VASO considers writing code to be an integral part of building a device, so the Construction Policy applies to the code as well as the physical device. If concerns arise about a team’s compliance with this policy, they will be asked to submit a copy of their code for tournament officials to review.

It is strongly recommended that teams using a kit impound a description of the substantial modification required by the Construction Policy to help the Event Supervisor verify they have met this requirement.

Section 4.b.ii.: A list of the components (including quantities or ratios of each and showing that the puck is 10% cement either by volume or by mass) used in the construction of the puck. If this information is not provided, the team's puck will earn no score, because the Event Supervisor will not be able to verify that all construction parameters have been met.

Section 3.a.: Students will build a concrete puck 4.0 ± 0.2 cm in diameter out of whatever combination of Portland cement Type I or II, sand, gravel, and water they wish. Premixed concrete mixtures are not allowed due to batch ingredient variability in these mixtures. Pucks must be at least 10% Cement…
