- 1. The Challenge: Practical Considerations & Possible Solutions: A. Clear understanding of how facilities are to be used and managed 1. Consider ways of mapping/tracking social processes: not merely a hand-over point but a process as sharedgestation and construction 2. Safety planning must begin at same time as the planning of spatial and design requirements for facilities B. Skills transfer 1. Illustrated through development/ production of mosaics, calcrete facings, planters, tree cages, security screens, landscaping C. Sufficient flexibility for users to adapt space for specific requirements. 1. Retro fixing of shelves etc. by tenants 2. Nails / drilling resulted in punctured water pipes & severed electrical conduits/cables 3. Utilise finishes/decoration to clearly identify where services are situated and where fixing to walls can take place D. Demarcation of public space boundaries 1. Ensure no ambiguity in terms of public/private spaces 2. Need to avoid conflicts between public & private spaces E. Community driven management eg: High mast lighting 1. Management of these to be community driven. 2. Renewable resource e.g. LED lightings needs to be explored User Requirements of Places, 1.1 OWNERSHIP This section concerns the necessary mechanisms for "place management" - promoting community ownership, responsibility, and pride. Furthermore, it takes into consideration how to design for community & public safety with priority on surveillance & visibility as well as special needs groups. Spaces, Buildings, & Facilities
2. The Challenge: Practical Considerations & Possible Solutions: A. Incorporating neighbourhood watch/leadership structures into design of all facilities. 1. Impact on previously un-occupied/ un-owned land i.e. questioning of existing boundaries 2. Appreciation of new challenges & conflicts which new facilities may inadvertently foster B. Placing of windows 1. Especially Patrol Rooms require windows to be placed sufficiently low to allow easy surveillance 2. Windows must facilitate surveillance also in sitting-down position C. Sense of safety: lighting & sight lines 1. Adequate lighting and clear sight lines instrumental to sense of safety 2. Crime safety surveillance distance: 25 135m max 3. Face recognition distance: 25m max 4. Person recognition distance: 135m max D. Rows of Trees 1. Consider trees not being placed where they will be an obstruction e.g. cutting out line of sight from pavilion behind E. Vandalism eg: occurance at Harare Square 1. Public Square should be done only after support structures/buildings are in place to enable surveillance 1.2 SURVEILLANCE & VISIBILITY 3. The Challenge: Practical Considerations & Possible Solutions: A. Disabled access 1. Access by physically challenged to upper floors 2. Cost and practicality issues make this most difficult B. Sense of clarity & comfort 1. Public environment to be free of obstructions and utilities C. Burglar guarding 1. Need secure burglar proofing to buildings generally, especially to trading facilities and storerooms 2. Additional considerations to be given to make trading facilities and storerooms burglar proof D. Adequate insulation in habitable rooms 1. Complaints have been received of cold interior to flats in winter 2. In line with sustainable principles flats must be insulated in accord with accepted good building practice E. Recreation facilities for younger children 1. Managing play spaces in partnership with crches to facilitate safe play F. Choices of recreational spaces 1. Recreation for passive & active activities, accommodating a range of age groups 2. Pleasant recreational spaces & seating required for groups/ individuals 3. Variety of spaces within shaded, public/quiet areas 1.3 COMMUNITY & PUBLIC SAFETY 4. The Challenge: Practical Considerations & Possible Solutions: A. Maintenance & repairs 1. Constant maintenance and immediate repairs to damaged elements contributes to positive sense of public environment B. Addition of new spaces/facilities in completed buildings 1. Retrofitting of additional floors/ accommodation has been necessary to several projects 2. Need for flexibility & resilience in all facilities 3. Complexity and high costs are associated with substantial retrofitting e.g. adding of additional floors and services C. Art Works 1. Opportunities to be explored for future artworks: Mosaic works, Sculptures, Metal screens 2. Managing facilities to prevent damage D. Financial sustainability of facilities 1. Each facility needs compelling purpose and adequate space to generate break-even income 2. Activities to be visible to enable presence within as well as surveillance onto surrounding territory E. Curtain Rails to Flats 1. Curtains/curtain rails/blinds to be provided by tenants subject to conditions in leases F. Designing for Community Functions eg: Kitchens 1. Size & position relative to meeting room(s)? 2. Space for food preparation? 3. Food is important part of community functions G. Wind problem in open mesh-screened spaces 1. Open mesh-screens to stairs & light boxes allow wind to blow through 2. Consider enclosing stairwells H. Store rooms/storage spaces 1. Secure/Lockable? 2. Sufficient storage to be provided for tables, chairs, cleaning equipment, materials, etc I. Cupboards 1. Adequate provision? 2. Secure/Lockable? 1.4 ADDITIONAL ITEMS 5. The Challenge: Practical Considerations & Possible Solutions: Pictures: A. Controlling movement of vehicles/off-loading 1. Vehicles often accidentally bump into landscaping elements e.g. seating, litterbins 2. Vehicles often obstruct trading activities & movement of people 3. Bollards limit acces to vehicles 4. Education/co-operation of drivers B. Permitting restricted access of vehicles 1. Service vehicles may require controlled access 2. Use of removable bollards where access is needed C. Preventing encroachment of private developments 1. Provide functional edge wall to define and hold boundary condition 2. Boundary definition/edge walling/ seating D. Off-loading by large trucks e.g. Harare Square 1. Difficulty for large truck to reverse into service yards 2. Requires large turning circles 3. Bollards may prevent damage to other landscaping elements but are likely to get damaged/bumped over Landscaping: Materials & Components 2.1 DEFINED ACCESS & SAFE MOVEMENT This section addresses how landscaping can be used to define access and movement in the interest of community & public safety with the use of physical barriers. The need for safe recreational space is explored & issues of maintenance & management of facilities as well as instances of vandalism are discussed. Furthermore, this section explores the different materials that can be used in landscaping & examines their strenghts and limitations. ! ! ! ! ! 6. The Challenge: Practical Considerations & Possible Solutions: Pictures: A. Play equipment- Risk of public liability in case of injury 1. Display signs to be placed at play equipment in local language stating that use of equipment is at own risk B. Safe choices of multi-functional play spaces/play parks 1. Variety of facilities needed at appropriate safe locations to provide for different age groups of children 2. Consider: Safety, Robustness, Low maintenance C. Lateritesports fields- Surface too rough for playing soccer 1. Surface possibly requires regular raking to remove larger stones. 2. Field extensively used anyway The Challenge: Practical Considerations & Possible Solutions: Pictures: A. Cracks in precast steps/junctions with paving 1. Cracks results in weeds growing through them which are unsightly 2. Ensure structural integrity 3. Fill movement joints with silicon sealant B. Borehole reliability 1. Disruption to borehole irrigation during peak summer months 2. Harvesting of rain water 3. Need for additional water storage tanks 4. Municipal auxiliary connection to top-up tanks are necessary 5. Possibly combination of various solutions is required C. Possible failure of booster pumps 1. Spare Booster Pump needed 2. Cost = approx R11 000.00/pump 2.2 RECREATIONAL FACILITIES 2.3 MAINTENANCE & MANAGEMENT ! ! ! ! ! 7. The Challenge: Practical Considerations & Possible Solutions: Pictures: A. Deliberate vandalism of pre-cast concrete benches 1. Precast concrete steps are difficult to repair 2. Also accidental damage e.g. chips; 3. Use more robust and thicker insitu castings 4. Occupydevelopments around public spaces as soon as possible to allow surveillance B. Vandalism of bubblers & sprinklers - pop-ups & valves 1. Need to identify alternative irrigation system due to vandalism 2. Potentially irrigate directly to roots which will facilitate growth 3. Bubblers to be placed below finished ground level C. Solenoid valves- unauthorized use 1. Unauthorised operation of valves 2. Place valves under lockable covers D. Stealing of bubblers 1. Informal traders believed to be tampering with irrigation system and removing bubblers in order to obtain water to wash fruit and vegetables 2. Provide communal tap for use by traders 2.4 VANDALISM ! ! 8. Material: Practical Considerations & Possible Solutions: Pictures: A. Tree cages (timber triangular cages and square cages) 1. Size to be adjusted to accommodate wider tree canopies 2. Optimal timber cage B. Tree cages (steel cages) 1. Detailing needs review due to buckling 2. Galv. Steel/timber cage C. Trees 1.
