indirectly, for the same contract work or materials;   and  the said joint meeting may reject any and all of said proposals and   direct its chairman and secretary to advertise  for  new  proposals  and   accept  such as shall in the opinion of a majority of the municipalities   represented in said joint meeting be deemed most  advantageous  for  the   said  municipalities,  subject,  however,  to  the  reservations  herein   provided; the board may require  a  bond  or  deposit  from  the  person   submitting  a  proposal,  the  liability of such bond to accrue, or such   deposit to be forfeited to the municipality, or municipalities, in  case   such  person  shall refuse to enter into a contract in accordance to his   proposal. The proposal so accepted shall be reduced  to  a  contract  in   writing,  and  a  satisfactory bond to be approved by such joint meeting   shall be required and  given  for  its  faithful  performance,  but  all   contracts when awarded shall be awarded to the lowest responsible bidder   offering  satisfactory  security;  this  section  shall not apply to any   engineer or agent of the joint  contracting  municipalities  engaged  in   supervising or directing the work of such improvements.2.  Whenever  a security bond is posted by a successful bidder for the   faithful performance of a municipal project under the provisions of this   article, for which state aid is approved, the name and  address  of  the   bonding  company or person issuing the security bond, the number of such   bond, and such other  information  as  may  be  required  by  the  state   department  or  agency  responsible  for  supervising  the  aid  program   regarding the project,  shall  be  transmitted  to  such  department  or   agency,  where  it shall be reviewed to determine its authenticity prior   to the award of such contract. The original of such bond shall remain in   the office of the municipality.  Upon  request  of  such  department  or   agency,  the  superintendent  of  financial  services  shall render such   assistance as is necessary to determine the authenticity of the security   bond.
