Purpose This study investigates the carbon footprint of the alternative structure types and materials used for the reconstruction of schools in Haiti. Are recycled construction materials more environmental than virgin materials? To estimate which alternative construction solution has the smallest carbon footprint, a survey was made for the school model used for the reconstruction programme in Haiti after the 2010 earthquake. Design/methodology/approach The carbon footprint was calculated using life cycle assessment methodology for five different concrete structure alternatives and five different cement mixes for the same design of a school building. In addition, the uptake of CO2 through the carbonation of concrete during 50 years was calculated. Findings The carbon footprint of recycled materials can be either the best or worst option, depending on how the materials are used. The difference to using virgin materials is not big. This is mainly due to the lower structural performance of recycled materials, which needs to be compensated for by using additional reinforcements. Using cement mixes that have high amounts of substitutes for cement seems to lower the carbon footprint of structures considerably. The uptake of CO2 in carbonation has potential but requires an optimal design and environment. Originality/value The findings give information for humanitarian project managers and designers on lowering the carbon footprint of their construction projects.

The Cost

With the advent of awareness regarding carbon emissions and desirable reduction, this paper provides a calculator for the estimation of carbon footprint resulting from construction projects. For this purpose, we developed a software toolkit dubbed ‘Carbon Footprint Calculator for Construction Projects (CFCCP)’ capable of building a complete construction material database of carbon emissions. This is accomplished by accounting for wide range variables including construction size, landscape, and material construction. This calculator yields more accurate estimates as compared with other recently introduced calculators which consider only the general inputs of a certain project and produce estimates within ±25% accuracy. In this paper, the cost of the accuracy is accomplished via quality library variables such as project design plan, detailed bill of quantities (BOQ), and schedule timeline. The tool automatically outputs a detailed report describing the tasks and their associated carbon emissions which enables managers to take corrective measures to minimize these emissions before the onset of the project. Although the focus of this paper is on construction projects, the utilization of CFCCP may also be extended to other project types if database files for the project material can be built. For example, potential applications may involve the design of green buildings given that these kinds of buildings typically utilize materials from distant sources resulting in noticeable increase in their initial carbon footprint.

Capital Construction

The issues of determining the estimated cost of capital construction projects with the involvement of Federal budget funds at the stage of development of project documentation, during verification of the accuracy of determining the estimated cost and the initial (maximum) contract price are considered. On the basis of the assessment of amendments to urban planning legislation for the purpose of implementing a state contract by the contractor ( based on the results of competitive procedures or without competitive procedures by decision of state authorities), the procedure for forming the estimate as part of a state (municipal) contract, the price of which is firm, is presented. For the purpose of mutual settlements between the customer and the contractor for the work performed, the formation of primary accounting documentation, as well as for checking the work performed by regulatory authorities, an example of drawing up an estimate of the state (municipal) contract on the basis of grouping costs according to structural elements and complexes of work is given. The result of the research conducted was the development of regulations and the formation of criteria for their practical application by state bodies, institutions, organizations and other participants in the investment-construction process, as well as recipients of budget funds, who perform the functions of the state (municipal) customer, developer and technical customer.
