1. Professional Judgment Required
IESE is an estimating aid, not a substitute for professional estimating practice. The user remains solely responsible for the accuracy and suitability of every estimate produced with the Software, including verification of quantities, scope, labor rates, equipment and material pricing, site conditions, productivity assumptions, and the final bid amount.
The manhour database and other values supplied with the Software are reference starting points reflecting the author's experience. They are not guarantees of field production on any particular project. Users are expected to apply proper estimating techniques and procedures — including independent takeoff verification, site-specific adjustment, peer review, and management approval — before relying on any output for a bid, proposal, budget, or contractual commitment.
2. No Warranty
The Software is provided "AS IS" and "AS AVAILABLE," without warranty of any kind, express or implied, including but not limited to warranties of accuracy, completeness, reliability, merchantability, fitness for a particular purpose, or non-infringement. No oral or written information provided by the author shall create any warranty. The author does not warrant that the Software will be error-free or uninterrupted.
3. Limitation of Liability
To the maximum extent permitted by law, the author shall not be liable for any direct, indirect, incidental, special, consequential, or exemplary damages arising from or related to the use of, or inability to use, the Software — including but not limited to lost profits, lost bids, bid errors or omissions, cost overruns, business interruption, or loss of data — even if advised of the possibility of such damages. You assume full responsibility for all decisions made and actions taken based on the Software's output.
4. Not Professional Advice
Output from the Software does not constitute engineering, financial, legal, or professional estimating services, and no professional relationship is created by its use. Where professional certification, sealing, or review of an estimate is required, that remains the user's obligation.
5. License Terms
- Single Seat license: licensed to one named estimator for use on that estimator's machines. Not transferable between individuals without written consent.
- Company license: licensed to one company for use by its estimating personnel at that company.
- The Software, including its manhour database, structure, and reports, is proprietary to the author. Patent Pending.
- You may not redistribute, resell, sublicense, rent, or publicly post the Software or any portion of it.
- You may not reverse engineer, decompile, or extract the manhour database for use outside the Software or for incorporation into any other product or service.
- Custom items and rates you add to your copy remain yours.
6. Demo Version
The free demo is provided for evaluation only, for the stated trial period, and includes a restricted sample of the manhour database. Demo output is for evaluation and must not be used as the basis for a commercial bid or contractual commitment. The demo may not be redistributed, and the trial mechanism may not be circumvented or reset.
7. Updates and/or Support
Updates and/or support are provided as described at the time of purchase, or under an optional annual maintenance arrangement where offered. The author has no obligation to provide perpetual updates, enhancements, or support beyond what is expressly included with your license or maintenance term. Purchased licenses do not expire.
8. General
If any provision of these terms is held unenforceable, the remaining provisions remain in full effect. These terms constitute the entire agreement regarding use of the Software and supersede prior communications on the subject. The author may update these terms for future versions; the terms in effect at the time of your purchase govern your license.
