22 CAR § 111-209 – Geotechnical engineering services fees

(a) Geotechnical investigations are considered a specialized engineering service and fees for geotechnical services may be negotiated on an hourly, not-to-exceed rate, or a lump-sum agreement.
(b) If conditions are such that a lump sum (not to exceed) cannot be guaranteed, then a unit price per boring or trench may be included to cover the suspected conditions that may be encountered.
(c) Fees for this type of service require the approval of the Design Review Section.
(d) Prior to finalizing the negotiations, submit a draft of the scope of the work and the proposed fee arrangement to the Design Review Section.
