Site & Environmental Analysis:
Overview (8)
- = land planning, urban design, & enviro evaluation (Typ involves specialty consultants)
- process of studying the contextual factors that influence how to situate a bldg, layout/ orient its spaces, shape its enclosure, & establish relationship to the landscape
- not a basic arch service = an additional service
Analysis should include;
- physical, cultural and regulatory factors
- urban design issues and planning processes
- environmental issues (min. disturbance, reduce erosion, protect habitats/ biodiversity, protect water/ limit pollution, reduce heat island effect & light pollution)
- Grading and stormwater management
- Energy performance of a building & placement on the site
- Universal accessibility
- Environmental (ESA) and engineering reports (geotech/ sbsrf)
- Land survey (location/ descr of any features that would effect constr) and topographical map (srf)
- based on the relationship btwn the exist. natural & built features on a site and the proposed construction
- The micro climate, topography & natural habitat of a site influence design decisions very early on
- Adapt bldg to the landscape, path of the sun, wind & flow of water on a site
Site & Environmental Analysis:
physical, cultural and regulatory factors
= land planning, urban design, & enviro evaluation (typ involves specialty consultants)
- Physical Factors (enviro & climactic):
- Cultural Factors: site history, land use, community services/ amenities, archeological
- Regulatory Factors: zoning & land-use, regulations/ legal restrictions
Coordinating Engineering Systems:
Overview
- Architect responsible for the selection, design & coordination of all bldg systems based on; System benefits & limitations, Availability & cost, Space requirements
- Architects must understand how eng systems work for successful coordination with eng consultants & product suppliers
- structural system: support & transmit loads (gravity and lateral) to ground
- The mechanical system: create healthy, comfortable & safe space by provide essential services to the bldg (water supply system: consumption & sanitation, Drainage/ Sewage Disposal system: fluid waste & organic matter, heating, ventilation, air conditioning systems: occupant comfort, Fire Fighting system: detect & extinguish, Waste disposal system)
Coordinating Engineering Systems:
Structural
- struct elements must be sized, configured & joined to form a stable struct under any possible load condition = vertical (gravity) & lateral (wind & earthquake) loads
- therefore oversized to account for any load configuration
- struct. system defines a grid based on where col & bearing walls collect loads from beams/ horz. Elements (can inform bldg design & organisation of program activities)
- There is a fundamental relation btwn the span of horz. elements & the spacing of vertical supports (the struct system) that influences the dim. & scale of spaces ex: Proportion, Dimensions, Scale
Analyse struct system in terms of:
- Allowable ranges/ spans
- Costs (labour & materials)
- incombustibility/ combustibility
- Assembly time
- system flexibility
- Loading
Coordinating Engineering Systems:
Mechanical
Heat Transfer:
- conduction (direct contact)
- convection (circulatory motion, gravity - hot air rises)
- radiation (electromagnetic waves/ thermal energy, no motion req)
- evaporation (humidity/ water vapour)
Facots affecting comfort:
- mean radiant temp: temp of surrounding srf, always lower or higher than air temp, (most important, higher # = lower air temp)
- relative humidity: ratio btwn water vapour in the air & amount the air can hold (higher # = lower air temp)
- air motion: heat loss by convection & evap., air speed = important
- the size of HVAC equip. is det. by heating & cooling loads:
- Heating Load: hrly rate of heat loss in a room, HDD = 1 degree-day below the standard temp
- Cooling load: hrly rate of heat gain in a room, , CDD = 1 degree-day above the standard temp
- Degree day = 1 degree diff in mean daily outdoor temp from a standard temp. = used to calc H/C loads, size HVAC equip, calc fuel consumption
- HVAC Systems: Det the temp, humidity, quality, distribution & circulation of air in a bldg:
Coordinating Engineering Systems:
Impacts on Project (5)
The selection, assembly & integration of bldg systems are determined by the following factors:
- Performance req
- Aesthetic Qualities
- Regulatory Constraints
- Enviro Impact
- Construction Practices
Coordinating Engineering Systems:
Coordination
- Manage communication among/ between all consultants
- Provide direction on design decisions to all consultants
- Review services of all consultants to identify concerns & compliance
- coord of arch design w/ design of engs and other consultants
- coord of management of the project
Cost Management:
Factors influencing cost
- Economic & political: inflation, market conditions, interest
- Site Context & climate (enviro factors): location, weather
- Bldg type & design:
- Process & Owner/ Client/ Stakeholder Req
- Changes in project req/ scope/ FP
- Type of construction project delivery
- Owner responsibilities & timetable
- Regulations
- Atypical work arrangements
Cost Management:
cost estimating methods
- Analogous: analogy drawn from a previous project
- Parametric: most common, applies measurement of a bldg, system or component against a known cost per unit
- Bottom-up: includes estimates for hours, labour rates, materials, logistics, overhead, = most accurate but most effort
- Classification: Class, D,C,B,A
- Life Cycle Costs: = capital/ initial cost AND operating & maintenance costs
