Such evaluation is a very complex task


Some tasks need not to be analyzed, as their
impacts/costs are approximately the same in
both approaches (design, demolition)


The
focus is on differences

between
traditional and TailorCrete approaches


WP8: Life cycle assesment of cost,
sustainability, safety and aesthetics

Task

objective:

To
compare costs between the traditional process and the TC for a specific
construction project.

T8.1 Life Cycle Cost


Traditional and TC processes: construction phase decomposition


Identification of partners to provide data.


Continuous process to gather information of the construction process in
terms of costs, resources, etc.


Identification
of tasks which do not need cost analyzed since they cost the
same (or with negligible differences) both in the traditional process or in the
TC process.

T8.1 Life Cycle Cost


Traditional and TC processes: construction phase decomposition


Identification of partners to provide data.


Continuous process to gather information of the construction process in
terms of costs, resources, etc.


Identification
of tasks which do not need cost analyzed since they cost the
same (or with negligible differences) both in the traditional process or in the
TC process.


Task

objective:

To
asses sustainability of TailorCrete concept, evaluate
product’s energy use,
and environmental carbon
, water, and waste
footprints.



The
same representative considered: Section of
Benidorm

wall


Prepared
extensive LCA data sheet for the partners to fill out.


Continuous
process to gather information of the construction process of the
Benidorm

Wall (
CAD
files, Costs,
Materials, Resources and construction
processes followed).


GaBi

software evaluated, facilitating investigation and comparison of environmental
impacts of a process, material or building work.


LCA Database with the cost, energy and environmental impact data






T8.2 Life Cycle Analysis

Task

objective:

To make sure that TC concept will not worsen existing safety concerns.
Existing
safety issues should be improved, if possible
.



Developed
material data sheets

and
safety questionnaire


The open literature and project materials reviewed (DLs, Reports)


Currently
data analysis under progress to identify possible safety issues and
to propose possible solutions.

T8.3
Safety in the life cycle


Material data sheet


Document with information on the potential hazards (health, fire,
reactivity, and environmental) of any material


Including description on composition, handling , and work safety of the
product



Example: Wax


N
ot a new material, but its processing requires melting
-
> possible
risk for workers
-
> protective gear recommended.




The electronic version of this questionnaire can be downloaded from
http://mech.fsv.cvut.cz/TC

T8.3 Safety in the life cycle


Safety questionnaire


Structured
according to individual life cycle phases


Focused
on identification of new safety issues
during
individual phases.


Recommendations
to how possible or existing safety problems can be eliminated
.


Collected results (6 partners contributed)


Example: Fibers


Service life:
-
> improvement of safety (improved ductility
-

earthquakes, polypropylene fibers
-

spalling

prevention)


Production: need for quality control (dosage)
-
> solved for steel fibers, still open for
polypropylene



T8.3
Safety in the life cycle

The electronic version of this questionnaire can be downloaded from
http://mech.fsv.cvut.cz/TC

Task
o
bjective:

To
assess the aesthetic factors (smoothness, texture, surface
deterioration)
using
accelerated
tests


Accelerated testing allows to
simulate in a short period time the expected performance
of cement specimens exposed to different environmental
conditions.


11
samples for accelerated aesthetic evaluation have been received from project
partners


Concrete
tiles of eleven different conventional or SCC recipes have been casted
following the same procedure in different laboratories with similar hydration
time


Carried
out
colour measurements during a preliminary conditioning period





T8.4 Aesthetic evaluation





Due to delays in delivery of some samples, the completion of the
accelerated ageing tests will have
been
postponed 2
months


A draft of DL8.4 will be prepared for 31
st

of January 2013 with the
preliminary results and conclusions from the accelerated ageing
tests.


The final DL8.4 will be submitted by 1
st

of April 2013 and uploaded
to ECAS.

WP8
Future Planning

Tasks 8.1 and 8.2: (LCA+LCC)


1.
Considered postponement of DL8.1 and DL8.2 to perform LCA and LCC
directly on demonstrator project.

1.
Higher impact to project

2.
Results more valuable and solid


Task 8.3: (Safety)


Final communication with partners to propose solution on how to improve
identified issues


DL 8.3 will be on time.


Task 8.4: (Aesthetics evaluation)


Accelerated testing of received samples and their evaluation in progress.
