RMIT Childcare: Construction Planning and Design - Electrical Services

This project focuses on the electrical and hydraulics services for the RMIT Childcare center located at RMIT University in Melbourne. The assignment provides a detailed overview of the building's electrical system, including power distribution, lighting, and appliances. It includes take-off quantities for various electrical and hydraulics works, such as distribution boards, conduits, wiring, power points, lighting fixtures, and switches. The project also discusses the application of measurement rules and standard methods of measurement, with a focus on the New Rules of Measurement (NRM) and their volumes. The document references relevant publications and provides insights into the construction planning and design phases of the project, including the electrical and hydraulics design considerations for a childcare facility. The assignment covers the different electrical components, from distribution boards and conduits to lighting fixtures and power points, and provides a detailed breakdown of the materials and labor involved. The project also mentions the importance of adhering to electricity rules and regulations, as well as the use of standard methods of measurement for cost estimation. The document is supported by figures and drawings illustrating the electrical services at the childcare center.

Various elements of the electrical and hydraulics services
RMIT CHILDCARE is a childcare center located in RMIT University along 17-25 LYGON STREET
CARLTON. The center can be accessed at the street level and is made up of four floors having an indoor
play area for the children at every floor alongside a rooftop play area.
The center is made up of five rooms
 Room 1 for 3 to 18 months old children
 Room 2 for 12 months to 2 years old children
 Room 3 for children aged 2 to 3 years old
 Room 4 for children aged 3 to 4 years old; and
 Room 5 which is meant for children aged 4 to 5-year-old
Room 5 is inclusive of a program for four-year-old kindergarten.
The building hence needs adequate flow of electricity that does not have any disruption to ascertain that
the building is functioning fully during the time it is occupied (Collins and Woerman, 2016). Electricity in
the build on is mainly used for lighting, fire system, air conditioning, elevators as well as appliances.
Higher current electricity is generated at the different power stations. The current that is produced is taken
through a step up transformer in order to avoid chances of loss of energy.

Electric transmission tends to serve as the link connecting power usage and production of power. The
electricity at high voltage is thereafter transmitted through overhead lines as well as underground cables
from the power plants to the substations (Hall and Greeno, 2017). The electricity having high voltage goes
through numerous reduction stages at the distribution stations prior to getting to specific buildings by the
use of step down transformers. The transmission stations are 500kV, 275kV as well as 132 kV even as
distribution voltages tend to be in the range of 33kV, 11kV as well as 400 or 230 volts. The voltage of
electricity is further stepped down as per the suitable usage in every space.

Application of the measurement rules
With regard to pricing up a given bill, each estimator tends to have his own ways, styles, methods as well
as preferences even though one single area that often remains to be consistent is the rules of measurements
that are used in pricing up the given bill. The most commonly adopted rules are generated by the Royal
Institute of Chartered Surveyors which has undergone significant evolution over time resulting into
possible confusion among the estimators.
Standard Methods of Measurement
Standard methods have been developed with time to ascertain all QSs abide but the same standard during
pricing of construction projects. Such are composed of a set of rules as well as guidance for the purposes
of the measurement to ascertain the same items are incorporated or excluded in every rate so there can be
accurate application of the costs of the elements. Standard Methods of Measurement can be form in
different forms globally and enable fairest competition type during the production of a Bill of Quantities
with the contractor’s prices being with the very content and bearing surprises that are not welcome.
The New Rules of Measurement
NRM is made up of three volumes that were generated depending on the UK practices adopting the same
elemental order and language even though changing detail and complexity ascertain easy usage. They do
not offer data despite being a tool that enabling capturing as well as measurement of data in a manner that
is consistent.
NRM1-Order of Cost Estimating & Cost Planning for Capital Building Works offers a system for
preparing estimates for pre-contract as well as cost plants with the use of elemental breakdown. The
objective of this is to enable the contruction professionals as well as client to notice the benefits of clear
and transparent cost data that ought to allow building of a historic cost information database
NRM2-Detailed Measurement for Building serves as a direct replacement of SMM7 and is adopted for
pricing of Bill of Quantities and is composed of elaborate breakdown using the provided unit rates.

Elaborate guidance is provided on preparation of Bill of Quantities inclusive of elaborate coding as well as
work breakdown
NRM3-Order of Cost Estimating and Cost Planning for Building Maintenance Works adopted in taking
into consideration the running as well as maintenance costs of the building to aid with lifestyle cycle costs
and is made in such a way that it matches MRM1.This will tend to be more important as a result of the
sustainability push taking place globally and governments expecting the owners of builders to have more
responsibility.
