lack of ownership for public areas environmental impact
The cities location along the cost promotes a windy, humid and moist climate. Strong winds, hurricanes and prosperous vegetation constantly facilitates further crumble of the city structures lack or resources
The repair and renovation that majority of Cuba can do in their household is limited to the building material that they can obtain
The cities location along the cost promotes a windy, humid and moist climate. Strong winds, hurricanes and prosperous vegetation constantly facilitates further crumble of the city structures corruption/ government
The political structure is not allowing for much flexibility, having rather large bureaucratic system uncertain future
rehabilitation process
The rehabilitation efforts in Havana Vehia separates the areas of the city. It removes restored or renovated buildings or areas from cognitive map of citizen of Havana.
Many Cuban families live one day at a time. The future prospects are uncertain, not many plan to much ahead. currency
The existence of two currencies perpetuates social segregation and equality
erosion processes
black markets
Without timely maintenance of damaged areas in the building the erosion processes start to decapitate materials.
More than 40% of consumer goods, supplies and tools are sold on black market
0.02 INTRODUCTION/ SCARCITY
Limitations Opening and running a business
Travel abroad The cars still in use are 50 years old American cars and 20 years old Russian cars. The supply of new cars and parts allowed for better preservation and upkeep of existing cars. Cuba have one of the largest number of vintage cars still in daily use. Cubans really proud of the cars that they own
Variety of goods for purchase
Variety of services provided
Freedom of speech
Access to world wide news After the collapse of soviet union in 1991 Russia stopped providing Cuba with medical supplies, food or oil. Since early 1990 Cuba is begging to produce naturally grown medicine. but to scarcity in western medicine Cuban doctors have advanced in applying and perfecting naturally grown and locally produced medicine.
Provided by state Education
Healthcare
Basic food rations Supplies and goods are scarce in Cuba, however what is available is enough to sustain the population. People are more economical, produce less west, consume less energy in good production.
0.03 INTRODUCTION/ HAVANA, CUBA
street and city dynamics
Few buildings in Havana fully renovated, most buildings in the city however inhabited. Industrial sites are given their own zones in the harbour area of the south of old Havana centre. Public transit is present but not well financed, therefore few buses are in operation to satisfy the demand. Most seek employment near the areas that they live in to avoid using public transport. Over the ears due to constant steam of tourists to the Havana vehia larger portion of the population has moved in to the old and central Havana to gain access to the tourist industry. For the locals the money that they make from interacting with tourists supersedes most of the available jobs elsewhere. City function with conjunction with touristy oriented areas separate from them. The local population have their own city fabric that overlay on top of “city for tourists” their own shops, attractions, schools, libraries, and repair shops. Children go to school (also to the after school activities); adults work, shop, cook, socialize. The “tourist city” is filled with Cuban’s for whom it is a workplace.
Transit hubs scattered around the city. The main and closest to the site of the “adaptation guild” is bus terminal in the near capitolium building. The bus terminal servers central havana. Other important transportation hub is the railroad station by the bay, it brings passengers from all over the cuba to havana, it also serves to bring goods and shipments to the city.
0.04 INTRODUCTION/ HISTORICAL GROWTH OF HAVANA
historic growth
Most of the urban sprawl happens gradually over past 500 years. The area of the old havana is where the first settlement was established. Rest of the growth was propelled with trading routs and smaller communities slowly merging with the city. In the beginning of 20th century most of the organic growth of the city was realized. Street and city planing was widely implemented.
morphing of the city
Social life in cuban society plays integrated role with their cultural identity and with what makes them cuban. Cubans share and pass information for the most part with “face to face” type of interactions. New information and news passed from person to person (sometimes it is a reason to start a conversation with a stranger). Observation on the social dynamics on the street indicates that conversations starts with ease and can last for long period of time. People like to stop what they are doing and chat.
Streets and city fabric is not all the same and have a specific type of differentiation based on where it is. I defined those types as to two basic types; public and private. Public street is one that used for business and work, most occupants of “public” street came here from somewhere else for a specific task, most don’t know anyone else and will not stay on the same spot for a long time. Users of the street here only in passing, there is no ownership to the commonly used spaces. Public streets are anything from tourist streets/areas, transportation hubs, city parks and recreation areas, shopping strips, industrial quarters, scarcely populated. “Private” streets include streets with just residential and some shops. (Small shops or open air markets). The difference between public and private is that most of the users of that street and any given time live on the street, live in the neighborhood or have friends or relatives living there. Idea for the possible future of the city as its morphs with its current state of problems, scarcities and adaptations to a mountain’s like with inhabited caverns of a city.
0.05 ADOPTATION OF THE CITY
tourists and locals
rooftop city
ruins on display
The number of tourists to the city of Havana is growing, however to most locals it is prohibited to interact with tourists, that create divide in Cubans interactions with foreigners.
It is becoming increasingly popular among inhabitants of the city to adopt their rooftops for urban garden. They would grow food and keep few chickens or goats there.
Due to scarce condition with materials and supplies a significant number of building withing old Havana are left to decay. Old Havana provides excellent place to observe various stages of urban decay.
0.06 ADAPTATION OF THE PEOPLE/ ADAPTATION OF THE BUILDINGS
ADAPTATION OF THE PEOPLE rural vs. urban
Rural vs. urban lifestyle. After embargo became in effect in mid 1950 significant number of individuals from rural areas moved to bigger cities. Rural lifestyle is slowly interweaving itself into city’s fabric.
growth in city’s population
With influx of inhabitants in major cities and general family expansion, there is less and less space available for everybody.
scarce resources
With embargo in place and overall state of economy there is a significant limitations in place. Food and basic supplies are provided but only enough to survive.
ADAPTATION OF THE BUILDINGS hiding
Most of the building in old Havana are in similar condition of decay and ruination. The front facades reveal little about what is happening inside the block, some hide slams and some hide rich families.
adding/ subtracting
Due to decreasing availability of livable space many Cubans seek any possible ways to add to existing living quarters. Often it is done by adding mezzanine levels or constructing inhabitable sheds.
change in function
Over time some of the public buildings significantly changed their usage and function. Particularly churches and convents. after the revolution many became appropriated for storage or other governmental usage.
0.07 SITE/ CONTEXT ANALYSIS & STRATEGY
public street
On “public street” there is a lot of pedestrian traffic, shops, restaurants, bust stops. Street is wider and nosier. Most users do not necessary live on this street or ever in the nearest area. semiprivate
Semiprivate street is usually serving immediate streets and inhabitants that live withing walking distance. In vacant lot or at a corner people can buy fresh produce.
private street
Private streets are usually narrow and quiet, mostly no vehicular traffic and little or no shops. Small vendors sell some produce from the cart. Most people eater living on this street or visiting friend or relative. A lot of interactions on the street and insider houses. Passes by can gaze inside living rooms of the apartments situated on first level. With no glazed windows and open doors the boundary between street and living room is blurred.
network digram for professional services
The adaptation guild sprung itself from the remaining porting of the “hotel de isle de Cuba”. The form of the building occupy the most the site. The new addition lifts up form the ground to provide for a well shaded plaza that would serve both communal gathering area and a trading area for the guild The main workshop is located directly above the plaza and have easy access both from the ground floor and from adjacent classrooms and guild spaces. The shape of the adaptation guild represents the adapting and of the skin to the spaces it envelopes where the size of the members and frames starts to address the needs for shading and ventilation of the spaces it envelopes. 1. The old portion of existing building is removed 2. The remaining porting is represents the guild and occupied by the adaptation guild programme 3. The new adaptation to the guild of making and creating lifts above the connectivity plaza.
0.08 ESTABLISHMENT OF ADAPTATION GUILD
workshops and workman in havana
Central and historic part of Havana was established over 500 years ago with majority of the buildings in old Havana dating 80-70 years back. The economic instability of the past 50 years and lack of resources have a condition where smaller repair guilds and workshops are establishing themselves around the city. The workshops can range from a specifically used for purposes of workshop large space on the ground floor of a building to smaller room in a house occupied and used during the day by a specific craftsman. City lucks centralized establishment for a repair and renovation efforts. The problem is that storage of the materials, supply, workshops space, craftsman are all dispersed trough out the city. Adaptation guild is striving to centralize and bring together variety of construction and building renovation professional working under the same roof to provide services, education and resources. Adaptation guild also will provide larger workshop that would be accessible to the public.

health and safety
Before the demolition of the existing portion of the building slabs and walls will be tested for presence of asbestos, levels of radiation. Demolition process will be handled in accordance with contractor management regulations. The cdm coordinator will be monitoring and notifying the contractors of potential hazardous materials and substances. The role of cdm coordinator would be to ensure that at the design stages the potential risks and health and safety issues would be identified and properly addressed. The first aid point will be located at construction site hut. During construction sequence and process the safety inspector will be responsible for: -inspecting safety conditions on site -compliance of the contractors with the safety requirements -provide regular safety instructions and lectures -issue warnings if safety requirements are not followed. The safety measures will also will be undertaken to ensure that everyone outside of the construction zone and who is not part of the construction is safe from potential hazardous materials and falling objects. Those measures will include: -provide adequate fence around the perimeter of the construction site -on erected scaffolding provide safety net around the perimeter -provide warning and advisory signs to advise public to use alternative route while part of the road or sidewalk will be blocked with construction process. When possible painting and welding will be done of site. Any painting that will be done on the construction site will be done with accordance with regulations to have appropriate ventilation, and protective gear worn by the worker who is performing painting job. The pouring of concrete will be done with safety regulations handling hazardous materials The overhead installation of insulation and aluminium panels will be a particular challenge during the construction process. The design and configuration panels allow for simple assembly with standardized connections.
1.05 CONSTRUCTION METHODS
DEMOLITION AND EXCAVATION Slope of the excavation pit depends on the condition of the earth
construction method
1. Preparatory steps. Future demolition portion will be tested for toxic materials, power and water lines will be temporary shut or rerouted. During this stage following will be performed: -testing for asbestos -cutting power -cutting water
FOUNDATION
Foundation footing and walls installed on the basement level
2. Demolition Demolished debris will be taken off site to dumping grounds, portion of debris will be retained to be used for foundation walls construction. The portion of the historic facade will be preserved during this phase and held back with supporting scaffolding 3. Excavation The area where basement is located will be excavated. The excavation pit will have sloped sides depending on soil. Soil will be tested in key location to determine what foundation will be more appropriate depending on the composite of the earth. Prognoses for type of foundation used will be spread footing. 4.Foundation and plaza The excavated area is levelled, foundation outline is dig-gout and reinforcement is placed. Areas that will have slab poured will have a thin layer of sand applied and a layer of water proofing. During this stage following will be installed: -foundation walls -structural columns -water line and electrical tie ins -fire escape and elevator cores are erected
STEEL FRAMEWORK
Steel H columns are installed on top of foundation walls and columns
4. Structural columns and beams After the plaza level is poured with concrete main steel columns will be installed, following the structural beams and steel frameworks that will hold aluminium skin. Structural frames will be first assembled where columns are to provide for initial support. 5. Floor slabs Prior to floor slabs metal decking will be installed on steel “H� beams as long with appropriate reinforcement. Each poured slab is to cure for 21 day before allowing for any heavy load placed on it. 6. Skin frames and aluminium panels Rest of the steel frames to support the skin will be erected. While this stage is commencing aluminium skin panels are installed to create envelope for the building. 7. Glazing and External finishes Glazing and rest of aluminium panels are installed to complete weatherproofing the building and allowing work on the interior envelope to commence.

Concrete platforms installed during plaza construction process provide pin connection to steel frames that hold the skin
BASEMENT
Completely underground and have foundation walls, concrete structural columns that support steel H columns above plaza level
1.06 STRUCTURAL STRATEGY/ SKIN
structural strategy
Structure will be comprised of truss system that will support the envelope of the building and allow to support part of the overhanging floor plates at the workshop area. The main structural support will be on the beams and load-bearing walls. Columns will be a pile in structural system, after columns are erected trusses and beams will be supporting floor pates. Cantilevering portions will be supported by structural trusses that wraps around the building and serve as main support for aluminium panels (that compose the envelope of the building). steel frames configuration
The configuration and design of each supporting steel frame is depending on the function of the spaces that will be enveloped by particular steel frame. Numbering in total 30 frames they are comprised of and welded from straight trusses to create unique shape. Key truss will be installed first (right after the structural columns and beams are erected). That will allow safe and continues installation of frames to be commenced after floors poured and provide for further skin installation.

Smoke detectors and emergency light and signs will be installed as per regulation for small assembly and workshop area.
2. Classrooms, offices and assembly areas Victaulic Vortex Fire Suppression Systems. Water and nitrogen are used by the Victaulic Vortex fire suppression to halt fires from spreading. An advantage with using the Victaulic Vortex fire suppression system is its capacity to lessen the amount of oxygen fuelling a fire. This type of system can be used to contain a fire while there are occupants in the area and is eco-friendly.

means of egress/ fire safety
Fire safety includes fire rated egress stairs that is located at two opposing locations in the building. The escape paths will be indicated with lighted “exit” sign. The maximum path of travel to the egress staircase is not superseding 70’ for any of the egress staircases. The workshops and classrooms will have stationary fire extinguishers mounted on the wall. The fire extinguishers will be regularly checked by the fire inspector. The fire inspector is also to check on all the sire suppression and fire safety procedure (such as clear path of egress, functioning fire alarm system, emergency lights). The fire evacuation tests and simulation.

Ground FLOOR ACOUSTIC ZONES
There is two distinct types of spaces. Workshops and assembly areas generate noise and do not require any protection from sound coming in classrooms and offices need to be soundproofed from the incoming sound from workshops. The location of workshop is not severely distracting to the adjacent building and streets because it is not directly sharing any wall with another building or space. The workshop is producing on average from 60 to 80 dba and would require a soundproofing to reduce it down to 40 dba, reduction to 40 dba would be adequate for the adjacent on one side classroom spaces. Classrooms need to be acoustically protected to maintain 40 dba inside the space, to achieve that acoustic wall assembly will be used on the walls, acoustic ceiling will be installed on the ceiling and carpeted floor tiles for added noise reduction.

3.02 OVERALL ENERGY STRATEGY/ CONSERVATION METHODS
overall energy strategy
Strategies: -self shading the configuration and orientation of the skin ribbons allows for most of the spaces to be self shaded. The taller ribbons located at the south side of the site, all subsequent ribbons are slightly shorted. -Ventilation trough out the building The outside air will be puled in at the lower portion of the building and circulated trough the building to allow adequate air movement to discharge of hot air concentrating at the topmost areas of the workshops. The skin of the building will have four areas where operational grills will be installed to allow for passive cooling and ventilation. -Solar panels will be later installed on top of the old portion to the building for to minimize power consumption from city’s power grid -Equipment in workshop is functioning at 240 volts therefore step up transformer will be required to provide required voltage. Transformer will be located at ground floor in the back of the storage room in its own separate room. The workshop will be functioning during day time hours with closing the public workshops for the night. The guild workshop will be open later and will be open for weekends. -Portion of the rainwater will be collected and stored for future use in the workshop and to flush the toilets. the collected rainwater will be filtered prior to be feed into the system. Overflow of the collected rainwater will be discharged to the city’s sewerage
3.03 SOLAR GAIN/ NATURAL LIGHT AND SHADING
natural light and shading
The functioning of the guild will be during daytime, while there will be adequate lightning layout to provide for required lightning levels at workshops and classrooms. The building is self shaded with enough of variance in the ribbons that envelope the spaces that it also allows for north light to illuminate workshop areas guild offices and classrooms will require more light introduced to the space.

MAIN WORKSHOP NATURAL LIGHTING natural light
Floor hight and distances between skin ribbons allows main workshop to have no direct glaring sunlight. The main source of light is a reflected sunlight that provides soft ambient lighting. The individual task desks and pieces of equipment will have spot light to provide required necessary lumen’s for them. The natural lighting will be source of ambient lighting however florescent lightning grid will provide majority of required lighting.
lighting zones
- workshop 750 lumen/m2 - classroom 500 lumen/m2 - office 250 lumen/m2 -assembly area 100 lumen/m2 solar gain
DETAIL 3.03B CRAFTS WORKSHOP NATURAL LIGHTING
The highest amount of solar gain would be at the south side of the building at the assembly area, the environmental strategy to use self-shading technique to keep building envelope and spaces inside from accumulation direct heat gain throughout windows and openings. While uneven skin cover of the building allows for north light to be introduced to the spaces bellow. Resolution for heat gain -Assembly area will have higher ceiling with a ventilation shafts leading to the south side of the building -Workshop will also have high ceiling that will allow for collection and discharge of hot air -Classrooms and guild spaces do not have as much glazing or exposure of the envelope of the building to the sun to accumulate high heat gain -Guild workshop will have higher ceilings and large open floor plan for air circulation
3.04 VENTILATION/ HEATING AND COOLING
TOPMOST VENTILATION
TOPMOST VENTILATION
Ventilation grills are located at each skin ribbon at the crest of the ribbon at each side of the building
The trough draft at topmost areas allows to pull out hot air raising to the top of the building
SUMMER TIME VENTILATION SCHEME
During summer time months all of the ventilation grills are open and allow easy intake and discharge of the air as it passes trough the building. The ventilation openings at Ground level will allow for fresh cool air intake while the ventilation openings at the top of the building will allow for circulation and discharge of hot air raising to the ceiling
BACK OF THE BUILDING
The ventilation grills are located within 1m from the ground allowing for best draft and overall circulation of the air to be achieved
WINTER TIME VENTILATION SCHEME
During cooler winter months the topmost and opposite of it near the ground level ventilation shafts will be closed. Remaining ventilation shafts will also adjusted to allow adequate air flow. By closing the topmost ventilations will allow for warm air to remain in the building and provide comfortable atmosphere in the workshop area, while remaining ventilation shafts will allow for fresh air circulation.

Grey water -The sanitation and overflow in collected rainwater will be disposed off by connecting to the city’s sanitation line. -Additional water supply will be provided by the collected rainwater that will be stored in the storage tank underneath the plaza. The access to the tank and the pump will be trough the hatch in the storage area and will lead to a smaller room where the tank will be sitting in the middle and would be accessible for service. The filtration and pump will be located there as well. Collected rainwater will be used to flush toilets and for cleaning and using water for workshop area.
3.06 ENVIRONMENTAL IMPACT OF MATERIALS
environmental impact of chosen materials
Low cost in building maintenance is main focus in choosing and specifying materials. Therefore material selection will take into the account its life span and maintenances efforts as well as manufacturing process. Manufacturing and assembly -The manufacturing of steel is not one of the most environmentally friendly processes however the lifespan and impact on environment once in use is minimal. The manufacturing of steel is high on energy consumption and delivery has grater impact since part of the steel members will be shipped overseas however the ease of assembly and speed with which the building will be erected will allow to compensate for some of the initial environmental impact. -The assembly of steel frames with aluminium panels and frames will be quickly assembled on site which will minimise environmental impact due to the construction method. Maintenance -The building envelope will not be painted therefore eliminating need for toxics released while painting. -The materials used on the exterior will be replaced as required per manufacturing warranty or if damaged. Lifespan -The steel, aluminium and glass are expected to last for 60-100 years without major renovation or refurbishment done. -Interior finishes are expected to last 15-20 years -Interior finishes and materials also will be selected on the bases of their procurement and composition. Paint will be selected as low toxicity index, carpet and vinyl tiles will be used Construction waist and excess will be collected and disposed accordingly.
3.07 BUILDING LIFE CYCLE/ IMPACT

building life cycle
Renovated portion The existing portion of the building will be renovated with the new finishes, servicing systems and equipment. The expected life cycle for the building will include minor repairs and replacements. old building life cycle is approximately 35 years before major renovation jobs will be required -The renovated portion of the old hotel building will be stripped of all the interior finishes. There will be minimum amount of interior painting to reduce environmental impact from repainting works -All of the electrical wiring will be replaced (need to be serviced and replaced every 10 years) -All water and sewerage pipes will be replaced to prevent potential leaks. (estimated life-cycle 50 years) New addition -The adaptation guild addition life cycle is 50 years
BACK FACADE New additon
Life cycle assessment (lca) is a method for evaluating the environmental load of processes and products during their life cycle from cradle to grave it attempts to identify the environmental effects during all stages of the life of a product and produces a figure (or several figures) that represent the environmental load of a product. It is a process that is becoming more widely adopted in the context of national and international environmental regulations. The life cycle analysis will be performed by UK based consultants
SECTION 4.00 PROCURING THE BUILDING

site location old havana
central havana
planing constants
The city of Havana is undertaking a renovation efforts that in its infinite steps and now starting from several key and historic plazas. This points in the city will become catalysts for future spread or renovation for the whole of the historic part and central Havana. Right now in the city the main investment efforts coming from overseas investors who purchase properties in historic part of the city and revitalize and renovate some of endangered and historic buildings. The Cuban government focuses its renovation efforts. To begin renovation in Havana -The construction documentation needs to be submitted to the “oficina del historiador ciudad de la habana” (official for historic preservation, city of Havana). -The project than will be evaluated by “official for historic preservation” on its impact on the historic part of the city. -For building title (permit) building proposal, architectural drawings, site drawings (including earthwork and demolition plans) will have to be submitted to the building authority similar to LPA (local planning authority) in UK -Planning permissions are usually granted subject to a planning condition which requires the development to be commenced within three years. Typically they will also include a number of other conditions ( for example undertakings regarding environmental and noise issues; limits on the size and external appearance of a new development; the scheme to be built in accordance with the approved drawings, trees to be planted as per the landscape scheme and replaced if they die in the first few years, or the colour and finish of external materials to be approved by the local authority). -Some of the planning conditions will need to be complied with before any work starts on site; others will take effect once the development is commenced, or later.
local context
The site located within the area that is considered historic centre of old Havana, the rules and regulations apply to that as such for renovations and new construction. Old Havana is a world heritage site and listed in UNESCO. the compromise for demolishing part of the existing historic building is to keep 70% of the original facade. The later addition to the hotel is not considered historic and do not have as much constrains with its demolition. -The new construction needs to comply and health and safety codes -Renovated construction needs to be retrofitted to comply with the most current safety and accessibility regulations

europe united states
procurement route/financial context
russia china
australia
procurement route
The skin of the building is formed of prefabricated modular elements (steel structural frames and aluminium panels covering those frames). The fabrication process will involve steel that will be produced and supplied overseas because Cuba’s steel production doesn’t have capacity to produce quality steel in required project time frame. Similar is with other products and material which will be supplied from overseas. Locally supplied would be all the wood required for the construction as well and sand and stone. To decrease cost of construction form-work will be recycled and parts of demolished building will be used in construction for foundation walls (cyclopean concrete). The suppliers for steer will be selected in a bid process which will allow for fair selection of suppler with lower cost, preference will be given to the local suppliers who can competitively present products that meet required specifications.

off site location for delivery, storage and partial assembly
adaptation guild site
To store majority of the materials coming from overseas and locally a of site facility will be set up to provide storage and assembly area. The offside location will be function beyond the construction time-frame. The offside location will be placed in one of currently underused and partially abandoned warehoused in the bay area providing easy access to it by ships and close proximity to the building site. After the construction is completed offside location will store all the raw materials of larger scale needed for other renovation projects around the city. financial context
The funding to the project will come from adaptation guild funding (part of it is donations from local community), donations from industries and individuals. Besides financial contributions, other types of contributions is pledged by various organization and “office of historic preservation” - 20 ton of steel from “Hebei Steel Group” as part of their program to support development in struggling or under-developing countries - adaptation guild have agreement to employ 20 professionals from local community of craftsman giving them place in the guild once construction is completed. Budged and costs will be incorporating -Design development and engineering costs -Site survey, preparation and tests (hazardous substances, soil test) -Insurance and legal costs -Site preparation, demolition and disposal -Temporary constructions (scaffolding, framework) -Construction cost and building cost -Overheads (architect, contractor)

The architect and contractor work together in a joint venture, both coordinating the subcontractors to get the project built. The building owner has a single contract with this joint venture. The architect leads the joint venture so in supervising the subs, the contractor might defer to the architect. the architect might bear more risk than they do in the traditional approach but risk is shared with the owner and the contractor, as outlined in their agreement. An alternative approach to effectuating this delivery structure is for the architect to contract directly with the owner to design and build the project, and then to subcontract the procurement and construction responsibilities to its allied general contractor, who enters into further subcontracts with the trades

CLERK OF WORKS
SUBCONTRACTOR
CONSULTANT
-Dynamic: design–build is a construction project delivery system in which the designer and constructor are teamed together (or are a single entity) rather than each being hired separately by the owner or developer. If teamed together, the designer and constructor may be in a joint business venture, or one may be the subcontractor of the other. -Efficient: typically led by contractors, ‘design–build’ has evolved as an efficient way to deliver projects primarily where the building project goals are straightforward, either constrained by budget, or the outcome is prescribed by functional requirements construction industry commentators have described design–build as a high performance ‘construction project delivery system’, a dynamic approach to making buildings that presents an alternative to the traditional design-bid-build approach. -Single-source: design–build is growing because of the advantages of single-source management: unlike traditional design-bid-build, it allows for the owner to contract with just one party who acts as a single point of contact, is responsible for delivering the project and coordinates the rest of the team. depending on the phasing of the project, there may be multiple sequential contracts between the owner and the design–builder. The owner benefits because if something turns out to be wrong with the project, there is a single entity that is responsible for fixing the problem, rather than a separate designer and constructor each blaming the other.

In design–build projects led by architects, the architect has the opportunity to lead the team through progressive iterations during the design–build process instead of producing sequential, schematic, design, construction drawings and construction administration documents. These continuous feedback loops extend the phase in which the team is dedicated to producing the most informed design. each iteration is progressively informed by budgets, continuously improving information and the best efficient construction techniques. The dynamic architect-led design–build work-flow reintroduces discursive coordination, collaboration and consistent, reflexive managerial oversight over the arc of a project schedule, maximizing project efficiency (time, cost, functionality) without compromising design performance or the quality of project outcomes. design–build can be an iterative and dynamic method, reflecting an emergent design process in which decisions are made holistically and progressively refined as interdependencies are prioritized, identified and coordinated. The architect will be proving and coordinating information both for Cuba based suppliers/ consultants and uk based suppliers and contractors.

Environmental risks -Storm water pollution: as a result of construction, the soil is displaced from its original location which can possibly cause environmental problems in the future. Runoff can occur during storms which can possibly transfer harmful pollutants through the soil to rivers, lakes, wetlands, and coastal waters -Vegetation: there may often be particular trees or other vegetation that must be protected on the job site. This may require fences or security tape to warn builders that they must not be harmed -Wetlands: the contractor must make accommodations so that erosion and water flow are not affected by construction. Any liquid spills must be maintained due to contaminants that may enter the wetland -Historical or cultural artefact: artefacts may include arrowheads, pottery shards, and bones. all work comes to a halt if any artefact are found and will not resume until they can be properly examined and removed from the area -When construction vehicles are driving around a site or moving earth, a lot of dust is created, especially during the dryer months. This may cause disruption for surrounding businesses or homes. to prevent this a water truck will be driving trough the site spraying water to minimize the movement of dust out and within construction site
