![]() If you do design specifically for SIPS, but later find the cost of building with SIPS is too costly then you are stuck with drawings that should be modified due to different wall thicknesses and detailing needs.Īlso, Being a composite structure SIPS structures are difficult to modify later (you cannot simply remove walls or peel back cladding to add extra wiring for example). This takes a significant amount of additional time and cost in design phase. SIPS works particularly well when the home is designed specifically to the standard panel sizes in order to minimise wastage. Every trade that deals with this unknown will want to add time and cost to your project cover the risk. Builders, Electricians, Plumbers, Engineers, Air Con Installers are just a few of the contributors to your home that will have to adjust to working with SIPS, and in our building industry unknown factors ring big alarm bells. It is not just about the SIPS install itself. There is a limited number of tradesman with experience in SIPS so it is hard to get a price for construction that isn't loaded with risk. These suppliers are relatively small without the large economies of scale to make SIPS pricing cost effective overall. WA for example has two active SIPS panel providers, both of which have their own product composition, module dimensions and installation methods. There is limited number of SIPS panel suppliers around which means that there is a lack of competition in pricing. At best, a saving of 1 to 3 weeks over a 6 month build isn’t significant enough to justify the extra cost and complexity of SIPS, especially if you have to wait for a production slot for your panels to be manufactured, checked, delivered to site and erected. A SIPS build house claims to achieve this in 1 to 2 weeks. Prefabricated Frames can be erected in under a week. A site based carpentry team can erect a two storey timber home structure and make it weather tight in around 4 weeks. In construction terms, erecting the building structure only accounts for a portion of the overall build program. The time saving may not be worth the additional cost of the SIPS products over timber frames. Here is what the process taught me about SIPS. I even designed a version of the house using SIPS and then got it priced for construction to compare with a timber framed home of equal performance. The SIP is a 1-day orientation programme to educate migrant workers on Singapore's social norms, their employment rights and responsibilities, Singapore laws and where and how to seek assistance.Some of the arguments for building with SIPS include:īeing open to new technology and innovation, I looked into it using SIPS my own house.
