It is intended that any existing BAS controls for systems and equipment affected
by
work of the project shall be replaced with new electronic DDC controls, including field
devices, wiring, installation, software, programming, and testing.

Refer to
section
25 9000, "Sequence of Control", for a description of the operation of
modified
building systems and for lists of building automation
sequence of control and point

lists.

so that it is easier
to communicate with other control systems. Some upgrading has
been
accomplished by The UHL

Company during the past several years, and other work still
remains. The upgraded system in the

DEMOLITION / MOVING
OF EXISTING CONTROLS

A.

Demolition of an existing control system shall include removal of con
trols which do not remain
as part of the building automation system, all associated abandoned wiring and conduit, and all
associated pneumatic tubing.


B.

The TCC shall ask the Owner to identify any equipment which is to be removed that will remain
the property of the Owner. (All modules not being reused shall be turned over to
Mn/DOT
) The
TCC shall transport the Owner
-
retained equipment to a location on th
e site chosen by the
Owner. The TCC shall dispose of all other equipment which is removed.


C.

Instructions for demolishing, moving, reusing and adding to the existing BAS and it’s network.

a.

Before demolishing a module or moving points this contractor shall
coordinate with the
General Contractor and
Mn/DOT
’s Building Maintenance Supervisor, Al Weibye, for the
Detroit Lakes Hdqtrs.

b.

All modules shall be de
-
energized by
Mn/DOT

before removal by this Contractor.

c.

Demolishing, and removal of all existing controls
shall be finished before the general
demolishing takes place in the area, so as to recover existing modules and sensors in
good condition .

d.

All points (relays, transducers and sensors) which are to be moved from one module to
another may be reused.

e.

All mod
ules and points that are to remain shall be protected from dust and damage during
construction in the area.

f.

All demolished modules and their input sensors shall be recover and store in a manor
which will allow them not to be damaged and retain their funct
ioning condition. At the end
of each Phase of work the Contractor shall then give the equipment to the Building
Maintenance Supervisor, Al Weibye, for the Detroit Lakes Hdqtrs.

g.

All modules including existing modules shall be given a new network communi
cations wire
(CMnet). Any module CMnet may connect to any other module except for the U
-
line
modules. When removing a module this contractor may need to reconnect the CMnet if
the CMnet wiring also leads to other modules which are to stay in that Phase o
f the work.

This contractor may reuse the Cmnet conduits in the shops and vehicle storage areas.

EXISTING CONTROLS:
(EDIT)

Existing controls which are to be reused must each be tested and calib
rated for proper operation.


Existing controls which are to be reused and are found to be defective requiring replacement, will be
noted to the Owner. The Owner will be responsible for all material and labor costs associated with their
repair.
