Home / Construction cost and valuation guide
A practical guide · Bhutan
Understand the language behind a building budget, contractor offer or property valuation. These plain-language explanations connect common questions to Omeya’s services and research.
The precise meaning of a term depends on the instruction, contract or standard being used. Start with the decision you need to make, then agree the scope and evidence.
Quantity surveying connects the scope, measurement and commercial management of construction work with its cost. The agreed service may cover early budgets, bills of quantities, tenders, changes or final accounts.
Explore this topicA cost plan organises an estimated budget around an agreed design and scope. It provides a basis for reviewing affordability as the design develops.
Explore this topicAn estimate forecasts the cost of defined work using the information available at a stated stage and pricing date. Its assumptions, allowances and exclusions explain how the total should be used.
Explore this topicA BOQ describes measured construction work in items that can be priced. It gives contractors a common basis for tendering and helps explain differences between offers.
Explore this topicThe BSR is a published reference for construction rates in Bhutan. The edition, units, scope and project conditions need to be understood before a rate is used in an estimate.
Explore this topicA rate build-up records the components and assumptions behind an item price, such as labour, materials, plant and relevant allowances. It helps a reviewer understand why a rate is appropriate for the work.
Explore this topicPlinth area is a building-area measure used in cost information, including the BSR Quick Cost Guide. Always check the measurement basis and units: a rate using area and height cannot be applied as a simple area-only price.
Explore this topicTender comparison checks offers against the same requirements. Quantities, exclusions, provisional allowances and commercial terms can explain why headline prices differ.
Explore this topicA contingency allowance addresses identified uncertainty in a budget. Its basis should be explained and reviewed as the design and project information develop.
Explore this topicA provisional allowance provides for work or cost that is not yet fully defined. The contract and pricing documents determine how that allowance is described, instructed and adjusted.
Explore this topicA variation is a change dealt with under the relevant contract arrangements. Its cost effect depends on the instructed work, contractual basis and supporting records.
Explore this topicThe final account records the agreed financial outcome under the contract. Clear records of original scope, changes and adjustments help the parties understand the final amount.
Explore this topicA cost overrun is a cost outcome above the budget or estimate used for comparison. The comparison needs a clear baseline and scope, particularly where additional work has been approved.
Explore this topicReal estate valuation considers the value of a specified interest in land or property for an agreed purpose and date. In Bhutan, Omeya scopes land, building and hotel valuation advice against the evidence and professional responsibility required.
Explore this topicAn asking price states what a seller seeks. A market-value opinion requires an agreed basis and relevant evidence; it cannot be established from an asking price or building cost alone.
Explore this topicReplacement cost concerns the cost of replacing an asset or defined building provision. It answers a different question from the market value of the property interest.
Explore this topicA valuation date fixes the point in time to which the value opinion relates. Market conditions and available evidence may differ at another date.
Explore this topicThe purpose explains why a valuation is commissioned and who may rely on it. Lending, a potential transaction and an internal asset review can require different instructions and reporting.
Explore this topicThe MSc research discussed on this website considers how international approaches could be introduced through local training and evaluated pilot projects. It describes a proposal, rather than an adopted national implementation programme.
Explore this topicNRM provides measurement rules and guidance for construction cost management. A consistent structure still needs suitable project information, local cost evidence and professional judgement.
Explore this topicICMS provides an international framework for classifying and reporting construction costs and related life-cycle information. It supports a common reporting language; the applicable framework and edition should be confirmed for the instruction.
