SUBSURFACE UTILITY ENGINEERING QUALITY LEVELS PER ASCE 38-02*

· QUALITY LEVEL D: QLD IS THE MOST BASIC LEVEL OF INFORMATION FOR UTILITY LOCATIONS.

IT COMES SOLELY FROM EXISTING UTILITY RECORDS OR VERBAL RECOLLECTIONS, BOTH

TYPICALLY UNRELIABLE SOURCES. IT MAY PROVIDE AN OVERALL "FEEL" FOR THE

CONGESTION OF UTILITIES, BUT IS OFTEN HIGHLY LIMITED IN TERMS OF

COMPREHENSIVENESS AND ACCURACY. QL-D IS USEFUL PRIMARILY FOR PROJECT PLANNING

AND ROUTE SELECTION ACTIVITIES.

· QUALITY LEVEL C: QLC IS PROBABLY THE MOST COMMONLY USED LEVEL OF INFORMATION. IT

INVOLVES SURVEYING VISIBLE UTILITY FACILITIES (E.G., MANHOLES, VALVE BOXES, ETC.) AND

CORRELATING THIS INFORMATION WITH EXISTING UTILITY RECORDS (QL-D INFORMATION).

WHEN USING THIS INFORMATION, IT IS NOT UNUSUAL TO FIND THAT MANY UNDERGROUND

UTILITIES HAVE BEEN EITHER OMITTED OR ERRONEOUSLY PLOTTED. ITS USEFULNESS,

THEREFORE, IS PRIMARILY ON RURAL PROJECTS WHERE UTILITIES ARE NOT PREVALENT, OR

ARE NOT TOO EXPENSIVE TO REPAIR OR RELOCATE.

· QUALITY LEVEL B: QLB INVOLVES THE APPLICATION OF APPROPRIATE SURFACE GEOPHYSICAL

METHODS TO DETERMINE THE EXISTENCE AND HORIZONTAL POSITION OF VIRTUALLY ALL

UTILITIES WITHIN THE PROJECT LIMITS. THIS ACTIVITY IS CALLED "DESIGNATING". THE

INFORMATION OBTAINED IN THIS MANNER IS SURVEYED TO PROJECT CONTROL. IT

ADDRESSES PROBLEMS CAUSED BY INACCURATE UTILITY RECORDS, ABANDONED OR

UNRECORDED FACILITIES, AND LOST REFERENCES. THE PROPER SELECTION AND

APPLICATION OF SURFACE GEOPHYSICAL TECHNIQUES FOR ACHIEVING QLB DATA IS CRITICAL.

INFORMATION PROVIDED BY QLB CAN ENABLE THE ACCOMPLISHMENT OF PRELIMINARY

ENGINEERING GOALS. DECISIONS REGARDING LOCATION OF STORM DRAINAGE SYSTEMS,

FOOTERS, FOUNDATIONS AND OTHER DESIGN FEATURES CAN BE MADE TO SUCCESSFULLY

AVOID CONFLICTS WITH EXISTING UTILITIES. SLIGHT ADJUSTMENTS IN DESIGN CAN PRODUCE

SUBSTANTIAL COST SAVINGS BY ELIMINATING UTILITY RELOCATIONS.

· QUALITY LEVEL A: QLA, ALSO KNOWN AS "LOCATING", IS THE HIGHEST LEVEL OF ACCURACY

PRESENTLY AVAILABLE AND INVOLVES THE FULL USE OF THE SUBSURFACE UTILITY

ENGINEERING SERVICES. IT PROVIDES INFORMATION FOR THE PRECISE PLAN AND PROFILE

MAPPING OF UNDERGROUND UTILITIES THROUGH THE NONDESTRUCTIVE EXPOSURE OF

UNDERGROUND UTILITIES, AND ALSO PROVIDES THE TYPE, SIZE, CONDITION, MATERIAL AND

OTHER CHARACTERISTICS OF UNDERGROUND FEATURES.

STRUCTURAL PRACTICES

THE PURPOSE OF THIS PROJECT IS TO CONSTRUCT A NEW VISITOR'S

CENTER FOR THE NATIONAL GUARD'S ARMY READINESS CENTER. THE

PROJECT IS LOCATED AT 111 SOUTH GEORGE MASON DRIVE,

ARLINGTON, VA 22204.

DISTURBED SITE AREA: 0.2283 ACRES (VISITOR'S CENTER)

THE EXISTING SITE CONSISTS OF A SMALL GRASSED AREA NEXT TO A

PARKING GARAGE WITH AN ASPHALT PATH RUNNING THROUGH IT IN

ADDITION TO LANDSCAPING. THE SITE FOR THE VISITORS CENTER WILL

BE IMPROVED BY CONSTRUCTING THE NEW BUILDING AND

REMOVING/REPAIRING SECTIONS OF SIDEWALK.

THE SITE IS LOCATED AT 111 SOUTH GEORGE MASON DRIVE, AT THE

ENTRANCE TO THE NATIONAL GUARD COMPOUND ON A STRIP OF LAND

BETWEEN THE PARKING GARAGE AND ENTRANCE ON A FLAT GRASS

COVERED YARD.

ON-SITE SOILS FOR THE AREA ARE WELL DRAINED WITH GRADUAL

SLOPES. ALL AREAS OF WORK FOR THE VISITOR'S CENTER OCCUR ON

IMPERVIOUS AREAS OF THE EXISTING SITE.

OFF-SITE AREAS DESCRIPTION

NO OFF-SITE AREAS ARE TO BE UTILIZED FOR THIS PROJECT.

EARLY ESTABLISHMENT AND PROPER MAINTENANCE OF PERIMETER

CONTROLS WILL PROVIDE SEDIMENTATION CONTROL. STABILIZE AND

MAINTAIN DITCHES AND FILL SLOPES THROUGH ALL CONSTRUCTION

PHASES TO CONTROL ANY EROSION ON-SITE. SLOPE IN FRONT OF

AND AROUND THE VISITORS CENTER IS CRITICAL. THESE SLOPES ARE

BETWEEN 4% AND 7%.

UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL

EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE

CONSTRUCTED AND MAINTAINED IN ACCORDANCE WITH THE MINIMUM
