Before we begin
Getting started
with the right support for your project
Questions to consider when planning your home in Thailand.
Can I speak to you before choosing a contractor?
Yes. You can contact us while planning your home in Thailand, even before choosing a contractor. Share the drawings, bill of quantities (BOQ) or proposed contract you have. Our engineers can help you understand the technical points to discuss with prospective contractors.
How do monthly visits differ from a full-time site engineer?
Monthly supervision means 4, 8 or 12 visits at intervals agreed with you. If you need an engineer on site every day, our team can help plan a service suited to the project.
Do you also provide construction management (CM)?
Yes. WISAWA can help with schedules, project documents and coordination between the people involved in construction.
The team can review schedules and work quantities, attend project meetings, review completed work against payment claims, and review variation documents. We plan this support with the project owner.
Which areas do you cover, and how are travel costs handled?
We serve Bangkok, surrounding provinces and projects within a 200 km drive of our Khlong Sam Wa office. Travel costs depend on the site location and are confirmed before the service begins.

CONSTRUCTION MANAGEMENT
Construction consulting and management (CM)
Support with schedules, documents and coordination. Explore the ways our engineering team can help your project.
Representing the project owner
Support with construction details, from planning to quality inspections.
Read the details
Tips : Homes, commercial buildings, factories and larger projects all involve many details and stages, including planning, design coordination, contractor selection, budget review and quality inspections. A construction management team can act as the owner’s representative to help coordinate these activities. Read the article (Thai) →
Reviewing schedules and contractor quantities
Review the BOQ, materials, labour and work quantities against the construction plan.
Read the details
Tips : A construction consultant’s role includes reviewing the BOQ, (Bill of Quantities) , the suitability of materials and labour, pricing, consistency with the original plan and potential risks. Read the article (Thai) →
Coordinating with the relevant parties
Help coordinate construction matters with other organisations and project participants.
Read the details
Tips : Construction coordination can help reduce the owner’s administrative workload. The consultant can handle agreed construction communications and coordination, leaving the owner time for other responsibilities. Read the article (Thai) →
Monitoring progress with an S-curve
Compare planned and actual progress to identify delays and follow up on their causes.
Read the details
Tips : An S-curve compares the construction plan with actual progress. If actual progress falls behind the plan, the supervising engineer reviews the possible causes, such as materials procurement or delays between the main contractor and subcontractors, as well as weather and other project constraints. Read the article (Thai) →
Coordinating drawings before construction
Check for inconsistencies between structural, architectural and building services drawings.
Read the details
Tips : Drawing conflicts occur when different sets of drawings, such as structural drawings (Structural Drawing), architectural drawings and building services drawings (MEP Drawing) do not align with one another. For example, columns, beams or pipe positions may conflict with the architectural layout, or plumbing and electrical conduits may clash with structural elements. Read the article (Thai) →
Reviewing additions and omissions
Review changes to the documents and work quantities to summarise project variations.
Read the details
Tips : Changes during construction are often recorded as variations. The consultant can review the details of added or omitted work, calculate changed quantities and assess the associated costs, , then help discuss and document the outcome. Read the article (Thai) →
Project meetings and issue follow-up
Help the owner and project team share an understanding of progress and outstanding issues.
Read the details
Tips : Weekly or monthly project meetings bring together the owner, contractors, designers and other participants to review progress, exchange information and address issues. The consultant helps plan, organise and facilitate these meetings. Read the article (Thai) →
Reviewing completed work against payment claims
Compare the work on site with the BOQ and drawings before reviewing the amount claimed.
Read the details
The supervising engineer checks actual site progress against the contractor’s reported work, using measurements and counts of completed elements where appropriate. The consultant then compares the quantities completed with the payment claim, referring to the BOQ and construction drawings. Read the article (Thai) →
Recording agreements during construction
Keep a record of changes and additional agreements that the team can refer to later.
Read the details
Tips : Recording changes and additional agreements helps clarify added work, altered scope, materials and working methods. These records support clear communication and later checks of what was agreed. Read the article (Thai) →
