Please read this before relying on any figure Silicon Hub produces. Silicon Hub is a record-keeping and calculation tool for your own internal use. It does not provide professional advice, and you use it at your own risk.
Silicon Hub is a record-keeping and calculation tool. It is not a substitute for professional advice, and nothing it produces constitutes quantity surveying, accounting, taxation, legal, valuation, insurance or financial advice.
This applies without limitation to feasibility studies, cost estimates, unit rates, takeoff figures, budget forecasts, cashflow projections, GST summaries, progress claim schedules, staged payment percentages, loan and interest calculations, profit, margin and return figures, break-even calculations, programme and schedule dates, and warranty, maintenance-period and defects-liability dates.
You must independently verify every figure before relying on it for any contract, claim, payment, tender, funding application, tax return, statutory filing or commercial decision. Where a figure has legal or contractual consequence — including any payment claim or payment schedule under the Construction Contracts Act 2002 — you must satisfy yourself that it is correct and that any statutory timeframe has been met. Silicon Hub does not monitor, calculate or warn you about statutory deadlines.
Silicon Hub ships with default unit rates, category templates, staged payment percentages and similar reference data. These are indicative starting points only, drawn from publicly available information at a point in time. They are not quotations, valuations or professional estimates, they are not maintained as current, and they will not reflect your project, your suppliers or your market. You are responsible for reviewing them and replacing them with your own figures.
Silicon Hub calculates from the data you enter. It cannot detect an incorrect figure, a miscategorised cost, a duplicated invoice, a missing entry or an out-of-date rate. Outputs are only ever as accurate as the inputs, and you are solely responsible for the accuracy, completeness and currency of the data in your account.
Different screens in Silicon Hub deliberately measure different scopes — for example, construction cost as against whole-of-development cost — and will therefore show different totals. This is explained inside the application under Settings → How Figures Are Calculated. You are responsible for understanding which figure you are relying on.
To the maximum extent permitted by law, Silicon Hub is provided “as is” and “as available”, without warranty of any kind, whether express, implied or statutory. Silicon Homes Ltd does not warrant that the service will be uninterrupted, error-free or secure, that any calculation or output will be accurate or fit for a particular purpose, that data will not be lost or corrupted, or that third-party services it depends on will remain available.
You use Silicon Hub at your own risk.
To the maximum extent permitted by law, Silicon Homes Ltd, its directors, officers, employees and contractors are not liable for any loss, damage, cost, expense or claim of any kind arising out of or in connection with your use of, or inability to use, Silicon Hub. This includes without limitation:
This applies whether the liability arises in contract, tort (including negligence), equity, under statute or otherwise, and whether or not Silicon Homes Ltd was advised of the possibility of such loss.
Where liability cannot lawfully be excluded, the total aggregate liability of Silicon Homes Ltd for all claims arising in any twelve-month period is limited, at Silicon Homes Ltd's option, to either resupplying the service or the total subscription fees you actually paid in the twelve months immediately preceding the event giving rise to the claim. Where no fees have been paid, including during a free trial, that amount is nil.
Silicon Hub is supplied for business use only. You acknowledge that you acquire and use it in trade for the purposes of the Consumer Guarantees Act 1993 and the Fair Trading Act 1986.
You and Silicon Homes Ltd agree that the Consumer Guarantees Act 1993, and sections 9, 12A, 13 and 14(1) of the Fair Trading Act 1986, do not apply, and that it is fair and reasonable for them to be excluded, in accordance with section 43(2) of the Consumer Guarantees Act 1993 and section 5D of the Fair Trading Act 1986. You agree not to acquire Silicon Hub for personal, domestic or household use.
Nothing here excludes any liability that cannot lawfully be excluded.
You indemnify Silicon Homes Ltd against any claim, loss, liability, cost or expense (including reasonable legal costs) brought by any third party — including a client, purchaser, tenant, subcontractor, financier or regulator — arising from your use of Silicon Hub, the data you enter, any figure or document you produce from it, or your breach of these terms.
Silicon Hub relies on third-party services including Microsoft OneDrive for file storage and Stripe for payment processing. Silicon Homes Ltd is not responsible for the availability, performance, security or acts of those services, and your use of them is subject to their own terms.
Silicon Hub is under active development. Access is currently provided free of charge for a limited time, and sign-up includes a trial period of 14 days. Trial extensions may be granted on request at our discretion.
No commitment is made that Silicon Hub will remain free. We may introduce subscription charges in future, change pricing, or change what is included at any tier. Where charges are introduced for an existing account, we will give reasonable notice beforehand and you will be able to decline and export your data rather than pay.
Free or trial access does not create any entitlement to continued access, to a particular feature set, to a service level, or to any period of notice beyond the above. We may change, suspend or withdraw the service, or any part of it, at any time. Because no fee is paid during a free or trial period, the liability cap in clause 5 is nil for that period.
Silicon Hub stores your information in two places:
Because attachments reside in your own OneDrive, you retain direct access to them independently of Silicon Hub, and you are responsible for the security and configuration of that Microsoft account, including who you share those folders with. Files held in OneDrive are subject to Microsoft's terms and privacy policy in addition to ours.
We take automated, encrypted backups of Account data on a daily schedule, retained on a rolling 30-day cycle and held separately from our primary hosting environment. Backups are encrypted before they leave our server. They cover project records and user accounts; attachments are not duplicated, as they already reside permanently in your own OneDrive.
Backups are a safeguard on our side, not a guarantee. We do not warrant that any particular backup will be available or that lost data can be recovered, and you should still export your own copy from Settings → Backup & Restore. See clause 4 above.
Silicon Hub may hold personal information you enter about third parties, including purchaser names and contact details, tenant names and contact details, and vendor and subcontractor contacts. You are responsible for ensuring you have a lawful basis to collect and enter that information and for meeting your own obligations under the Privacy Act 2020 in respect of it. Silicon Homes Ltd processes it only to provide the service.
Silicon Hub — including its source code, design, interface, layout, documentation, calculation methods, templates and default rate libraries — is the property of Silicon Homes Ltd and is protected by the Copyright Act 1994 and international copyright law.
Your subscription grants you a limited, non-exclusive, non-transferable, revocable licence to use Silicon Hub for your own business purposes for as long as your subscription remains current. It does not transfer ownership of anything.
You must not copy, modify, reverse-engineer, decompile, resell, sublicence, rent or redistribute Silicon Hub or any part of it, nor use it to build a competing product, without prior written permission from Silicon Homes Ltd.
You retain ownership of the data you enter. See our Terms of Service and Privacy Policy for how that data is handled.
This disclaimer is governed by the laws of New Zealand, and the courts of New Zealand have exclusive jurisdiction over any dispute arising from it.
