Evidence at a glance
- Evidence level
- Mixed: official guidance, established building science, project method and site-specific findings.
- Application type
- DALLEAU project method; site-specific validation required.
- Published or updated
- Updated 29 July 2026
- What this did not prove
- A baseline does not establish universal flood, noise, heat, utility or resilience performance.
Tropical Site and Resilience Baseline
Embedded in Feasibility Study and the Full Development Mandate when relevant.
Why the baseline exists
A site can look right and still be wrong for the intended residence.
The same piece of land can produce very different outcomes depending on how the household will use it, whether the residence opens or closes, how long it remains vacant, where noise arrives from, how water moves during heavy rain and whether the systems can be maintained locally.
P01 brings those conditions into the owner’s decision before they are disguised by a concept render.
Site conditions as project inputs
The land is assessed as an operating environment, not only as a view or address.
Climate and exposure
Sun, shade, wind, external humidity, rain exposure, elevation, heat gain and the practical difference between open, mixed and closed modes.
Water and drainage
Site levels, stormwater paths, driving rain, water source, drainage assumptions, wet-season observations and conditions that need civil, geotechnical or laboratory review.
Noise and privacy
Day and night events, roads, neighbouring uses, equipment, ceremonies, construction risk, quiet-side potential and the implications for bedroom and private-zone placement.
Access and serviceability
Owner arrival, staff and supplier access, waste and service movement, maintenance routes, emergency access and the practicality of reaching technical areas later.
Utilities and resilience
Power, communications, water, backup assumptions, network reliability, equipment support and the consequences of interruption or delayed service.
Landscape, insects and corrosion
Planting, roots, water retention, mosquito conditions, coastal or saline exposure, material vulnerability and the maintenance burden created by the landscape concept.
Owner-side sequence
Observe. Classify. Trigger. Record.
Step 01
Observe at the relevant time
The baseline uses available surveys, structured site visits, photographs, event logs and observations at times that matter. A daytime visit alone cannot establish night noise, wet-season behaviour or vacancy performance.
Step 02
Classify the evidence
Each conclusion is marked as official guidance, evidence-based recommendation, DALLEAU project target or a question requiring local validation.
Step 03
Trigger the right specialist
Where the question requires surveying, engineering, geotechnical work, acoustic measurement, water testing, legal review or another regulated conclusion, DALLEAU records and coordinates the appointment rather than claiming the answer.
Step 04
Record the owner decision
The recommendation, unresolved risks, design invariants, responsible parties and accepted conditions enter the Owner’s Control Report before the project advances.
Before concept lock
The baseline can change more than the building position.
- Buy, reject or proceed with conditions
- Bedroom and quiet-side placement
- Open, mixed and closed operating modes
- Level and drainage strategy
- Service edge and maintenance access
- Landscape setbacks and water management
- Utility resilience and backup priorities
- Specialist appointments
- Contingency and unresolved-risk allowances
Release conditions
The project does not move past the site questions by assumption.
HP1
Before a land recommendation
The minimum site evidence is assembled and unresolved red flags are logged. The result is go, conditional go or no-go, not a promise that all future risk has been removed.
HP2
Before concept freeze
The operating-mode map and room risk map are approved. Material conflicts between openness, noise, humidity, rain, privacy and serviceability remain visible.
HP3
Before developed design
The specialist trigger schedule is accepted. Material unknowns have an owner, method and later verification date.
Evidence and outputs
A baseline that can control later decisions.
Outputs
- Site observation pack
- Photo and event log
- Risk heat map
- Operating-mode map
- Source and uncertainty register
- Owner decision memo
- Specialist trigger schedule
- Baseline entries in the Building Passport
The output is not a certificate. It is a documented basis for the next owner decision and the next specialist appointment.
Who does what
DALLEAU frames the risk. Appointed specialists determine regulated conclusions.
DALLEAU
Defines the owner-side questions, organises the evidence register, conducts structured observations, compares options, maps operating modes and records the decision path.
Appointed specialists
Licensed surveys, engineering calculations, code compliance, geotechnical conclusions, formal acoustic measurement, water testing, environmental assessment and legal or title opinions remain with the relevant appointed party.
Limits
A baseline cannot prove the future.
Future neighbouring development, exact wet-season behaviour, long-term water quality, rare noise events, hidden soil or drainage conditions and actual operating response remain partly unverified until later specialist work, rain events, construction, commissioning or occupation.
Local translation
Bali is not one climate or one operating condition.
Micro-location, elevation, wet-season water routes, driving rain, external humidity, night-time activity, insect pressure, coastal corrosion, power and network stability and local service capability can materially change the project response.
The protocol therefore preserves site-specific questions instead of importing a single tropical formula.
Carried forward
The site decision remains visible after acquisition.
Owner’s Control Report
Land recommendation, principal risks, operating modes, design invariants, specialist triggers, residual risks and owner decisions.
Building Passport
Restricted site records, survey versions, risk map, utility assumptions, water and drainage information, baseline photographs and future verification dates.
POE
Wet-season drainage, external noise events, open versus closed mode use, utility interruptions, landscape maintenance and vacancy performance.
Before the concept is fixed
Bring the site conditions into the owner decision early.
P01 is activated inside the Feasibility Study or Full Development Mandate when the land, concept or existing residence requires a structured tropical baseline.
