3. Hard flooring

Since people have to walk around their own apartments, you should be able to demand that their floors are insulated so that you don’t have unwelcome noise every time they do.

Protecting the residents’ enjoyment of their lot should mean that no timber or hard surface flooring is to be installed without proper consideration by the owner's corporation. All proposed hard surface flooring installations must receive written approval prior to commencement of the works; including any conditions imposed by the owners corporation.

You can find great variation in guidelines and by-laws. It is recommended that the owners corporation get an acoustic test to determine the noise characteristics of the floor/ceilings in the building. This is so that potential renovators have an understanding as to what they may need to do to meet requirements.

“And finally, I attach a table from our original successful anti-timber litigant which shows that NO timber floor provides the same sound insulation as carpet on a quality underlay. That could be the basis for justifying any by-law you may plan to propose. By the way, the higher the figure the worse the noise transmission and it’s worth noting that a polished concrete slab doesn’t even meet the minimum BSA standards.”Jimmy Thomson, Flat chat

 

Common Guidelines to use when selecting the proper IIC rating for your space:

IIC 50 – The least amount of impact sound transmission reduction considered effective. Some occupants would be dissatisfied with this level of sound transmission.
IIC 60 – Considered a medium level of impact sound transmission reduction.
IIC 65 – Considered a high level of impact sound transmission reduction that would satisfy most occupants

Depending upon the construction of the building, the use of floating floors and acoustic underlays may provide the necessary insulation. Be aware however, that the documentation of the performance of various underlay may assume a dropped ceiling. If your building ceilings are not dropped (i.e. they are a basic concrete slab) you will not get anywhere near the proposed performance.

If a by-law is required to regulate what kind of flooring can be installed on the floors of lots, get advice very early on. It is much more difficult to fix a problem once it has arisen than to prevent the problem from occurring in the first place. Remember, that even if a by-law as to flooring is complied with, there may still be noise. 

Works Guidelines

All apartments in Example Tower were originally designed and built with carpet as the standard floor covering. There is a concrete slab with no suspended ceiling above and below apartments. This design means that under By-Law 14 carpet is the preferred floor covering for all rooms except kitchens, bathrooms and toilets to ensure the ‘peaceful enjoyment of the owner or occupier of another lot’. Hard floor covering (tiles, floating wooden floors, parquet etc) are only permitted in the lounge/living areas of your apartment as long as they do not interfere with the ‘peaceful enjoyment of the owner or occupier of another lot’ (see By-Law 14). Hard floors will not be approved for bedroom areas due to noise transmission at night. The Executive Committee has assembled a number of installation methods for hard flooring that may meet this requirement. Copies are available from the Building Manager.

You may only install hard flooring in such areas if you agree:

i)     after installation is complete, to allow the Owners Corporation to conduct an acoustic isolation test between your apartment and the one directly beneath you;

ii)   to pay all costs associated with the test which is to be conducted by an accredited member of the Association of Australian Acoustical Consultants;

iii)should the test indicate an acoustic isolation worse that the standard (6 star rating) to pay for the complete removal of the hard floor and installation of carpet or a satisfactorily insulated hard floor;

iv)  should it become apparent that the hard flooring interferes in any other way with the 'peaceful enjoyment of any other lot', to pay for the complete removal of the hard floor and installation of carpet or a satisfactorily insulated hard floor.

Tiles and other hard flooring materials may be laid in kitchens and bathroom. However, in the case of bathrooms, due to the possible compromise of water proofing membranes, details the replacement material and the manner of replacement must first be assessed by the Executive Committee.

I the undersigned hereby warrant that I have read the GUIDELINES FOR BUILDING WORKS (February 2009) and agree to comply with all of the conditions and limitations imposed thereby.

ADDITIONAL WARRANTS (IF APPLICABLE)

HARDFLOORING IN DESIGNATED PLACES

As the work applied for entails installing hard flooring surfaces other than in a kitchen, bathroom or toilet, I hereby warrant that, after the new floor is installed, I shall pay for acoustic testing and will remove the hard floor and re-install carpet if it is found to provide inadequate acoustic installation.

What Members Say

"The whole strata community owes a huge debt of gratitude to you and the OCN executive. Much appreciated."

Robert, Darlinghurst

"I am very pleased with my membership of OCN, the discussions through sharing emails is very valuable in increasing my knowledge of strata living, the laws and EC responsibilities. I think I am better armed to tread the minefield of the managing agent responsibilities and the necessary action of the EC to monitor the contradictory interests of the agent."

Jim, Wollstonecraft

"I so appreciate being part of the OCN email forum. It provides a great opportunity for sharing ideas and learning"

Ingrid, Neutral Bay

"I must say that I have enjoyed and found consolation in the discussions that have been part of the email chain (forum). I did attend one general meeting and found that it was informative and the people "running the show" were knowledgeable and dedicated to the tasks that had taken on. In short, well done. You and the committee have and continue to support the Strata Community in a very professional manner."

Greg, Parramatta

"Nothing is easy in Strata World and we have been in building defects “mode” for some years – hopefully almost at an end but that process has been most demanding and difficult but again – greatly helped by the experience and wise counsel of other members of OCN."

Pat, St Leonards

"Keep up the good work, as many (if not most) strata schemes need your help, advice and representation at all levels of government."

Jann and John, St Ives

"I belong to OCN because of its professionalism.  I have found the meetings I have been to extremely well presented, to the point, and of course very topical and informative. Speakers on the whole certainly know their topic.  My role of Secretary last year was certainly assisted with the coverage regarding TPG & other subjects. Member newsletters are also of benefit as the topics are specific to strata matters."

Graham, East Balmain

I have enjoyed attending the quarterly OCN meetings and the exchange of emails between other Executive Committee Members and think OCN is playing an increasingly important role as a voice for strata dwellers and representing us at Government level. I wish the organisation continuing success in the future."

Pauline, Kings Cross

"The [forum] response to my question was amazing and really useful.  The OCN community is wonderful so thanks."

Jenny, Killara

"I would like to thank you all for the important effort that you are all putting in to look after apartment owners and tenants. It is so valuable and you are heroes. I would not have been able to deal with my duties as a strata chairman without your advice and assistance." 

Angela, Mascot

"The OCN is invaluable – many thanks."

Bill, Surry Hills

"OCN is proving invaluable"

Sue, Neutral Bay

"Thanks to all at OCN for your continuing efforts to keep us up to date with current strata information and advice...it has been very helpful to us"

Kate, Coogee

"When my wife & I first encountered a problematic Executive Committee I heard that OCN was a great help (from a Strata manager whom I knew) so we both joined and have gratefully used the on-line information sources. We continued to happily rely on OCN’s assistance when we progressed to Committee status & later as Chair & Secretary of our Committee. I still use OCN in my current role as Treasurer."

Peter, Chiswick

"Thanks to OCN for being such a rich resource of trustworthy information about strata matters."

Peter, Chiswick

"I wanted to extend my personal thanks for the very informative & interesting event today. The OCN team did an outstanding job in the organisation of this event & I enjoyed it thoroughly. The quality of speakers, the flow of conversation & interaction from the attendees - first class …& of course, the amazing Jimmy T - always a delight."

Sue, Epping

"OCN does a great job in providing a really valuable service to Strata owners."

Lois, Wollongong

"I am sure my appreciation of your good works is echoed by many in the Stratasphere. Keep up the good work."

John, Elizabeth Bay

"Once again, being able to discuss such things through this forum, helps clear the mind, puts things into perspective and helps one to understand their rights and to form a strategy if needs be. As a simple EC member trying to do what is in the best interests of lot owners, I truly value OCN and am grateful."

Pamela, Point Lookout

"The OCN is probably one of the best, most informed and most informative groups I have been involved with."

Alan, Maryville
