Leading unit intervened in advance, and the owners of old buildings ran less errands
"One-time approval is passed, saving too much trouble!" On the 24th, Mr. Zhang, who lives in Qianfoshan East Road, learned that the design plan for installing an elevator in his unit building passed the project planning review, and breathed a sigh of relief. Lao Zhang introduced: His own unit building is the fourth unit building in the community to install elevators. The first three unit buildings did not go so smoothly. "I tried hard to design the drawings, but I was returned or asked to rework because they did not comply with the policy. It was really troublesome." The reason why
was able to pass the approval so smoothly, in addition to the experience of the first three buildings, Mr. Zhang also believed that they also benefited from the "report of additional elevator projects" added by the new "Guidelines", "Thanks to the leading unit to check first, saving a lot of trouble."
"Previously, after finally negotiating and agreeing, when I took the construction drawings and design plans of the design institute to go to the planning department for review, I would often be returned or reworked because I did not meet the requirements." An industry insider said.
According to the new "Guidelines", after the owner of this unit reaches an agreement on the matter of adding elevators and signs all written agreements, the applicant or implementing unit shall apply for project filing from the leading unit for adding elevators in existing residential buildings in the district. When completing project filing procedures, the leading units of each district should also solicit preliminary review opinions on the preliminary design plan for the addition of elevators from the planning department.
In other words, in the early stage of installing elevators in the old building, the leading department must intervene and check in advance. This control mainly takes two aspects: one is to provide preliminary control on whether the elevator project complies with Jinan's policies; the other is that the leading department also helps the owners conduct preliminary consultations with the planning department on the preliminary plan, connect with the planning approval department, and communicate in advance on the preliminary plan.
In addition to letting citizens run less errands, the new "Guidelines" are based on the current situation of "the design drawings of many old buildings are difficult to find and lose", and have made targeted supplementary regulations to facilitate the establishment of an elevator to successfully pass the approval of the fire and security inspection departments.
cancels the length of the corridor, and it is easier to pass the review of the flat-floor households
It is reported that most elevators installed in old buildings in Jinan City currently adopt a split-level installation plan, that is, the elevator stops are located on the 2nd and a half, 3rd, 3rd, and 4th and a half respectively. After taking the elevator upstairs, users must climb half a floor to get home. Only some communities adopt a flat-floor home access plan, such as the two elevators in Building 8, the Qianfoshan Campus Door of Shandong University. The elevator entrance and exit are located on the wall of the yard of the residents' home, and users can go directly to their homes.
Since the end of last year, the elevator in Building 8 of the Qianfoshan Campus dormitory has been completed and used, owners of other unit buildings in the dormitory area have also taken action. Since it is the same dormitory area and the building structure is roughly the same, after discussion, many owners advocated the adoption of the "flat floor entrance" elevator installation plan of Building 8.
The owner Mr. Zhang said that after the opinions upstairs and downstairs were consistent, the design plan was submitted to the planning department for review. However, according to the previous provision of the "Guidelines" that "the length of the corridor should not exceed two meters", the installation plan has not been passed.
For this reason, the elevator installation project department of Shandong University discussed and revised the design plan with the owners many times. "Take the Donghu as an example, from east to west, there are bathrooms, living rooms, and kitchens. The entrances and exits of the corridor are set in the bathrooms and living rooms, which are not conducive to the convenience of owners' lives, so the entrances and exits can only be set on the owner's kitchen wall." Staff of the project department of Shandong University's elevator installation said that due to the building structure, the length of the corridor is mostly more than two meters.
Coincidentally, the elevator installation projects of several unit buildings in Sunshine City and refinery dormitories were also stranded due to the regulation that "the extension length of the corridor should not be greater than 2 meters."
The promulgation of the new "Guidelines" has brought things a turnaround. The new "Guidelines" stipulate that if the flat floor directly enters the house, the entrance door should generally be at the shortest distance close to the first house (except the bathroom) on the elevator side, and the width of the corridor should not be greater than 1.5 meters, and should not be less than 1.2 meters. The provision that "the length of the corridor should not exceed two meters" is replaced by "the entry door position should generally be the shortest distance from the first house (except the bathroom) on the elevator side."
"The previous requirements in the Guidelines may also be to prevent owners from increasing indoor area by installing elevators, forming new illegal buildings, etc.." Li Xiaozhong, an elevator expert in Jinan City, said that from the perspective of urban governance, similar regulations are necessary. "The new Guidelines further clarify the policies and properly solve the dilemma of "using the installation of elevators to increase indoor area". In this way, it can be expected that the flat-floor household registration plan will be relatively easy to pass the approval. The new guideline "
has strict requirements and effectively reduces market chaos
" The release of the new "Guidelines" is conducive to rectifying these market chaos. "Tang Xiugui, general manager of Shandong Zhengxun Elevator Co., Ltd., said. The new guideline is more strict in the review of building exploration and other links in the early stage of construction, and in the control of the quality control of steel frames such as wind and earthquake resistance. "For large and medium-sized elevator companies, because they originally had a complete set of standardized construction processes, the impact is not too great; but for those irregular small enterprises, the new "Guidelines" means higher costs and higher requirements for installation technology, which is undoubtedly a serious blow. ”
New "Guidelines" stipulate that the health of the original building should be reviewed before installing an elevator. The new "Guidelines" stipulate that before the elevator design, original data such as survey reports, construction drawings and other original materials of the original building should be collected in advance. When the data is incomplete, necessary supplementary and actual measurements should be conducted. During investigation, the feasibility of adding elevators should be analyzed from the three aspects of safety performance, seismic performance, and foundation deformation based on the current status of the original building and the original data, construction quality, maintenance and safety conditions, and foundation deformation.
It is worth pointing out that the new "Guidelines" clearly state that when the building is a masonry structure, the following situations exist One of the things, elevator additions should not be carried out without identification and reinforcement: early construction, no seismic design, and no seismic measures were carried out; load-bearing wall demolition and modification are serious, and no reinforcement treatment measures were taken; main seismic measures such as the minimum size of load-bearing walls, ring beams and structural column settings do not meet the seismic standards at that time; foundation deformation causes the overall inclination of the house to exceed the specification standards or the load-bearing wall to crack, and the settlement is not stable.
In addition, the new "Guidelines" also add construction drawing review, that is, the review procedures for construction drawing design documents. "This series of regulations are aimed at ensuring the safety and reliability of elevator design plans and later use. "But Tang Xiugui also admitted that the increase in the above links also means that the materials submitted for review are more detailed than the previous requirements, and the design cost will increase accordingly. "For example, the new "Guidelines" require the issuance of calculations for buildings, but most old buildings do not have them and need to be re-surveyed and mapped, which means that the cost must increase by 10%. ”
