Nature of the Service
ConcursArq.com operates as a digital platform for publishing, managing, moderating and selecting conceptual design proposals through contests.
The platform allows clients to publish design contests and allows registered designers, architects, engineers, students or creative professionals to submit proposals according to the brief, deliverables, deadlines and conditions established for each contest.

Territorial Scope
ConcursArq.com has an international vision and may be used by users located in different countries, subject to platform availability, legal restrictions, payment availability and operational feasibility.
The user acknowledges that laws related to architecture, construction, professional practice, intellectual property, consumer protection, data protection, taxation and electronic payments may vary by country, state, city or jurisdiction.
Each client is responsible for verifying the legal, technical, urban planning, municipal, structural and construction feasibility of any proposal before using or executing it.
Each designer or participant is responsible for complying with the laws applicable to their country, profession, academic status, taxation, copyright obligations and personal responsibilities.

Create an account.
Publish a contest.
Participate in a contest.
Submit a proposal.
Make a payment.
Request a withdrawal.
Use the client, designer, jury or administrator panel.
Interact with any function of the platform.
If the user acts on behalf of a company, architecture studio, university, institution or third party, the user declares that they have sufficient authorization to accept these terms on behalf of that entity.
Types of Users
The platform may include the following types of users:
Client: an individual, company, institution, architecture studio, builder, contractor, real estate professional or entity that publishes a contest and funds the corresponding prize.
Designer or participant: a user who applies to and submits proposals for contests. This may include architects, engineers, designers, students or creative professionals, depending on the conditions of each contest.
Jury member or professional advisor: a specialized user who may participate in evaluations, recommendations or conceptual reviews when hired, appointed or enabled by the platform or by the client.

User Registration
To use certain functions, the user must register and provide true, updated and verifiable information.
The user agrees to:
Not create false accounts.
Not impersonate another person or entity.
Not use third-party data without authorization.
Keep their password secure.
Update their information when necessary.
Not share their account with unauthorized third parties.
ConcursArq.com may request additional information to verify identity, country, city, experience, payment details, withdrawal information, contact information or any other information required to properly operate the service.
Publishing Contests
The client may publish a contest indicating, among other information:
Type of project.
Approximate area.
Reference location.
Design objectives.
Expected deliverables.
Participation deadline.
Estimated number of participants.
Prize offered.
Special contest conditions.
The client declares that they have the right to request design proposals for the property, space, land, business or project described, and that the information shared does not violate the rights of third parties.
ConcursArq.com may review, observe, edit, reject or request corrections for contests that are confusing, incomplete, fraudulent, illegal, offensive or inconsistent with the purpose of the platform.
Client Payments
Unless a different rule is stated in a promotion, specific agreement or contest page, the general payment flow is as follows:
The client makes an initial payment equivalent to 50% of the total contest value to activate the contest.
Participating designers develop and submit their proposals.
ConcursArq.com moderates and verifies the submitted proposals.
Before viewing the complete verified proposals, the client must make the final payment equivalent to the remaining 50% of the contest value.
Once the final payment is completed, the client may review the enabled proposals, select finalists and choose the winner according to the contest rules.
The initial payment activates the contest, mobilizes participation, supports platform operation and reserves the process. For this reason, it may be non-refundable, unless otherwise decided by ConcursArq.com or required by applicable law.
Platform Commission
ConcursArq.com may charge a commission for the use of the platform, contest management, moderation, support, operational processing, promotion, digital tools and system administration.
The standard ConcursArq.com commission may be up to 20% of the total contest value, unless another condition is stated on the contest page, in a promotion, commercial plan, specific contract or individual agreement.
The net prize visible to the designer may reflect deductions for platform commission, banking fees, payment gateway fees, taxes, currency conversion fees or other applicable costs.
Failure to Pay the Final Balance
If the client does not pay the final balance equivalent to the remaining 50% of the total contest value, ConcursArq.com may restrict full access to the verified proposals.
Before the final payment, the client may only see limited information, such as the number of verified proposals, general status notices, system alerts and, optionally, protected previews, blurred views, watermarked images or previews without sufficient detail to copy the design.
Once ConcursArq.com notifies the client that verified proposals are ready for review, the client will have a maximum period of five (5) calendar days to complete the final payment and fulfill their payment commitment.
If the client makes the payment within the stated period, the client may access the verified proposals, select finalists and choose the winner according to the contest rules.
If the client does not make the final payment within the five (5) calendar day period, the client will be considered to have failed to comply with their payment commitment and will lose the right to view, use, copy, download, adapt, execute or benefit from the submitted proposals.
In such case, ConcursArq.com may convert the contest into a public voting, showcase, exposure or promotional dynamic among the proposals that were verified and that met the minimum deliverables.
The winner of such public dynamic may be determined by likes, votes, reactions, internal voting, social media voting, public voting or any other mechanism defined and communicated by ConcursArq.com for that case.
When this rule is activated due to the client’s failure to pay, the alternative prize for the winner of the public voting dynamic will be equivalent to 30% of the initial payment made by the client, meaning thirty percent of the fifty percent initially paid to activate the contest.
The ConcursArq.com commission for operation, management, moderation, administration, support and use of the platform will remain subject to the economic rules of the contest.
The client accepts that, in case of failure to complete the final payment within the indicated period, they will not be entitled to claim a refund of the initial payment, use of proposals, winner selection, full access to deliverables or rights over the submitted designs.
This measure is intended to protect the work of participating designers and prevent verified proposals from remaining without recognition or closure due to the client’s failure to complete payment.
Designer Participation
Designers must submit original proposals developed by themselves or by their authorized team.
Each designer agrees to:
Not plagiarize proposals.
Not use third-party material without authorization.
Not submit offensive, illegal or misleading content.
Comply with the minimum deliverables indicated.
Respect contest deadlines.
Not contact the client outside the platform to evade rules, commissions or processes.
Not manipulate votes, likes, finalists or results.
ConcursArq.com may observe, reject, hide or remove proposals that do not comply with technical, formal, ethical or legal requirements.
Deliverables
Deliverables may include, depending on each contest:
Floor plans.
Sections.
Elevations.
Renderings.
Conceptual images.
Diagrams.
Reference details.
PDF boards.
Conceptual narrative.
Other documents indicated in the brief.
Editable files, 3D models, CAD files, BIM files, SketchUp files, Chief Architect files, Revit files or other source formats are not included unless expressly stated in the contest brief or agreed through an additional payment or written agreement.
Proposal Moderation
ConcursArq.com may moderate proposals before displaying them to the client.
Proposals may be classified as:
Approved or verified: the proposal meets the minimum deliverables and may be viewed according to the contest rules.
Observed: the proposal requires corrections or additional information within the permitted period.
Denied: the proposal does not meet the minimum requirements, contains insufficient, fraudulent, offensive, copied or out-of-brief content.
Moderation does not imply technical certification, construction approval, code compliance verification or professional validation for executing a project.
Selection of Finalists and Winner
The client may select finalists from the verified proposals. The platform may establish a maximum number of finalists, commonly up to five highlighted proposals.
If a contest receives fewer verified proposals than the maximum number of finalists, the client may select fewer finalists according to the number of available verified submissions. For example, if there is only one verified proposal, the client may select that proposal as the winner, provided that the platform rules allow it.
Among the finalists, the client will select one economic winner, unless the contest brief indicates a different rule.
Secondary placements, finalist recognition, public likes, social voting, mentions or visibility dynamics may have promotional, reputational or showcase purposes and do not necessarily generate an additional economic prize.
Final Adjustment Round
When enabled by the platform, there may be a final adjustment round for finalists.
Observations must be private, specific to each proposal and visible only to the corresponding designer.
The duration of this round will be the period indicated by the platform or by the contest brief.
If a final adjustment round is opened, each finalist may receive specific observations and may submit an adjusted version within the established period.
The platform may establish a fixed deadline for this round, and the client may not modify such deadline unless ConcursArq.com authorizes it.
Winner Selection and Contest Closure
Once the client selects a winning proposal, the selected proposal will be marked as the official winner of the contest.
The winner selection may trigger notifications to the designer, the client and/or the platform administrators.
After a winner is selected, the contest may move to a closing process that includes registration of the winner, prize management, certificate generation, access to deliverables and administrative review.
Once the contest is finalized, it may appear in the finished contests section, public showcase, portfolio areas, winner galleries or promotional materials, subject to the privacy and intellectual property rules established by the platform.
Prizes and Withdrawals
Prize payment is subject to:
Confirmation of the winner.
Designer identity validation.
Compliance with deliverables.
Absence of pending claims.
Availability of funds.
Platform withdrawal rules.
Banking fees, payment gateway fees, currency conversion fees or applicable taxes.
ConcursArq.com may request payment details, country, identification information, withdrawal method, bank account, PayPal account or another enabled method.
The designer is responsible for declaring and paying any applicable taxes in their country or jurisdiction.
ConcursArq.com may process prize withdrawals according to fixed cut-off dates, internal review periods, account verification requirements, micro-deposit verification or other security procedures.
Prize payments may be made in USD. Payment providers, banks, PayPal or other services may apply conversion fees, commissions, processing times or local requirements.
Wallet, Payment Accounts and Withdrawal Verification
ConcursArq.com may provide a wallet, prize balance, withdrawal history, payment status or internal financial dashboard for designers.
The wallet may display official prizes, withdrawal requests, paid amounts, pending balances, verified accounts, micro-deposits or other financial records.
Certain amounts displayed for testing, administrative adjustment, micro-deposit verification or internal accounting may not represent official contest prizes unless clearly identified as official prize amounts from a completed contest.
ConcursArq.com may require verification of withdrawal accounts before processing payments, including micro-deposits, account ownership confirmation, PayPal verification, banking information review or additional documentation.
The platform may reject, pause or delay withdrawals if there are inconsistencies, suspected fraud, identity issues, duplicate accounts, payment disputes or incomplete information.
Certificates and Recognitions
ConcursArq.com may issue digital certificates, participation records, finalist recognitions, winner certificates or other digital credentials.
Certificates may include participant name, contest title, proposal title, placement, issue date, verification code and public verification URL.
Certificates are digital recognitions generated by the platform and do not constitute a professional license, academic degree, government certification or authorization to practice architecture, engineering or construction.
ConcursArq.com may update the design, format, verification method or availability of certificates at any time.

ConcursArq.com may offer free or paid plans for designers, clients, jury members or professional users.
