1.1.2 The Project

The proposed development at the University of Queensland, St Lucia is called the Advanced Engineering Building (AEB). The building is seven storeys with levels 1 to 6 comprising of laboratory, teaching, office and research space for engineering staff and students. Level 7 is the services plantroom. Building GFA is approx 24,000m².

This project is subject to fire engineering.

1.1.3 ESD Initiatives

Forming part of the design concept, all parties of the design team including architects and builders and project management team have committed themselves to achieve a 5 Star Green Star Education (v1.0). This is both a design and as-built rating. The hydraulic sub-cotractor will have specific obligations in relation to providing written documentation as part of the A-Built submission. Items will include copies of receipt of goods, material data sheets, commissioning and testing data in an approved format. The project is also targeting 5 star NABERS.

To achieve this, a variety of items have to be fulfilled and have to be demonstrated during an assessment process by the Green Building Council of Australia (GBCA). These measures include but are not limited to the following items:

a) The inclusion of high water efficiency rated tap ware

b) The installation of water meters for all major water uses throughout the building with a link to the Building Management System.

c) Rainwater harvesting and re use of water to serve toilet flushing and irrigation requirements.

d) Reduction of PVC – Typically all hydraulic services related PVC materials shall be replaced with HDPE or PPR where an alternative product to PVC exists.

e) All insulation shall be free of ozone depleting gases in manufacture and composition.

f) All adhesives and sealants will be low VOC.

g) All painted services are to be painted with low VOC paints

h) Undertaking building tuning during the first 12 months of building operation

i) Preparation and implementation of commissioning in accordance with CIBSE requirements.

j) Preparation of relevant services clauses for inclusion in a Building Users Guide.

k) Undertake Principal instruction on hydraulic services operation.

l) Conform to the Contractors Waste Management plan in specifically relation to recycling.

It is within the sub - contractor‟s responsibility to comply with and achieve the abovementioned keystones, as part of the ESD initiatives.

1.2 ROLES, OBJECTIVES & EXPECTATIONS

1.2.1 Obligations of the Sub-Contractor

In writing this Specification the Principal expects and relies upon the tenderers‟ possessing specialist trade expertise necessary to complete the works in accordance with documentation.

In addition, the tenderer has the following obligations:

a) To raise in good time, issues requiring design input or clarification from the Superintendent, particularly in respect to:

I. Interpretation of the Specification or drawings.

II. Problems in complying with the Specification.

III. Omissions from the tender documents.

IV. Suggested alternatives/substitutions.

b) To allow the design verification costs of the Superintendent when suggesting alternatives and departures from the Specification.

c) To certify compliance with Contract documents, including all variation instructions, at Practical Completion as required by this Specification.

d) To comply with the Quality Assurance requirements of this document and the project contract documentation

e) To certify compliance with Authority requirements.

f) To pay all fees applicable to the works.

g) Arrange for specialist suppliers to provide on site inspections, installation supervision and commissioning.

h) To obtain all Authority permits and certificates to allow the progress of the works.

i) To provide manufacturer‟s and workshop drawings in sufficient detail to allow proper fabrication, coordination and installation of the works.

j) To provide samples and prototypes where specified.

16.2 MATERIALS

Pipework to and from flumes and pumps shall be PVC pressure pipe rated PN 6, with solvent-welded joints. Adequate allowance should be made for pipe bracketry, ensuring pipes are secure and supported in accordance with the manufacturer‟s specifications. In particular, pipe bends and changes in direction shall be secured with adequate thrust brackets. Where pipes are installed vertically, from high level to flume inlets or sumps, they shall be supported securely along the vertical length, and restrained adequately against all thrust and movement, caused by flow within pipework.

Lining shall be non PVC based and comply with the requirements for VOC content and ODP emissions.

16.7 PUMP CONTROL PHILOSOPHY

The following philosophy shall be applied to flume pump operation:

a) Main In-Ground Sump Pumps

On manual start-up, these pumps shall deliver a low flow of 10L/s, to intitiate an overflow condition in the Header Tank. As flume valves are opened and flows from the Header Tank to the Flumes increase, the delivery of the pumps shall increase automatically to ensure that the top water level in the Header tank remains constant, and conversely as Flume valves are closed, the delivery shall decrease accordingly, until to the low flow condition is achieved. The pumps shall therefore be controlled from the top water level in the tank. The Control Panel housing the pump controls and VSD‟s shall be located on Level 1 at the Sump. The Control Panel shall include an emergency stop button.

b) Stepped-Spillway Flume Sump Pumps

On manual start-up, these pumps shall deliver a low flow of 25L/s down the stepped spillway of the Flume. The Control Panel housing the pump controls and VSD‟s shall be located on Level 1 at the Sump. A remote control panel shall be located on the Flume, to allow for adjustment of pump speed and therefore flow, by way of a dial or touch sensor, up to the maximum flow. The remote panel shall include an emergency stop button.

c) Large Tilting Flume Sump Pumps

These pumps shall be located in the large in-ground sump, at the Tilting Flume. On manual start-up, these pumps shall deliver a low flow of 5L/s down the Tilting Flume. The Control Panel housing the pump controls and VSD‟s shall be located on Level 1 near the Tilting Flume. A remote control panel shall be located on the Flume, to allow for adjustment of pump speed and therefore flow, by way of a dial or touch sensor, up to the maximum flow. The remote panel shall include an emergency stop button.

d) Plunging Jet Flume Pump

This pump shall be located in the large in-ground sump, at the Tilting Flume. On manual start-up, the pump shall deliver a low flow of 5L/s to the Plunging Jet Flume. The pump controls and VSD shall be located in the same Control Panel as those of the Tilting Flume pumps, on Level 1 near the Tilting Flume. A remote control panel shall be located on the Plunging Jet Flume, to allow for adjustment of pump speed and therefore flow, by way of a dial or touch sensor, up to the maximum flow. The remote panel shall include an emergency stop button.

SCHEDULES 29.

29.1 GENERAL

The following schedules have been prepared for tendering purposes and to convey design intent. They form a summary of the preceding Clauses in the Specification and must be read in conjunction with these Clauses and the Project Drawings.

Where reference Clauses are referred to, they shall be taken as the major Clause, but equipment shall also comply with all other relevant Clauses in the Specification.

Water quantities and temperatures may be changed slightly to suit the particular manufacturer‟s equipment, however full details shall be submitted for review. Changes shall not be in conflict with any By-Laws, Statutory Requirements (including BCA Section J where applicable), Public Health Requirements or the overall design in general including achievement of any energy compliance and Green Star criteria.

Pump duties have been calculated from typical equipment and have been given as a guide only.

The following schedules show details of hydraulic equipment only.

THE EQUIPMENT PAGES OF This schedule must be submitted with the tender offer in the current tabulated form with „tender‟ columns and rows completed.

Schedule of equipment submitted on alternate forms, manufacturers‟ data sheets, contractor work sheets, etc. will not be accepted.

Completion of the technical schedule for tender review does not constitute approval of proposed equipment nor does it absolve the requirement to satisfy the requirements of the specification.
