To Whom It May Concern:

The Montana Department of Transportation (MDT) is accepting proposals from consulting firms

interested in the preparation of the construction plans and specifications for the subject project.

One firm will be selected to perform the work specified herein.

Teams may be established as necessary; however, it is expected that the prime consultant will be

capable of completing the vast majority of the work, and the proposal must clearly identify the

prime for this contract. As a rule, the prime consultant must complete at least 50% of the work

for a specific project or assignment unless written exception is given.

Montana professional engineering licensure is required for this work and must be in-hand at the

time your proposal is submitted. If this requirement is not met and clearly identified in the

proposal, your proposal will be considered non-responsive.

If your firm is interested, please submit a proposal as described herein.

SCOPE OF WORK

The scope of work for the project includes the analysis of three (3) separate existing culverts for

rehabilitation or replacement options, followed by the design necessary to complete the selected

alternatives. Design efforts may include but are not limited to; project management, alternatives

analysis, selection of preferred alternatives, engineering and cadastral survey, hydrology and

hydraulics, floodplain analysis and permitting, geotechnical, surfacing, right-of-way, utility

impacts and conflicts, environmental permitting and documentation, roadway, full PS&E

package, and construction model development. Preliminary analysis indicates that diversion

structures and crossovers should be anticipated at all locations.

The culverts are located at the following locations;

• Bison Creek– I-15 at RP 146.08 (MDT ID 1128): 144” SSPPC (Culvert ID 228931)

• Prickly Pear Creek – I-15 at RP 179.8 (MDT ID 1165): 180” SSPPC (Culvert ID 228926)

• Dry Creek – I-90 at RP 240.7 (MDT ID 1529): 96” SSPPC (Culvert ID 181689)

As-built plans will be made available to the successful respondent.

Questions

1) Team Qualifications

Provide a discussion on how the team you propose to use for this project (including

subconsultants, if used) is best qualified to respond to the requirements of this project.

Discussion should focus on the requirements for this specific project, particularly your

team’s expertise and experience, as it relates to the work described in the “Scope of

Work” section above. Provide examples of previous related project experience as it

relates to these services. Identify professional licensure of staff that satisfy the

requirements for this contract. Include an organizational chart of your team for this

project. Also briefly discuss your compatibility of systems, software, and equipment (i.e.

CADD software, word processing software, etc.), and experience with these systems,

software, and equipment. The Department’s standard design software is Autodesk®

technology included in the Architecture, Engineering & Construction (AEC) Collection.

Describe any special equipment or software you intend to use. Resumes may be

considered as supporting documentation to verify / supplement the qualifications

described in the proposal. However, scoring will be based solely on the narrative

response included in the Team Qualifications section of the proposal.

2) Project Approach

Transportation work has many challenging aspects, and the development and delivery of

a successful project that addresses and mitigates specific project challenges is of utmost

interest to MDT. Discuss the challenges you foresee as they relate to this project and its

requirements, your strategy for addressing these challenges, and your specific experience

in implementing the strategies identified. Describe your quality assurance/quality control

process. Include a discussion on your overall plan for delivering this project in a timely

manner.

Appendix A: Resumes

Include brief resumes for the key personnel to be assigned to the contract. Resumes are

limited to one (1) page per person.

Appendix B: Cover Page Form

Include a completed version of MDT’s standard cover page form, available at the following

location:

http://www.mdt.mt.gov/other/webdata/external/cdb/MDT-CDB-002-Proposal-SOQ-Cover-Sheet.pdf

Information presented in the cover page form will not be considered in proposal scoring.

Appendix C: References

Submit references that includes a minimum of five (5) separate contracts from the past

three (3) years. If applicable, you may submit multiple contracts for a single client. Each

contract must pertain to work similar to the proposed scope of services. Include client

name, a currently employed primary contact person, an alternative contact person,

corresponding valid phone numbers and emails for both contacts, a range of contract value,

and a brief description of the work performed. If MDT needs to use these references for the

Past Performance Score (as described in the “Evaluation of Proposals” section below) and

is unable to contact the required number of references after a reasonable effort, the firm

will receive a zero for the missing reference(s).

EVALUATION OF PROPOSALS

All proposals will be evaluated in accordance with the following factors:

1) Team Qualifications (50 points possible)

2) Project Approach (100 points possible)

3) Record of past performance (30 points possible)

a) If two (2) or more MDT evaluations specific to the discipline for this contract are

available for the consultant, the average score of these evaluations will be used.

Evaluations for Project Management & Overall Performance will also be included.

b) If fewer than two (2) MDT evaluations specific to the discipline for this contract are

available for the consultant, but there are two (2) or more MDT evaluations are

available for other work disciplines, the consultant’s current overall past performance

score from MDT evaluations will be used.

c) If there is only one (1) MDT evaluation available for the consultant, the record of past

performance score will be an average of the MDT evaluation and one (1) reference

check from the references provided in the unbound attachment.

d) If no MDT evaluations are available, the average score of two (2) reference checks

from the references provided in the unbound attachment will be used for this score.

Regardless of partnership/teaming relationships, the past performance of the prime

consultant will be the past performance scored that will be used for this score.

All Proposals will be evaluated using the following basic scoring methodology:

o Outstanding/Exceptional response: 90-100% of the available points

o Good response: 70-90% of the available points

o Average response: 50-70% of the available points

o Poor response: 30-50% of the available points

o Qualifications not clearly met: 0-30% of the available points

Following the review, evaluation, and rating of all proposals, the final results will be presented to

the Consultant Selection Board (Board) at the MDT Headquarters Building. At this time, the

Board will select the most qualified firm(s) to perform the work. The Board may consider any

proposal scoring within 2% of the highest-scoring proposal as equally qualified and take into

account its knowledge of the firms’ workload, past performance, and familiarity with the project

area and local entities in selecting the most-qualified consultant. In the event that a firm cannot

be identified as the most qualified through an evaluation of these proposals, MDT reserves the

right to narrow down the list of responding firms to an appropriate short list. Short-listed firms

will either be asked to provide a supplemental proposal or asked to be interviewed or provide a

presentation. Scores from the proposals, supplement project proposals (if used), and interviews

(if used) will be carried forward to determine final consultant score. Consultant selection is

finalized by MDT at the Consultant Selection Board meeting.

INDIRECT COST RATE REQUIREMENTS

Proof of the firm’s Indirect Cost Rate (overhead rate) is not required with this proposal

submittal. However, an Indirect Cost Rate may be required prior to executing a contract

according to MDT’s Indirect Cost Rate Requirements:
