This shall be included in material receiving inspection procedure and to be recorded in Quality Control Material Receiving Inspection Report form, which is to be reported immediately to company if non- compliance be found against the materials. Lightings, devices and controls shall comply with SAES-P-123.
Explosion proof identification to the specific material shall be verified with stipulating certifications (if any) as per requirements depending on the intensive usage of the material according to the drawing, as well as area classification.
Survey the location of lightings with reference to layout drawings and details as well as in the given company Technical Scope of Work. Identify area classifications to include hazardous areas in accordance with the latest Approved for Construction drawing.
Categorize and select lighting fittings, devices, junction boxes and related materials to include wattage, types of fixtures/devices/junction boxes, and type of mounting in accordance to the company latest approved construction drawing and details, as well as with area classification requirements.
Check that mounting heights are in accordance with the elevations shown on the plan and detail drawings as per C Technical Scope and Saudi Aramco Standards.
Where manufacturer’s instructions are furnished with the lighting fittings and devices, installation detail shall conform to the requirement.
Install necessary supports and poles as per detail drawings given, and to the installation standards in accordance with the Project specification and drawing. Ensure that the support is suitable to the lightings/devices materials in consideration to the various environmental classifications stated in layout drawings.
Lighting fittings including lamps, covers, guards and diffusers shall be handled with care to avoid breakage or damage to the fragile parts.
Check the proper position when bringing the fixture to its location and verify also that overhead clearance, working radius and path are clear from any protruded materials or obstruction.
Mount the lighting fixture and devices in the position, elevation and location as shown on project Approved for Construction drawings. Location may be varied slightly to avoid piping or structural
The elevation, level and vertical alignment of the lighting fixtures and devices shall be checked ensuring that it is securely and rigidly fixed in place.
Lighting unit orientation shall be verified ensuring illumination in the area is sufficient and not obstructed by pipes or structures.
Ensure that the conduit to which lighting fittings, devices, and junction boxes were attached are fixed by substantial screws so that the weight of the installed lighting fittings, devices and junction boxes will not be carried by the conduit.
Install conduit per size indicated on drawing details, conduit layout. The conduit shall be cut square, with ends reamed and where applicable, with sharp and clean cut threads. Apply appropriate thread lubricant for conduit joints connections and put rubber or metallic bushing on conduit ends. Field cut threads and threads cleaned at site on galvanized conduit shall be touched up with cold galvanizing compound, approved by Saudi Aramco.
Conduit shall be securely fastened within 900 mm (3ft) of each outlet box, junction box, device box, cabinet, conduit body, or other conduit termination.
After installation following the complete drawing and details, clean the lamps, reflectors, diffusers and housing body. Dust and dirt shall be removed by using appropriate rags.
Terminate all wiring or cable connections according to the termination schedule, installing all termination requirements including identifications required, in which non-corroding material with cable reference numbers, as noted in the cable schedule, are clearly visible. Cabling and wiring works shall be done as per SAES-P-104.
Double check all wiring and circuit connections for the lightings/ devices with respect to circuit diagram to avoid possible short-circuiting and damage.

RECEPTACLE OUTLET INSTALLATION

Verify the material specification to its conformance with the classification area requirements especially to hazardous areas.
Receptacles in indoor and outdoor, electrically classified areas shall be approved for these locations and shall be industrial specification grade.
Survey the location of receptacle with reference to layout drawings and details. Identify area classifications to include hazardous areas in accordance with the latest Approved for Construction drawing.
Check that mounting heights are in accordance with the elevations shown on the plan and detail drawings as per Saudi Aramco Standards.
Receptacles shall be mounted in boxes or assemblies designed for the purpose, and such boxes or assemblies shall be securely fastened in place as per Project Specification and Detail drawings.
For the measurements for receptacle to receptacle & height in Building, UPS/ELEC and Battery Room shall refer to project specification and detail IFC drawings.
Terminate all wiring or cable connections according to the termination schedule, installing all termination requirements including identifications required, in which non-corroding material with cable reference numbers, as noted in the cable schedule, are clearly visible. Cabling and wiring works shall be done as per SAES-P-104.

TESTING OF LIGHTINGS, AND RECEPTACLE

QC inspection for completed lightings, devices, and supports shall be requested, and inspection/test results shall be filed and recorded on appropriate approved forms.
Visual inspection shall include dimensional check for junction box, support inspection and location verification which shall be recorded to the approved forms.
Conduct preliminary testing prior to final inspection ensuring that all connections and functions are appropriate with respect to wiring diagrams and other requirements.
Final illumination and functional test shall be conducted and all results shall be recorded as per SAIC and SATR forms.
All inspections and testing activities shall be referred to SATIP-P-123-01 complying with all the requirements. QC Inspector shall witness and record the result and shall be submitted to company.
Documentation of the whole system after completion shall be completed as required, which shall be submitted to company then for review and approval of documents.
