01 / OUR PERSPECTIVE

Expertise and judgement

Sound advice begins with an understanding of the project.

The value of our advice rests on
understanding the project and exercising judgement.

Founded in 2021, Chenyi specialises in construction cost consultancy throughout the project lifecycle. We examine project conditions, design options, contractual responsibilities and implementation records, providing advice with a clear basis and scope of application.

Experience in valuations, variations and final account reviews informs our work on subsequent projects. AI assists with organising documents, comparing data and finding relevant provisions. Professionals remain responsible for reviewing quantities, pricing and disputed items.

01

Professional analysis

We check quantities and cost components against drawings, bills of quantities and pricing rules, taking site conditions into account when preparing our advice.

02

Independent judgement

For disputes over quantities, pricing or final accounts, we examine the basis of each party’s position and explain our findings. Revised drawings or additional records prompt a further review.

03

Continuous improvement

Recurring issues from account reconciliation, variations and final account reviews help us refine our review procedures and working methods.

04 / KNOWLEDGE INTO PRACTICE

Professional experience and AI

Professional rules and project records guide our use of AI for document organisation, comparison, retrieval and review.

Document organisation and filing.

Organise bills of quantities, drawings, contracts, instructions and variation records by project, identifying versions and sources so reviewers can consult the originals.

AI identifies matters for review. Professionals verify the findings and exercise judgement.

FIELD DATA / QUANTITY VERIFICATION

Site measurement & quantity verification

Drone-based site capture and 3D reconstruction provide terrain data and measurement records for quantity checks, progress assessments and final account reviews.

Record existing terrain and site levels

Terrain and elevation records are tied to the project’s survey reference system, supporting site appraisal and early earthwork estimates following land acquisition.

  3. 03Quantity review

Source imagery, model versions and measurement records are linked and retained for review.

Measurement and review

Measurements require checks of coordinate and elevation reference systems, control points and model accuracy. Volume calculations need a defined area and reference surface. Quantities are then reviewed against the contract’s measurement rules; obscured ground requires further verification.

DATA & PROFESSIONAL ANALYSIS

Project records and coordinated analysis

From source documents to project data, with origins, versions and review records retained for professional analysis.

CHENYI AGENT / IN PRACTICE

AI assistance in practice

Explore the work, application status and review requirements.

01

BOQ quality checks

Are the BOQ versions, quantities and summary figures consistent?

Internal use

Multiple versions, inconsistent headings and mixed summary and detail rows complicate BOQ review. The agent helps organise fields and units and flag duplicates, missing information and unclear sources.

Review outputs

Structured BOQ · Data-quality findings · Source references

Original files, worksheets and row references are retained. Incomplete files and unconfirmed versions need checking before formal analysis.

02

Cost indicator review

Are material quantities and unit costs unusual?

Internal use

Agents compare quantity indicators, rates and cost components for civil works, building services and preliminaries against comparable project records, helping identify omissions, calculation errors and unusual charges.

Review outputs

Discipline-level indicators · Review priorities · Evidence requests

Floor areas, units and scope must be checked first. An unusual indicator prompts review; drawings, quantities and contracts determine whether it points to an error or omission.

03

Contract terms & dispute review

How do contract terms affect pricing, adjustments and claims?

Internal trials

Our legal agent helps review pricing provisions, material price adjustments, variation procedures, claim deadlines and final account terms alongside project records, identifying the conditions that apply and points in dispute.

Review outputs

Referenced clauses · Issues in dispute · Evidence requests and draft review notes

Findings retain references to contract clauses and supporting facts and require professional review. Conclusions on legal disputes require further review by legal counsel.

04

Final account document review

Are the final account records complete and the submitted items supported?

Project trials

Contracts, instructions, site records, as-built drawings and final accounts are organised by item. The agent helps check versions, dates and work content, listing missing or inconsistent information.

Review outputs

Initial review findings · Document index · Missing-document list

Text recognition helps locate evidence. Professionals still verify originals, signatures and the facts; missing evidence remains an explicit request for follow-up.

05

Instruction, variation & site-record review

Was the variation carried out, and are any charges duplicated?

Project trials

Related instructions, design variations and site records are checked for approvals, completed work, quantities and pricing evidence, including duplicate claims and omitted credits for work already included in the original bill.

Review outputs

Linked review record · Cost-check worksheet · Evidence requests

Used in project trials to prepare findings for review. Cost adjustments and agreed final amounts require professional confirmation.

06

Pricing & material-rate review

Do the selected rate items and material prices comply with the contract?

Project trials

Contract terms, rate schedules, published material prices and supplier quotations support checks of unit rates and cost components, identifying items that need further quotations or pricing evidence.

Review outputs

Pricing review · Rate exceptions · Quotation priorities

Rates need comparable location, date, specification, brand, tax, transport and work content. Market observations and extracted figures do not replace an agreed project rate.

07

Standards, rate schedules & experience

Which rate-schedule item applies, and how should the work be priced?

Ongoing development

Search rate-schedule notes, measurement rules and published interpretations for the work in question, helping professionals check the selected items and applicable charges.

Review outputs

Relevant provisions · Pricing rules · Review points

Document organisation and clause retrieval are in use; automated rule checks are still being validated. Professionals confirm the applicable rate items, charges and treatment of each issue.
