UTILITY INVESTIGATION STATEMENT OF ASCE 38-22 COMPLIANCE

THE UTILITIES DEPICTED HAVE BEEN INVESTIGATED IN GENERAL ACCORDANCE WITH

THE ASCE 38-22, "STANDARD GUIDELINE FOR INVESTIGATING AND DOCUMENTING

EXISTING UTILITIES ," STANDARD AND SHOWN AT THEIR ACHIEVED QUALITY LEVELS.

ALL OTHER INFORMATION HAS BEEN PROVIDED BY OTHERS AND INCLUDED AS

REFERENCE ONLY.

TELEPHONE CABINETCAB

OVERHEAD FIBER OPTIC LINE (OWNER AS NOTED) (QUALITY LEVEL IS AS NOTED)

1. SUBSURFACE UTILITY ENGINEERING IS A PROFESSIONAL PRACTICE DEFINED BY THE AMERICAN SOCIETY OF CIVIL ENGINEERS (ASCE.) T2 UES, INC. CONDUCTS UTILITY INVESTIGATIONS IN

ACCORDANCE WITH ASCE 38-22: STANDARD GUIDELINE FOR INVESTIGATING AND

DOCUMENTING EXISTING UTILITIES. IDENTIFYING AND DOCUMENTING UNDERGROUND UTILITIES

IS A RESULT OF GATHERING EVIDENCE FROM VARIOUS SOURCES, AND EXACT UTILITY

LOCATIONS ARE NOT CONFIRMED UNLESS VISUALLY EXPOSED AND SURVEYED, AND THEN

ONLY AT THOSE SPECIFIC EXPOSED LOCATIONS. ADDITIONALLY, T2 UES, INC. CANNOT

GUARANTEE THAT ALL UTILITIES HAVE BEEN DISCOVERED AND DEPICTED.

2. IN ACCORDANCE WITH 2018 COLORADO REVISED STATUTES, TITLE 9, ARTICLE 1.5 T2 UES, INC.

SUBMITTED A SUBSURFACE UTILITY ENGINEERING NOTIFICATION TO THE COLORADO 811

ASSOCIATION ON 6/27/2024.

3. T2 UES, INC. INVESTIGATED ALL UTILITIES INCLUDED WITHIN THE SCOPE OF WORK INSIDE THE

PROJECT LIMITS. THOSE UTILITIES ARE DEPICTED AS INDICATED IN THE LEGEND. OTHERS

PROVIDED ALL OTHER INFORMATION, NOTABLY THE BACKGROUND INFORMATION, AND T2 UES,

INC. DISCLAIMS RESPONSIBILITY FOR ITS ACCURACY.

4. INVESTIGATIONS OF DEPICTED UTILITIES WERE COMPLETED ON 8/28/2024. A SECOND FIELD

INVESTIGATION WITH EXPANDED PROJECT LIMITS WAS COMPLETED ON 2/20/2025 THROUGH

3/6/2025. T2 UES, INC. DISCLAIMS RESPONSIBILITY FOR NEW INSTALLATIONS OR ALTERATIONS

TO EXISTING UTILITIES AFTER THIS DATE. CONSIDERATION SHOULD BE GIVEN TO UPDATING

THIS INVESTIGATION BEFORE THE FINAL DESIGN AND/OR CONSTRUCTION.

5. UTILITY SIZE AND MATERIAL ARE SHOWN IF AVAILABLE FROM RECORD INFORMATION.

ADDITIONALLY, FIELD OBSERVATIONS WERE CONDUCTED, WHERE POSSIBLE, TO

CORROBORATE AND SUPPLEMENT RECORD INFORMATION, BUT T2 UES, INC. DOES NOT

GUARANTEE ITS ACCURACY OR COMPLETENESS. PIPE DIAMETERS ARE NOMINAL AND NOT

EXACT UNLESS OTHERWISE NOTED.

6. PROFESSIONAL ASSISTANCE BY T2 UES, INC. IS RECOMMENDED IN SELECTING LOCATIONS FOR

QUALITY LEVEL A DATA FOR SPECIFIC DESIGN DECISIONS.

7. THIS INVESTIGATION DEPICTS UTILITIES FOR PLANNING AND DESIGN PURPOSES BUT NOT FOR

CONSTRUCTION. FOR DAMAGE PREVENTION DURING CONSTRUCTION, COMPLY WITH

APPLICABLE ONE-CALL LAWS (CONTACT 811).

8. THESE PLANS HAVE BEEN PREPARED FOR THE USE OF T2 UES, INC.'S CLIENT AND MAY NOT BE USED, REPRODUCED, OR RELIED UPON BY THIRD PARTIES EXCEPT AS AGREED BY T2 UES, INC.

AND ITS CLIENT OR AS REQUIRED BY LAW.

9. AS DEFINED BY THE PROJECT SCOPE, T2 UES, INC. ATTEMPTED TO FIND UNDOCUMENTED

UTILITIES. DEPICTED AND LABELED AS UNKNOWN UTILITIES ON THE PLAN SET, AS THEY HAVE

NO CORRELATED RECORDS OR VISIBLE APPURTENANCES TO DETERMINE FUNCTION OR TYPE.

HOWEVER, UNDOCUMENTED UTILITIES MAY BE PRESENT IN THE PROJECT AREA THAT WERE

NOT DISCOVERABLE BY THE SCOPED EFFORT AND ARE THEREFORE NOT DEPICTED.

10. AS PER THE PROJECT SCOPE, THE POSITIONING AND SIZE OF SUBSURFACE UTILITY VAULTS WERE NOT INCLUDED AS PART OF THIS INVESTIGATION. IF FOUND TO BE IN CONFLICT WITH THE

PROPOSED PLANS, THE POSITIONING AND SIZE OF THE VAULTS SHOULD BE CONFIRMED.

11. UNDER THE PROJECT SCOPE, THE FOLLOWING UTILITIES WERE EXPRESSLY EXCLUDED FROM THIS INVESTIGATION: LANDSCAPE IRRIGATION SYSTEMS, TRAFFIC LOOP DETECTION DEVICES, CATHODIC PROTECTION SYSTEMS AND THEIR APPURTENCES, SEWER LATERALS, AND

UNDERGROUND STORAGE TANKS / ASSOCIATED PIPING OR SEPTIC SYSTEMS.

12. UTILITIES ARE GENERALLY DEPICTED BY A SINGLE LINE. HOWEVER, LARGER UTILITIES (12" AND

GREATER) MAY BE DEPICTED AT THEIR REPORTED WIDTH, CENTERED OVER THE ACTUAL

QUALITY LEVEL RESULTS. THEREFORE, ANY UTILITY EDGES SHOWN ARE FOR SCHEMATIC

DEPICTION ONLY AND SHOULD NOT BE CONSIDERED RELIABLE FOR DESIGN. IF EXACT EDGES

OF UTILITY ARE NEEDED, QLA DATA IS REQUIRED.

13. NON-CONDUCTIVE UTILITY PIPES, WHERE TRACER WIRE IS AVAILABLE, ARE DESIGNATED AND

LABELED QLB. HOWEVER, DUE TO THE UNKNOWN WIRE INSTALLATION MEANS AND METHODS

DURING CONSTRUCTION, THE ALIGNMENT LOCATION OF THE TRACER WIRE MAY BE DIFFERENT

FROM THE ALIGNMENT LOCATION OF THE ACTUAL UTILITY PIPE. TYPE AND QUANTITY OF

NON-CONDUCTIVE PIPE MAY ALSO NOT BE ACCURATELY REFLECTED DUE TO THE NATURE OF

GEOPHYSICS.

14. OVERHEAD UTILITIES ARE NOT ASSIGNED A QUALITY LEVEL UNLESS OTHERWISE NOTED.

15. SUE INVESTIGATION MAY HAVE OCCURRED WHILE SNOW COVER IS PRESENT. BEST EFFORTS

WERE MADE TO ACCURATELY DEPICT FACILITIES AS THEY EXIST AT THE TIME OF

INVESTIGATION, GIVEN THE FIELD CONDITIONS ENCOUNTERED. HOWEVER, FEATURES SUCH AS

CULVERTS MAY BE COVERED BY SNOW AND INADVERTENTLY MISSED, ESPECIALLY IN CASES

WHERE RECORDS ARE NOT AVAILABLE.

16. T2 UES, INC. PERFORMED QLA TEST HOLES FROM 6/9/2025 TO 6/11/2025. THE INFORMATION

GATHERED FROM THE QLA TEST HOLES HAS BEEN INCORPORATED INTO THESE PLANS.
