                                 Hydraulic Specification 25

All liquid retaining structures shall be hydrostatically tested for leakage.
Testing shall take place prior to placing of backfill around each structure and prior
to placing concrete benching, mortar toppings and tiling.

Prior to carrying out the hydrostatic tests, the Contractor shall remove all debris
from the structures; install temporary blank flanges, plugs or caps on pipework cast
through concrete walls; seal with temporary covers any openings in the concrete
below top water level and generally ensure that each structure is watertight and
ready for testing.

The Contractor shall supply water for the hydrostatic testing. The Contractor shall
be responsible for supplying and installing pumps and pipes to transfer the water
and to empty the structures on completion of the hydrostatic tests.

The structure shall be cleaned and initially filled with water at a uniform rate not
greater than 2 m in 24 hours. The water level shall be maintained for a stabilizing
period of 7 days to allow for absorption and autogenous healing of the concrete.
After the stabilizing period, the water level shall be recorded at 24-hour intervals for
a test period of 7 days. During this 7-day test period, the total permissible drop in
level, after allowing for evaporation and rainfall (if the structure is uncovered) shall
not exceed 1/500th of the average water depth of the full tank or 10 mm, whichever
is the less.

Any leaks including visible wet patches on the outside faces of the structure or
increased underdrain flow shall be rectified to the satisfaction of the Principal. The
structure shall be retested until it meets with the requirements of this specification.
No backfilling around the structure shall take place until these requirements are all
met. Repairs shall be carried out to the surface in contact with the liquid unless it
can be demonstrated that such repairs can be successfully carried out to the
external surfaces.
Upon completion of the test the Contractor shall empty the structure and dispose of
the water to the satisfaction of the Principal. The hydrostatic test results shall be
submitted to the Principal for approval.

                                 Hydraulic Specification 26

The contractor shall prepare the operation and maintenance manual as follows

FORMAT: The format of all Operation and Maintenance Manuals shall:

(a)   Facilitate the rapid detection of the cause of all faults and the recommended
      course of action for repairs,
(b)   Provide a simple and clear system for the safe and efficient operation and
      maintenance of the system throughout its design life.

The manuals are to contain all necessary information required for the safe and
economic operation of the services, and shall include:

(a)   System Purpose and Description (with illustrations/diagrams)
(b)   Preventive Maintenance Procedures (with illustrations)
(c)   Corrective Maintenance Procedures (with illustrations)
(d)   Repair Procedures (with illustrations)
(e)   Test Procedures
(f)   Illustrated Parts List (including a list of recommended spares holding)
(g)   Special Tools and Test Equipment
(h)   Schedule of Reference Drawings
(i)   Statutory Certificates as appropriate
(j)   Manufacturers Handbooks, and Data Sheets
(k)   Reference Drawings and Commissioning Data.

This section shall consist mainly of a non-technical but functional description of the
system and shall state what the system is designed to do and how it does it.
Reference shall be made to an appropriate diagram to indicate the system
configuration, the system's interface with other services systems and to identify
major items described in the following:


Preventative Maintenance Procedures
Preventive maintenance actions and procedures for carrying them out are to be
provided such that the systems can continue operation in economic safe, and
energy efficient manner.

Corrective Maintenance Procedures
Instructions are to be provided for all non-obvious removal, repair, adjustment and
replacement procedures.

Maintenance Schedule
A specific section of the manual shall be dedicated to a tabulated maintenance
schedule on a system by system basis. The schedule shall clearly indicate the
routine and preventive maintenance required on a cyclic basis and/or by system
indication over the design life of the system, with page references if necessary to
detailed sections of the manual.

                                 Hydraulic Specification 27

This section will provide information on repair procedures after fault diagnosis.

 Example CC TV – Carry out CC TV inspection of the sewer and stormwater
inground drainage systems.

This section shall provide a detailed listing and description of all system and
equipment tests to which reference is made from other sections of the manual.

All relevant sections of the manual shall highlight safety and environmental issues
(particularly hazards) clearly indicate procedures and/or special precautions
necessary to avoid them together with emergency procedures to deal with
unfavorable circumstances should they arise.

Comprehensive and illustrated parts lists shall be included in each manual,
including references to suppliers and manufacturers names and contact details.
Each part shall be referenced by a unique number within an integrated reference

Detailed lists of all special tools and/or test equipment required for the repair
and/or maintenance of the installation shall be provided.

During the construction time the contractor shall collect all necessary details &
prepare the as built drawings or sketches and give to Principle Representative
Regularly. If necessary CAD files will be provided to use only for to prepare the as
built drawings. This must show all pipe alignment from fixed planes or lines, depth
of invert from Finished Floor level, Invert levels, pipe sizes, all fittings details and
their exact location etc. This is to easily locate the pipes or fittings in the future
when necessary arises.


All necessary reference drawings, including a full set of Work as Executed
Drawings shall be included with manuals in A3 and A4 size as appropriate. Where
these drawings cannot be reduced in scale, they shall be neatly folded and
included in appropriate sections of the manual. Where a significant number of
drawings are required, the Drawings may comprise a separate volume. All
drawings shall be easily referenced from Text sections of the manuals.

A complete schedule of reference drawings shall be provided in the manual.


                                  Hydraulic Specification 28
Binders shall be 3 or 4 'D' ring, vinyl clad, sized to accommodate A4 sheets and
index tabs. Colour and embossing shall be as nominated by the SI.


The front and spine of each binder shall be machine embossed with the following
