The problem is that, in many cases, they are not responding to exactly the same scope. One proposal may include installation, testing, documentation, and support. Another may exclude important parts. A third may look cheaper but transfer risks, interfaces, and responsibilities to the client.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why <strong>engineering technical proposal analysis<\/strong> should not be limited to price. The lowest initial price may hide scope gaps, weak assumptions, low technical quality, missing tests, incomplete documentation, an unrealistic schedule, or a high risk of change orders.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A sound technical analysis allows proposals to be compared objectively, risks to be identified, differences to be leveled, and a safer contracting decision to be supported.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In critical projects, this analysis can prevent rework, stoppages, contractual disputes, and deliveries that fail to meet the client\u2019s objective.<\/p>\n\n\n\n<h2 id=\"h-por-que-o-menor-preco-nao-deve-ser-o-unico-criterio\" class=\"wp-block-heading\">Why should the lowest price not be the only criterion?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Price is an important criterion. No client should ignore budget, CAPEX, cash-flow timing, or commercial conditions. The problem arises when price is analyzed in isolation, without verifying whether the proposals are technically equivalent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In engineering services, two proposals with the same title may contain completely different scopes. One may include detailed design, installation, configuration, commissioning, and training. Another may cover only equipment supply. Comparing only the total price in that case leads to a distorted decision.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Decision based only on lowest price<\/th><th>Technical risk<\/th><\/tr><\/thead><tbody><tr><td>Ignoring proposal exclusions<\/td><td>Incomplete scope and future change orders<\/td><\/tr><tr><td>Not comparing assumptions<\/td><td>Apparently equivalent proposals may be different<\/td><\/tr><tr><td>Not assessing technical capability<\/td><td>Supplier may fail to execute with quality<\/td><\/tr><tr><td>Not considering maintenance<\/td><td>Higher operating cost over the life cycle<\/td><\/tr><tr><td>Not analyzing risks<\/td><td>Delays, rework, and contractual conflicts<\/td><\/tr><tr><td>Not verifying documentation<\/td><td>Difficulty with technical acceptance and future operation<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The article on <a href=\"https:\/\/a3aengenharia.com.br\/conteudo\/artigos-tecnicos\/menor-valor-global-servicos-engenharia-paralisacoes-aditivos\/\">lowest total price in engineering services<\/a> examines this risk in greater depth. Here, the focus is on how to evaluate a proposal technically before contracting.<\/p>\n\n\n\n<h2 id=\"h-o-que-e-uma-proposta-tecnica-de-engenharia\" class=\"wp-block-heading\">What is an engineering technical proposal?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An <strong>engineering technical proposal<\/strong> is the response from a supplier, consultant, integrator, designer, or contractor to a client\u2019s technical need.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It should demonstrate how the supplier intends to meet the scope, which solutions will be adopted, which assumptions were considered, which deliverables will be provided, which responsibilities are included, and which criteria will be used to validate the delivery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An engineering technical proposal may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>understanding of the scope;<\/li>\n\n\n\n<li>proposed technical solution;<\/li>\n\n\n\n<li>execution methodology;<\/li>\n\n\n\n<li>technical team involved;<\/li>\n\n\n\n<li>schedule;<\/li>\n\n\n\n<li>materials, equipment, or software;<\/li>\n\n\n\n<li>assumptions adopted;<\/li>\n\n\n\n<li>exclusions;<\/li>\n\n\n\n<li>client responsibilities;<\/li>\n\n\n\n<li>warranties;<\/li>\n\n\n\n<li>final documentation;<\/li>\n\n\n\n<li>testing, commissioning, and acceptance;<\/li>\n\n\n\n<li>support and maintenance;<\/li>\n\n\n\n<li>risks or conditions.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The more critical the project, the greater the level of detail that should be required.<\/p>\n\n\n\n<h2 id=\"h-o-que-significa-analisar-tecnicamente-uma-proposta\" class=\"wp-block-heading\">What does it mean to analyze a proposal technically?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Analyzing a proposal technically means verifying whether it meets the client\u2019s objective, the scope, technical requirements, implementation conditions, environmental constraints, quality criteria, risks, and acceptance conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is not enough to confirm that the supplier mentioned all items in the Terms of Reference. The analysis must assess whether the solution is coherent, executable, compatible with the environment, and sufficient to produce the expected delivery.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Technical question<\/th><th>What to assess<\/th><\/tr><\/thead><tbody><tr><td>Does the proposal meet the scope?<\/td><td>Compliance with the Terms of Reference, basic design, or specification<\/td><\/tr><tr><td>Is the solution suitable?<\/td><td>Technology, performance, compatibility, and limitations<\/td><\/tr><tr><td>Can the supplier execute?<\/td><td>Team, experience, certifications, methodology, and resources<\/td><\/tr><tr><td>Are there relevant exclusions?<\/td><td>Items outside the price or under the client\u2019s responsibility<\/td><\/tr><tr><td>Is there a risk of change orders?<\/td><td>Gaps, ambiguities, weak assumptions, and open interfaces<\/td><\/tr><tr><td>Will the delivery be verifiable?<\/td><td>Tests, evidence, documentation, commissioning, and technical acceptance<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This analysis is often a practical application of <a href=\"https:\/\/a3aengenharia.com.br\/conteudo\/artigos-tecnicos\/engenharia-consultiva-vs-consultoria-tecnica\/\">consulting engineering<\/a>, because it transforms a contracting decision into a structured technical process.<\/p>\n\n\n\n<h2 id=\"h-criterios-minimos-para-analise-de-proposta-tecnica-de-engenharia\" class=\"wp-block-heading\">Minimum criteria for engineering technical proposal analysis<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A consistent evaluation should consider technical, commercial, operational, and risk criteria.

This may be a Terms of Reference document, a basic design, a technical specification, a requirements matrix, an RFP, or a descriptive technical memorandum.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without a clear baseline, the evaluation becomes subjective. The supplier may claim it delivered what it understood. The client may argue that it expected something different. This difference in interpretation often leads to change orders, delays, and disputes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, the analysis should verify:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>mandatory requirements met;<\/li>\n\n\n\n<li>desirable requirements met or not met;<\/li>\n\n\n\n<li>unanswered items;<\/li>\n\n\n\n<li>technical deviations;<\/li>\n\n\n\n<li>proposed alternatives;<\/li>\n\n\n\n<li>exclusions;<\/li>\n\n\n\n<li>assumptions;<\/li>\n\n\n\n<li>planned documentation and testing;<\/li>\n\n\n\n<li>acceptance criteria.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When the reference scope is weak, the first step may be to review the <a href=\"https:\/\/a3aengenharia.com.br\/conteudo\/artigos-tecnicos\/o-que-e-projeto-basico\/\">basic design<\/a> or apply a <a href=\"https:\/\/a3aengenharia.com.br\/conteudo\/artigos-tecnicos\/checklist-projeto-basico-antes-de-licitar-contratar-obra\/\">basic-design checklist before contracting<\/a>.<\/p>\n\n\n\n<h2 id=\"h-equalizacao-tecnica-como-comparar-propostas-diferentes\" class=\"wp-block-heading\">Technical leveling: how to compare different proposals<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Technical proposals rarely arrive in the same structure. One supplier details tests; another does not. One includes documentation; another omits it. One includes integration; another treats it as outside the scope. Technical leveling organizes these differences to enable a fair comparison.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The objective is to compare proposals on the same basis, identifying what is included, excluded, conditional, or undefined.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Element<\/th><th>Proposal A<\/th><th>Proposal B<\/th><th>Proposal C<\/th><th>Technical observation<\/th><\/tr><\/thead><tbody><tr><td>Included scope<\/td><td>Complete<\/td><td>Partial<\/td><td>Complete<\/td><td>B excludes installation<\/td><\/tr><tr><td>Testing<\/td><td>FAT + SAT<\/td><td>SAT<\/td><td>Not stated<\/td><td>C must clarify testing methodology<\/td><\/tr><tr><td>Warranty<\/td><td>12 months<\/td><td>24 months<\/td><td>12 months<\/td><td>B has a commercial advantage<\/td><\/tr><tr><td>Final documentation<\/td><td>Complete<\/td><td>Partial<\/td><td>Complete<\/td><td>B does not mention as-built documentation<\/td><\/tr><tr><td>Support<\/td><td>8&#215;5<\/td><td>24&#215;7<\/td><td>Not stated<\/td><td>C has no defined SLA<\/td><\/tr><tr><td>Integrations<\/td><td>Included<\/td><td>Excluded<\/td><td>Partial<\/td><td>High risk of change orders in B and C<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This matrix makes it clear that the cheapest proposal may not be the most advantageous when scope, risk, and life cycle are considered.<\/p>\n\n\n\n<h2 id=\"h-como-montar-uma-matriz-de-avaliacao-tecnica\" class=\"wp-block-heading\">How to build a technical evaluation matrix<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A technical evaluation matrix helps compare suppliers objectively. It should be defined before the analysis, with clear criteria, weights, and scoring methods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The weights need to reflect the type of contracting. A critical system may require greater weight for testing, support, experience, and risk. A consulting service may require greater weight for methodology, team, and specific experience.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Criterion<\/th><th>Weight<\/th><th>Supplier A<\/th><th>Supplier B<\/th><th>Supplier C<\/th><\/tr><\/thead><tbody><tr><td>Scope compliance<\/td><td>25%<\/td><td>8<\/td><td>6<\/td><td>9<\/td><\/tr><tr><td>Technical solution<\/td><td>20%<\/td><td>7<\/td><td>8<\/td><td>9<\/td><\/tr><tr><td>Experience and team<\/td><td>15%<\/td><td>8<\/td><td>7<\/td><td>6<\/td><\/tr><tr><td>Schedule<\/td><td>10%<\/td><td>7<\/td><td>9<\/td><td>7<\/td><\/tr><tr><td>Testing and acceptance<\/td><td>10%<\/td><td>8<\/td><td>5<\/td><td>9<\/td><\/tr><tr><td>Support and warranty<\/td><td>10%<\/td><td>6<\/td><td>9<\/td><td>7<\/td><\/tr><tr><td>Risks and assumptions<\/td><td>10%<\/td><td>7<\/td><td>6<\/td><td>8<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Scoring should not replace technical judgment.

In engineering, the total cost of the solution over time must be assessed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The concept of <strong>Value for Money<\/strong>, used in international procurement guidance, considers the best combination of total cost, quality, and fitness for the buyer\u2019s objective. This is especially relevant when the solution involves maintenance, operation, support, energy, licenses, spare parts, expansion, or the risk of downtime.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Cost type<\/th><th>Example<\/th><\/tr><\/thead><tbody><tr><td>CAPEX<\/td><td>Equipment, installation, licenses, design, and implementation<\/td><\/tr><tr><td>OPEX<\/td><td>Support, maintenance, energy, staff, and monitoring<\/td><\/tr><tr><td>Life-cycle cost<\/td><td>Replacements, upgrades, parts, and expansion<\/td><\/tr><tr><td>Risk cost<\/td><td>Failures, delays, change orders, rework, and poor quality<\/td><\/tr><tr><td>Downtime cost<\/td><td>Operational stoppage, loss of security, impact on SLA or continuity<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">A technically stronger proposal may have a higher initial price but reduce total cost, risk, and operating effort.<\/p>\n\n\n\n<h2 id=\"h-criterios-eliminatorios-x-criterios-pontuaveis\" class=\"wp-block-heading\">Mandatory criteria vs. scored criteria<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not every criterion should be treated in the same way.

But they indicate that clarification is needed before contracting.<\/p>\n\n\n\n<h2 id=\"h-quando-pedir-esclarecimentos-tecnicos-ao-fornecedor\" class=\"wp-block-heading\">When should technical clarifications be requested from the supplier?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Clarification requests are an important part of engineering technical proposal analysis. They reduce ambiguity and prevent decisions from being made on assumptions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples of useful questions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Confirm whether installation is included in the scope.<\/li>\n\n\n\n<li>State the brand, model, and specification of the equipment considered.<\/li>\n\n\n\n<li>Specify which tests will be performed before acceptance.<\/li>\n\n\n\n<li>State which final documents will be delivered.<\/li>\n\n\n\n<li>Confirm compatibility with existing systems.<\/li>\n\n\n\n<li>Detail exclusions and client responsibilities.<\/li>\n\n\n\n<li>Explain dependencies on infrastructure, power, network, or third parties.<\/li>\n\n\n\n<li>State warranty, support, and SLA conditions.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">All relevant answers should be recorded and incorporated into the analysis, avoiding decisions based on informal conversations.<\/p>\n\n\n\n<h2 id=\"h-quando-emitir-parecer-tecnico-de-avaliacao-de-proposta\" class=\"wp-block-heading\">When should a technical proposal evaluation opinion be issued?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In critical contracting processes, the proposal analysis should be formalized in a <a href=\"https:\/\/a3aengenharia.com.br\/conteudo\/artigos-tecnicos\/parecer-tecnico-nota-tecnica-laudo-tecnico-diferencas\/\">technical opinion<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is especially appropriate when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the contract involves high value or high risk;<\/li>\n\n\n\n<li>there is disagreement among internal areas;<\/li>\n\n\n\n<li>the decision must be technically justified;<\/li>\n\n\n\n<li>there is a question about whether to choose the lowest price;<\/li>\n\n\n\n<li>the proposals present very different scopes;<\/li>\n\n\n\n<li>the project involves a critical system;<\/li>\n\n\n\n<li>the client needs an independent recommendation on record;<\/li>\n\n\n\n<li>the analysis will be used by procurement, legal, management, or a technical committee.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The opinion does not replace the client\u2019s decision, but organizes the technical grounds so that decision is safer.<\/p>\n\n\n\n<h2 id=\"h-como-o-pmbok-apoia-a-analise-de-propostas-tecnicas\" class=\"wp-block-heading\">How does PMBOK support technical proposal analysis?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">PMBOK helps show that engineering contracting involves scope, risks, quality, stakeholders, communications, costs, procurement, and integration. Evaluating a technical proposal requires considering all these aspects.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>PMBOK area<\/th><th>Application in technical proposal analysis<\/th><\/tr><\/thead><tbody><tr><td>Scope<\/td><td>Verify compliance with requirements and deliverables<\/td><\/tr><tr><td>Quality<\/td><td>Assess technical criteria, compliance, and validation<\/td><\/tr><tr><td>Risks<\/td><td>Identify gaps, weak assumptions, and open interfaces<\/td><\/tr><tr><td>Procurement<\/td><td>Support supplier selection, contracting, and management<\/td><\/tr><tr><td>Stakeholders<\/td><td>Align procurement, engineering, operations, legal, and management<\/td><\/tr><tr><td>Communications<\/td><td>Record clarifications, decisions, and recommendations<\/td><\/tr><tr><td>Integration<\/td><td>Compare technical, contractual, and operational impacts<\/td><\/tr><tr><td>Costs<\/td><td>Assess price, life cycle, risks, and potential change orders<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This perspective prevents the proposal from being analyzed merely as a commercial document.

Engineering vs. Consulting Engineering: differences, services, and deliverables<\/a><\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-perguntas-frequentes\" class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<h3 id=\"h-como-fazer-analise-de-proposta-tecnica-de-engenharia\" class=\"wp-block-heading\">How do you analyze an engineering technical proposal?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The analysis should verify scope compliance, assumptions, exclusions, technical solution, supplier qualifications, schedule, testing, documentation, support, risks, and total cost of ownership.<\/p>\n\n\n\n<h3 id=\"h-por-que-o-menor-preco-pode-ser-arriscado-em-servicos-de-engenharia\" class=\"wp-block-heading\">Why can the lowest price be risky in engineering services?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Because the lowest price may hide incomplete scope, exclusions, poor technical quality, missing tests, insufficient documentation, or a high risk of change orders.<\/p>\n\n\n\n<h3 id=\"h-o-que-e-equalizacao-tecnica-de-propostas\" class=\"wp-block-heading\">What is technical leveling of proposals?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Technical leveling is the process of organizing differences among proposals so they can be compared on the same basis, identifying items that are included, excluded, conditional, or not stated.<\/p>\n\n\n\n<h3 id=\"h-o-que-deve-entrar-em-uma-matriz-de-avaliacao-tecnica\" class=\"wp-block-heading\">What should be included in a technical evaluation matrix?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The matrix may include scope compliance, technical solution, experience, team, schedule, testing, acceptance, support, warranty, risks, and assumptions.<\/p>\n\n\n\n<h3 id=\"h-quando-emitir-parecer-tecnico-sobre-uma-proposta\" class=\"wp-block-heading\">When should a technical opinion on a proposal be issued?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When the contracting process involves significant risk, divergent proposals, a need for technical justification, a sensitive decision, questions about price, or supplier selection.<\/p>\n\n\n\n<h3 id=\"h-como-comparar-fornecedores-com-escopos-diferentes\" class=\"wp-block-heading\">How do you compare suppliers with different scopes?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Technical leveling is required, recording what each supplier includes, excludes, conditions, or leaves unanswered. The comparison should then consider price, risk, and technical quality.<\/p>\n\n\n\n<h3 id=\"h-o-que-e-value-for-money-em-procurement-tecnico\" class=\"wp-block-heading\">What is Value for Money in technical procurement?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Value for Money is the search for the best combination of total cost, quality, and fitness for the client\u2019s objective, rather than only the lowest initial price.<\/p>\n\n\n\n<h3 id=\"h-como-identificar-exclusoes-em-uma-proposta-tecnica\" class=\"wp-block-heading\">How do you identify exclusions in a technical proposal?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Exclusions should be checked in specific proposal sections, assumptions, client responsibilities, commercial conditions, and unanswered items in the Terms of Reference.<\/p>\n\n\n\n<h3 id=\"h-preco-e-custo-total-de-propriedade-sao-a-mesma-coisa\" class=\"wp-block-heading\">Are price and total cost of ownership the same thing?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. Price is the initial contract amount. Total cost of ownership includes implementation, operation, maintenance, support, replacements, risks, and costs over the life cycle.<\/p>\n\n\n\n<h3 id=\"h-quem-deve-participar-da-avaliacao-tecnica-de-propostas\" class=\"wp-block-heading\">Who should participate in the technical evaluation of proposals?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Technical areas, operations, procurement, contract management, and, when necessary, an independent technical consultant or Owner\u2019s Engineering should participate.<\/p>\n\n\n\n<div class=\"cta-box\">\n<p><strong>Need to compare technical proposals before contracting?<\/strong><\/p>\n<p>A3A Engenharia supports clients with proposal analysis, technical leveling, evaluation matrices, technical opinions, procurement, scope review, and contracting support for critical engineering solutions.<\/p>\n<p><a class=\"btn cta-button-a3a\" href=\"https:\/\/a3aengenharia.com.br\/contato\/\">Talk to an A3A Engenharia specialist<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Learn how to analyze an engineering technical proposal using objective criteria, an evaluation matrix, technical leveling, risks, total cost, and scope compliance.<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"template":"","meta":{"_a3a_global_related_solutions":[],"_a3a_global_related_services":[],"_a3a_global_related_materials":[],"_a3a_post_lang":"en-us","_a3a_translation_group_id":"c432bd87-3c75-4095-b420-5baa404baf4f","_a3a_i18n_canonical_slug":"engineering-technical-proposal-analysis-beyond-lowest-price"},"categories":[],"segments":[],"mercados":[],"etapas":[],"class_list":["post-72953","articles","type-articles","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/articles\/72953","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/articles"}],"about":[{"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/types\/articles"}],"author":[{"embeddable":true,"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":1,"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/articles\/72953\/revisions"}],"predecessor-version":[{"id":72959,"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/articles\/72953\/revisions\/72959"}],"wp:attachment":[{"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/media?parent=72953"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/categories?post=72953"},{"taxonomy":"segments","embeddable":true,"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/segments?post=72953"},{"taxonomy":"mercados","embeddable":true,"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/mercados?post=72953"},{"taxonomy":"etapas","embeddable":true,"href":"https:\/\/a3aengenharia.com\/en-us\/wp-json\/wp\/v2\/etapas?post=72953"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
