Mobilization & Establishment of Site Facilities

 

UEI will perform their pre-construction activities from their Main Office in Doha.  Site offices complete with telephones, fax, computers, printers etc will be established, together with all necessary Stores, Workshop, Site sanitation facilities for office staff & workmen and First Aid facilities.

            

 

PROJECT MANAGEMENT OFFICE – JOB SITE

 

            The Site Office primary activities are summarized as :

 

            UNITED PROJECT MANAGEMENT REPRESENTATIVES

            IMPLEMENTING THE SCOPE OF WORKS

            MAN MANAGEMENT / LABOR CONTROL

            MATERIAL REQUISITION

            PROGRESS MONITORING / VALUATION OF WORKS

            HEALTH & SAFETY

 

The aim of the project manager is to carry out the work efficiently to achieve completion within the cost limitation of necessary of the contract sum.  Company policy is to manage our proportion of the work and if necessary other trades , to succeed.  In the absence of realistic recourse to contract law taking a heavily contractual and negative stand will only cause bad feeling. A more imaginative approach is favored to achieve results

          

 

It is essential to commence work in an efficient and effective manner.  it is so often the case that more time is lost on site in the opining few weeks of a project than at any other.  Time lost is rarely recovered so as far as is possible each week should be treated as the last.

 

The Project Manger is the highest authority on site.  He has full control over the works and is empowered to represent the company and make decisions he sees fit.  He is responsible to the Operation Manager and may call upon the support of the Main Office at his discretion.

 

Project Team

 

UEI will establish a dedicated project team in Doha to undertake the project responsibilities.  This includes planning, drawings, procurement, installation, QA/ QC, Safety, Testing & commissioning activities.  This team will also be responsible for the co-ordination and incorporation of all data provided by the specialist equipment suppliers and subcontractors.

 

The project team will initially undertake a detailed review of the Project to ensure that the scope of work is fully identified and reflected in the project construction program.

 

A detailed project construction program will be prepared / submitted for approval soon after the award of the contract which will include :

 

  • Mobilization
  • Site facilities
  • Drawing Submissions
  • Material Submissions
  • Installation activities
  • Pre-commissioning activities
  • Testing & commissioning activities
  • Inspection & Approvals from Statutory Bodies / Local authorities
  • Demonstration of interface / integration of various systems
  • Snagging / Punch lists / Sign Off
  • Handing Over of systems & spares
  • Submission of As-Built drawings / O&M manuals
  • Training of Client’s operatives
  • Project completion
  • Demobilization

 

            

Drawing and material submittals with supporting data will then be prepared and submitted for approval in a timely manner to suit procurement / installation requirements and milestones.

 

All documents will be strictly in accordance with the approved Project Quality Manual.

 

Drawings

 

It is the intention of UEI to use as much as possible of the drawings and specifications issued for construction.

 

UEI will  prepare and obtain approval of the Project Consultants for the following :

 

Builders-work Drawings         

Installation / Shop / Fabrication Drawings

MEP services co-ordination drawings

Schedules / Schematics / Calculations / Charts

As-built Drawings

 

The procedures of the Drawing Offices will comply with the requirements of the approved Project Quality manual of UEI.

 

Material Proposals

 

Place of Manufacture

 

The manufacture of the approved equipment & materials will primarily take place at manufacturers works.

 

The procurement of various electromechanical equipment will take place in accordance with the quality procedures, which are independently audited.  This will ensure that only materials suitable for purpose will be delivered to site.

            

Packing and Delivery

 

After factory tests the equipment will be disassembled if necessary for shipment and shall be suitably packed at the manufacturers’ works for shipment to site.  Delivery to Doha shall be generally by sea freight packed in standard 20ft or 40ft containers with special containers as appropriate.  Any oversize, heavy lift items will be shipped break bulk.  Cables will be shipped on cable drums in sizes and weights such that they are economical for shipping.  From Doha port the plant shall be transported to site by road.  The equipment will not be reassembled until it is positioned in its final location.

 

Manufacturing and Delivery Periods

 

 The manufacturing and delivery periods for the major items of plant will be indicated in the Tender Program to suit the access date and power-on dates indicated in the preliminary program.  

 

Site Storage

 

To minimize the storage of equipment at the works area, deliveries will be planned to coincide with the construction sequence.  Wherever possibly, equipment will be delivered to its ultimate location direct from the ship. Equipment will be packed such that it can be left unopened in the works area for a limited period should it be necessary.

 

Delivery to Site

 

Planning and Co-ordination

 

At the programming stage, access dates for the delivery routes and the installation sites shall be clarified with Authorities and designated contractors. This is particularly important for equipment, which will be delivered directly to site from the port.

 

Progress meetings & regular site visits will be required to update the information about the site progress and to coordinate access and other requirements.

 

Suitability of area prior to delivery of materials

 

Prior to delivery, all arrangements which have been previously agreed with others will be checked so that.

 

  • All access roads are suitable for delivery lorries.
  • The areas adjacent to the entrances are cleared for parking vehicles and unpacking.  
  • Protection is in place on any delicate architectural finishes that may be susceptible to damage.
  • Delivery corridors and plant rooms are cleared of all temporary materials and debris.  
  • Wet trades civil works inside all the plant rooms is complete with permanent doors provided.
  • All doors are large enough for the passage of the equipment.  
  • Background lighting is available at all locations.
  • Suitable hoists and lifting beams are provided.
  • All cable containment provided by the Designated contractor is complete, tested for continuity and identified by colored markings.
  • Proper security control has been arranged by the Civil Contractor.  

 

Delivery Methods

 

Delivery by Road

 

All equipment and materials will be delivered by lorry either directly to the installation site or to the works area.  Normally, a lorry equipped with hydraulic crane will be used, but for heavy lifts, a separate mobile crane will offload the equipment. The equipment will usually be delivered with the shipping packing intact for protection during transit.

 

All cranes, lifting pulley blocks and slings will be fully tested and certified and visually checked each time.  All materials will be properly secured on the lorries.

Movement from point of offloading to final location will be done by the use of lift trucks or skids, as appropriate, along the designated delivery routes.

 

Installation Proposals

 

The installation will be carried out under the control of the respective Project Manager.  Installation specialists from certain manufacturers will also be utilized. Our installation methodology is set out below.

 

Planning and Coordination

 

During the planning stage, all relevant information about the assembly methods of the equipment will be examined to check the requirement for special tools as well as site requirement in terms of floor leveling, floor fixing methods and clearance.  Detailed method statements will be prepared and agreed prior to any installation commencing.  These method statements will clearly identify the proper sequence of working; highlight any safety risks and the action to be taken to mitigate these risks.

 

Interfaces with Designated Contractors will be identified and recorded.

 

The works program will be developed to indicate that the works can be installed within the time restraints of the project.

 

Site Possession

 

Prior to installation work commencing, a joint site survey with the Main Contractor will take place to ensure that the area is suitable for work to commence.

 

Generally all installation works are carried out concurrently with other building trade contractors and UEI will fully coordinate with them to avoid abortive work.

 

Other contractors would have to take the consent of the supervisor of UEI team if they need to access the area where currently work would be in progress.  Also they would have to arrange all necessary protection to UEI work done in that area.  

 

Installation

 

All work will be installed in accordance with the agreed method statements and monitored by the Project quality plan to ensure the quality of installation.

 

Particular points relating to specific elements of the works are given below:

 

Main Equipment e.g. Transformers, DG sets, Chillers, AHUs, LV Panels, etc.

 

During the design development stage, physical sizes of all equipment will be thoroughly checked with the room sizes, requirements of designated contractors and maintenance clearances.

 

Prior to commencing the installation, the room must be complete, dry and dust free with lockable doors fixed.  The floors must be leveled to within the manufacturer’s tolerances.

 

The installation method will generally be in accordance with the installation instructions provided by the manufacturer and agreed in the method statement.  Most equipment will be sectionalized to ease shipment and will be reassembled on site. Leveling is the prime activity for switchgear erection.  All panels will only be tightly coupled after the level is checked.  Temporary protection will be attached on the instrument surfaces until testing and commissioning.  Tapes to minimize migration of dust will temporarily seal all vent holes on the panel surfaces.  

 

Cables

 

Cable routes will be designed so that account is taken of bending radii, separation and segregation of the cables to be installed.  A thorough review of cable containment provided by Designated Contractors will be undertaken during the design phase.

 

For programming, the cabling exercise will be properly planned so that the cable will be laid in the most economical manner in each location.

 

Prior to installation, all containment will be checked thoroughly to ensure that it has been installed to the working drawings.  Before any cable is pulled the entire route will be checked to be sure that there are no obstructions alone the route.

 

Inside the buildings, the cables will generally be pulled by hand from the drums (mounted on cable jacks) onto the pre-erected tray/hangers, dressed and cleated.

 

Cables running in external trenches will generally be installed using cable winches.  The cable will be transferred immediately to the duct or onto hangers and cleated.

 

All cable cuts will be sealed with proper end caps provided by the cable manufacturer.  

 

Testing and Commissioning Plan

 

Inspection and test plans will be prepared and agreed in advance of any testing.  These will identify what tests or inspections are required, when they have to be performed and what records have to be kept.  The tests will basically follow the test requirement stipulated in the tender document.  The testing and inspection will be generally performed at 3 stages: inspection at receipt and unpacking of equipment; testing and inspection of the equipment

at completion of assembly; testing and inspection at completion of connection and prior to commissioning.

 

All tests and inspections will be coordinated with the Authority in advance for arrangement of witnesses and certification.

 

All energized equipment will be controlled via a permit system, which will be strictly enforced.  Permanent locked doors will be required on plant rooms before energizing any equipment.

 

Training

 

On site training shall be provided for the Authority personnel as set out in the specification. Discipline wise details pertaining to the scope of training shall be forwarded for approval.
