Annex I 14 Criteria for the formation and updating of regional price lists.

(Article 41, paragraph 13)


Article 1.

General information

1. The regional price lists are drawn up pursuant to article 41, paragraph 13, of the code by the territorially competent regions and autonomous provinces, in agreement with the territorial branches of the Ministry of Infrastructure and Transport. This annex contains indications for the determination of price lists, respecting the organizational autonomy of each region and autonomous province, promoting the homogeneity of the relevant training and updating criteria. The price list operates as a tool to support the entire public procurement chain, in order to guarantee the quality of public works, safety on construction sites and the appropriateness of the cost of the works, taking into account the specificities of the production systems of the individual regions.

2. To ensure maximum transparency and the public support function, the price lists are made available free of charge on institutional websites, with particular regard to the website of the competent region or autonomous province and of the Ministry of Infrastructure and Transport through the Public Contracts Service ( SCP), together, where possible, with the analytical description which leads to the definition of the cost of the work to be carried out. Without prejudice to the designer's skills regarding the correct definition of the composition of the cost of a work, the decision to make the system of formation of this cost public intends to promote maximum transparency with respect to the methodology for defining the published price. For the purposes of this paragraph, the regional price lists are made available in open data format.

3. In order to ensure the homogeneity of the criteria for forming and updating the price lists, this annex contains indications relating to:

a) the structuring and articulation of the price lists, also providing for the use of common definitions for guarantee, in compliance with territorial and product specificities, greater usability and possibility of comparison of regional price lists;

b) the construction of an information system to be placed at the service of the construction sector at a national level, which allows the comparison and usability of the contents of the price lists in terms of prices, resources and technical standards of reference;

c) the survey methodology, with references to the subjects from whom the information should be collected and the survey methods;

d) the timing and methods for updating the price lists in implementation of this annex and for the progressive publication of the analysis;

e) organizational aspects concerning the coordination between the regions and autonomous provinces and the Ministry of Infrastructure and Transport in order to define detailed instructions for the standardization of price lists and the systematization of common skills. p>

4. The definition of the detailed instructions relating to paragraph 3, letters a), b), c) and d) is entrusted to the coordination table referred to in article 6 composed of representatives of the regions, within the regional price list network, and of the Ministry of Infrastructure and Transport. Pending the conclusion of this process, the price lists in force maintain their effectiveness and validity and the extraordinary update provided for by article 26 of the legislative decree of 17 May 2022, n. 50, converted, with amendments, by law 15 July 2022, n. 91, can be carried out with the previous methodology and procedures.


Article 2

< p>Structure and contents of the price list

1. The reference price list is codified in terms of processes and resources. The term "works" means the result of a set of works necessary to carry out a work which in itself performs an economic or technical function, including those of environmental protection and defence.

2. The processes are classified according to "subsequent levels" and the succession of the elements that compose them follows the structure of the production process. As an indication, these levels can be classified into:

a) typology: identification of processes based on their functions and technological characteristics, mainly used for the construction of certain works;

b) chapter: segment of an organizational nature within the classification of activities;

c) item: subordinate classification to the chapter;

d) article: classification subordinate to the item.

3. The term "resource" means a cost element that constitutes a production factor in a job, a supply or a service. The resources, in turn, can be divided into:

a) family: identification of human resources, products and equipment, based on the works and activities, in particular :

1) human resource: work production factor, such as human physical or intellectual activity (in common terminology the term labor is used);

2) equipment: capital production factor which includes capital goods, machines, vehicles, freight, transport, etc. (in common terminology, terms such as freight and transport are used);

3) product: result of a man's productive activity, technically and economically defined; by extension also any raw materials used directly in the construction production activity;

b) chapter: segment of an organizational nature within the classification of activities;

< p>c) item: classification subordinate to the chapter;

d) article: classification subordinate to the reference item.

4. In order to correctly apply what is contained in the price lists, the general rules indicate the rules for measuring the work, the indications on the general expenses and the analysis criteria to be applied, as well as any increases to be applied in specific conditions that could arise from the needs of particular territories .

5. By way of example, a possible price list organization scheme is shown in Table A attached to this annex.

6. For the purposes of creating the information system referred to in article 1, paragraph 3, letter b), the transcoding codes that relate the contents of the regional price lists are constructed using an alphanumeric code, with identification and ordering functions, divided into multiple levels and containing a "prefix", which indicates the region or autonomous province to which it belongs, as reported in Table B attached to this annex and a two-digit number indicating the year to which the prices refer (22=2022 ; 23=2023; 24=2024; etc.). The prefix must also provide the possibility of identifying the price list and its possible update during the year.

7. In price lists, the price list items are progressively drawn up according to coding methodologies that allow direct interaction with information modeling (BIM) methods and tools. The coding may involve the insertion of a text string which allows, through a series of tags, the automatic use and transfer of both the price items and the metadata associated with each process in the digital management processes of the design. The definition and construction of the transcoding method and information system as well as the indications on the progressive adaptation of price lists to a direct interaction with the information modeling methods and tools (BIM) is delegated to the Coordination Table referred to in Article 6. < /p>


Article 3

Resource prices and survey methodology


1. The item relating to resources in the regional price lists includes human resources, equipment and products. This article reports the procedures and references for assigning the price of these resources. With the exception of human resources, for other resources the price is determined on the basis of a survey of the costs of products and equipment carried out in the area using the methodologies reported in paragraphs 5 to 12.

2. The costs of human resources are defined through the cost of labour, which is determined annually, in specific tables, by the Ministry of Labor and Social Policies on the basis of the economic values defined by national collective bargaining between trade unions and employers' organisations. comparatively more representative work, of the rules on social security and welfare, of the different product sectors and of the different territorial areas. In the absence of the reference in the table, reference is made to the specific applicable collective agreement. In the absence of an applicable collective agreement, the cost of labor is determined in relation to the collective agreement of the product sector closest to the one taken into consideration. annually by the Ministry of Labor and Social Policies, and reported in specific tables. This cost refers to work carried out during ordinary hours and, therefore, the percentage increases foreseen for overtime, night or holiday work are not included.

3. The cost of the equipment, technically defined as "rental", is determined through a survey carried out following the methodologies reported in paragraphs 5 to 12. It is divided into "cold rental" and "hot rental" based on the costs included in it, according to the following definitions:

a) cold rental: the cold rental of the work vehicle or equipment does not include, unless otherwise specified, the costs of the labor necessary for its use, the expenses for consumables (fuel, lubricants, etc.) and normal maintenance and third party insurance;

b) hot rental: includes the costs of the labor necessary for its use, the expenses for consumables (such as fuel or lubricants), normal maintenance and third party insurance. Any repairs and related hours of machine downtime are the responsibility of the economic operator, as a contracting party with the contracting authority.

< p>4. The costs of the products, determined following the methodologies reported in paragraphs 5 to 12, concern the supply of products, including construction products, compliant with what is required by current legislation. The reference price of the products includes all costs deriving for the contractor from the relevant supply ex-worksite, including the cost of transport.

5. Cost recording is the activity through which information and data relating to the costs of individual products and equipment are acquired. These data are subsequently processed in order to obtain a representative value of the final price, obtained by adding the value of general expenses and business profits to the sum of all costs. The technical specifications of the products and equipment subject to survey and inclusion in the price list must comply with the requirements and limitations established by current legislation, with particular reference to the provisions of article 79 of the code.

6. The survey methodology to be used is, as a priority, the "direct" one, which involves the acquisition of data and information directly from the actors in the construction supply chain. The survey is carried out in compliance with statistical confidentiality, currently protected, in particular, by article 9 of legislative decree 6 September 1989, n. 322, so as to guarantee the anonymous circulation of data between the subjects involved in various capacities in the price list approval procedure. As part of the cost recording procedures, in the presence of personal data, they are acquired in compliance with the rules on the protection of personal data as regulated by Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 ( GDPR-General Data Protection Regulation), also ensuring compliance with the principles of necessity, relevance and non-excess, in order to limit the processing to those personal data that are actually indispensable with respect to the objectives pursued. The survey activity allows the reliable acquisition of data and minimum information capable of constituting a representative reference of the cost of a product or equipment. The object of the survey contains:

a) a precise description of the product or equipment subject to the survey, including references to technical standards or product specifications where applicable, and information useful for a possible conversion into different units of measurement;

b) the price list, where present, official and in force in the survey period, explicitly reporting the item relating to the product or equipment being surveyed with the relative price ;

c) evidence regarding the average discounts applied (compared to the current list price) to the product or equipment considered in the survey period;

d) suitable proving documentation the compliance of the product with the minimum environmental criteria (CAM).

7. The selection of the informants involved in the survey activity is carried out in compliance with the following requirements:

a) the survey must be directed at selected economic operators (informants) who are part of the construction sector supply chain, from production to the resale or warehouse chain;

b) the informants, distinguished on the basis of the product-territorial areas of operation and the different role in the procurement chain, must preferably be located and operational in the regional territory;< /p>

c) for each product or equipment for which the survey is carried out, where the market allows, a suitable and representative number of operators must be available.

8. Each region or autonomous province can activate further actions to control the quality of the data provided by the informants. The procedure for recording costs and acquiring the necessary data and information is divided into the following phases:

a) the selection of informants, identified according to the requirements listed above;

< p>b) the transmission of the request for the data and information to be provided, in compliance with statistical confidentiality, Regulation (EU) 2016/679 and the digital administration code, referred to in Legislative Decree 7 March 2005, n. 82;

c) the processing and verification of the data and information acquired;

d) the reporting of the activity.

9. The survey period takes place by ensuring that the cost acquisition activity is concluded by October 31st in order to have the most up-to-date information possible and allow a timely update of the price list by December 31st of the year preceding the reference year. . In any case, without prejudice to the timing and methods resulting from any updates during the year, to the outcome of the monitoring carried out by the regions and autonomous provinces, in accordance with the provisions of article 6.

10 . The Infrastructure, Mobility and Territorial Government Commission of the Conference of Regions and Autonomous Provinces makes use of the Institute for Innovation and Transparency of Procurement and Environmental Accounting (ITACA) to promote the monitoring of the costs of a specific list of more relevant and of greater use.

11. The monitoring of the most relevant products is aimed at ensuring a greater exchange of information between the regions, also with a view to reducing any discrepancies in the survey method and published prices, as well as allowing intra-annual monitoring of the evolution of material costs, in contexts characterized by marked and sudden changes in the costs of products and equipment. To this end, the monitoring activity ends with the publication of a summary document, drawn up in the form of a table, which for each product or equipment subject to monitoring, indicates:

a) the description of the product or equipment;

b) the unit of measurement;

c) the cost recorded by each region and autonomous province, net of general expenses (variable from 13 to percent to 17 percent), business profit (10 percent) and VAT;

d) any notes.

12. The table referred to in paragraph 11 allows the analysis of the average values, as well as the dispersion at a territorial level for the products considered. The comparison of the aforementioned table in different periods also allows us to highlight the percentage changes of each individual item compared to the previous period.

13. At the end of the phase of checking the data and information acquired, the reference price is determined, which is subject to approval for the purposes of its publication in the price list. The reference price is calculated starting from the data and information acquired, through retraceable analytical methodologies, and is parameterized to the simple average. When the data collected is characterized by high dispersion or the presence of anomalous values, alternative synthetic indicators can be used, such as the use of the median, the weighted average (for the size of the informant) or the elimination of anomalous data. All published prices are exclusive of VAT.


Article 4

Objective scope of application and validity

1. The price lists drawn up by the regions and autonomous provinces in agreement with the territorial branches of the Ministry of Infrastructure and Transport must be used for the purposes of definitively quantifying the spending limit for the construction of a work. The consultation between each region or autonomous province and the corresponding territorial branch of the Ministry of Infrastructure and Transport takes place when the price list is drawn up through the participation and expression of the opinion of representatives of the interregional authority for public works territorially competent in the scope of the work carried out by the bodies or technical tables or commissions established for this purpose by the regions or autonomous provinces.

2. The price lists cease to be valid on December 31st of each year and can be temporarily used until June 30th of the following year for tender-based projects whose approval has occurred by that date, i.e.:

a) in the case of a technical-economic feasibility project to be the basis of the tender, if the same project is approved by 30 June, it is possible to use the price list in force in the previous year for the purpose of quantifying the spending limit; after 30 June, the project to be the basis for the tender will be reviewed using the current price list;

b) in the case of an executive project to be the basis for the tender, if the same is approved by June 30, the price list approved with the previous project level is used; in the event that further prices are necessary, they may be deducted from the price list in force in the previous year.

3. The approval deadline referred to in paragraph 2, letters a) and b), refers to the date of adoption of the act of approval of the project used as the basis for the tender.

4 . The published prices refer exclusively to the interventions as described and relate to construction sites with normal execution difficulties. Unless otherwise indicated, they do not include the amounts relating to any connected or complementary works, essential for the execution of the works described. Such additional amounts must be determined and calculated separately.

5. Without prejudice, where permitted and authorised, to the publication of the price list in different forms, the official version is exclusively the one published in the Regional Official Bulletin (BUR), on the website of the competent region or autonomous province and of the Ministry of Infrastructure and Transport via the Public Contracts Service (PSP).


Article 5

The determination of the price based on tender

1. The tender price of the works to be carried out is calculated on the basis of the estimated metric calculation which includes the indication of the work, the relative quantifications and the relative unit prices. The unit price of each process is obtained by resorting to the analytical description of the activities to be carried out, and attributing to the resources used the costs determined with the methodologies described in article 3. The analyzes refer to processes carried out in conditions of normal difficulty in execution. The analytical description leading to the definition of the cost of the work to be carried out is made public and available for consultation according to the instructions defined by the coordination table referred to in article 6.

2. Price analysis is a procedure through which the value of a process is obtained by defining its components and the implications necessary for the realization of the work, elaborated on the basis of the following factors:

a ) first direct cost or technical cost (CT) broken down as follows:

1) cost per unit of labor time (RU);

2) cost per unit of measurement of products to be construction (PR);

3) cost per unit of time of equipment (AT);

b) indirect cost consisting of general expenses (defined between 13 percent and 17 percent) (SG);

c) notional cost (U):

1) business profits equal to 10 percent (U) .

3. The price is determined through the following analysis operations:

a) applying the respective elementary costs to the quantities of products, equipment and human resources necessary for the creation of the unit quantities of each item;

< p>b) adding the percentage for overheads;

c) adding a percentage of 10 percent for the performer's profit.

4. The processing price is obtained by considering the following expression:

𝑃𝑜 = 𝐶t + 𝑆𝐺 +𝑈


𝐶t = (𝑎) + (𝑏) +(𝑐 ;);

𝑆𝐺 = (0.13÷ 017) × 𝐶t;

𝑈 = 0.10 × (𝐶t +𝑆𝐺).

The price of the processing is given by the following relation

𝑃𝑜 = (1.243 ÷ 1.287) × 𝐶t.

5. As part of the price list, for each price the relevant analysis is indicated or can be consulted, where available, through a gradual publication process, in accordance with the provisions of article 1.

4. During the price list management and updating phases, where necessary, we proceed with the qualitative and quantitative verification of the resources used, in order to adapt and keep the analyzes updated to the most current technologies and regulations. In the analyses, it is possible to highlight the percentage impact of resources, with particular reference to human resources, and the impact of corporate safety costs. The impact of a resource is calculated as the ratio between the overall cost of the same resource (human resource, products or equipment) and the reference cost of processing. All published prices are exclusive of VAT.

5. Pursuant to Article 31 of Annex I.7 to the code, "general expenses included in the price of the works", to be paid by the executor, mean:

a) contract and ancillary expenses and registration tax;

b) general and specific financial charges, including the definitive deposit or global performance guarantee, where applicable, and insurance policies;

c) the share of the costs of organization and technical-administrative management of the executor's headquarters;

d) the administrative management of the construction site staff and the technical management of the construction site;

e ) the costs for the installation, maintenance, lighting and final folding of the construction sites, including the costs for the use of areas other than those made available by the client; expenses relating to safety on the construction sites themselves which are not subject to a discount are excluded;

f) expenses for the transport of any material or means of construction;

g) expenses for tools and temporary works and anything else necessary for the full and perfect execution of the works;

h) expenses for surveys, layouts, checks, explorations, cornerstones and the like that may be necessary, also upon a reasoned request from the director of works or the RUP or the testing body, from the day on which delivery begins until the completion of the provisional testing or the issuing of the certificate of regular execution;

i) expenses for access roads to the construction site, the installation and operation of construction site equipment and vehicles;

l) expenses for suitable premises and for the necessary equipment to be made available for the works management office;

m) expenses for the passage, for temporary occupations and for compensation for damages due to the felling of plants, storage or extraction of materials;

n) the costs for the safekeeping and good conservation of the works until the issuing of the provisional testing certificate or the issuing the certificate of regular execution;

o) the costs of adapting the construction site in compliance with the legislative decree of 9 April 2008, n. 81, of which the share of impact on the total general expenses is indicated, for the purposes of the obligations envisaged by article 110, paragraph 5, letter c), of the code;

p) general and particular charges provided for in the special tender specifications.

6. The elementary resources provided for in the price list are used to compose the new analyses. The designer remains entitled to formulate additional prices, following a specific price analysis, in cases where the reference price list does not include a process envisaged in the project.

7. The items that contribute to the determination of general expenses, pursuant to article 31 of annex I.7 to the code, include all possible arrangements connected to individual processes, as they are instrumental to the execution of the works and contribute to the formation of individual categories of work. The corporate safety costs connected to the specific risks inherent to business activity, pursuant to legislative decree n. 81 of 2008, are included, as they represent an obligation to protect the safety of workers on the part of the employer, within the scope of the general expenses recognized in each price list article and not directly attributable to the cost items contemplated in the annex XV, point 4, of legislative decree no. 81 of 2008. According to the provisions of article 31, paragraph 4, of annex I.7 to the code, the aforementioned charges are included in the unit price of the individual processing, and therefore in the cost of the work, contributing to a portion of the expenses general themselves. The designer of the work and the safety coordinator carry out the planning in a coordinated manner in order to identify in the Safety and Coordination Plan (PSC) the safety costs not included in the unit price of the single process, referred to in point 4 of the annex XV to legislative decree no. 81 of 2008, not to be subject to reduction.

8. The term "safety costs" means the cost of safety indicated in the following project documents:

a) safety and coordination plan (PSC) referred to in article 100 and point 4 of the annex XV to legislative decree n. 81 of 2008;

b) single interference risk assessment document (DUVRI);

c) estimate of the contracting authority if the PSC is not foreseen pursuant to point 4.1. 2 of Annex XV to Legislative Decree no. 81 of 2008.

9. The articles contained in the "Safety" typology (legislative decree no. 81 of 2008), if included in the project documents listed above, represent the portion of the cost of a work not to be subjected to a reduction in the bids of companies. As part of the process of adapting the regional price list to this annex, the related amounts include only the share relating to general expenses (from 13 percent to 17 percent). The share of company profit (10 percent) is always excluded as safety costs are not subject, by law, to a reduction in the auction when submitting bids. The contents of this typology are indicative of the possible measures aimed at safety, without prejudice to the further project forecasts or operational sector requirements, foreseen in the specific safety project document and directly estimable through the pre-existing cost items in the other types of price list. In the cases referred to in the fourth period, the published price is recalculated, separating the 10 percent profit share from it, for consistency with what was done with the "Security" type prices. The costs thus estimated are not subject to a reduction and are recognized for the quantities executed.

10. Any use of the items contained in the "Safety" type for processes not specifically aimed at safety involves a preventive increase in the cost values provided by the relative share of profit, with a multiplication coefficient equal to one point ten, and the values thus estimated are subject to a discounted auction.


Article 6

< p>Organization and coordination activities

1. In compliance with regional organizational autonomy, in order to allow an effective and organized price list formation system, the regions equip themselves with an organizational model, inspired by principles of simplification and promotion of the efficiency of administrative action, which guarantees compliance of the principle of impartiality in the adoption of acts, such as the price list, which involve potentially conflicting public and private interests.

2.It is established at the Ministry of Infrastructure and of transport a coordination table made up of five representatives of the regions and autonomous provinces, identified within the activities of the price list network, including one representative of ITACA, and five representatives of the Ministry of Infrastructure and Transport , with the following functions:

a) recognition of the status of regional price lists in order to plan the progressive implementation of this annex;

b) updated definition of the most relevant products and related units of measurement on which to share the monitoring activity;

c) sharing the results of the monitoring activity on the costs of the most relevant products, following a specific survey on a regional basis;

d) definition of criteria and methods for the possible early revision of price lists, in the face of exceptional variations in some more relevant materials, and for the publication of the analyses;

e) sharing, with reference to the structuring and articulation of the price list referred to in article 1, of contents and resources in order to homogenize and standardize a significant set of common items;

f) definition and implementation of the method and information system of transcoding, classification and application cooperation, which allows the comparability of price lists, as well as indications on the progressive adaptation of price lists to a direct interaction with information modeling methods and tools (BIM);

g) sharing of
