Website & General Terms of Use

Version 1.1 · Effective August 2026 · Updated September 3, 2026

These Terms of Use ("Terms") govern your use of the website www.PrietoEngineering.com (the "Site") and general inquiries made to J.F. Prieto Engineering Construction, Inc. ("JFPEC," "we," "us"). By using the Site or contacting us, you agree to these Terms. Construction services themselves are governed by our written proposals, contracts, and Standard Terms and Conditions — not by this page.

1. About JFPEC

JFPEC is a California-licensed general engineering and building contractor (CSLB License #525452, Class A and C-8) serving commercial, industrial, municipal, and private-sector clients. Our services include concrete construction and masonry; asphalt and pavement maintenance; civil grading and earthwork; underground utilities; demolition; commercial tenant improvements and general construction; ground-up general contracting and real estate development; facility maintenance; and emergency and rapid-response services.

2. No Offer; Estimates and Proposals

2.1 Content on the Site — including service descriptions, project photos, and any pricing references — is for general information only and is not an offer, quotation, or commitment to perform work.

2.2 Budgetary figures discussed by phone, email, or in preliminary conversations are good-faith estimates only. JFPEC is bound only by a written proposal signed or accepted in accordance with its terms, together with JFPEC’s Standard Terms and Conditions.

2.3 Unless stated otherwise on its face, a written JFPEC proposal is valid for thirty (30) days from its date. The latest issued version of any proposal supersedes all prior versions in their entirety.

2.4 Site visits, walkthroughs, and plan reviews performed to prepare an estimate do not create a contract and do not obligate either party to proceed.

3. Communications

3.1 The official channel for project communications and document delivery is projects@prietoengineering.com. Please direct proposals, plans, bid invitations, and contract correspondence there.

3.2 Text messages, voicemails, and conversations with field personnel are welcome for coordination, but they do not constitute notice to JFPEC and cannot change the scope, price, or schedule of any project. Direction affecting scope, price, or schedule is effective only in writing from an authorized representative.

3.3 Submitting plans or project information to us does not create a confidential or contractual relationship, though we handle client information with care and treat executed-project records as confidential business records.

3.4 We aim to respond to bid invitations and inquiries promptly during regular business hours. Emergency and rapid-response service requests should be made by phone at (800) 606-3880 ext. 1.

4. SMS Text Message Program

4.1 Program and sender. Text messages are sent by J.F. Prieto Engineering Construction, Inc. ("JFPEC") from our dedicated business number, +1 (310) 742-1360. Our main line, (800) 606-3880, is a voice line and does not receive text messages. Employees receive workforce notifications — crew schedules, jobsite start times, schedule changes, project updates, and OSHA safety notices. Clients receive project communications — appointment and site-inspection confirmations, project status updates, and replies to inquiries. Everyone who receives messages from this program, employees and clients alike, enrolls the same way, through the website form described below. This program sends informational messages only. We do not send marketing or promotional text messages, and we do not send messages on behalf of any third party.

4.2 How to opt in. There is exactly one way to join this program: the JFPEC website contact form.

Visit www.prietoengineering.com/contact and enter your mobile number. Directly below the phone field is a separate SMS consent checkbox that loads unchecked and is optional — you must tick it deliberately, and the form submits whether or not you do. The checkbox reads, in full:

"Yes, text me. By checking this box, I agree to receive recurring informational SMS text messages from J.F. Prieto Engineering Construction, Inc. (JFPEC) at the mobile number I provided - crew schedules, jobsite start times, project updates, OSHA safety notices, appointment confirmations, site inspection scheduling, and project status updates. Message frequency varies. Message and data rates may apply. Reply HELP for help or STOP to opt out. Consent is not a condition of purchase or employment. See our Privacy Policy and SMS Terms & Conditions."

Submitting the form with that box ticked records your consent, together with the date and time and the exact wording shown above. JFPEC employees who wish to receive work-related text messages enroll through this same form; participation is optional, and declining does not affect employment, assignments, pay, or standing. Employees who do not enroll continue to receive the same information by phone from their foreman and on the notice board at the jobsite office.

4.3 No other route enrolls anyone. We do not accept verbal opt-ins by phone or email, we do not enroll numbers gathered from service contracts or paperwork, we do not enroll numbers obtained from lead-generation platforms or purchased or rented lists, and consent given to another company is never treated as consent to JFPEC. Consent to receive text messages is not a condition of purchasing any goods or services, and it is not a condition of employment.

4.4 Message frequency and rates. Message frequency varies with project activity. Message and data rates may apply depending on your mobile carrier and plan. Carriers are not liable for delayed or undelivered messages.

4.5 How to opt out. Reply STOP to any message to unsubscribe at any time. STOPALL, UNSUBSCRIBE, CANCEL, END, and QUIT are also honored. You will receive one final message confirming that you have been unsubscribed, and no further texts will be sent.

4.6 How to get help. Reply HELP (or INFO) to any message for assistance, call us at (800) 606-3880, or email projects@prietoengineering.com.

4.7 Resuming messages. START and UNSTOP are not ways to join this program. If you previously opted out, replying START or UNSTOP resumes only the messages you had already consented to receive. To join in the first place, use the website contact form described in section 4.2.

4.8 Your mobile information is not shared. We do not share, sell, rent, or trade mobile phone numbers or SMS opt-in consent data with any third party or affiliate for marketing or promotional purposes. Text messaging originator opt-in data and consent are not shared with any third party. See our Privacy Policy for how we handle your information.

4.9 Eligibility and changes. You must be the account holder of the mobile number provided, or have the account holder's permission, and be 18 years of age or older. Supported carriers may change without notice. We may update these SMS terms from time to time; continued participation after changes constitutes acceptance.
