     If your boss asks you to work in Moscow this year, he'd better offer you more money to do so-or

even double that depending on where you live now. That's because Moscow has just been found to be

the world's most expensive city for the second year in a row by Mercer Human Resources Consulting.

     Using the cost of living in New York as a base, Mercer determined Moscow is 34. 4 percent more

expensive including the cost of housing, transportation , food , clothing, household  goods  and

entertainment (娱乐) .

     A two-bedroom flat in Moscow now costs $4,000 a month;a CD  $24. 83, and an international

newspaper  $6. 30, according to Mercer. By comparison,a fast food meal with a hamburger(汉堡包)is

a stea at $ 4. 80.

     London takes the No. 2 place , up from No. 5  a year ago, thanks to higher cost of housing and a

stronger British pound relative to the dollar. Mercer estimates (估算)  London is 26 percent more

expensive than New York these days. Following London closely are Seoul and Tokyo , both of which

are 22  percent more  expensive  than New York ,while No. 5  Hong Kong is 19 percent more costly.

     Among North American cities, New York and Los Angeles are the most expensive and are the only

two listed in the top 50 0f the world's most expensive cities. But both have fallen since last year's

study-New York came in 15th, down from lOth place, while Los Angeles fell t0 42nd from 29th place

a year ago. San Francisco came in a distant third at No. 54, down 20 places from a year earlier.

     Toronto , meanwhile ,is Canada's most expensive city but fell 35 places to take 82nd place worldwide. In Australia, Sydney is the priciest place to live in and No. 21 worldwide.

背景材料:
某高速公路项目,全长45.5km,设计车速为120km/h。路面面层采用C30钢纤维水泥混凝土。该项目施工单位对面层的施工过程如下:
第一步,该施工单位按要求进行水泥混凝土配合比设计,采用实验室确定的“实验室配合比”直接配料;
第二步,施工单位按要求架设模板;
第三步,配备一座间歇式搅拌楼,由于该搅拌楼刚从附近工地搬迁过来,且未超过标定有效期,该施工单位在确认试拌合格后,认为没有必要重新进行标定;
第四步,对搅拌混凝土进行现场取样,做水泥混凝土抗压强度试验;
第五步,采用必要的运输工具将新拌混凝土在规定的时间内合格地运到摊铺现场;
第六步,采用小型机具铺筑法进行摊铺和振捣施工;

第八步,按要求进行各类接缝的设置与施工;
第九步,按要求进行混凝土的养生;
第十步,养生期满后,采用软拉毛机械进行抗滑沟槽施工;
第十一步,清除混凝土板缝中夹杂的砂石、泥浆、尘土及其他污染物后进行灌缝施工及灌缝养生。
2.问题:
(1)施工单位进行配料采用的配合比正确吗说明理由。
(2)你认为该搅拌楼是否应该重新标定
(3)除水泥混凝土抗压强度试验以外,还应该进行什么试验
(4)以上施工过程采用的各类施工机械中,请你将不合理的部分改正过来。
