School gym + storm shelter / Irving, Texas

Harmony Irving gym and storm shelter

How much wind should the roof supports resist?

The project adds a gym and storm shelter to a school. Before pricing the work, contractors need clear requirements for the roof and backup power. These are two questions from our review.

Finding 01

The roof notes say both 180 and 150 pounds per square foot.

One note says the steel roof supports must resist at least 180 pounds per square foot of upward force. A detail on the same sheet gives a maximum of 150. Wind can push a roof upward; the supplier needs the correct requirement to design and price the supports.

Plan note 2

180 psf

Minimum upward force to resist

Detail note 3

150 psf

Maximum upward force stated

Why it matters

A supplier could price the roof using a different requirement from the one the designer intends. The designer needs to confirm which number applies.

The question to ask

Which wind-uplift requirement should the roof-support supplier use for each support type?

What we know now: Addendum No. 1, question 66: answer deferred to the next addendum.

Finding 02

The price form includes a generator. Its size and location are not defined.

The shelter ventilation note requires backup power. The price form also includes a generator, and the written requirements mention one. In the documents reviewed, we did not find the size or location needed to price it.

Why it matters

The contractor needs to know which generator, connections and installation work to include. A symbol or a price-form line does not supply those details.

The question to ask

What generator size and location should bidders use, and which equipment must it power?

What we know now: Addendum No. 1, question 22: answer deferred. The generator is mentioned in the bid documents; this is a missing-detail finding.

Document status

In Addendum No. 1, the design team deferred answers to the generator question (22) and roof-support question (66) to a later addendum. That is the last document checked for this page. We have no confirmed cost saving or construction outcome.

These examples are questions for the project team to check. They are not a design approval or a complete review of the project. Bidders should send questions only through the owner’s official question process.

Questions about this review

What should I check before bidding on the Harmony Irving gym and storm shelter?

Mebbian’s review found two questions to clarify: roof notes with 180 and 150 pounds per square foot, and missing generator size and location details. Addendum No. 1 deferred answers to both. This page shows the drawing excerpts and the documents checked through October 27, 2026.

How do you check roof drawings before bidding?

Compare the roof plan notes with the roof detail notes. In this review, one called for at least 180 pounds per square foot of wind uplift resistance, while another gave a maximum of 150. Ask the designer which requirement applies.
