The main stages of a project’s implementationPreliminary

DesignDetailed Design

Executive Design

Tender Works

The main purpose of the Preliminary Design is to define the dimensions of the structure, in order to obtain a clear picture of the structural action and make estimates of the project’s cost.

The main purpose of the Detailed Design is to define all the elements required to obtain the necessary permissions.

The main purpose of the Executive Design is to define all the details of the project in terms of costs and type of works.

The Tender stage refers to the period between the advertisement of the tender on public gazettes and the selection of the firm that will be contracted for the completion of the works.

The Works stage refers to the period between the handover of the site to the contractor and the completion of the works.

VISTO at a glance

A tool for:

selection

benchmarking

early-warning

performance assessment

VISTO is:

simple in its interface but based on predictive models built on complex data

transparent to stakeholders and citizens

universal for a “clinical diagnosis” of investment projects

VISTO: Application features VISTO yields an estimate of the time length of each

implementation stage of an investment project depending on its main attributes (cost, location, sector, type of project, category of implementing body, tender procedure).

VISTO yields the above estimates for each combination of attributes, regardless of whether such a project really exists or not.

Predictive models used for VISTO produce an estimate of the complete theoretical distribution of the time length of each stage: the median is chosen as central value and a variation interval is associated to it.

The length of each stage lasts until the start of the following one, except for the “Works” stage, ending at works completion.

VISTO: Panel description – Project features

The left-hand panel contains the project features that users can select interactively: the estimated length of each stage depends on the specific selected combination.

The available features are: amount, sector, type of project, category of implementing body, tender procedure, location at the provincial level.

The amount is the only quantitative feature and its value is typed in, all other features are selected with their combo box. Provinces are organised hierarchically and are selected within their region.

VISTO: Panel description – Length of stages

A button that produces a pdf output of the estimated lengths is available in the top right corner.

The upper part of the right-hand panel contains 5 dials where the estimated lengths of each of the 5 stages of a project with the selected features are represented together with some measures of the associated variability.

VISTO: Panel description – Dial elements

The black needle shows the estimated median value for the length of each stage, which is named “central length”.

The yellow band highlights a range of lengths, centred across the median value. The default width is set at 50% (25th-75th percentiles). The extremes are named “short” and “long” lengths.

The green sector marks the 35th percentile of the nationwide distribution (i.e. location is ignored) and can be used as a benchmark.

VISTO: Panel description – Overall project length

Below the summary chart, a green bar highlights the interval corresponding to the best 35% of projects with given features at national level, which may be considered as a benchmark.

The lower part of the right-hand panel contains a chart with the summary of the short, central and long lengths of the overall project, which are calculated as the sum of the lengths of the 5 stages.

VISTO: Potential users

A public officer can use VISTO as an additional tool for project selection during strategic planning of investments, or as an early-warning system in order to monitor the behaviour of on-going projects, or as an appraisal measure to evaluate the performance of a completed investment project.

A project manager can use VISTO to identify a reasonable target for his/her project, finding stimulus to push his administration towards the best practices at the national level.

A citizen can use VISTO to be aware on when a new public investment is most likely to be completed and available in his/her neighbourhood.

always classified correctly in monitoring

databases, but the proper classification

may be recovered from other fields.

1. Text-based clustering – The procedure (EM 5.2)

In Phase 1 data pre-processing is applied to a reference dataset where classification variables are known. It comprises the selection of project descriptions that can be used for the classification process (non-missing sector/type). Original description is enriched with sector description.Data are partitioned in a training and a test set (90-10).

Phase 1

Data pre-processing

PROJECT DESCRIPTIONS BY CATEGORY

DATA PARTITION

In Phase 2 the “textual” project descriptions of the reference dataset are transformed into a “numerical” space with the Text Miner Node. The Memory-Based Reasoning Node identifies similar cases by the k-NN algorithm and builds the classification model that can be applied to new cases.

Phase 2

Information processing

TEXT MINER MBR

In Phase 3 the Scoring Node allows the application of the classification model to new cases, i.e. project descriptions in the dataset that will be used for VISTO models.Classification is based on the proportion of “neighbours” of a new project description in each category (probability of classification).

2. Survival models

Advantages

The analytic estimates are based on a model that takes into account completed stages as well as on-going ones (censored cases) Maximise the use of available information on stage lengths

Offer a complete estimate of the survival function, i.e. the probability that the length of a certain stage is exactly t, given the values of the descriptive variables

2. Survival models – FormulationLet Ti be a random variable representing the (possibly unobserved) survival time of the i-th unit. Since Ti must be non-negative, its logarithm can be modelled using a conventional linear model:

where εi is a suitable error term, with a distribution to be specifed. This model specifes the distribution of log-survival for the i-th unit as a simple shift of a standard or baseline distribution represented by the error term.

In SAS this can be easily coded as follows:

iinnii xxT ...log 110

proc lifereg data=ds;class x2 x3;model y*cens(1)= x1 x2 x3;

output out=res p=median;run;

2. Survival models – The role of censored data

The length of censored stages is the output estimate of the model.

2. Survival models – The role of censored data

The width of the bars of the series “Only completed stages” is proportional to the ratio of “# completed” over “# completed and censored”.

The mean length of “Works” for the most costly projects increases by 20% when censored cases are included in the analysis. Their class (“More than 50 M€”) accounts for approx. 50% of the total financial value of all projects.

3. Does location matter?

Two approaches:

Territorial representation with highest available detail, economic interpretation of effects:• Descriptive variables at the provincial level

+ dummy variables at the regional level

Better economic and environmental conditions are associated with faster completion of the first two stages, which mainly deal with administrative permissions, while are associated with longer time spent in defining the fundamental details of the projects: longer durations may indicate greater accuracy and efficiency.There is also a positive correlation between “Crime against people” and the length of the “Works” stage.

VISTO, beside being an acronym, is also the Italian for “visa”: the idea is that a project whose stage lengths lie within the ranges indicated by VISTO can be acknowledged to specific benefits.
