INTRODUCTION

Boxelder Sanitation District (District) through this Request for Qualifications (RFQ) is seeking Letters of Interest and Statements of Qualifications (SOQs) from General Contracting firms with demonstrated experience and success in the construction of wastewater treatment plants, who are willing to work as a team member with District staff and its Design Engineer to design and construct an upgrade to its existing wastewater treatment plant (Project).

The District intends to prequalify a selected group of General Contractors who will be invited to submit proposals to provide design assistance (e.g., constructability consultation) and construction of the Project as further described herein.

Notwithstanding anything to the contrary herein, the District has no obligation to make a selection of prequalified contractors based on this RFQ and may terminate the selection process at any time. The District retains the discretion to modify, expand or delete any portion of the Project outlined in this RFQ. The District reserves the right to reject any or all of the responses to this RFQ without cause and accept any response that, in the District’s sole judgment, will be in the best interest of the District. The District assumes no responsibility for payment of any expenses incurred by a respondent to this RFQ.

PROJECT OVERVIEW:

The Project consists of upgrading the existing District WWTP scum collection system and the installation of a recuperative thickening system. The Project will occur at the existing District plant site located approximately one mile south and west of the intersection of Interstate 25 and Prospect Road near Ft. Collins, Colorado.

The District hired Carollo Engineers as the Design Engineer for the project and has currently completed the preliminary design phase.

PROJECT DESCRIPTION:

The general and conceptual description of the major facilities required for the Project include:

1. Scum Collection System: Demo and replace existing collection manhole structures with prebuilt pump stations. Effluent from prebuilt structures will be routed through existing gravity system via pressurized line.

2. Recuperative Thickening: Installation of recuperative thickener. Includes upgrades to polymer feed, potable water lines, and non-potable water lines.

Included in the documents are conceptual drawings showing the proposed improvements. The drawings are found in the Appendix and include Predesign Drawings. These drawings are of conceptual nature and are only intended to provide the proposers with general information about the scope of the project.

April 21, 2025

OWNER INFORMATION:

The Boxelder Sanitation District is a statutory special district and political subdivision of the State of Colorado. Its sole function is to provide sanitary sewer service to customers within lands included in the District. It currently serves approximately 19,500 residents in Ft. Collins, Timnath and surrounding properties within Larimer County.

PROJECT APPROACH:

The District plans to implement the Project using the Construction Manager at Risk (CM@R) method of delivery. The selected General Contractor will participate in this collaborative, team-based delivery of the Project. The team will include the Owner, the Design Engineer, the General Contractor and major equipment suppliers, regulators, and specialty consultants as needed.

The phases of the Project as envisioned are:

A. Design & Construction Phase

1. Preliminary Design Engineering (30% design)

2. Select General Contractor

3. Final Design (with Owner, Design Engineer, Contractor and Consultant(s) working collaboratively to complete design)

a. Construction Guaranteed Maximum Price (GMP) contracting anticipated to be used installation of all work on the project B. Start-Up Phase

C. Post-Construction Phase The General Contractor will be selected as soon as possible and no later than at the completion of the 60% design phase. The selected General Contractor shall provide design phase pre-construction services, including but not limited to: cost estimating, scheduling, constructability reviews, and value engineering. The District will negotiate compensation for these services with the General Contractor.

The goal of the District is to contract with the selected General Contractor for the construction of the designed Project, using a Guaranteed Maximum Price (GMP) for the project, sometime prior to final completion of the design. Should the selected General Contractor and the District not achieve agreement on a GMP construction contract the District may then seek other General Contractors or revise the construction-phase scope of work at that time.

PROJECT (MILESTONE) SCHEDULE:

The Project schedule has been completed for the preliminary design phase (up through 30% design) at this time. Selection of the Contractor and start of construction dates will be finalized as the design progresses. Listed below are anticipated Project milestone dates which should aid Respondents in planning their efforts accordingly.
