Matla Power Station requires additional horizontal filter drains and new vibrating wire piezometers at its Ash Dam Facility to improve dam stability. The drains relieve the phreatic surface; the piezometers provide real-time phreatic level and safety factor data. Work is phased: a 12-drain pilot is monitored for a month before the Employer decides on the remaining 48 drains. The contractor carries the drainage design and all temporary works design, signed off by an ECSA-registered engineer.

Scope — Matla Power Station Ash Dam Facility

• Install additional horizontal filter drains and supply and install vibrating wire piezometers to improve ash dam stability.
• Drain positions to be agreed between the contractor and the Employer.
• Contractor must design the drainage system for the Matla Ash Dam Facility; drawings must be signed by an ECSA-registered Pr Civil Engineer.
• Pilot phase: 12 drains, each at least 50 m long, at the toe and the first bench (1563 mamsl), sited between piezometer line 2 and line 10 at 20 m spacing.
• Pilot drains are monitored for one month; the Employer then decides whether the remaining 48 drains proceed.
• Remaining drains installed in phases, with the most critical areas first.
• Waste from drain installation disposed of at a location the Employer nominates.

Drain construction

• 110 mm diameter perforated HDPE pipe with a factory-fitted geotextile filter surround, installed horizontally at a minimum 3° slope for gravity flow.
• Toe drains discharge into the existing solution trench through a 110 mm unperforated HDPE outlet pipe.
• Bench drains discharge into a drainage collection system.
• Collection system: 160 mm diameter perforated HDPE collector pipe with downpipes carrying water to the existing solution trench without recharging the phreatic surface.
• Rodding eyes: 110 mm Y-junctions at the end of each drain outlet pipe and at the end of each collector pipe.
• Geotextile: A4 Bidim or similar approved product, selected against the FHWA (1992) Drainable Pavement Systems criteria — soil retention, permeability, clogging resistance and durability.

Installation method

• Horizontal directional drilling to the required length.
• Temporary casing inserted as drilling progresses to prevent the hole collapsing.
• Drill head withdrawn, drainage pipe with geotextile surround inserted, casing withdrawn, outlet end plugged.
• Collection system then installed to take the discharge.

Piezometers

• Four sets of four automated electronic piezometers, one set on each of the four benches, with vibrating wire tips hydraulically pushed to the required depth.
• Tip depths for each of the four sections set from the CPTu results in geotechnical report MG23/195/rev.03.
• System must include a data logger, wireless gateway/router, configuration, application software, network management software, data management software and hardware (portable/mobile workstation); web-based.
• Data logger must transmit a radio signal over an open field range of 10 km.
• Contractor, together with the Eskom electrical system engineer, must identify the nearest power point and carry out the modifications needed to power the piezometers, including cabling and protection.
• Submit all schematic diagrams, cable schedules, cable block diagrams and single lines.
• Specific locations per the appendix.

Design responsibility

• Contractor designs all temporary works required for the works.
• All designs, design reports and construction drawings signed off by an ECSA professionally registered technologist or engineer carrying full professional accountability.

Matla Power Station requires a civil engineering contractor to refurbish the gravel roads at the New and Old Ash Dam within its ash dam facility.

Background

• The ash dam roads were never designed as gravel roads but have been in service for many years.
• Periodic grading has progressively lowered the road surface below natural ground level, so water collects and forms ponds.
• Water, mud and slippery conditions make vehicle movement and inspections difficult.

Scope

• Requirements and specifications for repairing the New and Old Ash Dam gravel roads.
• Work includes, but is not limited to, grading of the access roads, blading and re-gravelling.

Purpose of the evaluation strategy

• Defines the mandatory criteria, the qualitative criteria and the responsibilities of the Tender Evaluation Team.
• Once authorised, the criteria cannot be changed without further authorisation.

Governing references

• 240-48929482 Tender Technical Evaluation Procedure.
• 240-53716726 Technical Scoring Form.
• 240-53716712 Technical Evaluation Results.
• MEA-06593 scope document for the gravel road repair.

This document sets the technical evaluation rules only; it does not set out the bid submission channel, address or returnable-form pack.

Mandatory document to accompany the bid

• Valid CIDB Grade 7 CE certificate — without it the submission is invalid.

Supporting evidence required for scoring

• Three executed project references with completion certificates (road construction, gravel road repair, road maintenance).
• Detailed method statement covering the eighteen technical points listed under the functionality criteria.
• ECSA registration certificate plus CV for the professionally registered Civil Engineer.
• Proof of ownership or lease agreements for every plant item claimed.

Evaluation stages, in order

1. Mandatory technical requirements — pass/fail.
2. Functionality (qualitative technical criteria) — weighted 100%.
3. Price.
4. Objective criteria (SHE and SD&L requirements).

Minimum qualifying score

• Functionality threshold: 70% of the weighted final technical score. Bids below 70% are not considered further.
• Only the civil discipline is assessed; the technical criteria are civil-specific.

Functionality sub-criteria and weights

• Detailed method statement: 40%.
• Three traceable executed project references: 30%.
• ECSA-registered Civil Engineer with 6–10 years road construction and maintenance experience: 15%.
• Proof of ownership or lease of listed plant: 15%.

Method statement scoring (18 technical points)

• 1 to 3 points addressed: 0%.
• 4 to 8 points addressed: 40%.
• 9 to 14 points addressed: 80%.
• 15 to 18 points addressed: 100%.

Project reference scoring

• No verifiable and traceable evidence: 0%.
• One of the three activities evidenced: 40%.
• Two of the three activities evidenced: 80%.
• All three activities evidenced: 100%.

ECSA engineer scoring

• Under 6 years: 0%.
• 6 to 7 years: 40%.

Scope of work

• Refurbishment of the gravel access roads serving the New and Old Ash Dams at Matla Power Station's ash dam facility.
• Activities include grading, blading and re-gravelling of the New and Old Ash Dam access roads.
• The existing roads were not built as engineered gravel roads; repeated grading has cut them below natural ground level, so water ponds form and the surface becomes muddy and slippery for vehicles and inspection teams.

Technical outcomes the method statement must address

• Inspection and measurement of material quantities to be imported.
• Sub-grade: in-situ material ripped or scarified to 150 mm depth and compacted to 93% Mod AASHTO density; imported material from a suitable commercial source where required.
• Wearing course: material imported from a suitable commercial source.
• Compaction to 95% Mod AASHTO at a minimum thickness of 150 mm.
• Minimum wearing material size specified.
• Final graded road oversize index below 5%.
• CBR of at least 15 at 95% Mod AASHTO at optimum moisture content.
• Drainage collection system.
• Traffic control and management.
• Schedule of quality checks.
• Dust control.
• Test steps, stages and minimum requirements for each test.
• Expected performance of the finished road for both light and heavy vehicles.
• Minimum life span of the finished product.

Company experience

• Three traceable executed projects must be evidenced, each supported by a completion certificate.
• The three activities to be covered are: previous road construction experience, gravel road repair experience, and road maintenance experience.
• Scoring: none evidenced 0%; one activity 40%; two activities 80%; all three activities 100%. Weighting 30%.

Key personnel
