Why is sue important?
John Campbell,P,E, director of the Right of way Division at TxDOT and chair of the American association of state highway and transportation Officials ’(AASHTO) subcommittee on Right-of-way and utilities, initiated the SUE program in Texas. The SUE process, provides valuable engineering information from which to make risk-based decisions …for the delivery of transportation projects, Czmpbell says AtTxDOT, the use of SUE in project planning and design enables us to avoid unnecessary impacts to existing utilities and to save the incalculable costs of adjustments ” that were not required because the SUE process located the utilities beforehand and construction delays never occurred.
An FHW A guidebook, program guide: Utility relocation and Accommodadation on Federal-Aid Highway projecys(FHWA-IF-03-014),states that the proper use of this cost-effective professional engineering service will eliminate many of the utility problems typically encountered on highway projects. According to the guide ,problems reduced or eliminated include project delays caused by (1)waiting for utility relocations to be completed, so highway construction can begin ; and(2) redesign when construction cannot follow the original design due to unexpected utility conflicts Other problems avoided include (3)delays to contractors during highway construction caused by cutting, damaging , or discovering utility lines that were not
known to be present;(4)claims by constractors to project owners for delays resulting from unexpected encounters with utilities; and(5) deaths, injuries, property damage, and releases of product(such sa natural gas or wasterwater) into the envieonment caused by damaging utility lines that were not known to be there .
Jeffery Zaharewicz, FHW A value engineering/utilities program manager ,describes SUE as”one of the best tools available to successfully integrate the activities associated with utility relocation and coordination into the project development process.”
SUE SUCCESS STORIES
A sampling of successful outcomes that resulted from the use of SUE further demonstrates the benefits of this process
When widening I-75,the Georgia Department of Transportation(GDOT) planned to relocate existing water and sewer mains that led from a rest area to a source several miles away. After obtaining and analyzing SUE data, however, GDOT determined that no conflicts were present, and therefore relocating the lines would be unnecessary. This decision conservatively saved GDOT at least $400,000.
In Texas,he use of SUE data enabled consultants working for TxDOT to design around several high-pressure pipelines crossing a major State highway,S-130.To achieve this outcome, the designers shifted the schematic right-of-way approximately 300 feet(91 meters),avoiding
costly pipeline relocations. The right-of-way shift prevented project delays and resulted in accost savings of $3 million.
Hurricane Wilma damaged an estimated 10,000 trees in Coral Springs, FL, that therefore needed to be removed. Wishing to be proactive and prevent costly utility damage, the city hired an SUE provider to locate utilizes ahead of the tree removal crews. During the first week, SUE prevented sevsral major utility hits. Due to the quantity of utility lines found by the provider, the city changed its approach and decided to grind many tree trunks instead of going ahead with complete stump removal. In one area ,where SUE was not used, the tree removal crews hit a major water line on the first day.
The Early Days of SUE
The value of SUE became apparent to highway engineers when an engineering company in Manassas Park, V A, introduced the practice in 1982.The company combined two relatively new technologies- surface geophysics and air/vacuum excavation-to gather data on the exact location of subsurface utilities early in the development of projects.
One year later, the transportation department in nearby Fairfax County,V A,beame the first government agency to use SUE on highway projects. In 1985 the Virginia Department of Transportation(VDOT) became the first State agency to use it.
“We discovered many years ago that the old ways of obtaining
utilities information for design purposes were not working, ” says Greg Wroniewicz, VDOT utility engineer. SUE does work, and we use it on nearly every highway project.
FHW A began promoting SUE in 1991,shortly after its nationwide potential was recognized by Jim Overton, now retired but then-acting branch chief,and Jerry Poston,now deceased but then-branch chief, of FHW ’s former Railroads, Uilities, and Ptograms Branch. Poston was often heard to say that SUE would revolutionize the way utilities are handled on highway projects.
“His prophecy certainly came true, ” says Jon Obenberger, FHW A preconstruction group team leader. Reliable subsurface utility data now can be provided to highway designers, and it is no longer acceptable practice to design highways or construct projects without consideration of those data.
How Has SUE Evolved?
By the 1990s,the new approach had spread from Virginia into nearby States(Delaware, Maryland, North Carolina, and Pennsylvania) and then to more distant States(Arizona and Florida).As the practice of SUE spread, it evolved to include surveying, CADD, affixing of a professional engineer ’s seal to deliverables, and professional liability insurance.
SUE flourished in the 1990s as more States began using it, and more providers began to emerge. Probably the most significant advance in that
decade involved the introduction of the concept of the quality levels, which enabled designers to certify on project plans a certain level of comprehensiveness and accuracy for the utility information.
By the end of the 1990s,however,some confusion still existed as to just exactly what SUE was. Some companies were claiming that SUE meant subsurface utility exploration or ”pot-holing, ” rather than subsurface utility engineering. The latter provides more accurate and comprehensive information than can be obtained by randomly digging pot-holes. Some DOTs bought into the former concept with poor results that soured them on continuing the use of SUE.
The leading providers were aware that SUE was an engineering practice with quality levels and were promoting it as such .FHWA also recognized the distinction between an engineering practice and pot-holing and began strongly encouraging State DOTs to acquire the service of reputable SUE providers.
The need to quantify the value of SUE on highway projects had become apparent, as well as the need to establish standard guidelines for its use 。FHW A commissioned Purdue University to document and quantify SUE ’S value ，and the American Society of Civil Engineers （ASCE ），working with FHW A and industry ，agreed to establish national guidelines for collecting and depicting existing subsurface utility data 。
Research on the effectiveness of SUE
Purdue university published its report ，cost savings on high way projects utilizing subsurface Utility Engineering ，in 2000 。the Purdue researchers studied 71 projects in North Carolina，Ohio ，Texax ，and Virginia 。The projects involved a mix of interstate ，arterial ，and collector roads in urban ，suburban ， and rural settings。
Two broad categories of savings emerged—quantifiable and qualitative savings 。The Purdue study quantified a total of $ 4.62 in avoided costs for every $ 1.00 spent on SUE 。 The greatest savings came from avoiding utility relocations and reducing delay claims。 Although qualitative savings （for example ，avoided impacts on nearby homes and business ）were not measurble ，the researchers believed those savings were significant and possibly many times more valuable than the quantifiable savings。
The study conclueded that SUE is a viable technological practice that reduces project costs related to subsurface Utilities and that DOTs should use it in a systematic manner。 In addition ，the Ontario sewer and water main contractors association commissioned the university of Toronto to investigate the practice of using SUE on large infrastructure projects in Ontario 。this study chose nine case studies and determined that the average rate of return for
each dollar spend on SUE, revices on those projects was $3.41。 the study also made a number of qualitative recommendations regarding the use of SUE .
研究报告称地下工程实用是有关减少地下工程项目费用的可实行技术实践。州交通部应该以系统的方式加以使用。
另外，安大略下水道和总水管承包商协会委任多伦多大学调查在安大略大型基础设施项目中对地下工程实用的实际应用。这项研究选择了九个专题，并且确定项目应用地下工程实用后，每投入$3.41平均回报率为一美元。 研究也提出了一定数量的定性建议关于对地下工程实用的用途。
The asce standard
In 2003，ASCE defined SUE as an engineering practice in CI/ASCE 38-02，standard guideline for the collection and depiction of existing subsurface utility data 。The importance of this standard is that it indicated that，in addition to FHWA，a prominent national engineering organization defined SUE as an acceptable engineering practice and provided guidance for applying it on projects。
2003年， 美国土木工程师学会在CI/ASCE 38-02以工程学实践定义了地下工程实用，为汇集和描述现有地下下公用设备的标准指南。这个标准的重要性是它表明了，除联邦公路管理局之外，一个享誉全国的工程学组织也将地下工程实用定义为可接受的工程学实践和施工
指南。
The standard presents the system of classifying the quality level of sub face utility data。The classification enables project owners ，engineers ，and construction companies to develop strategies to reduce risks related to existing subsurface utilities or ，at a minimum ，to allocate the risks in a defined manner。 The standard closely follows concepts already in place in the USE profession 。 Many state Dots therefore are already in compliance with the standard through their use of SUE or through their inclusion of SUE specifications in their engineering contracts。
标准提出分类地下公用设备数据的质量水平系统。分类使业主、工程师和建筑公司在地下工程的开发战略中减少风险，或者用被定义为极小值方法来分配风险。 此标准与实际地下实用工程领域接轨。 因此许多州交通部已经依从标准通过对地下工程实用的应用，或通过在工程合同中对地下工程实用的规格。
The private sector and FHWA roles
The growth of SUE resulted from efforts by FHWA's headquarters and division offices to encourage state DOTs to use it and from state DOTs officials telling their counterparts about it 。but some of credit also must go to SUE professionals who understood the process and worked to sell the concept to
potential clients 。
地下工程实用的广泛应用要归功于联邦公路管理局的总部和分区办公室鼓励各州交通部对其使用以及各州官员对相应各个部门的宣传。但也必须为那些懂得如何使用地下工程实用和以及那些专门挖掘潜在客户的其销售商记功。
FHWA encouraged the use of SUE through memos to field offices 。Also ，division administrators and their staff engineers discussed SUE with their state DOT counterparts and encouraged them to give it a try 。FHAW developed flyers，brochures ，and handbooks and distributed them to the divisions and state DOT offices ；wrote numerous papers for conferences and publications，set aside funds for SUE-related research projects ；delivered presentations at conferences and workshops at approximately 20 state DOTs and other venues ；obtained funds to develop and / or distribute instructional videos ；and funded demonstration projects in Oregon ，Puerto Rico ，and Wyoming。
联邦公路管理局通过备忘方式鼓励工程行业部门对其应用。并且，分区官员和他们的人员技师与各州交通部做了商议并且鼓励他们试用地下工程实用。联邦公路管理局制定了传单、小册和手册将其分发给了各个分区办公室; 编写会议文稿，出版物，并且为地下工程实用相关的研究计划留出了资金; 在20多个州交通部和其他地点开展会

updated to include conflict analysis ,which is the newest
engineering practice to evolve from SUE .SUE continues to be the subject of many presentations and workshops at conferences such as the annual conference of the AASHTO Right-of-Way and Utilities subcommittee, the transportation research board annual meeting ，and others。
另外，澳洲标准协会与美国土木工程学会一起使用开发工程学标准相似于ASCE 38-02预期成长为地下工程实用。而最近此项科学实践又被介绍到了比利时、中国、新西兰和阿拉伯联合酋长等国家。 地下工程实用是 国家/基础工程 /问题 (FHWA-NHI-134006)的整体部分。当前正在更新，包括冲突分析，是从地下工程实用中演变出的最新工程学惯例。地下工程实用仍然是许多会议的热门话题，比如AASHTO 基础建设小组委员会年会，运输研究委员会年会和其他一些会议。
Today ，utilities should no longer be unnecessarily relocated or unexpectedly encountered on highway projects 。 The application of SUE by transportation agencies and qualified providers who understand the practice makes it possible to avoid utility related problems that have plagued highway engineers for decades and thereby accelerate project delivery 。
C. Paul Scott ，P.E., has been Cardno TBE's national utilities liaison since 2003，joining it after retiring from FHWA ,where he worked for 34 years 。He received the university
of Tennessee and is a registered professional engineer in Kentucky and Virginia。
今天，在高速公路项目应该不会有多余地调迁或意想不到地下工程问题。 地下工程实用的实用者是交运机构和具有资格的并懂得如何避免已困扰了公路工程师数十年的公共问题从而加速项目交付的那些供应商家。
