Statewide Soil Testing & Engineering Services On‑Call – RFP No. 27‑05

This solicitation seeks a qualified engineering consulting firm to provide statewide soil‑testing and related engineering services on an on‑call basis for the New Mexico Department of Transportation. The contractor will perform tasks such as reviewing existing modulus‑R‑value correlations, selecting and sampling 12 subgrade sites across all NMDOT districts, conducting laboratory compaction, R‑Value, and resilient‑modulus testing, developing New Mexico‑specific correlation equations, and delivering training on the application of these results within pavement design software. The work will be performed under multiple task orders over a maximum contract term of four years. • Scope includes field sampling, laboratory testing (gradients, Atterberg limits, Proctor, R‑Value, repeated‑load triaxial) and correlation development. • Deliverables: quarterly progress reports, a final technical report with database of 12 soils, recommended NM‑specific Mr‑R‑value equations, and training materials. • Contract is funded by federal‑aid highway and state funds, with a total budget of approximately $150 K; payment is on a unit‑rate basis, subject to retainage and possible liquidated‑damage provisions.
