About this file

Written by GovTribe AI ·

This is a Reference Information Sheet for the State of Utah Division of Purchasing's Design Professional Services (Architecture & Engineering) Pre-Qualified Vendor List (BD27-106). The document establishes the reference submission requirements for vendors seeking pre-qualification status on an open-ended vendor list with a 12-month approval period. Vendors must submit a minimum of 5 references and a maximum of 20 references pertaining to their qualifications in design professional services. The references must include contact person information, email address, project type, and completion date, with phone number and contract amount listed as helpful but optional information. Purchasing will randomly select four references from those submitted to contact via customer satisfaction survey to evaluate vendor performance.

The scoring methodology employs a formula-based system where the average star rating from the four surveyed references is multiplied by 20 to establish a base score, which is then multiplied by a reference modifier that increases with the quantity of references provided (0.85 modifier for 5 references, 0.90 for 10 references, 0.95 for 15 references, and 1.00 for 20 references). A minimum final score of 70 points is required for qualification, with the required average star rating decreasing as more references are submitted—ranging from 4.12 stars for vendors providing only 5 references to 3.5 stars for those providing the maximum 20 references. This structure is designed to encourage vendors to provide comprehensive reference lists and discourage selective "cherry-picking" of references while rewarding extensive market experience and consistency across a larger sample size.

REFERENCE INFORMATION

Reference Sheet Instructions: Prove a minimum of (5) and a maximum of (20) references total pertaining to the categories you are pre-qualifying for. Purchasing will contact four random references (selected using an online automated “Random Number Generator,” not by hand) and send a customer satisfaction survey (found in Public Files section). If any references do not respond, Purchasing will randomly select an additional reference to contact until a response is successfully solicited from at least 4. This is another reason it is encouraged to provide as many as possible, in case any references do not respond to the survey. The 0–5-star ratings on the four surveys will be averaged to establish your potential base score, up to 100 points. Then, the number of references provided is used as a multiplier that unlocks a percentage of the base points earned. A minimum of 70 points is required to qualify to be on the Design Professional Services Pre-qualification List.

*Note: Your average star rating will be rounded to the nearest 10th decimal, rather than whole numbers, to be as fair as possible. Below, the modifiers are shown for 5, 10, 15, and 20 references provided; but the modifier increases with each single additional reference provided. You have the greatest point potential if you provide 20 references. 70 points can be achieved with a 4-star average and 8 references provided (70.4 points), or a 4.2-star average and 5 references provided (71.4 points), for example.* Formula: Average Star Rating x 20 = Base Score Base Score x Reference Modifier = Final Score

· 5 References Provided = 0.85 Modifier (85% of Base Score)

· 10 References Provided = 0.9 Modifier (90% of Base Score)

· 15 References Provided = 0.95 Modifier (95% of Base Score)

· 20 References Provided = 1.00 Modifier (100% of Base Score) Example: (4-Star Average, 5 References provided) 80 Base Points x 0.85 Modifier = 68 Final Points (4-Star Average, 20 References provided) 80 Base Points x 1.00 Modifier = 80 Final Points This is meant to encourage vendors to provide as many references as possible to prevent “cherry-picking” and to prove extensive market experience, as every single reference provided will earn more points. The only required information for each reference is Contact Person, Email Address, Project Type, & Date Completed. A phone number and dollar amount are helpful but not required.

Here is the minimum star ratings required to achieve the 70-point minimum for the 4 tiers displayed above:
