rhi's project cost information and experienced personnel, supported by market- leading systems and processes, enables us to provide strategic advice and data management for our clients.

We are actively engaged in providing solutions for our clients, specialising in the preparation and evaluation of tender documentation for competitive bidding. Examples include: the re-measure of AFC / as-built drawings, effective cost reporting, monitoring and forecasting throughout the duration of the project; and establishing the validity, negotiating and agreeing the value of variation requests and claims.


  • Supports early decision-making
  • Enhanced cost and schedule assurance
  • Benchmarked cost analysis against comparable projects
  • Mitigation of commercial risks
  • Effective cost control performance


We are market leaders in quantity surveying technology.

Our rhiCOMS™ unit rate contracting estimating and support software is a bill of quantities and schedule of rates system.  This system is supported by the benchmarking utility of rhiDATA.

Over the last 30 years, rhiCOMS has been used in more than 100 fabrication projects and numerous onshore construction projects globally. rhi engages the market with a contract format and reimbursement methods that reduce risk and uncertainty for all parties involved in the process.

Our broad experience ranges from small life extension projects through to asset development programmes. The management of standard models provides access to relevant benchmarking and evaluation data, building clients’ confidence in the outcomes.

Our systems and processes have evolved to reflect our clients’ requirements and the need for innovation and efficiency. These established processes mitigate risk through data-led decision-making and deliver cost efficiencies through the application of our technology.


  • Established system and process reducing schedule risk for tendering
  • Familiarity of the international contracting market with the processes to optimise cost
  • Efficiency through automation reduces cost of services and makes time available to engage with the underlying challenges of project changes and control
  • Access to current and relevant historic data helps to build confidence
  • Firm basis for pricing manages change and reduces uncertainty

How can rhi support a project during the early Concept, Pre-FEED, & FEED stages?

rhi provides independent estimating to support the early project stages. Our estimating and benchmarking approach, coupled with our in-depth reference data, are actively managed in-house to support changing market conditions and differing geographical locations.  Provision of a robust estimate basis to support critical project stages, in particular project sanction.

How do I know my project cost is competitive with similar projects?

Our vast experience with clients around the global means access to current and historic project data that provides benchmarking insight and assurance. As a client, you will be informed on value and efficiency relative to similar projects, supported by a range of the most relevant benchmarking charts. allowing you to make informed decisions.

How do I ensure that my EPC cost estimates are reasonable, reflect the scope of work and are a sound basis for FID approval?

rhi has over 30 years’ experience with estimating the costs, quantities and manhours of complex oil and gas projects around the world. Our in-house estimating tools enable our estimators to prepare Classes 1-5 estimates covering onshore, offshore, subsea, drilling and wells activity sets. This allows us to develop check estimates and comparative analyses of study contractors and EPC contractor estimates.  Project teams can have increased confidence that study / EPC estimates are robust, reflect the likely outturn scope, indicate regional political requirements and sector market trends.

How can I kick-off my tendering process early without waiting for detailed scope and increasing the risk losing control of the scope / costs during execute?

Our rhiCOMS database enables us to pre-load a library of materials and activities that accurately reflect those required for your project, enabling tenderers to price their submission based on these quantities. You can achieve an early award of contract and accelerate your construction start, with the added benefit of having a priced detailed schedule of rates to allow changes on the same basis as the tender.

How do I organise the tender process to ensure all bidders receive the same information and respond in a consistent manner that makes tender evaluation possible on an “apples for apples” basis?

Our market-leading rhiCOMS unit rate tender evaluation tool enables us to pre-load the library of materials and activities required for your project and have tenders’ access and price their submission based on these quantities.  You have a secure, consistent process which is proven in the industry and is known to all the major engineering and fabrication contractors.

How to improve cost efficiency across the life cycle?

We can improve cost efficiency through:

Competitive Price – Input to Selection of Appropriate Contract Strategy; Ensuring well defined scope for Tenderers; Effective Tendering Process; Mechanism to Manage Change; Benchmarking.

How can I take a single source approach due to time considerations and still demonstrate value?

Our knowledge of engineers and fabricators in global markets supports our clients’ selection of a preferred contractor. rhi’s extensive library of information allows us to provide bid check estimates to compare to the estimate provided by the sole source contractor.

Project teams will have increased confidence in their selection of a sole source contractor and be able to identify areas where the contractor has priced high in comparison with industry standards which will enable negotiation.
