MTL has helped companies across a range of industries overcome major technical challenges and build productive new resources in the most cost-effective way.

Project management skills are a key part of the package we offer. As well as providing mechanical engineering expertise to the highest
international standards, we will also work closely with associated companies to provide electrical, civil and automation capabilities. It’s a partnership approach that lets us draw on the most appropriate technical skills, to the ultimate benefit of our clients.

The process starts from the first day MTL is called in to discuss a project. We will ensure a meeting is set up to agree on the scope, timetable, deliverables and budgets. We also take responsibility for putting together the project team, engaging specialist consultants, and making sure the team delivers. Regular meetings and weekly or monthly reports complete the picture.

Our projects managers, while having technical backgrounds, are also aware of the commercial, health, safety and environmental considerations that need to be managed to successfully deliver a project. This allows them to develop and manage solutions to meet Client drivers.

We are experienced in developing implementation plans, scheduling projects, management of procurement, preparation and administration of construction contracts (NEC3, FIDIC, NZS3910), risk assessment and management.

MTL has a specialist team of designers who are experienced in developing detailed engineering drawings.

Typical Design Stages & Deliverables Include:

Investigation: Process Flow Diagram, (PFD) & General Arrangements/ Elevations to include proposed location of main equipment & piping.

Preliminary Design: PFD, Piping & Instrumentation Diagram (P&ID), General Arrangements/Elevations to include location of main equipment & piping, Vessel Datasheets & 3D Model of proposed configuration for client project design review.

Detail Design: Tender & Construction Issue, PFD, P&ID, General Arrangements/Elevations & Piping, Vessel Datasheets, Piping Isometrics & 3D Model of final configuration for client project design signoff.

As Built: As built Construction drawings (Formatted to clients drafting requirements) including Laser Scan images from brown field sites.

MTL Design Tools

Drafting packages include: Plant 3D (P&ID & 3D Plant/Piping), Autodesk Inventor, Revit and Navisworks Design Review Software.

AutoCAD Plant 3D software allows integrated functionality of data consistency between P&IDs and 3D plant design models. The 3D
plant model improves accuracy and enhances coordination between other discipline/services. Client design reviews can be undertaken in a 3D environment utilising Navisworks software. Typical drawing deliverables in 2D format – PFD, P&ID’s, plant layouts and spec driven piping isometrics. Additional information such as material take-offs and engineering lists can be exported to MS Excel directly from the Plant 3D software.

3D laser scanned images can be imported from point cloud which is a very cost effective method of as-building a complex brown field site. Where required existing interface points, equipment & structures can be modelled from the point clouds data, obsolete equipment & structures can be removed. The increase in accuracy of the as-built information and the use of clash detection in the Navisworks software between other disciplines/services/existing infrastructures can help reduce the amount of onsite fabrication.

Autodesk Inventor is a 3D parametric mechanical design software used for design of complex mechanical structures, process equipment, pressure vessels & storage tanks.

Navisworks is a 3D project review software with real time views and sections. Clash detection facility on multi disciplines projects.


MTL’s Health & Safety Management System is comprehensive and is designed to be adapted for use in engineering services engagements for design, construction, commissioning and/or operations & maintenance support projects.

MTL adopts an ‘industry best practice’ approach and continuous improvement process for its Health & Safety Management system. MTL holds Impac PREQUAL Contractor Prequalification Level 5 for Category 3 Engineering Services. MTL is a member of SiteSafe NZ Ltd.

As part of our Health & Safety Management System, all new staff undergo a Health & Safety Induction, attend site inductions and receive regular site specific / generic safety training as required. We utilise hazard assessment systems appropriate for the scope of work (hazard register or task specific JSEAs with supporting methodologies), with emphasis on near miss/incident reporting and tracking of H&S KPIs.

Our sub-consultant agreements reference MTL & Client Health & Safety Management Systems including prequalification requirements as appropriate. Our sub-contractor agreements reference MTL & Client H&S System requirements including Prequalification requirements and recommend use of Site Safe NZ’s Site Specific Safety Plan documentation if appropriate.

Site safety audits are completed at regular intervals to ensure sub consultants and /or contractors comply with legislation and Principal safety requirements. Our monthly project reports record site H&S statistics including working hours, training, incidents & accidents and we can produce reports on fatigue & fitness for work, incident & hazard management, and inspections.

MTL’s current HS&E KPI statistics, Impac PREQUAL Contractor Pre-qualification certification and audit reports can be provided on request.

PREQUAL has been specifically established to address industry concerns with contractor prequalification. PREQUAL combines the experience and track record of some of New Zealand’s leading Health & Safety Practitioners with freshly-developed business processes that provide fast, efficient and cost effective pan industry contractor prequalification service for Clients and Contractors. This has been benchmarked against both international best practice and local experience (The Impac PREQUAL model has been developed with reference to a range of multinational contractor prequalification processes in BHP, Rio Tinto, Construction Line, CHAS, and the Federal Safety Commissioner, as well as the experience of local Client organisations). Our clients that utilise PREQUAL include Mercury NZ Ltd, Genesis Energy Ltd, Contact Energy Ltd, Trustpower, Fonterra, Meridian & Carter Holt Harvey.
