Unfortunately, RFI responses may end up being late or not received by everyone, leading to confusion.  In all cases, RFIs cost everyone additional time prior to bid, so...the fewer, the better.  - **Unanswered pre-bid RFIs.**  If RFI responses are not received, the bidder's uncertainty increases their risk and they must include enough money in their bid to make sure potential costs are covered. - **Questions unasked by bidders.**  A savvy bidder take a calculated risk by bidding low to get the contract in anticipation of Change Orders. - **Last-minute decisions.** Some questions are never answered, leaving it up to those involved at the end of the project scrambling to get everything done as best they can.  This leads to less than optimal results that may cost the owner repeatedly over the life of the building. So, the ambiguity in a project’s plans and specifications will **directly cost the owner** more money on bid day, more money ***after*** bid day with change orders and delays that cost everyone involved.   **![canstockphoto8771312.jpg](https://blogs.heattransfersales.com/hs-fs/hubfs/Blog_images/canstockphoto8771312.jpg?width=320&name=canstockphoto8771312.jpg)How can this problem be improved or even avoided? ** Clear **communication is key**, especially early in the project.  Assemble the whole construction team at the beginning if you can (as with the design/build process).  Get early input and have everyone work together across their lines of responsibility.  **Take the extra time up front** to ask questions of the owner and of each other.  Leverage the knowledge of specialists like a good controls vendor or equipment supplier to help with the finer details.  The majority of decisions will be made during this planning and design phase through the team effort.   The team involved with this approach will have a vested interest in ensuring the plans and specifications are correct and the design intent is clear before construction gets underway.  Though it may take more time and effort up front, in the end, it will lead to **higher quality results with lower costs and happier clients!** **[![New Call-to-action](https://no-cache.hubspot.com/cta/default/715354/4df99155-a2ef-4e8f-a4fa-cfcfbed09557.png)](https://cta-redirect.hubspot.com/cta/redirect/715354/4df99155-a2ef-4e8f-a4fa-cfcfbed09557)** ###### About The Author [More from this author](https://blogs.heattransfersales.com/blog/author/joe-britt-pe) ![](https://blogs.heattransfersales.com/hs-fs/hubfs/Blog_images/Joe_Britt_blog_avatar.jpg?height=100&name=Joe_Britt_blog_avatar.jpg) ###### Joe Britt, PE Joe Britt, PE is the President of Heat Transfer Sales and interested in educating everyone about hydronic systems. #### Recommended Articles [![4 Benefits of Switching to a Hydronic HVAC System](https://blogs.heattransfersales.com/hubfs/h4qhtnb3.png)](https://blogs.heattransfersales.com/blog/4-benefits-of-switching-to-a-hydronic-hvac-system) ###### [4 Benefits of Switching to a Hydronic HVAC System](https://blogs.heattransfersales.com/blog/4-benefits-of-switching-to-a-hydronic-hvac-system) -
