About this file
This Addendum No. 1 clarifies requirements for the Town of Herndon, Virginia's Request for Proposal (RFP 27-02) for Stormwater Management Services. The addendum addresses ten critical questions submitted by prospective offerors regarding proposal submission requirements and evaluation criteria. Key clarifications include that Appendix A (Proposal Forms) shall be included as Section 4 rather than Section 5 of proposals, projects must have been completed within the previous five years to be considered for scoring, and the submission deadline of 11:00 a.m. Eastern Standard Time on September 22, 2026, will be strictly enforced by the system. All requirements regarding page limits, formatting, font sizes, and attachments apply comprehensively to the proposal package, including forms, resumes, organizational charts, graphics, tables, and captions, with proposals limited to 60 single-sided or 30 double-sided pages total. Additionally, Attachment B regarding proprietary information must be submitted and signed by all offerors regardless of whether they have proprietary information to protect.
The addendum confirms that the current contract incumbents are Kimley-Horn & Associates, Inc. and WSP USA Environment & Infrastructure Inc. References provided by offerors should be relevant and appropriate to the services requested, with offerors responsible for determining the suitability of their submitted references. Prospective offerors must include DPOR registration numbers and names for key personnel verification, though copies of licenses are not required to be submitted. Cover letters must be included within the overall 60-page proposal limit, and all forms within Section 4 count toward the page limitation.
