23 CFR § 710.309 - Design-build projects.
(a) In the case of a design-build project, ROW must be acquired and cleared in accordance with the Uniform Act and the FHWA-approved ROW manual or RAMP, as provided in § 710.201(c) and (d). The grantee shall submit a ROW certification in accordance with 23 CFR 635.309(p) when requesting FHWA's authorization. The grantee shall ensure that ROW is available prior to the start of physical construction on individual properties.
(b) The decision to advance a ROW segment to the construction stage shall not impair the safety or in any way be coercive in the context of 49 CFR 24.102(h) with respect to unacquired or occupied properties on the same or adjacent segments of project ROW.
(c) The grantee may choose not to allow construction to commence until all property is acquired and relocations have been completed; or, the grantee may permit the construction to be phased or segmented to allow ROW activities to be completed on individual properties or a group of properties, with ROW certifications done in a manner satisfactory to the grantee for each phase or segment.
(d) If the grantee elects to include ROW services within the design-builder's scope of work for the design-build contract, the following provisions must be addressed in the request for proposals document:
(1) The design-builder must submit written certification in its proposal that it will comply with the process and procedures in the FHWA-approved ROW manual or RAMP as provided in § 710.201(c) and (d).
(2) When relocation of displaced persons from their dwellings has not been completed, the grantee or design-builder shall establish a hold off zone around all occupied properties to ensure compliance with ROW procedures prior to starting construction activities in affected areas. The limits of this zone should be established by the grantee prior to the design-builder entering onto the property. There should be no construction-related activity within the hold off zone until the property is vacated. The design-builder must have written notification of vacancy from the grantee prior to entering the hold off zone.
(3) Contractors activities must be limited to those that the grantee determines do not have a material adverse impact on the quality of life of those in occupied properties that have been or will be acquired.
(e) If the grantee elects to perform all ROW services relating to the design-build contract, the provisions in § 710.307 will apply. The grantee will notify potential offerors of the status of all ROW issues in the request for proposal document.
