SECTION 108
PROSECUTION AND PROGRESS:

108.01 Subletting of Contract. The Contrall-
tor shall not sublet, sell, transfer, assign, or dispose
of the Contract or Contracts, or any portion without
written consent of the Division. The Contractor will
28

be perOlitted to sublet a portion of the Contract,
however, the Contractor's organization shall per-
form work aOlounting to not less than 50 percent of
the total contract cost. Any items designated in the
Contract as "specialty items" may be performed by
subcontract. The cost of specialty items so performed
by subcontract may be deducted from the total cost
before cOOlputing the amount of work required to be
performed by the Contractor's own organization.
The agreement between the Contractor and a
subcontractor will be approved by the Division prior
to the subcontractor beginning work.
The calculation of the percentage of subcontracted
work shall be based on the prime contract unit prices
rather than subcontract unit prices. Proportional
value for a subcontracted partial contract iteOl shall
be verified by the Engineer. For the purpose of
calculating the value of subcontracted work, the cost
of procuring materials and Olanufactured products
can be included in either the prime contract or
subcontract. However, when a firm both sells
material to a priOle contractor and performs the work
of incorporating the Olaterials into the project, these
two phases shall be considered in combination and
as constituting a single subcontract.
Subcontracts, or transfer of Contract shall not
release the Contractor of liability under the Contract
and bonds.

108.02 Notice to Proceed. The Contractor
shall not COOlmence work prior to the issuance of a
Notice to Proceed. The "Notice to Proceed" will
stipulate the date on which Contract tiOle com.
mences. When the Contractor proceeds with work
prior to that date, contract time will COOlOlence on the
date work actually begins. The Contractor shall
comOlence work under the Contract on or prior to the
20th day following the date of award, or in accor-
dance with the selected start date allowed in the
special provisions.

108.03 Progress Schedule. The Contractor
shall submit a Progress Schedule within 10 working
days of the date construction is authorized to
proceed. The Contractor shall revise the Progress
Schedule, within 10 days of the Engineer's written
request, to show any substantial change. Failure to
subOlit a revised schedule will result in withholding
progress payments.
The Progress Schedule Olay be subOlitted on
Contractor furnished forms or on forms supplied by
the Division. The Progress Schedule shall consist of
a COOlprehensive Bar Chart and a Methods State-
Olent, each on a separate report.
(a) The Comprehensive Bar Chart shall show,
as a OliniOluOl, the following:
1. The salient features, as listed in the
special provisions, listed in the order in
which the Contractor proposes to carry
out the work.
