Document management and planning (Annexure B.2)

• Governs how contract documentation is managed, filed and transmitted.
• Sets the order of precedence between the referenced documents and specifications.
• Documentation is centralised, with defined access and permissions.
• The format in which documentation is transmitted is prescribed.
• A Contractor Documentation Schedule (CDS) and a Contractor Documentation Register (CDR) are used.
• The document transmittal and filing structure separates technical and administrative channels from commercial channels.
• Document metadata requirements apply to transmittals.
• Transmittals are split into contractor transmittals and employer transmittals.
• A squad check procedure applies to documents before issue.
• Appendix A contains the document transmittal workflow.

Fixed asset accounting procedure

Control objective

• Fixed assets must be fairly stated and accounted for in the correct period for additions, capital work in progress, disposals and internal transfers, maintenance and depreciation.
• Controls must identify capital assets at the time of recording, receipt or payment.

Asset recognition (IAS 16)

• Recognised when future economic benefits are probable and cost can be measured reliably.
• The Project Manager, Asset Manager and Investment Manager agree the project breakdown structure.
• The Asset Manager assesses whether the project is a qualifying asset; borrowing costs are capitalised where it is.
• Costs are processed to Capital Work in Progress and reviewed monthly by the FA Manager.
• On completion the Project Manager signs a project completion certificate.
• A Masterfile Amendment (MFA) form is completed by the Fixed Asset Controller and approved by the Fixed Asset Manager; additions above R3 million are reviewed by the Financial Reporting Manager.
• The asset is created in the Book and Tax register with an external sequential number based on the SAP asset number.
• Capital purchases run through a WBS based on the annual Capex Budget; project status is reviewed monthly so completed projects are closed.
• On MFA approval the item moves from CWIP to the Fixed Asset Register.

Cost components

• Purchase price including import duties and non-refundable purchase taxes, plus directly attributable costs: site preparation, delivery and handling, installation and assembly, professional fees, estimated dismantling and restoration, less trade discounts and rebates, and testing costs net of proceeds from items produced.
• Capitalisable: project manager and team costs, insurance, project security costs.
• Not capitalisable: opening a new facility, introducing a new product or service, doing business in a new location or with a new class of customer, administration and general overheads (stationery, meals, telephone, copy charges, courier, parking, visa applications), senior management project costs, pre-feasibility costs and training costs.
• Cost accumulates over the project and is capitalised 90 days after project completion.

Components and subsequent expenditure

• An asset is split into components where a part is significant relative to total cost and has its own useful life.
• Improvements are capitalised where they extend useful life or capacity, substantially improve output quality or substantially reduce operating costs.
• Conversions that permanently change the type or use of an asset are capitalised as a new asset.
• All other subsequent expenditure is written off to the income statement.
• Capitalised maintenance covers inspection and refurbishment such as intelligent pigging surveys, coating surveys, crack detection and repair, repair of pipeline defects, tank inspections and refurbishments, and wash-away repairs to servitudes.
• Accident repair costs are expensed; insurance recoveries are credited to miscellaneous revenue; internal labour and materials used for repairs are capitalised to the asset; replacement assets are capitalised at supplier price; unfinalised incidents at year end are provided for in full; assets damaged beyond repair are impaired to zero and derecognised.

Servitudes and foreign exchange

• Servitude rights are capitalised and depreciated over the life of the servitude and are normally included in the cost of the pipeline.
• Non-monetary foreign currency items are translated at the rate on the transaction date, or at the rate when fair value was determined where carried at fair value in a foreign currency; embedded derivatives at the forward rate at contract inception on delivery date; cash flow hedges at spot on the transaction date net of transfers to equity.

Borrowing costs

• Expensed unless directly attributable to acquiring, constructing or producing a qualifying asset, in which case they are capitalised.
• Capitalisation starts when expenditure and borrowing costs are incurred and preparation activities are in progress, is suspended during extended interruptions to active development, and stops when preparation is substantially complete.

Decommissioning

• A provision is recognised in the initial cost of the pipeline asset when it is brought into use.
• Estimated from end capping and filling of mainlines and feeder lines, removal of block valves, control valves and valve chambers, backfilling of valve chamber locations, demolition of above-ground structures, chambers, buildings, foundations and bund walls at depots, demolition of storage and other tanks, upliftment of pumps including body, motor and base plate, and rehabilitation of ground and grass at decommissioned depots.
• Includes field cost, EPCM, contingency and owner's cost, and is reviewed by the technical department.
• Calculated as the net present value of future costs over an average 75 years, inflated at a conservative rate from Transnet Group Financial Planning and discounted at the long-term government bond rate from Transnet Group Treasury.

Depreciation, useful life and residual value

• Straight-line over the estimated useful life on cost less residual amount, charged to the income statement by automatic posting, split between cost and revaluation.
• Starts when the asset is available for use, that is when commissioned or beneficial occupation is received, and stops when the asset is withdrawn from service or classified as held for sale.
• The Fixed Asset Analyst reviews the monthly depreciation calculation and reports variances to the Fixed Asset Manager.
• Useful life is reviewed annually with external valuators; significant changes are adjusted prospectively through an MFA approved by the FRM before SAP processing.
• Residual value of the Pipeline Network is zero.
• Wear and tear rates follow the Transnet Wear and Tear Policy and SARS Practice Note 19 of the Income Tax Act.

Intangible assets

• Recognised when future economic benefits are probable and cost can be measured reliably.
• Mainframe and PC software, developed or purchased, is capitalised at cost.
• General research costs are written off as incurred; development costs for assets to be tested in practice are capitalised; other development costs are written off.

Capital spares and rotables

• Spare parts and servicing equipment are usually inventory and recognised in profit and loss when consumed.
• Major spare parts and standby equipment qualify as PPE where expected to be used for more than one period or usable only with an item of PPE.
• Items stay in the Capital Spares class until used, then transfer to the asset at net book value, taking the lower of the remaining useful life of the main asset and the economic life of the spare; an MFA approved by Head Office is required before SAP adjustments.

Retirements and transfers

• An asset is withdrawn from the Asset Register on transfer or on disposal or scrapping.
• Transfers are at carrying value, transferring cost and accumulated depreciation or wear and tear, and are accounted for in the same accounting month by both entities.

Physical security and verification of fixed assets

Objective

• Fixed assets are physically secured against unauthorised access and theft.
• The Depot Manager safeguards the organisation's assets; the Fixed Assets Manager ensures periodic verification and reconciliation to the fixed asset register.
• Above-ground pipeline assets are verified annually by the Depot Manager and every three years at selected sites by the valuator.
• Other movable items and inventory-controlled pools are verified annually by December.
• Verification confirms the accuracy, validity and completeness of property, plant and equipment recorded in the Fixed Assets Register.

Pre-verification

• The Assets Department sends the asset register to the relevant Depot Managers.
• The Depot Manager appoints a technically competent verifier to identify assets against the register.
• The verifier checks the asset number on the register against the physical asset and ticks agreeing items.
• Assets present but no longer used are marked obsolete, confirmed by the Depot Manager and separated from workable assets.
• The Depot Manager spot-checks the verification and signs off the register before it goes to the Assets Department.
• The Assets Department test-checks selected depots and makes amendments for variances.

General procedures

• Every asset is physically checked, counted and compared with the Fixed Asset Register report.
• Verified assets are tagged with a sticker.
• The count runs from the register to the ground and back.
• Discrepancies are recorded on separate working papers.

Completion

• The register and completed schedules are signed by the count team and verified by the Depot Manager.
• A summary signed by the Depot Manager goes to the Fixed Assets Analyst at Head Office.
• The Fixed Asset Analyst investigates discrepancies, documents explanations and corrective steps, and corrections follow the fixed assets policy, for example authorisation of disposals and scrapping and write back of assets found on the ground but not in the register.

Tagging

• The fixed asset controller lists capitalised assets monthly and sends the list to the project manager or end users for tagging.
• Cost centre managers are accountable for assets under their cost centres being tagged and traceable to the register.
• End users or cost centre managers print tags with the asset number or a unique identifier and affix them to the asset body.
• Where an asset cannot be tagged, a unique identifier traces it to the register; an MFA signed and approved by the Fixed Asset Manager or FRM is required before system changes.

The project involves the engineering, procurement and construction of a fire system upgrade at the Transnet Pipelines Howick Depot in KwaZulu-Natal. The new fire water infrastructure comprises a pumphouse, new water tanks, new valve banks, and an elevated pipe network. The geotechnical investigation was undertaken to ascertain ground conditions and recommend a suitable founding regime. The site is a National Keypoint with strict access control, roughly trapezoidal, about 2.4 ha, with a gentle fall to the south east. The earmarked area for the new fire pump room and water storage tank is at the eastern extremity near the main entrance. The site is underlain by sedimentary rocks of the Volksrust Formation, Ecca Group, Karoo Supergroup, with residual clay and silt rich soils. The report includes fieldwork methods, soil profiles, dynamic cone penetrometer tests, geotechnical assessment, earthworks, re-use potential, founding recommendations, and stormwater drainage.
