1.12 At the end of the project, ADMA-OPCO/Engineering Services Department shall
receive from the Contractor through the Project Team Leader the following
deliverables; for retention as future technical references:a.
b.
c.
d.
A master set and a copy of the ”Project Completion Manuals &
Documents”.
Two sets of the final As-Built CAD drawings and schedules stores on two
separate sets of 8mm, 2.3 GB tapes and one set of high quality reproducibles
(polyester sheets) of the drawings produced manually.
For documentary purposes, a set of good quality 35mm negatives (silver
coated) on Aperture Cards (originals not duplicards) is required.
Specifications to be in accordance with DOP 10.2.3 and 10.2.4. The cards
should be stamped with the Contractor’s seal.
A copy of DOP previously submitted to the Engineering Consultant.
NOTE: Existing CAD System
Existing ADMA-OPCO CAD system uses Sun Sparc workstations running Autocad release
12 on Solaris 1.1 (Sun 0S4.x) operating system. PRO-Pipe 12/11.1 and PRO-Flow 11.1 are
used for piping and P&ID’s or latest version of Autocad.
The CAD Drawings received from the Contractor shall be fully compatible with ADMAOPCO CAD System.
2.
Records Format
In addition to hard copies of Contractor documents and manuals, the Contractor may also
offer to provide this information in a format suitable for electronic viewing and
reproduction.
Formats acceptable to ADMA-OPCO are as follows:Software:
Word Processor:
Documents/Manuals should be produced using MS Word latest Version.
Calculation Sheets:
Calculation Sheets should be produced using MS Excel latest Version and or
mathcad sheets be produced using latest version of software.
Media:

Date
Embedded Drawings/Sketches:
Within Manuals/documents should be produced using Autocad Version 12.
The above information should be supplied to ADMA-OPCO preferably on
CD-ROM format. Alternatively 3.5” HDD Diskette can be accepted. In
either case, a comprehensive menu index shall be included.

100%
Classification of steel members are defined in section 3 of this specification.
Applies to all welds other than butt welds (such as T, K or Y-joints, tubular
joints) having full penetration, or partial penetration with weld metal crosssection exceeding 12.7mm (1/2”).
Magnetic particle testing may be replaced by liquid penetrant testing with prior
approval of ADMA-OPCO.

(6)
Ultrasonic testing applies when material thickness is more than 12.7 mm
(1/2”). Ultrasonics may be replaced by radiography where wall thickness is
less than or equal to 30 mm.
(7)
Radiography is normally replaced by ultrasonics for thickness > 30 mm.
Radiography applies by priority to intersections of butt welds and to start and
stop points of automatically welded beams.
(8)
100% of extent for radiography (WT 40mm) or ultrasonics (WT > 40 mm)
of:
Flanges of main beams and columns
Circular welds of main tubulars.
(9)
If defect rate in the inspected welds which are not 100% tested (i.e. by
radiography, ultrasonics, magnetic particle) exceeds 10%, the remaining welds
shall be 100 % NDT tested at the main CONTRACTOR’s expenses.
(10) Magnetic particle to 100% extent only when welding on semi-hard or hard
steels and alloy-steels liable to quenching under welding operation (for
instance welding of bearing plate). Purpose of inspection mainly to ensure
freedom of cracks, excessive undercuts or other injurious notch defects.
