Fixed Price Screw Piers

FIXED PRICE FOR YOUR NEXT BUILD

Is it possible to fix the price of screw piers?

Being able to receive a fixed price for your screw piering is a valuable opportunity but not one that is available for all sites. Our experience is that many more builders can receive this peace of mind than apply for this option.

Traditionally, builders, engineers and designers consider inground costs as an expense that is mostly unknown and a potential area of financial friction. Our dual business model means Idealcorp is uniquely placed to potentially remove the “unknown cost” and fix the price of your screw piering project.

TRADITIONAL vs IDEAL SCREW PIERS

Understanding all the costs

Below are typical steps and considerations when pouring concrete piers vs installing screw piers/piles for residential building sites and associated costs. The diagram shows the significant differences between the two approaches, but you may uncover other unknowns after you start digging.

Typical Cost Considerations

Bored Concrete Piers	Ideal Screw Piers
Digging holes Concrete pump Engineer’s inspection Additional concrete for deeper piers The addition of steel cages for deeper piers if unstable soil Sleeves in sandy soils Removing soil from site Testing Soil for ENM/VENM Potentially remove contaminated soils Hit the water table	Soil & lab testing / Lot Classification to determine required depth for fixed price peering. Installation of screw piers to correct soil profile, depth & torque as per quote.

IS MY SITE FIXABLE?

THE 4 CRITERIA

1. Idealgeotech Lot Classification Report

An Idealgeotech Lot Classification is the starting point and produces the knowledge of soil profile, reactivity and density that is used to determine the installation depth of the piers.

2. Safe working load of 85kN or less

Our modular pier rates to a safe working load of 85kN which covers the structural design of most residential homes. The modular pier design assists us in providing a fixed price.

3. Maximum pier depth of 6 metres

Our modular 85kN screw pier has a maximum installation depth of 6m and was designed for residential construction.

4. Natural or L1 compacted soil

A screw pier must be installed in natural ground or certified L1 compacted soil. This is to remove the risk of settlement.

A MODULAR SYSTEM

An excavator with rubber tracks is used to avoid damaging the pad.
Piers consist of a male & female bolted system to enable longer shafts to be easily added onsite.
No welding of extensions onsite delaying installation.
Installation log of each individual pier includes location, pier depth and torque reading.
Tops of piers are cut off to the required height as per engineers’ details.
Site pad is cleaned at the end of installation and offcuts are removed.
No waste or removal of spoil to pay for.

1. Get a Lot Classification Report

A Lot Classification is the most common geotechnical report requested for residential building sites. To find out the cost of a lot classification (Site, Soil & Wind) for your site please enter your postcode to see if your area is serviced and to purchase online.

Not sure where to start and what type of geotechnical report you need for your site? The “Geotechnical Cost Guide” is a handy resource explaining the main types of geotechnical reports used in residential construction.

Please enter a postcode to check if we service your area or determine the price and lead time. Currently, online orders support NSW, ACT & QLD postcodes only.

2. I have structural drawings. Can I fix my price?

If you’re about to make a decision regarding your slab/piers and would like to know if your site is suitable for a fixed screw piering solution, please complete the quote request form.

Even if you already have a geotechnical report along with structural drawings it’s not too late to check if your site is fixable.
