1.after engineering Be finished, cement works engineering also the same period complete work, so whether the cement works' engineering should take part in finishing construction of engineering to check Accept?Elaborate reason. The cement works should not take part in finishing construction of electrolysis aluminum engineering acceptance. The reason is:With outside buy cement to compare from setting up cement works to supply the cement that engineering needs, just supply a way different, with electrolysis The aluminum engineering has no direct of connection. 2.long distance power line the road and power supply the power point Be finished behind whether should bring into two engineerings to carry on finishing construction acceptance?Why? Long distance power line the road and power supply the power point should not bring into two engineerings to carry on Jun D acceptance after being finished. Reason:a is the electrolysis aluminum engineering item to make a contract two engineering power supply the project just was placed in argument and chose a line stage; Two is invest outlet and construction unit to all differ from should large electrolysis aluminum engineering, belong to moreover a construction engineering item, Should be respectively carry on finishing construction to check and accept an activity. 3.is the owner to whether the holdover penal sum of A construction engineering company is reasonable?Elaborate reason. The owner constucts the holdover penal sum of engineering company absurdity to the A. The reason lies in: ①The power supply engineering belongs to moreover a construction engineering item, is sent by the B to change to give or get an electric shock to constuct companies to accept to set up; ②Engineering holdover because meet a hundred years the weather condition for doing not meet, belong to a force majeure. 4.the construction of the life area obviously want to be finished with 1, 2 engineerings synchronously, whether it should also take part in the large electrolysis aluminum engineering to finish construction Check and accept, why? The construction that lives area should not take part in the large electrolysis aluminum engineering to finish construction acceptance. Because:It a, two engineering property inconformity, live area engineering to belong to public construction engineering; It two, live the area engineering investment outlet and electrolysis aluminum engineering different. 5.in the aspects of promising circuit being safe, does the B send to change to give or get an electric shock to constuct if the gearing of company is correct?Elaborate correct way of doing. The B sends to change to give or get an electric shock the gearing inaccuracy of constucting the company. Reason:correct way of doing BE:220 kV circuit, equip a double to avoid thunder line in response to the whole lineses, avoid on the general pole tower thunder line to lead a linear protection The Cape is a 20 os~30 os. 【The case 1 H 420150-4 】 A, background Large Mr. of some north sets up an electrical engineering, the engineering always constructs area 260,000 ms 2, from AN and B two districts constitute, the AN area function is a five planets Class upscale hotel, building area 120,000 ms 2, B area in order to transact building, construct area 140,000 ms 2.AN and B two area electrical engineering the owner is alone Invite bids, respectively from two construction unit companies 1 with company 2 accept, two area electrical engineering system independence constitution respectively system. The electrical engineering all includes well ventilated air condition, water supply to drain, fire fight, electricity, construct intelligence engineering item.The well ventilated air condition engineering adopts Use ice Xu cold VAV making a cold technique, transacting the building air condition system adoption change amount of breeze system, the air condition adoption breeze machine in hotel dish tube adds new breeze system, Water supply in the toilet drains an adoption together layer catchment system, the engineering establishes to keep drinking system, the fire fight engineering constitution air extinguishes fire system, fire fight to spray Spread system, and penstock system...etc., building big hall constitution floor the radiation adopt warm system and cover up heat-proof to build up of a ground of tube material adoption PE-RT to gather Ethylene tube, network service engine room adoption open type mesh bridge, network service engine room establishes the constant temperature Heng that German original package imports wet air condition Machine set.The electrical engineering construction work expects all for 2 years, item in the hotel starts work 3 month time first, and the item completes work time as December, 2012, The building's adopting warm system has been already circulated. The engineering organization finishes construction acceptance and checks and accepts a personnel and discovers a few problems as follows in the check: (1)One engineering item in the completion hotel of company, company 2 engineerings in the hotel accepting return not yet finished work currently. (2)Company 1 the underground of engineering in the hotel accepting does laundry the steam piping of building engineering, because the owner buy of the equipments holdover be present, past The construction unit didn't link the steam piping good enough by time of engagement as well, the owner was square to start construction the unit carry on penal sum. (3)Engineering in the hotel didn't carry on the system that takes a cold source to associately adjust to try. (4)The constant temperature Heng of the import the manual of the wet machine set has no
