The addendum lands at 2 AM. The bid is updated by six.
An estimating agent watches your open bids. When the GC sends an addendum, it compares it with the set, re-checks the takeoff and drafts the question, so the morning starts with answers.

03AnswersPelles Core
Ask the bid set. Get the page back.
DoubleCheck reads every drawing, spec, addendum and contract in the set, so an estimator’s question gets an answer with the page it came from.
Who furnishes the VFDs for AHU-1 through AHU-6?

Division 23 furnishes them; Division 26 installs and wires them. The mechanical schedule and the spec agree.
23 05 13 · §1.4 · M-601Is there a liquidated damages clause, and how much?

$2,500 per calendar day after substantial completion, capped at 10% of the subcontract.
Subcontract · Art. 9.3 · p.14What in Addendum 3 touches our scope?

Four changes: feeders F4 and F9 upsized, panel LP-2 relocated, and the generator feeder added to Alternate 2.
Addendum 3 · E-401, E-601Are aluminum feeders allowed?

Yes, for feeders 100 A and larger, with compression lugs. Smaller feeders must be copper.

What teams ask before they start.
How does Pelles help preconstruction teams?
It reads the whole bid set, drawings, specs, addenda and the contract, and answers your estimators’ questions with the page cited. Compare shows every change between addenda, agents watch for new ones overnight, and apps built on Pelles hold your takeoff checks, spec matrices and proposals.
Does Pelles replace our estimating software?
No. Your estimators keep pricing in Accubid or the tools you use today. Pelles reads the documents, checks the takeoff against them and builds apps around your process, so the people who price the job spend their time on judgment instead of reading.
What does an estimating app on Pelles look like?
Whatever your team runs in spreadsheets today: a feeder schedule checked against the takeoff, a pipe spec matrix, a proposal built from your own catalogs. Pelles Build turns the spreadsheet and the process around it into an app your whole team shares.
What documents can Pelles read?
Drawings, specifications, addenda, contracts, bid forms, RFIs and schedules, from Procore, Autodesk Construction Cloud, SharePoint, Box or an upload. Every answer links back to the sheet or section it came from.
Is our project data secure?
Pelles is SOC 2 Type II attested, encrypts your data at rest (AES-256) and in transit (TLS 1.2+), keeps every customer’s data isolated, and never trains on your content. People see the projects and documents they can already open.
