The terms that govern our environmental consulting services and your use of this website.
Last Updated: August 21, 2026
CORNERSTONE CONSTRUCTION SERVICES LLC ("Company," "we," "our," or "us") provides these Terms and Conditions to govern your access to our website and environmental consulting services. By authorizing work, signing a service proposal, or using our client portals, you ("Client," "you," or "your") agree to be bound by these Terms and Conditions in their entirety. If you do not agree with any part of these terms, you must not utilize our consulting services. These terms constitute a legally binding agreement between you and the Company.
We provide professional environmental consulting and construction management services, including but not limited to Phase I and Phase II Environmental Site Assessments (ESA), soil and groundwater sampling, remediation planning, and regulatory compliance consulting. We reserve the right to halt site work if hazardous environmental conditions exceed the scope of our safety protocols or if unpermitted property boundaries are discovered.
All initial environmental service estimates and proposals provided by our firm are valid for 30 days. Initial quotes are based on preliminary site evaluations and available historical data. Final project costs may vary due to hidden subterranean conditions (e.g., undocumented underground storage tanks, buried debris) or expanded laboratory testing requirements mandated by regulatory agencies. Any major deviations from the original consulting plan must be approved through a formal, written change order before additional work proceeds.
Clients are strictly responsible for funding their environmental consulting projects according to the payment schedule outlined in their specific contract. Payment is generally due upon receipt of the final environmental report or completion of the field services, unless net terms are established in writing. The Company reserves the right to withhold final compliance reports or employ legal collection methods for any unpaid field labor, laboratory fees, or consulting services.
The Client agrees to provide our environmental professionals and drilling subcontractors with safe, unobstructed access to the property during scheduled field work hours. The Client is responsible for identifying and marking all private underground utilities (e.g., private irrigation lines, septic fields) prior to our arrival. The Company is not liable for damage to private, unmarked subterranean systems during soil boring or groundwater well installations.
While we strive to adhere to the estimated environmental assessment timeline, all project completion dates are approximate. The Company shall not be held liable for delays caused by factors beyond our reasonable control, including severe weather conditions preventing outdoor soil sampling, analytical laboratory processing backlogs, or delays in receiving historical records from municipal agencies.
Our environmental consulting services are performed in accordance with generally accepted industry standards, such as ASTM guidelines for Environmental Site Assessments. However, environmental assessments inherently involve sampling and cannot guarantee that a property is entirely free of hazardous substances. We do not provide a warranty, express or implied, regarding the absolute environmental condition of the site beyond the specific areas physically tested.
You agree to provide accurate information regarding the property, to disclose all known historical uses, previous environmental citations, and hazardous spills, and to authorize work only if you have legal authority over the site. You are responsible for notifying tenants or adjacent property owners if field testing activities will impact their daily operations.
The Company maintains comprehensive professional and general liability insurance. However, to the fullest extent permitted by law, our liability for any claim arising from our consulting services is limited to the direct cost of the specific service phase at issue. We are explicitly not responsible for pre-existing environmental contamination, resulting diminution in property value, or any indirect, incidental, consequential, or punitive damages.
If you voluntarily opt-in to receive text messages from us, you agree to receive automated SMS/MMS messages strictly for operational project management, including site inspection reminders, soil testing status updates, field crew arrival alerts, and secure invoice links. We do not use text messaging for marketing or promotional campaigns. Message frequency will vary based on the active phase of your project. Message and data rates may apply. You can opt-out at any time by replying STOP. Text HELP for assistance.
Your consent to receive these text messages is completely voluntary. The SMS opt-in checkbox on our service inquiry forms is explicitly not mandatory. Opting out will not affect your ability to contract with us for your environmental consulting projects. We do not share, sell, rent, or trade your mobile phone data with any third parties, external analytical laboratories, or subcontractors for marketing purposes.
All environmental compliance reports, CAD site plans, remediation blueprints, and custom data analyses created or provided by CORNERSTONE CONSTRUCTION SERVICES LLC remain the exclusive intellectual property of the Company. These materials are provided solely for the execution of your specific project and may not be reproduced, distributed, or utilized by third parties without our express written permission.
These Terms and Conditions and all consulting contracts shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, without regard to its conflict of law principles. Any legal disputes arising from our environmental consulting services must be resolved through good faith negotiation. If litigation becomes necessary, both parties consent to the exclusive jurisdiction of the state courts located in Middlesex County, Massachusetts.
You agree to fully indemnify and hold harmless CORNERSTONE CONSTRUCTION SERVICES LLC, its officers, environmental scientists, and staff from any claims, damages, or liabilities arising from your intentional failure to disclose known property hazards or severe contamination. If any provision of these Terms is found by a court to be unenforceable, that specific provision shall be limited to the minimum extent necessary so that the remainder of these Terms shall remain in full legal effect.
