Frequently Asked Questions

  • Why is an encroachment permit required for main sewer tie-ins and street plumbing?

    Cutting into streets or sidewalks for utility tie-ins directly impacts public right-of-ways, requiring a municipality-approval, ofter requiring a Traffic Control Plan. We take the headaches out of complying with municipal red tape associated with traffic planning, so your main line repair stays on budget.

  • How does 123TCP help plumbing contractors avoid project downtime?

    When a city inspector shuts down a trench or tie-in due to missing paperwork, every hour counts. 123TCP offers fast-track drafting through our direct online platform, bypassing traditional delay-ridden brokerages.

  • Why is 123TCP better than hiring local traffic contracting companies?

    Local traffic control vendors are often delay-ridden contractors focused on selling flagging services and gear rentals instead of drafting quality plans FAST. 123TCP gives you exactly what you need—compliant, expedited TCP drafting—with zero unnecessary upsells.

  • What should I provide when requesting a sewer tie-in traffic control plan?

    Provide the trench or excavation location by drawing the work area you need in our portal along with other job details, and our drafters will handle the engineering layout to meet local standards.

  • What if I need a plan updated due to city reviewer comments?

    Our drafters design plans adhering to strict MUTCD and municipal standards to minimize revisions. Even then, it is common for each approving engineer to make special requests. This is why 123TCP offers a free redline revision within the first month for every plan.*

    *The free revision cannot change the original scope of work. Any scope changes are processed separately as change orders.
