United States14.5 Risk management assessment will identify the partiesthat are in the best positi

    16、on to control and be responsible for thedifferent risks.5. Performance Requirements5.1 Safety PracticesSafety practices should follow theguidelines of OSHA 29 CFR Part 1926 and other state andlocal regulations. The installer should refer to OSHA, state,and local regulations before work begins. These

    17、 guidelines willaddress confined spaces, a competent person, safety training,structural hazards, trench safety, manhole safety, traffic safety,and equipment safety.5.1.1 Confined SpacesPerhaps the most dangerous ele-ment of safety risk is exposure to underground confined spaces.In the United States,

    18、 OSHA requires that confined spaceentrants, attendant, entry supervisor, and rescue team betrained, provide special equipment, and follow certain proce-dures when entering a manhole or underground sewer. Theattendant must be equipped to test the atmosphere, monitor theatmosphere and the crew, contro

    19、l the activities in the confinedspace, and call an emergency response team for any accident.Besides the air atmosphere, the confined space crew mustrecognize and protect members from sewage or water in thesewers, which can injure or drown a crew member.5.1.2 Structural HazardsWhen cleaning, inspecti

    20、ng, re-pairing the sewer, or installing and maintaining and changingthe fiber and conduit, the crew should inspect entry structuresand large diameter sewers for structural deficiencies, andconsider possible point collapses, which could flood the pipewith sudden infiltration, or subject the crew to o

    21、ther hazards.Therefore, appropriate judgment and other precautions shouldbe considered.5.1.3 Trench SafetySome open trench work or directionaldrilling is required for interconnections and for final connec-tions to users and other telecommunication companies. Acompetent person trained to recognize da

    22、ngerous conditionsand to protect the crew must be on site. The most commonsafety concerns in open trench work are cave-ins and otherutility hits. Therefore, shoring, trench boxes, manhole boxes,ladders, locating equipment, and air atmosphere monitoringdevices are needed to perform these activities.

    23、All OSHAconstruction standards must be followed.5.1.4 Traffc SafetyCrews cleaning, inspecting, repairing,installing optical fiber and conduit, repairing sewers andmanholes, and installing new conduit in open trench may beexposed to traffic. U.S. DOT MUTCD Part VI requires thattraffic control devices

    24、 and flaggers must be in place to protectthe crew and the public, if there is exposure to traffic. Acompetent person should be in charge of these activities.NOTE 1The AGC4offers information on Safety, Constructability,Liability and Risk Management, and Partnering through its website.Additional infor

    25、mation about constructability issues is available at thewebsite www.engr.wisc.edu/cee/courses/cee596.html, which is the “Con-structability Analysis” course at the College of Engineering, University ofWisconsin-Madison.5.1.5 Equipment SafetyAll construction equipment andpersonal protective gear must

    26、meet OSHA regulations, and bein good repair. Crew members should receive proper training insafety for all exposures, and weekly (more frequent if war-ranted) safety meetings should be conducted to identify antici-pated hazards, and plan appropriate processes to protect thecrew and public from injury

    27、 or death. Prior to starting a project,a safety plan should be prepared by the installer or ownersdesignated representative. This plan should be implementedand followed during the construction.NOTE 2Safety videos are available from various vendors, including avariety from the AGC.5.1.6 Manhole Safet

    28、yWhenever optical fiber devices areinstalled in manholes, certain procedures are used to protectpeople entering the confined space in the future. Cable bendguards are to be closed to avoid a tripping and entanglementhazard. Where practical, splice enclosures are to be installednext to the manhole st

    29、eps or ladder so that workers or rescueworkers can get into the manholes with self-contained breath-ing apparatuses without hindrance or risk of entrapment.5.1.7 Installation SafetyCertain electrically powered de-vices for cable installation, such as robots, can have anelectrical potential differenc

    30、e from the pipeline. An electricalfailure in the robot and certain conduit attachment methodsmay create sparks. Engineering and construction professionalsshould assess the conditions and methods, and use appropriatesafety measures to guard against any potential explosion orelectrical shock hazard.5.

    31、2 Access RightsAs in any construction project, accessrights are extremely important for constructability, timelyexecution of the project, legal risk management, and publicrelations. It is recognized that for a project to be constructable,the installer must have access to sewers, manholes, streets,pu

    32、blic and private property, and be able to execute the workwithout interfering with other public or private activities.NOTE 3The APWA5has manuals covering procedures for streetaccess management.5.2.1 In the initial stages of the project the telecommunica-tions company (or equivalent) will contract wi

    33、th the sewerutility for the use of its facilities. Consideration should begiven to all needed access to sanitary and storm sewers,manholes, streets, and temporary street or “parking” access forall construction activities, including temporary pumping dis-charge piping and storage of job materials.5.2

    34、.2 If street closures or partial closures are needed, thestreet utility director needs to be contacted and necessarypermission acquired prior to construction. Barricading ofstreets, lane closures, and other traffic rerouting should becarefully planned and the designated authority should givepermissi

    35、on to perform such activities.5.2.3 Construction equipment needs should be planned,including enough room for maneuvering equipment and con-struction materials. For instance, sewer cleaning, pumpingequipment, generators, directional boring machines, and open4Available from Associated General Contract

    36、ors (AGC) of America, 2300Wilson Blvd., Suite 300, Arlington, VA 22201, http:/www.agc.org.5Available from American Public Works Association (APWA), 2345 GrandBoulevard, Suite 700, Kansas City, MO 64108-2625, http:/.F2233 03 (2015)2trenching equipment all require enough real estate to performthe vari

    37、ous operations efficiently and safely. If private propertyis needed for equipment operating processes, agreementsshould be obtained prior to construction.5.2.4 Certain interconnecting lines, open trench conduitinstallation, and underground cable plowing will be requiredon public and private property

    38、. The procedures in this guideshould be implemented to obtain access and to maintain opencommunications among installers, property owners and thepublic. After open trench conduit installation or plowing,restoration work should be completed as soon as practical inaccordance with local regulations, so

    39、 that public access andgood public relations are maintained.5.3 ConstructabilityA project is considered constructablewhenever the contracting parties and design professionals havetaken into consideration the various challenges that the con-tractor or installer will face when performing the construct

    40、ion.Constructability issues such as ample room in work areas,isolation from traffic or the public, existing conditions, timeconstraints, weather conditions, safety exposures, completeplans, permits from other utilities, teamwork, flexiblecontracts, involvement of all parties affected, and good engi-

    41、neering practices, all contribute to how a job is accomplished.These factors also make the project more suitable for bidding.During the constructability review, the parties may emphasizevalue engineering to provide the most cost effective project.5.3.1 When access routes are obtained, a holistic app

    42、roachshould be considered in the plan. The access must consider theneeds for the facility to be built, the size of constructionequipment, the need to maneuver machines and materials,access to the site for equipment and materials, temporarystorage of materials and equipment, traffic, emergency vehicl

    43、eaccess, and adequate room for the safety of the crew, includingany safety equipment required. This planning should be con-ducted by seasoned and experienced construction profession-als.5.3.2 Existing conditions should be part of the engineering.For instance, when working underground, existing utili

    44、tiesmust be located to protect workers and the infrastructure.Allow enough room for workers and safety devices. Thetopography plays a role too. In a low area, possible flooding ofthe construction activities should be anticipated. If trafficaffects construction and cannot be rerouted or controlled,an

    45、other plan should be adopted. The condition of the existingsewers and manholes must be known, so that during theconstruction, adequate restoration work can be budgeted.5.3.3 The construction time and schedule should be basedon sound construction and site condition factors. Duringproject conception o

    46、r engineering activities, or both, a prelimi-nary construction schedule should be prepared and approvedby all of the parties. Construction activities should be brokendown into elements and sequenced chronologically. Climate,weather conditions and holidays should be considered in theconstruction sche

    47、dule. Adequate time must be added for safetyactivities. If construction activities are constrained by certainrestrictions, such as work only at night or during off peak trafficconditions, time should be adjusted for labor efficiency. Expe-rienced managers should be involved in the schedulingactiviti

    48、es, using critical path scheduling software.5.3.4 It is good practice to assemble a comprehensive teamto plan the project. Team input from engineering and construc-tion professionals, public and private utility staff, telecommu-nications staff, and legal entities throughout the conceptual,design and

    49、 construction phases will provide the best project. Ateam approach brings in more expertise, and creates “buy-in”by the various team members.NOTE 4The AGC has a video and pamphlet on partnering which canhelp guide the team through this process.5.4 Liability and Risk ManagementThe responsibilitiesand authorities of the parties involved in the planning,engineering, construction, operation and maintenance of theproject should be identified.5.4.1 Risk should be assigned to the party who has controlover the particular risk.
