Site Team: Admin, HSE, execution, quality, store & CPE departments are to be involved to achieve 100% clients satisfaction. STEEL BUILDING PROJECT ERECTION PROCESS AT SITE

15. STEEL BUILDING PROJECT ERECTION PROCESS AT SITE We will engage highly skilled experienced engineers, foremen’s, Supervisors & highly skilled workers to handling the erection activities with safety & quality norms. All staffs & workers shall be used required PPE’s and while carrying height execution works they will be used safety hardness (belt), Fall arresters with ropes and proper anchored life line wire ropes. As per clients approved with ISO system stamped drawings shall be carried out for erection works. Before start up the lifting works the crane which will be used for entire building erection, the crane shall be tested by govt approved TPI agents. We will ensuring that from stacking yard at site the required floor fabricated items only to be shifted in to erection location. And before lifting the items we shall ensuring that all lifting tools are tied properly or not. And also the same should be free from any damages like bends,twistes, dusts & foreign materials etc.. During tying the slings with structures, we shall use rubber packing's to avoid any kind of scratches In order to complete the project successfully we shall follow the right variable procedures as per suit & site with clients approvals.

16. STEEL BUILDING PROJECT ERECTION PROCESS AT SITE The Approx. dimensions of the to be constructed building is length – 27100MM, Width – 21850MM, Height – 35740, floors – 13 Nos (KG Marg). In order to complete the entire building construction ( Steel structures + Deck slabs) we are proposing that the single entity lifting & erection system by suitable capacity crawler crane with 61m boom length. For this crane movement the area clearance (min 8m) should be mandatory around the to be constructed building. The important think is after finishing the each floor reinforcement castings with required curing period, then only we could be started next up floor columns erections on respective foundation bolts. Hence we could be started the steel columns erection eighter from LHS or RHS corners with single crane. All horizontal beams are shall be connected with their respective columns with bolting joints cum required torqueing. So we need to erect first selected rows columns only after achieved suitable strength on vertical columns then we could erected respective rows beams and do the suitable connection methods. The same method shall be followed up to both directions like longitudinal 25m & transverse 25m Once completed the both side required distance, then inspection to be carried out about levels, alignments and dimensions are matching with approved drawings or not, if matched then all structures bolts joints torqueing to be done. After final inspection the particular portion shall be released for civil works. At same row next 75m we should follow the above said way to complete the buildings respected floor. And with said floor construction method shall be followed each floor constructions. OR After erected of all floor steels then civil works shall be constructed, the same will be not suitable for safety execution.

Pranjal Projects Pvt. Ltd. STEEL BUILDING PROJECT Major Steps And Sequence of Activities for Erection

19. STEEL BUILDING PROJECT GENERAL REQUIREMENTS Ensure clear access to work site. Confirm type of MLC Parking and its extension as per approved plan & profile before shifting the material at site. Security staff should be positioned on the site to avoid missing of members shifted to site. Proper demarcation and sanitation of area from other entrants. Ensure availability of an approved MULTI LEVEL CAR PARKING drawing before start of work. The method and stages of MULTI LEVEL CAR PARKING should be discussed and explained to all the staff involved in MULTI LEVEL CAR PARKING before starting the work on each day. Multiple commands must be avoided, no one should interfere in the guidance given to the riggers and crane operators. This section covers the various methods and practices employed in assembling and erecting self-supporting latticed steel structure. Structure foundation and the dimensions between Structures attachment points shall be checked prior to erection.

20. i . Handling and Storage of materials: During unloading, handling and storage of structures, care shall be exercised so as not to damage the surface coating or deform the members. Materials shall not be dumped, dragged, rolled or dropped but shall be carefully loaded, unloaded and stored. A mechanical means such as Fork lift or crane shall be used when materials cannot be properly handled or placed by hand . Bare wire rope or steel chain shall not be used for handling without adequate protection of surface coating. Heavy members shall not be stacked on top of lighter members. Structural member shall be stored according to size, lengths and markings. The maximum weight of steel bundles shall not exceed a specific weight, typically 1600 kg to 1800 kg to facilitate handling and unloading. Member with dissimilar finishes shall not be stored over one another to minimize discoloration of the Structure members. All members shall be placed on wooden blocks to ensure that the materials to be stored are not in contact with the ground. Blocks shall also be used to separate layers of stacked materials. Members shall be supported in such a manner as to prevent bending and distortion as well as to allow water to drain from the materials.

21.   ii. Erection by Crane: MLC Parking shall be erected by means of Cranes of suitable capacity. For all Normal Height Structures, 60/75 Ton cranes may be utilized and for MLC Parking, Special 250 Ton cranes shall be utilized. MULTI LEVEL CAR PARKING work on any Structures foundation shall not take place until the concrete has achieved strength of at least seventy five percent (75%) of the specified comprehensive strength. However, in no case shall MULTI LEVEL CAR PARKING can start prior to (8) days after pouring the concrete. When handling assembled portions of the structure, belts / web slings shall be used to avoid distorting or overstressing members and to maintain the true geometric shape of the section . Adequate tag lines shall be used to ensure that no section of the Structure being lifted will drag on the ground or against any section of the Steel building already erected. At all times at least fifty percent (50%) of the bolts in each connection of the erected members shall be inserted. Until all the bolts in the face of a section of a Steel building are inserted, those bolts inserted in that face during erection shall be “hand” tightened. Temporary guying may be required when erecting a structure in sections. Any temporary guying system shall be checked to ensure that the structure section is stable before workers are allowed to work on the section. Structures shall be completely erected, correctly oriented, with all members in place, all bolts and pal nuts (locknuts) installed and properly tightened, and the entire structure checked in accordance with the specifications. The use of a crane is generally an efficient method of erecting latticed steel structures. With ground pre-assembly of sections, the time spent in final erection can be generally reduced. Cranes with telescoping booms can be more efficient than rigid boom cranes in rough terrain. Considerable productivity can be lost in the process of assembly and disassembly of rigid boom cranes. In addition, continuous handling of boom sections can lead to boom damage. Preplanning of the crane location at the structure site allows for any necessary grading work (Building of ramps, soil stabilization etc.) to be accomplished during the foundation Construction operations when suitable equipment is available at the site. Depending on soil Conditions, additional bearing support may be required under outriggers, tracks, and tires.

22. iii. Crane positioning:   Care shall be taken while positioning the crane. If there is an existing Power adjacent to the proposed Structure Steel building under construction crane shall be positioned in such a way that operations are away from existing electrified/Utilities & also the crane shall be solidly earthed before start of work & after positioning in order to avoid electrocution due to Induction. Technically 5.00 meter clearance is required for Construction but to avoid Induction hazards & as per work practice at least 10 m clearance shall be maintained from the existing Power line conductor and nearest part of portion of Tower part being lifted for Erection.   iv. Site Access:   Site supervisor ensures safe and reasonable access to vehicles and personnel to site and ensures that all escape routes are un-obstructed.   All the working area shall be barricaded by warning tape and warning signs. The location of the crane shall be scanned to identify any underground services particularly at the position of out riggers. Where underground services are identified a steel plate shall be placed over the area.   viii. Lift Preparation:   Site supervisor confirms the following: Information on lift plan and sketches including a re-assessment of load to be lifted. The stability of the load and crane Tag lines are fitted. The lifting slings or chain are correctly secured to the load. All hand signals by Riggers are correctly and clearly given and sufficient time to allow for crane operator response. Tag lines are attached to the load When setting up the crane for lifting the fully extended outriggers shall not touch any existing facility.

23. v. Saf Safe Work Practices during Installation of MLCParking : During erection of structural steel membrane or grating the Supervisor/Foreman shall take necessary steps to protect the employee who are exposed to fall hazards while working at higher elevation. The following safe work practices shall be ensured: a. Only trained workers are allowed to work at height b. 100% Tie off policy will be complied as follows : • Usage of Double lanyard ( while moving around the construction – One Lanyard is firmly hooked always while the other is removed for hooking on to another part ) • Attachment to Fall arrestor is always in place c. Workers shall have no other duties other than the specific job of working at height

24. Table: Recommended Bolt Torque Bolt Diameter (mm) Bolt Torque (N-m) 16 141 32 519 During assembly and erection, members shall not be bent or overstressed to force them into place . In extreme cold weather the assembly or erection workers shall exercise care to avoid subjecting members to sudden stresses, which could cause brittle fractures.

25. 02-Safety Culture Hazards associated with steel structural erection V ary at each location, depending on types of material sizes of structural and the other working conditions. PRIOR TO ANY PROJECT A COMPREHENSIVE JOB HAZARDS ANALYSIS IS REQIURED TO IDENTITFY THE POTENTIAL RISKS AND ESTABLISH APPROPRIATE SAFETY PLANS a ccordingly. Pranjal Projects Pvt. Ltd.
