Exhibit 99.1

JOINING WITH ATKINS: QUESTIONS & ANSWERS

Yes. Viewed on a pre-split basis, Atkins is paying $51.41 per share.

All shares of PBSJ stock, whether held directly by you or in your 401(k) and ESOP accounts, will be converted in the merger into the right to receive cash at the $17.137 price per share. Restricted stock will become fully vested and will be treated the same as other shares. Atkins stock is not being offered in the merger.

Shortly following the effectiveness of the merger, you will receive instructions from the paying agent as to how to exchange your stock certificates (and uncertificated shares) and receive payment for your shares that are held by you directly (as opposed to those shares held for your account in the ESOP and 401(k) plans). In addition, the paying agent will also send you a document known as a “letter of transmittal” for you to complete and return together with your stock certificates. For your directly owned shares, you will be issued a check from the paying agent, who will deduct any applicable withholding taxes, shortly after you submit your certificates and the letter of transmittal in accordance with the paying agent’s instructions. If you received a loan from PBSJ secured by your shares, then you will receive the difference between the price being paid for the shares and the unpaid balance of the loan.

For shares held for your ESOP and 401(k) accounts, payment in cash will be made to Charles Schwab as the trustee and allocated to your account. We will provide you with information regarding your alternatives for the distribution of this cash once we have determined the treatment of the 401(k) plan, which we expect to occur soon.

No.

The company will be able to provide the shareholder with the cost basis information it has on file; however, it is ultimately the shareholder’s responsibility to verify this information.

No, we will not be offering any investment advice other than that currently offered to 401(k) participants through Charles Schwab.

Atkins stock will not be a direct investment option under the Schwab 401(k) program, unless you are a participant in the Schwab Personal Choice program. Please contact Charles Schwab for details.

There currently are no plans to eliminate the KECAP program; however, the plan is being reviewed in connection with the transaction.

Yes, we expect that it will, assuming shareholder and regulatory approvals are received in the expected time frames.

Funds in the ESPP will be applied to purchase shares of PBSJ stock at a price per share of $11.79 (90% of the September 30, 2009, price per share of $13.10) immediately prior to the effectiveness of the merger. The shares that will be acquired will be paid for in the merger at $17.137 per share like any other outstanding share of PBSJ stock. You will be issued a check from the paying agent for the merger consideration of $17.137 per share in respect of any ESPP shares, less any applicable withholding taxes.

Contributions to the ESPP will terminate with the payroll check issued on August 20, 2010. If you were not an ESPP participant on August 1, 2010, you will not be able to enroll now.

No, the company match to employees’ 401(k) contributions for 2010 will not be done prior to the merger. We anticipate that the timing of the 401(k) match will not change

At this time, we anticipate that PBSJ’s current benefit programs will remain in place. However, the ESOP component of the 401(k) plan will terminate following the merger because all PBSJ stock will be owned by Atkins at that time. The new owners will determine the nature of future benefit programs.

2

The current vesting period requirements of the 401(k) will not change.

The 401(k) plan is unaffected by the transaction, other than the replacement of PBSJ shares with cash and the termination of the ESOP component of the plan.

Restricted stock will become fully vested and cashed out upon the effectiveness of the merger like any other outstanding share of PBSJ stock. The merger consideration of $17.137 per share, less applicable income tax withholding, will be distributed via check by the paying agent.

Atkins does not have an ESPP. Consult your stock broker if you are interested in purchasing Atkins stock in the open market.

Per Atkins’ Chief Executive Keith Clarke, there will be no immediate changes to existing benefit programs as a result of the merger. However, Atkins may in the future determine to modify benefits and compensation policies as permitted by the terms of PBSJ’s existing benefit plans and policies and applicable law.

Yes.

We do not anticipate any changes in those hours as a result of the merger. However, Atkins may in the future determine to modify benefits and compensation policies as permitted by the terms of PBSJ’s existing benefit plans and policies and applicable law.

Your years of service for vacation will remain based on your original date of hire.

That obligation will remain. There are no changes as a result of this transaction.

3

That will be addressed by the Transition Team.

That will be addressed by the Transition Team.

Yes. However, Atkins may in the future determine to modify benefits and compensation policies as permitted by the terms of PBSJ’s existing benefit plans and policies and applicable law.

That will be addressed by the Transition Team.

That will be addressed by the Transition Team.

We do not anticipate that there will be any change in your H-1B status or green card filing as a result of the merger. However, you should consult the Director of Human Resources for more information.

We anticipate that the PBS&J name will change to Atkins on April 1, 2011, however, PRBC will continue to operate under the Peter R. Brown Construction, Inc. name.

We anticipate that they will remain separate. Interfacing will be addressed by the Transition Team.

While the SOX rules will no longer directly apply to us, the UK has its own rules (called Turnbull) that will. Internal controls will still be important and are expected to remain in place following the merger.

4

It is expected that we will continue to prepare our financial statements on a daily basis following U.S. GAAP, and track and adjust IFRS differences separately, so that we can report on either basis.

Yes.

Yes, and they will change to March 31 at the appropriate time.

It should have no significant effect.

Generally not, but this will be reviewed by the Transition Team.

Yes, PBS&J will still need overhead audits and will still need to comply with DCAA/FAR/CAS as long as we perform work for the U.S. federal government and state governments with similar requirements.

That is the decision of the individual business units, although there are certain limitations imposed on PBSJ under the merger agreement.

Atkins uses JD Edwards. We will initially continue to use our existing systems.

We anticipate that we will.

Yes. We will prepare a 12-month budget now for October 1, 2010 and then in early 2011 prepare a new 12-month budget starting April 1, 2011.

5

We anticipate that there will be.

A wholly owned subsidiary is a company whose stock is completely owned by its parent company. For example, today Post, Buckley, Schuh & Jernigan, Inc. (“PBS&J”) is a wholly owned subsidiary of The PBSJ Corporation, and the stock of The PBSJ Corporation is owned by our shareholders. Therefore, PBS&J is a wholly owned subsidiary of The PBSJ Corporation. Following the merger, WS Atkins plc will own all of the stock of The PBSJ Corporation, and The PBSJ Corporation will be a wholly owned subsidiary of Atkins. PBS&J and Peter R. Brown Construction, Inc. will remain wholly owned subsidiaries of The PBSJ Corporation, but they will ultimately be owned by Atkins. Former PBSJ shareholders will no longer be owners of The PBSJ Corporation.

To our knowledge, Atkins has no current intention to sell Peter Brown Construction or any other part of PBSJ after the acquisition, though they have indicated their intention to shut down the operations of PBS&J International, Inc.

Atkins does not currently perform construction management at risk. However, they do provide certain low risk construction services in the UK.

That will be addressed by the Transition Team.

Yes, but it will have a foreign owner.

We expect that the impact will be minimal, but this is being addressed in the regulatory reviews necessary to complete the transaction.

We do not anticipate any change from our current practice.

Atkins is headquartered in Epsom, not far from London.

You can read about Faithful + Gould on the Internet at www.fgould.com

We understand that there is no intention to reorganize PBS&J at this time.

Their annual report (see http://ar2010.atkinsglobal.com/) provides a good overview of their worldwide operations.

Atkins has typically grown through organic growth. Acquisitions have historically been very targeted and focused on adding skills or specific geographies. Their last acquisition was a 20-person firm specializing in the design of mechanical equipment in the nuclear sector. Before that they bought a 200-person company in the defense sector.

Information will be provided in the proxy to assist shareholders in evaluating the financial aspects of the transaction, regarding the background and process by which the merger was agreed to, as well as the reasons for the merger and certain other matters required by the Securities and Exchange Commission. There will be limited information on benefits, because the proxy is designed to present information that is material to the decision of a shareholder as such, rather than as an employee.

We understand that consolidation of staff was not part of the business case for Atkins to acquire PBSJ. The fact that we had already taken the necessary steps to strengthen our financial position was viewed as a positive. They are looking to grow their presence in the US. Nevertheless, once the merger is completed, Atkins, as the owner of PBSJ, will be entitled to review and adjust work force levels as it deems appropriate.

Wayne Overman (PBSJ) and Graham Roberts (Atkins) will lead the Transition Team. Members of management from both firms will be participating. You can send Wayne comments or questions.

7

Following the merger, PBSJ will continue to have a Board of Directors, the members of which will be persons designated by Atkins and whose fiduciary obligations will be to Atkins, the ultimate shareholder.

We are still PBSJ and doing business as PBSJ until the merger is consummated. Following the merger, we would inform the client that both firms are wholly owned subsidiaries of Atkins.

We are still PBSJ and doing business as PBSJ until the merger is consummated.

We do not anticipate that any of our local government contracts will be affected by the merger. Any concerns should be addressed to the Transition Team.

Firms team with us because of the skills our employees bring to the project. We hope that will not change with this transaction and, given Atkins’ areas of expertise, we may be able to bring more resources to the table.

Generally no, but this will be reviewed by the Transition Team

These issues will be worked out by the Transition Team; however, Atkins is aware of PBSJ’s revenue recognition policies, and major changes are not anticipated.

Absolutely continue to pursue work as normal! However, given certain restrictions on our activities pending the merger, new projects and resource commitments must be discussed with your Group President, and any project or teaming activities that involve Atkins should be discussed with Wayne Overman.

No!

Atkins’ 2010 Annual Report (http://ar2010.atkinsglobal.com/) provides a good overview of their major markets.

Not at this time. Those discussions, if appropriate, will be addressed by the Transition Team.
