§ 20-a. Purchasing  department or agency.  Each city, except a city of
  the first class having a population of one million or more  inhabitants,
  is  hereby authorized and empowered to create and establish by ordinance
  of the common council or similar legislative  body  and  to  maintain  a
  purchasing  department  or  agency.    Such  department  or agency shall
  consist of  a  purchasing  agent,  who  shall  be  its  head,  and  such
  assistants  and  with  such  salaries  as  the  body which is by charter
  authorized to designate the number of employees and  fix  salaries,  may
  from time to time authorize. The purchasing agent shall be appointed and
  removable  at  pleasure  by  the  same  official or body who or which by
  charter is now authorized to appoint the heads of city departments.  The
  purchasing  agent  shall  appoint and remove at pleasure such assistants
  and employees as may be authorized.
The purchasing department or agency shall purchase and be  responsible
  for the proper receipt of all materials and supplies, including those on
  which  bids  are  obtained  after  publication of notice pursuant to law
  unless the legislative body shall by  ordinance  otherwise  provide,  as
  well  as those purchased without the requirement of competitive bidding,
  for such departments, boards, bureaus and offices of the city  as  shall
  be  designated  in  the  ordinance  creating  the  department. Boards of
  contract and supply in second  class  cities  and  boards  with  similar
  powers  in  other  cities  and the common council or similar legislative
  body in cities which have no boards of contract  and  supply  or  bodies
  with  similar  powers, shall make rules and regulations not inconsistent
  with general laws or their charter, which shall prescribe the procedure,
  conditions, methods and practices that shall prevail in  regard  to  all
  purchases  of  materials  and  supplies  by the purchasing department or
  agency, and all departments, boards, bureaus and offices of the city for
  which supplies are purchased shall obey and comply with such  rules  and
  regulations.  The  purchasing  department  or agency may sell, under the
  direction of the board of contract and supply or any body having similar
  powers or the common council or similar legislative body in those cities
  which have no boards of contract and supply or body with similar powers,
  all property, real and personal, of the city not needed for  public  use
  and  authorized  to  be  sold. The purchasing department or agency shall
  have charge of such  storerooms  and  warehouses  of  the  city  as  the
  legislative body by ordinance may prescribe.
The  purchasing agent and such other subordinates of the department as
  the common council or other legislative body may designate, shall within
  ten days after appointment execute bonds to be approved  by  the  mayor,
  payable  to  such  city  in amounts to be prescribed by ordinance of the
  common council or similar legislative body contingent  on  the  faithful
  performance  of  the duties of their offices and for a due accounting of
  all property that may come under their care, custody and control.
