B.l Handlin g Over and Mobilization

Coinciding with the award of contract and in order to sign site handling over memorandum, IMS technical team dedicated to the project will visit the site to find out the actual conditions and its availability to commence the works. Immediately after site handling over, Mobilization will be progressed according to the contract conditions within the period assigned in MEP time table.

B.2 Planning and Scheduling

I.M.S will subm it for approval the MEP time schedule. OetaiJed MEP activities will be scheduled within the overall project time table to define the time !Tame of each and every item, milestone and/or activity using Primavera software P6. 1. The MEP schedule will permit to indicate the percentage of completion, resources and updates according to the actual situation of execution whether ahead or behind schedule.

B.3 Engineering

B.3.1 Technical Submitt als and Quality Assurance Forms

Accord ing to technical documents of the project, a complete techn ical submittal for each and every type of material , equipment and device(s) will be submitted to the Engineer for approval. Technical submittals will generally include but not limited to the data sheets, technical information, catalogues,calcu lation , ctimension , weights and any other information may be requested by The Engineer or Owner Representative(s). Samples associated with each submittal when applicable are an integral part of the techn ical submittals. Meanwhile, a complete set of Quality Assurance forms wi ll be submitted for approval. Q.A forms will include the forms of Material Technical Submitta l (M.T.S), Materia l Inspection Requests (M.T.R), Installation Inspection Request (I.R), Request for Information (R.F.I), Field change Request (F.C.R) and interim payment certifi.cates.

B.3.2 Method Statement

I.M.S understands the general concept of the Method Statements as the only way to detail how a particu lar task or activity will be carried out. Method statements are always 'Site Specific' and are used to control the operation and to ensure that all concerned are aware of the hazards associated with the work and the safety precautions that need to be taken. The method statement must also detail which control measures have been introduced to ensure the safety of anyone who is affected by the task or process. As Method statements contain information concern ing the order and method of construction with reference to work procedures and safety controls,I.M.S considers method statements in fact as a contractual requirement , requiring submission to the Principal Contractor, client or Engineer for approva l prior to the commencement of works. Therefore, Method statements in I.M.S are written by a competent staff that is familiar with the work processes and they cannot be generic or off the shelf. Method Statements time frame(s) shall be included in MEP time schedu le.

B.3.3 Shop drawings

On the engineer approval to the technical submi ttals of each activity and based on the intervals governed the time schedu le of work shop drawings of different activities wi ll be issued for engineer approva L Work shop drawings are the first step of how to make the concept explained inmethod statements comes true. It includes full details of what to be installed, how and where. Work shop drawings include details of material as per approved technical submittal, routing as per actual conditions on site, levels as per architecture requirements, locations studied to match the construction elements and calculations, and all other requirements needed to comply with standards, international and local regulations. An integral part of the work shop drawings are the complete, sectional and/or detailed views to explain the parts of installation which seems to be mystery, not clearly shown on the plans and essential to be solely explained to guarantee a successful installations. Work shop drawings scale is normally 1:100 unless it is better for all concerned to have other scale like 1:50 or larger for the sake of better installations.

msB.3.4 Composite Drawings

The attitude of fMS is to issue work shop drawings of an MEP activities fully ooordi:nated with eadn other, with actual site conditions regarding dimensions and levels1 structurnl elements like beams, columns and concrete dimensions taking into CQllStderation the .finishing Requirements as a top priority .. IMS be1ieve in 'Cbe benefits of composite dr,awiogs whicb may be sununarized as following: •Highljghts plan discrepancies and missing/insufficien t information provision to effectively :install MEP activities in oonjuncti on the construction parts of the project, with mimimal time Jost •Allows bettei contro of cost and time in the schedule ,of works; and henc,e s1noother work performance •Reduces misunderstanding between the vam•ious part ies, invoJv,ed in a project since everyone posse-sses the same development p]ans,

B.3.5 Procurement Plan

A Pr-ocurement Pta:o defines the products and services requir-ed to the Project. A good Procmement Plan wm go one step :Curtner by describing the process you wm go through to appoint those suppHers contractually so that it oompJies with the vendor Ust dediclllted to the projeet. Extracting from time table, a separate detailed procurement schedule will be designed the pJtoject. This detailed procurement schedule wjJL consider tlhe long lead items whether t.bey are locally supplied or 'imported, periods reqllired for fabrication and I or fa,ctory as:sembJy of QtbeJ• equipment, and the materials available on shelf. Itgoes by defaum t that first fix materitds of different activities w ll occupy the frorntsea ts in the sched ule. On receiving the Engineer approval of th e material technical submittal s and workshop drawings, and based on the revision of cost control and financial departments, P.O's will be placed for the selected approved vendors. Inaccordance with the contract conditions, inspections and testing of materials/equipment by Engineer and Client representativ e shall be arranged by l.M.S Q.C engineer whether they are onshore or offshore.

B.3.6 Installations

It is the stage of converting all the cards described above into visible reali ty on the ground. Governed by the project time schedule, the approved workshop drawings, delivered material to site, method statements and the composite drawings will guide perfectly the installation process of all MEP activities. First fix embedded activities and allocations of builder's works like openings and box outs in slabs and concrete walls wi ll be the first step to pursue the civil works and semi­ finishing works like plastering and insulation of floors. Fix ing of supporting system like hangers and supports of the exposed items will commence in timely manner representing the start of second fix process which will allow for installation of the exposed activities of all trades. Erection of equipment's with their hook ups and final connections to the network s with the essential partial tests will be progressed simultaneously. Final fix includes air outlets, cladding, wiring device faces ...etc. is the last step of compl eting the insta llations and put the works at the stage of fmal touch which is the overall testing, commissioning and start up . In all the above stages, the quality control role will be implemented to assure the high quality of installation to comply at least with the requirements of the technical specifications of the project, and also to apply the Engineer inspections to the works in the appropriate time and manner.

msB.3.7 As-Bwilt Drawings and Manuals

After the completion of the project; t ms a man datoryt o provi de ac•curate as-built d -awrngs of the services instaUed in its completed state. This ensures that the cl•ient could benefit from efficient and cost effective future fac:Hities Illanagement. Operationa l and Mamntenance Manuals are also issued to help the client fully and effectively operating the services installed.

B.3.8 Commissioning And Start Up

Building commissiom ing is the process of verifYing that all the subsystems :for HVAC., pl• umbing, electrica12 fire/life safety, utility plants) sustainable systems, lighting,. wastewater,. controls, !building security etc .. achieve the o\yner's project requirements.. Build ing commissioning is a quality-foc used process necessary for construction pt•ojects.NormaUy the initnal eommissiordng team is involved fr:om _project initiation through one year of occupancy.Tber•e is an on-going building enhancing and commissioning program and team for the life of the building.
