Frequently Asked Questions.

We deliver six core services: civils, volume calculations, diagrams & plans, rehabilitation, urban development and drone surveys. We also coordinate capital project delivery alongside national contractors and parastatals.

Yes. For projects like the Makoti Flats 56-unit high-rise we delivered start-to-finish — from setting out, foundations and superstructure through to handover and as-built documentation.

Setting out, excavations, foundations, plinths, columns, superstructure, platforms, parking lots, roads, engineering fill, precision work and wet works.

Yes. We've supplied 10 000+ m³ of high-strength ready-mixed concrete for Transnet's Saaiwater works in Mpumalanga. Bulk supply with on-site quality control is a regular service.

Yes — including asphalt milling, rolling, drainage redesign, condition reports and compaction. We rehabilitated port roads at Maydon Wharf Berth 15 in 2025.

Sewage systems, stormwater drainage, internal services, layered services installation, township establishment support and access roads.

Yes — drawing up of plans & diagrams, revisions, as-built documentation and coordination across architectural, structural and services disciplines.

Yes. We've delivered 60–100 sectional 30 m high-mast poles to Richards Bay Naval Base, plus 15+ outdoor 1 250 A 25 kV high-voltage circuit breakers to Bayhead, Durban.

Both. Our portfolio includes mixed-use development (Newtown Junction), residential high-rise (Makoti Flats), and parastatal infrastructure (Transnet, Richards Bay).

Yes — we've worked alongside national contractors like WBHO on dedicated brickwork or civils packages with teams of 60–100 on site.

Submit our online form on the Free Consultation page or email admin@blackmahoganycivils.co.za. We respond within one working day.

Yes. Initial consultations and indicative quotes are always free. Detailed estimates that require site visits or design work are quoted as scoping engagements.

For straightforward briefs, 2–5 working days. For complex capital projects requiring site assessment, 7–14 working days.

Project location, scope, available drawings or specifications, target start date, and any constraints (budget envelope, programme deadlines, parastatal requirements).

Yes for well-scoped works. For projects with unknowns we offer remeasureable rates with capped totals or cost-plus arrangements as appropriate.

Standard terms are progress payments tied to JBCC or NEC milestone certificates. We accept EFT and bank transfers.

Project-dependent. Mobilisation deposits are standard for civils and capital works to cover plant, materials and crew commitments.

For sites within our home regions (Johannesburg, Pretoria, Durban) — typically yes. For remote sites, mobilisation is itemised separately.

No. Our quotations itemise materials, labour, plant, transport, supervision and contingencies. Variations are agreed in writing before work proceeds.

Through a formal variation order — priced, signed and dated before any change is implemented on site.

Brief intake → site assessment → quotation → contract → mobilisation → execution → progress reporting → handover with as-built documentation.

Typical mobilisation is 2–4 weeks after contract signing, depending on plant availability and scope size.

Yes. Every project is assigned a dedicated project manager who coordinates communication, reporting and decisions throughout delivery.

Weekly written progress reports plus bi-weekly site meetings. Drone-based progress imagery is available on capital projects.

Yes — coordinated through your project manager and subject to site induction and PPE.

Joint inspection, snag list resolution, full as-built documentation pack (drawings, volume calcs, test results, certificates), and a defects-liability period commences.

Yes — we contract under JBCC, NEC3/NEC4, GCC and FIDIC frameworks. We also accept private bespoke contracts.

Yes. We integrate with appointed consultants and follow their drawings and specifications.

Front-loaded planning, Monte Carlo schedule analysis on critical-path activities, weekly look-ahead reviews and pre-agreed acceleration measures.

Highly project-dependent. A residential high-rise like Makoti Flats took ~14 months. A road rehabilitation package can be 6–12 weeks. We commit to written milestones.

Yes — including excavators, rollers, asphalt milling machines and concrete pumps. Specialist plant is hired in for short campaigns.

Project-dependent. We've fielded teams from 10 to 100 — peak head-count was 100 on the Newtown Junction brickwork package.

100% qualified. We work exclusively with skilled engineers, surveyors, and technicians who meet our standards — no shortcuts on team selection.

Mostly self-perform on civils, brickwork, surveying and concrete. Specialist trades like MEP, lifts and high-voltage installation are sub-contracted to vetted partners.

ITPs (Inspection & Test Plans) per work package, daily site quality checks, third-party material testing, and weekly QA review meetings.

Standard strengths from 15 MPa to 60 MPa. High-strength designs available for capital infrastructure. Cube-tested in accordance with SANS standards.

Yes — for time-critical works like port operations or live road rehabilitation, we run 12-hour or 24-hour shifts with appropriate supervision.

Yes — both. Precision setting-out, finishing, and water-resistant concrete works are core capabilities.

Yes — we delivered 81 parking bays at Makoti Flats and routinely build access roads as part of urban developments.

Engineering fill, layered works, and bulk excavation are everyday capabilities — backed by drone-derived volume calculations.

Yes — fully compliant with the Occupational Health and Safety Act (Act 85 of 1993) and Construction Regulations 2014.

Yes — site-specific HSE plans, risk assessments, method statements and emergency procedures are produced for every project.

Zero LTI on capital projects since inception. Detailed safety statistics are available on request under NDA.

Yes — every worker, sub-contractor and visitor receives a documented site-specific induction before access.

Yes — we hold valid CIDB registration in relevant grading classes for civils and building works. Grading certificates available on request.

Weekly is standard on capital projects. Daily flights are possible for time-critical operations subject to airspace clearance.

Yes — stockpile, excavation and fill volumes computed from photogrammetric models with delivered reports.

Yes — pre-construction baseline, in-progress comparisons, and post-construction as-built captures are routine.
