Project Management

Our mission is to help you get the best return on your capital investment. We will help you select the right projects and implement them correctly from the start. With our project control focus, we ensure tight alignment with your business case. We do this by establishing and controlling the right baselines for project scope, schedule, risk, and cost. We place an emphasis on front-end loading which ensures the selected baselines are optimal and predictable given your business drivers. 

Earned Value Analysis or Earned Value Management (EVM Analysis) is an essential part of project management. The methodology allows our project managers to measure the amount of work done by the team members and evaluate the value of that work. The analysis is made beyond the fundamental review of the cost and scheduled reports of the project management. It helps our managers to get a deep insight into the intensity of the progress that has been achieved. 

Change management is an important factor of HPS Project Management capability. With inflationary pressures, such as increases in material costs on EPC projects, the need for a robust change management process to deliver to cost and schedule has never been greater. There's no "one-size-fits-all" approach to change management – so there's no perfect way to lead it but to apply a set of principles to each project taking into account the stage of the project in its lifecycle. 


Piping & Layout

HPS has a diverse team of mechanical and piping engineers and designers consistently producing innovative, robust and cost effective plant design solutions.

The layout group collaborates with client engineers, plant operators and other engineering disciplines utilising 3D Modelling tools to provide a fully coordinated plant design. Visual review tools allow all stakeholders to regularly review and input to the design through its development.

HPS constantly strives to embrace technologies which add value and accuracy to the design process and provide bridges between the design disciplines, suppliers and installation contractors.

Our Piping services include:

  • Option studies

  • Feasibility study – conceptual design

  • FEED study – basic engineering

  • Engineering design – for procurement

  • Detailed design – for construction

  • Construction supervision and support

  • Existing Plant Survey

∙ Traditional site measure

∙ Laser scan and post processing

∙ Topographical survey

∙ Specialist surveys such as drainage & GPR

∙ As-built layouts

∙ As-built P&IDs – both graphical and "intelligent" with embedded plant data

Our Piping deliverables include:

  • 3D coordinated plant model

  • Pipe, valve, line item, insulation and associated specifications

  • Plot plans

  • Plant layouts – equipment location GA drawings

  • Piping arrangement drawings

  • Pipe support, location, details & schedules

  • Piping isometric drawings

  • Bulk and individual line material take-off

  • Miscellaneous mechanical details

  • Mechanical procurement packs

  • Installation specifications

  • Vendor bid analysis
