Construction Support
Engineering support during construction: RFIs, revisions, field changes and close-out.
Construction rarely goes exactly as drawn. TDR stays engaged through construction to answer RFIs, prepare revisions, resolve field conflicts and support agency close-out.
Because TDR also performs the survey and as-built work, field questions can usually be resolved with measured data rather than assumption.
