How to prepare for, lead, and evaluate contractor site visits during the bidding process
Introduction
Once you’ve sent out your bid package, the next step is to invite contractors to visit the site in person. These walkthroughs give contractors a chance to see the existing conditions, ask questions about the scope, and start thinking about how they’ll approach the job.
They also give you a chance to meet them face to face and observe how they work, communicate, and engage with your project. The better the walkthrough, the more accurate and useful the bids you receive will be.
What Walkthroughs Are and Why They Matter
Contractor walkthroughs are typically 30 to 60 minutes long and take place on-site, whether at a home, commercial space, or undeveloped lot.
Walkthroughs allow contractors to:![]()
- Assess site access, existing conditions, and unique challenges
- Clarify any gray areas in the scope of work or plans
- Take measurements or photos for reference
- Raise constructability concerns that might affect pricing
- Begin thinking through scheduling, subcontractors, and materials
They also help you:
- Meet the person or team who may build your project
- Evaluate how organized, experienced, and communicative they are
- Ask your own questions and get a feel for how the contractor works
How the Walkthrough Is Typically Scheduled
Once you’ve identified the contractors you want to meet with, you or your design team, if they are staying involved, will usually reach out to each one directly to schedule a walkthrough. This initial connection is often made by email, phone, or through a referral introduction.
Here’s how it typically goes:
- You send the bid package and briefly describe the project.
- You ask if they’re available to walk the site and provide a quote.
- The contractor responds with a few time options or requests more details.
- You confirm a date and time that works for both parties, ideally during daylight hours and when the space is accessible.
- You may send a reminder and reattach the scope or plans a day or two before the meeting.
Tip: If the property is hard to access (gated, tenant-occupied, etc.), be sure to let the contractor know in advance. This helps avoid confusion or delays the day of the walkthrough.
If you’re meeting multiple contractors, it’s fine to book them a few days apart to give yourself breathing room. Don’t feel pressured to rush through them, each meeting is a chance to learn something new about your project.
How to Prepare Before the Walkthrough
To make the meeting productive for both sides, it helps to do a bit of prep work:
- Finalize your bid package (see the previous page)
- Send it to the contractor in advance, ideally a day or two before
- Let them know the property status (occupied, vacant, under construction)
- Print a copy of your Scope of Work or plans to have on hand
- Be ready to walk through your goals, timeline, and any concerns
- Give them a way to follow up with questions after the visit
What to Observe During the Meeting
You’re not just giving a tour, you’re learning about how the contractor works. While they’re walking the job, take mental notes on things like:
- Did they show up on time and come prepared?
- Did they seem engaged and focused on your project?
- Were they reviewing your scope or plans as they walked?
- Did they take notes, measurements, or flag potential issues?
- Were they honest and realistic about timeline, scope, or unknowns?
Note: Don’t judge the meeting too harshly; this is often just the first conversation. Contractors are also evaluating whether your project is a good fit for them. It’s normal for both sides to need a little back and forth before either party feels confident moving forward. They also prefer clients who are organized, decisive, and realistic about budgets and timelines. Being professional and responsive will help attract the best contractors.
What to Share or Clarify During the Visit
You don’t need to act like a project manager, just walk them through your goals, your scope, and anything they need to know about the site. Be ready to share:
- The Scope of Work (and any gray areas)
- What parts of the project are already designed or permitted
- Known constraints: HOA restrictions, site access, utility issues
- Budget or schedule goals (if you’re comfortable sharing)
- Your decision timeline – when you expect to select a contractor
If there are specific elements you’re unsure about (e.g., structural questions, alternative finish options), it’s okay to ask for feedback. Many contractors will offer insights that can help you refine the scope before locking in pricing.
Questions to Ask Contractors During or After the Walkthrough
You don’t need to ask every question in one sitting, but these topics can help you better understand how the contractor works and whether they’re a good fit for your project.
General Background
- How long have you been in business?
- What types of projects do you typically work on?
- What areas do you serve most often?
- How many projects are you currently working on?
- What size projects do you take on?
- Do you have a contracting license in this state? What classifications?
Project-Specific Experiance
- Have you done a project like this before? Can you walk me through one in detail?
- What challenges do you anticipate based on the current site and scope?
- Are you familiar with the permitting and planning process in this city or jurisdiction?
- Are there any red flags or things I should consider changing before moving forward?
Logistics & Scheduling
- When would you realistically be able to start?
- How long do you estimate this project will take, based on what you’ve seen?
- How many people from your team would be working on the project?
- Will you be on-site regularly, or will a superintendent/foreman manage day-to-day?
- Who would be my main point of contact?
- How do you typically track progress? Do you use any specific software?
- How often do you meet with clients to go over updates or concerns?
Budget & Payment
- Do you bid fixed-price, cost-plus, or time-and-materials?
- What’s your typical payment schedule (deposit, progress payments, etc.)?
- How do you handle change orders, both in terms of cost and communication?
- Are there any typical allowances or exclusions I should expect in your bid?
- Are you able to offer value engineering ideas if the price comes in higher than expected?
Communication & Problem Solving
- What’s the best way to reach you during the project?
- How quickly do you typically respond to questions or concerns?
- How do you handle disagreements or misunderstandings with clients?
- Can you share an example of a problem on a past job and how you solved it?
- How do you approach decisions when something unexpected comes up in the field?
Subcontractors & Team
- Do you have an in-house crew, or do you mostly work with subcontractors?
- How long have you been working with your core trades (electrical, plumbing, etc.)?
- Do you let clients meet or talk to your key subs before work starts?
- Will I be able to visit the site during construction?
This list is flexible. You might ask some of these during the walkthrough and save others for a follow-up call. What matters most is getting a sense of the contractor’s experience, communication style, and approach to collaboration.
Take Notes After the Visit
Once the walkthrough is done, jot down your impressions. Things to capture:
- Did they seem detail-oriented and confident?
- Were there any red flags or communication issues?
- Did they ask smart questions or point out anything helpful?
- How well do they seem to “fit” your project and working style?
Later, when comparing bids, these notes can help guide your decision, especially if the numbers are close.
What’s Next: The Bid Collection Process
Once your walkthroughs are complete and your project is in the hands of the contractors, the next step is to wait for their bids to come in. This period often includes questions, clarifications, and minor scope refinements.
