3床半独立式住宅。地面和一楼的烟囱25年前就被拆除了。阁楼烟囱仍在。有人说我们需要插入一根钢梁，于是叫来了一家结构工程公司来评估阁楼和烟囱，进行测量和计算，还要求进行总体结构检查。他们派出了一名结构技术员，他是结构工程师协会的准会员，但却是一名合格的特许测量师(但预订时告诉我们他们会派出一名工程师!)阁楼是空的，有一个可以站的地板和一盏灯，所以很容易进入一切。技术员在阁楼里呆了大约5分钟，环顾四周，踢了踢烟囱附近的支架，拍了几张照片。他说我们肯定需要钢梁。然后他走出阁楼，看着下面的地板。我们想知道墙壁和地板在结构上是否安全。 The room was empty, no furniture, easy to lift carpet and we asked him to check and offered to lift the carpet for him. He insisted it was not necessary – we did it anyway as it was necessary to ascertain the old position of the chimney, and had to prompt him as to the location of the old chimney and the cement in the floor, which he did not notice. After a brief 5 minute look downstairs he wanted to leave, at which point i reminded him about the calculations and measurements, as we had not seen him measure anything or use any tools at all or take any notes – he only took a few pictures. He was very reluctant to do the measurements, and gave several reasons as to why he could not do them. 1. he was not instructed by the office he needed to – so we phoned the office as this is the service we had clearly booked and asked for, and 2. he was only an associate member of the ISE and so not insured to do the job. Whilst we were on the phone to the company’s customer helpline the technician proceeded to take only two measurements of the main load bearing wall in the living room user a laser device and then said he had to leave. After this, we finally got a call back from the company offices who called the technician. They called us back and assured us that he took all the measurements needed for calculating the dimensions etc of the steel beam. I mentioned that he did not take measurements in the loft but was told maybe he did not need to do this. Myself and 2 others were present and we did not see the technician take a single measurement in the loft, so I am quite worried about what measurements he is going to present to the engineer for calculation. How will I know it is safe if he didn’t even measure anything in the loft? Does anyone know what should have happened if this was done properly? Who should do the measurements? What do they measure? What tools are used and how long should it take in the loft? And who is qualified to do such a brief? What should I do as we will be invoiced for a service we did not book!
